Description

Technical Field

[0001] The invention relates to a thermal insulation and decoration method for the inner surface of a roof and a wall, in particular to an indoor noise reduction and radiation reduction strong thermal insulation method and an inner decoration layer construction system thereof. Background Art

[0002] Advances in building insulation technology, particularly the widespread use of exterior walls and roof insulation, double-glazing, and thermally insulated doors and windows, have significantly reduced building energy consumption. However, insulation is a relative phenomenon; there's still a significant temperature difference between the interior and exterior walls, and the interior walls and roof still release heat in the summer and absorb it in the winter. Furthermore, interior surfaces prioritize visual appeal, and the visual effects of commonly used insulation materials often don't meet people's aesthetic standards. Further advancements in existing indoor insulation technologies could eliminate heating requirements or significantly reduce heating intensity, even allowing for simple, energy-saving heating technologies to ensure comfortable winter temperatures. However, the reality is that suitable technologies are unavailable.

[0003] Noise, especially nighttime noise during sleep, is a pressing issue for those who appreciate a quiet environment, especially those suffering from insomnia. While building sound insulation technology has made significant progress, for those who prefer a quiet environment, indoor sound insulation and noise reduction technology still urgently needs innovation.

[0004] Electromagnetic radiation is everywhere. It is difficult to tune into a radio station using traditional mechanical radio tuning. This is enough to prove that electromagnetic pollution has become very serious. Therefore, reducing electromagnetic radiation and improving the health of the indoor radiation environment through innovative interior decoration technology is also a problem that needs to be solved urgently. Summary of the Invention

[0005] The purpose of the present invention is to overcome the above-mentioned defects of the prior art and provide a method for indoor noise reduction, radiation reduction and strong thermal insulation. The present invention also relates to an interior decoration layer construction system for implementing the method.

[0006] To achieve the above-mentioned purpose, the indoor noise reduction, radiation reduction and strong thermal insulation method of the present invention is special in that a special reflective film for floor heating is adhered to the inner surface of the universal indoor wall, or a foamed resin insulation layer and an aluminum foil reflective layer are adhered in sequence, and then covered with wall cloth or wallpaper or flocking cloth or self-adhesive wall cloth or self-adhesive wallpaper or self-adhesive flocking cloth, so as to achieve noise reduction, radiation reduction and heat insulation on the inner surface of the universal indoor wall; the inner surface of the universal roof is covered with wall cloth or wallpaper or flocking cloth or self-adhesive wall cloth or self-adhesive wallpaper or self-adhesive flocking cloth, so as to achieve heat insulation on the inner surface of the universal roof. The strong thermal insulation is an indoor thermal insulation for strengthening thermal insulation on the basis of the external thermal insulation of the building. Compared with adhering a special reflective film for floor heating in sequence, the construction of the adhesive can be significantly simplified. Compared with non-self-adhesive adhesive, the adhesive construction is easier, and there is no trouble of brushing glue, pollution, or discoloration during long-term use. Wall cloth and wallpaper offer a highly decorative effect and resist shedding. Wallpaper is easier to clean. Wall cloth offers superior thermal insulation and visual flexibility compared to wallpaper, while flocking offers even better thermal insulation and visual flexibility. The foamed resin insulation layer provides inward insulation and soundproofing, while the aluminum foil reflective layer reflects infrared and electromagnetic radiation. The flocking fabric can be either electrostatic or woven. Specifically, the flocking layer effectively prevents convection heat transfer between indoor airflow and the interior surfaces of the ceiling and walls. This creates a flocking air cushion, effectively isolating indoor air from transferring heat to the flocking layer and from the flocking layer to the indoor airflow. The foamed resin insulation layer, aluminum foil reflective layer, and flocking fabric collectively provide sound insulation, reduce electromagnetic radiation, and provide strong thermal insulation, significantly reducing energy consumption while creating a quiet and comfortable indoor environment. Flocking fabric offers the best thermal insulation. Trial testing has verified that in cold winters in Shandong and Lhasa, indoor spaces employing the indoor noise reduction, radiation reduction, and strong thermal insulation method and its interior decorative layer construction system can maintain temperatures of 16-20°C and 15-18°C, respectively, without heating. In cold winters in Jilin, indoor spaces employing the indoor noise reduction, radiation reduction, and strong thermal insulation method and its interior decorative layer construction system can maintain temperatures of 12-15°C, respectively, with low-intensity heating. In indoor spaces employing the indoor noise reduction, radiation reduction, and strong thermal insulation method and its interior decorative layer construction system, Wi-Fi signals are weakened and radio signals are affected. For example, the signal improves near walls and weakens away from walls, demonstrating a true radiation reduction effect. In the same room, the user who used the indoor noise reduction, radiation reduction, and strong thermal insulation method and its interior decorative layer construction system of the present invention was more likely to fall asleep and sleep deeply, while the user who did not used the indoor noise reduction, radiation reduction, and strong thermal insulation method and its interior decorative layer construction system of the present invention was relatively less likely to fall asleep and sleep deeply. Intuitively, the room with the decoration was much quieter than the one without the decoration, indicating that the noise insulation and noise reduction effect was also significant. Therefore, the multiple functions of noise reduction, radiation reduction, and strong thermal insulation significantly save heating and cooling energy while creating a quiet, healthy, and comfortable indoor environment for people.

[0007] As an optimization, the interior walls and ceilings of bathrooms or toilets can be covered with a reflective film specifically designed for floor heating, or with a foam resin insulation layer and an aluminum foil reflective layer to achieve noise reduction, radiation reduction, and thermal insulation. This composite foam resin insulation layer and aluminum foil reflective layer not only effectively insulates the interior, but also prevents radiant heat transfer through the aluminum foil reflective layer, significantly saving energy for heating and cooling. In particular, in cold winter months, minimal or no heating is required to meet the required temperature for bathing. The aluminum foil reflective layer is also more resistant to moisture.

[0008] As an optimization, the floor heating reflective film is made of a composite material consisting of a foam resin base layer and an aluminum foil reflective surface layer that is narrower than the foam resin base layer. This allows for two layers to be applied simultaneously, significantly improving installation efficiency. This significantly reduces installation costs, as the aluminum foil reflective surface layer alone is significantly more expensive than the floor heating reflective film. Furthermore, manual application is generally more effective than factory-installed reflective film using specialized equipment. In particular, the pleated aluminum foil reflective surface layer offers higher radiation rejection and thermal insulation compared to flat film.

[0009] The surface of the floor heating reflective film applied to the interior walls of general interiors can be covered with self-adhesive wall covering, self-adhesive wallpaper, or self-adhesive flocking cloth. This allows the gaps between adjacent aluminum foil reflective layers to allow mobile phone, Wi-Fi, and radio signals to pass through freely, avoiding excessive shielding of the corresponding wireless transmission signals. Alternatively, adjacent surfaces of the floor heating reflective film applied to the interior walls of general interiors can be covered with a self-adhesive aluminum foil layer covering the foam resin base of the floor heating reflective film. The aluminum foil reflective layer and the self-adhesive aluminum foil layer can then be covered with self-adhesive wall covering, self-adhesive wallpaper, or self-adhesive flocking cloth. This additional self-adhesive aluminum foil layer covering the foam resin base of the floor heating reflective film can enhance noise reduction, radiation reduction, heat insulation, and thermal insulation, providing a quieter and more comfortable indoor environment.

[0010] The inner surface of the wall and the inner surface of the ceiling of the toilet or bathroom are covered with the special reflective film for floor heating, and the adjacent surface is adhered with a self-adhesive aluminum foil decorative layer covering the foam resin base of the special reflective film for floor heating; or the inner surface of the wall and the inner surface of the ceiling of the toilet or bathroom are covered with the special reflective film for floor heating, and the self-adhesive aluminum foil decorative layer is adhered to the surface.

[0011] The adjacent seams of the floor heating-specific reflective film are arranged to ensure flatness; or the adjacent seams of the aluminum foil reflective surface layer are arranged, and the adjacent overlapping seams of the foamed resin base layer are arranged. Although the flatness is worse, it can avoid shielding holes on both sides of the foamed resin base layer without the aluminum foil reflective surface layer, thereby ensuring the complete anti-radiation performance of the wall.

[0012] The self-adhesive wall cloth, self-adhesive wallpaper or self-adhesive flocking cloth are arranged adjacent to each other at the seams, which is convenient for adhesion; or the self-adhesive wall cloth, self-adhesive wallpaper or self-adhesive flocking cloth are arranged adjacent to each other at the seams, which has good flatness.

[0013] Seam covering strips or decorative metal foil strips can be installed at adjacent joints between self-adhesive wall coverings, wallpapers, or flocking sheets on the interior surfaces of common ceilings. Alternatively, seam covering strips or decorative metal foil strips can be installed at adjacent joints between self-adhesive wall coverings, wallpapers, or flocking sheets on the interior surfaces of common interior walls and ceilings. This not only conceals the seams but also prevents heat transfer nodes. Seam covering strips on homogeneous self-adhesive wall coverings, wallpapers, or flocking sheets help prevent visual fatigue. Metal foil decorative strips can enhance the visual environment and add color to the interior.

[0014] As an optimization, the foamed resin insulation layer or the floor heating reflective film composed of a foamed resin base layer and an aluminum foil reflective surface layer narrower than the foamed resin base layer is bonded to the inner surface of the general indoor wall, the inner surface of the general indoor ceiling, the inner surface of the wall and the inner surface of the ceiling of the bathroom or washroom through a spacer of foamed double-sided tape. The spaced arrangement of the foamed double-sided tape can form an air cushion that is very conducive to noise reduction in the space between the inner surface of the wall or the inner surface of the ceiling and the foamed resin insulation layer or the floor heating reflective film, that is, it can absorb noise energy through the widely distributed interlayer air cushion, play a good noise reduction role, especially absorb and eliminate the micro-noise energy that seriously affects people's sleep, and create a quieter and more comfortable indoor environment. More specifically, the foamed resin insulation layer or the floor heating reflective film foamed resin base layer is spaced between the inner surface of the wall or the inner surface of the ceiling, which can significantly enhance the thermal insulation performance and further improve the energy-saving benefits of heating and cooling.

[0015] The distance between adjacent foam double-sided tapes is limited to prevent the foam resin insulation layer or the foam resin base layer of the special reflective film for floor heating from not being attached to the inner surface of the wall or the inner surface of the ceiling after bonding. This not only ensures the effectiveness of the noise reduction air cushion, but also plays a very effective heat insulation role by not contacting the heat transfer surface. The adjacent surfaces of the spaced foam double-sided tapes are cross-arranged, and the cross-bonding can significantly enhance the bonding strength, and avoid the disadvantage of the foam resin insulation layer or the foam resin base layer of the special reflective film for floor heating being easily attached to the inner surface of the wall or the inner surface of the ceiling when bonding in the forward direction.

[0016] As an optimization, first apply a narrow vertical strip of self-adhesive wall covering, wallpaper, or flocking to the inner corner of the wall, ensuring a smooth application of the strip. Then, apply the wide strip of self-adhesive wall covering, wallpaper, or flocking to the adjacent wall, overlapping the strips. This solves the problem of large, unavoidable wrinkles on the wide strip of self-adhesive wall covering, wallpaper, or flocking that extend into the inner corner.

[0017] Light-colored self-adhesive wall coverings, wallpaper, or flocking fabrics are applied as a base surface to the interior surfaces of common interior walls and ceilings, respectively. At the junction of the interior walls and ceilings on the base surface, a top inner perimeter strip, top edge strip, or top inner corner strip of the same or darker color as the light-colored self-adhesive wall coverings, wallpaper, or flocking fabric is applied. Alternatively, rigid interior and exterior corner decorative strips are nailed or attached to the junction of the interior walls and ceilings on the base surface and at the interior and exterior corners of the common interior walls. Tonal border strips help reduce visual fatigue, while dark-colored border strips help visually separate the wall and ceiling, enhancing the sense of visual space. Rigid interior and exterior corner decorative strips can enhance the sense of visual space in the room. The ceiling inner perimeter strip can enhance the visual sense of width by outlining the perimeter of the ceiling inner surface. The inner top edge of the wall can enhance the visual sense of wall support by providing an outline. The inner corner trim can enhance the visual sense of ceiling width and wall support by providing an outline, further enhancing the three-dimensional effect of the interior ceiling. Rigid inner and outer corner trims can further enhance the three-dimensional effect of the interior.

[0018] The interior decorative layer construction system used to implement the indoor noise and radiation reduction and enhanced thermal insulation method of the present invention is unique in that it adheres a reflective film specifically for floor heating to the interior surfaces of common interior walls, or sequentially adheres a foamed resin insulation layer and an aluminum foil reflective layer, along with wall covering, wallpaper, flocking, self-adhesive wall covering, wallpaper, or flocking, and a wall covering, wallpaper, or flocking. The enhanced thermal insulation is achieved by enhancing indoor thermal insulation in addition to the building's exterior insulation. Applying a reflective film specifically for floor heating significantly simplifies the installation process compared to sequentially applying a foamed resin insulation layer and an aluminum foil reflective layer. Self-adhesive coatings are easier to apply than non-self-adhesive coatings, eliminating the hassle of applying glue, pollution, and discoloration over long-term use. Wall coverings and wallpaper offer excellent decorative effects and resist shedding. Wallpaper is easier to clean. Wall coverings offer superior thermal insulation and visual flexibility compared to wallpaper, while flocking offers superior thermal insulation and visual flexibility compared to wall coverings. The foamed resin insulation layer provides inward insulation and soundproofing, while the aluminum foil reflective layer reflects infrared and electromagnetic radiation. The flocking fabric can be either electrostatic or woven. Specifically, the flocking layer effectively prevents convection heat transfer between indoor airflow and the interior surfaces of the ceiling and walls. This creates a flocking air cushion, effectively isolating indoor airflow from transferring heat to the flocking base, or from the flocking base to the indoor airflow. The foamed resin insulation layer, aluminum foil reflective layer, and flocking fabric work together to provide sound insulation, reduce electromagnetic radiation, and provide strong thermal insulation, significantly reducing energy consumption while creating a quiet and comfortable indoor environment. Flocking fabric offers the best thermal insulation. Trial testing has verified that in cold winters in Shandong and Lhasa, indoor spaces employing the indoor noise reduction, radiation reduction, and strong thermal insulation method and its interior decorative layer construction system can maintain temperatures of 16-20°C and 15-18°C, respectively, without heating. In cold winters in Jilin, indoor spaces employing the indoor noise reduction, radiation reduction, and strong thermal insulation method and its interior decorative layer construction system can maintain temperatures of 12-15°C, respectively, with low-intensity heating. In indoor spaces employing the indoor noise reduction, radiation reduction, and strong thermal insulation method and its interior decorative layer construction system, Wi-Fi signals are weakened and radio signals are affected. For example, the signal improves near walls and weakens away from walls, demonstrating a true radiation reduction effect. In the same room, the user who used the indoor noise reduction, radiation reduction, and strong thermal insulation method and its interior decorative layer construction system of the present invention was more likely to fall asleep and sleep deeply, while the user who did not used the indoor noise reduction, radiation reduction, and strong thermal insulation method and its interior decorative layer construction system of the present invention was relatively less likely to fall asleep and sleep deeply. Intuitively, the room with the decoration was much quieter than the one without the decoration, indicating that the noise insulation and noise reduction effect was also significant. Therefore, the multiple functions of noise reduction, radiation reduction, and strong thermal insulation significantly save heating and cooling energy while creating a quiet, healthy, and comfortable indoor environment for people.

[0019] As an optimization, the interior walls and ceilings of bathrooms or toilets can be covered with reflective film specifically designed for floor heating, or with a foam resin insulation layer and an aluminum foil reflective layer. This composite foam resin insulation layer and aluminum foil reflective layer not only effectively insulates the room but also prevents radiant heat transfer through the aluminum foil reflective layer, significantly saving energy for heating and cooling. In particular, in cold winter months, minimal or no heating is required to maintain the desired temperature for bathing. The aluminum foil reflective layer is also more resistant to moisture.

[0020] As an optimization, the special reflective film for floor heating is composed of a composite of a foamed resin base layer and an aluminum foil reflective surface layer narrower than the foamed resin base layer. In this way, sticking two layers at a time can significantly improve the sticking efficiency. Since the installation cost of a single aluminum foil reflective surface layer is extremely high compared to the special reflective film for floor heating, the installation cost can be significantly reduced. In addition, manual installation is always better than the special reflective film for floor heating installed by special equipment in the factory. In particular, the aluminum foil reflective surface layer with pleats on the special reflective film for floor heating has higher anti-radiation and heat insulation quality than flat film.

[0021] The surface of the floor heating reflective film applied to the interior walls of general interiors can be covered with self-adhesive wall covering, self-adhesive wallpaper, or self-adhesive flocking cloth. This allows the gaps between adjacent aluminum foil reflective layers to allow mobile phone, Wi-Fi, and radio signals to pass through freely, avoiding excessive shielding of the corresponding wireless transmission signals. Alternatively, adjacent surfaces of the floor heating reflective film applied to the interior walls of general interiors can be covered with a self-adhesive aluminum foil layer covering the foam resin base of the floor heating reflective film. The aluminum foil reflective layer and the self-adhesive aluminum foil layer can then be covered with self-adhesive wall covering, self-adhesive wallpaper, or self-adhesive flocking cloth. This additional self-adhesive aluminum foil layer covering the foam resin base of the floor heating reflective film can enhance noise reduction, radiation reduction, heat insulation, and thermal insulation, providing a quieter and more comfortable indoor environment.

[0022] Applying a self-adhesive aluminum foil decorative layer over the foam resin base of the floor-heating reflective film to the interior walls and ceilings of bathrooms or toilets simplifies installation and enhances decorative style. Alternatively, applying a self-adhesive aluminum foil decorative layer over the floor-heating reflective film to the interior walls and ceilings of bathrooms or toilets significantly improves surface durability. Kitchen-grade self-adhesive aluminum foil is preferred for its durability, moisture resistance, and ease of cleaning.

[0023] The adjacent seams of the floor heating-specific reflective film are arranged to ensure flatness; or the adjacent seams of the aluminum foil reflective surface layer are arranged, and the adjacent overlapping seams of the foamed resin base layer are arranged. Although the flatness is worse, it can avoid shielding holes on both sides of the foamed resin base layer without the aluminum foil reflective surface layer, thereby ensuring the complete anti-radiation performance of the wall.

[0024] The self-adhesive wall cloth, self-adhesive wallpaper or self-adhesive flocking cloth are arranged adjacent to each other at the seams, which is convenient for adhesion; or the self-adhesive wall cloth, self-adhesive wallpaper or self-adhesive flocking cloth are arranged adjacent to each other at the seams, which has good flatness.

[0025] Seam covering strips or decorative metal foil strips can be installed at adjacent joints between self-adhesive wall coverings, wallpapers, or flocking sheets on the interior surfaces of common ceilings. Alternatively, seam covering strips or decorative metal foil strips can be installed at adjacent joints between self-adhesive wall coverings, wallpapers, or flocking sheets on the interior surfaces of common interior walls and ceilings. This not only conceals the seams but also prevents heat transfer nodes. Seam covering strips on homogeneous self-adhesive wall coverings, wallpapers, or flocking sheets help prevent visual fatigue.

DETAILED DESCRIPTION

[0032] The method for indoor noise reduction, radiation reduction and strong thermal insulation of the present invention is to adhere a special reflective film for floor heating to the inner surface of a universal indoor wall, or to adhere a foamed resin insulation layer and an aluminum foil reflective layer in sequence, and then cover and adhere a wall cloth or wallpaper or flocking cloth or self-adhesive wall cloth or self-adhesive wallpaper or self-adhesive flocking cloth to achieve noise reduction, radiation reduction and heat insulation on the inner surface of the universal indoor wall; and to cover and adhere a wall cloth or wallpaper or flocking cloth or self-adhesive wall cloth or self-adhesive wallpaper or self-adhesive flocking cloth to the inner surface of the universal roof to achieve heat insulation on the inner surface of the universal roof. The strong thermal insulation is an indoor thermal insulation for strengthening thermal insulation on the basis of the external thermal insulation of the building. Adhering a special reflective film for floor heating can significantly simplify the adhesive installation work compared to adhering a foamed resin insulation layer and an aluminum foil reflective layer in sequence. Self-adhesive adhesives are easier to adhere and install than non-self-adhesive adhesives, and there will be no trouble of brushing glue, pollution, or discoloration during long-term use. Wall cloth and wallpaper offer a highly decorative effect and resist shedding. Wallpaper is easier to clean. Wall cloth offers superior thermal insulation and visual flexibility compared to wallpaper, while flocking offers even better thermal insulation and visual flexibility. The foamed resin insulation layer provides inward insulation and soundproofing, while the aluminum foil reflective layer reflects infrared and electromagnetic radiation. The flocking fabric can be either electrostatic or woven. Specifically, the flocking layer effectively prevents convection heat transfer between indoor airflow and the interior surfaces of the ceiling and walls. This creates a flocking air cushion, effectively isolating indoor air from transferring heat to the flocking layer and from the flocking layer to the indoor airflow. The foamed resin insulation layer, aluminum foil reflective layer, and flocking fabric collectively provide sound insulation, reduce electromagnetic radiation, and provide strong thermal insulation, significantly reducing energy consumption while creating a quiet and comfortable indoor environment. Flocking fabric offers the best thermal insulation. Trial testing has verified that in cold winters in Shandong and Lhasa, indoor spaces employing the indoor noise reduction, radiation reduction, and strong thermal insulation method and its interior decorative layer construction system can maintain temperatures of 16-20°C and 15-18°C, respectively, without heating. In cold winters in Jilin, indoor spaces employing the indoor noise reduction, radiation reduction, and strong thermal insulation method and its interior decorative layer construction system can maintain temperatures of 12-15°C, respectively, with low-intensity heating. In indoor spaces employing the indoor noise reduction, radiation reduction, and strong thermal insulation method and its interior decorative layer construction system, Wi-Fi signals are weakened and radio signals are affected. For example, the signal improves near walls and weakens away from walls, demonstrating a true radiation reduction effect. In the same room, the user who used the indoor noise reduction, radiation reduction, and strong thermal insulation method and its interior decorative layer construction system of the present invention was more likely to fall asleep and sleep deeply, while the user who did not used the indoor noise reduction, radiation reduction, and strong thermal insulation method and its interior decorative layer construction system of the present invention was relatively less likely to fall asleep and sleep deeply. Intuitively, the room with the decoration was much quieter than the one without the decoration, indicating that the noise insulation and noise reduction effect was also significant. Therefore, the multiple functions of noise reduction, radiation reduction, and strong thermal insulation significantly save heating and cooling energy while creating a quiet, healthy, and comfortable indoor environment for people.

[0033] Specifically, the inner surfaces of the walls and the inner surfaces of the ceiling of the bathroom or washroom are covered with a special reflective film for floor heating or a foamed resin insulation layer and an aluminum foil reflective layer to achieve noise reduction, radiation reduction, heat insulation and heat preservation of the inner surfaces of the walls and the inner surfaces of the ceiling of the bathroom or washroom.

[0034] Specifically, the special reflective film for floor heating is composed of a foamed resin base layer and an aluminum foil reflective surface layer narrower than the foamed resin base layer.

[0035] The surface of the special reflective film for floor heating pasted on the inner surface of general indoor walls is covered with self-adhesive wall cloth or self-adhesive wallpaper or self-adhesive flocking cloth, or the adjacent surface of the special reflective film for floor heating pasted on the inner surface of general indoor walls is pasted with a self-adhesive aluminum foil layer covering the foam resin base of the special reflective film for floor heating, and the aluminum foil reflective surface layer and the self-adhesive aluminum foil layer are then covered with self-adhesive wall cloth or self-adhesive wallpaper or self-adhesive flocking cloth.

[0036] The inner surface of the wall and the inner surface of the ceiling of the toilet or bathroom are covered with the special reflective film for floor heating, and the adjacent surface is adhered with a self-adhesive aluminum foil decorative layer covering the foam resin base of the special reflective film for floor heating; or the inner surface of the wall and the inner surface of the ceiling of the toilet or bathroom are covered with the special reflective film for floor heating, and the self-adhesive aluminum foil decorative layer is adhered to the surface.

[0037] The floor heating-specific reflective film is arranged at adjacent seams, which is conducive to ensuring flatness; or the aluminum foil reflective surface layer is arranged at adjacent seams, and the foamed resin base layer is arranged at adjacent overlapping seams.

[0038] The self-adhesive wall cloths or self-adhesive wallpapers or self-adhesive flocking cloths are arranged in adjacent overlapping seams, or the self-adhesive wall cloths or self-adhesive wallpapers or self-adhesive flocking cloths are arranged in adjacent seams.

[0039] Adjacent joints of self-adhesive wall cloth, self-adhesive wallpaper or self-adhesive flocking cloth on the inner surface of a general ceiling are covered with self-adhesive wall cloth, self-adhesive wallpaper or self-adhesive flocking cloth seam covering strips or metal foil decorative strips; or adjacent joints of self-adhesive wall cloth, self-adhesive wallpaper or self-adhesive flocking cloth on the inner surface of a general interior wall and the inner surface of a general ceiling are covered with self-adhesive wall cloth, self-adhesive wallpaper or self-adhesive flocking cloth seam covering strips or metal foil decorative strips.

[0040] Specifically, a foamed resin insulation layer or a special reflective film for floor heating composed of a foamed resin base layer and an aluminum foil reflective surface layer narrower than the foamed resin base layer is bonded to the inner surface of a general indoor wall, the inner surface of a general indoor ceiling, the inner surface of the wall and the inner surface of the ceiling of a toilet or washroom through a spaced foam double-sided tape.

[0041] The distance between adjacent foam double-sided tapes is limited to ensure that the foamed resin insulation layer or the foamed resin base layer of the floor heating special reflective film does not fail to adhere to the inner surface of the wall or the inner surface of the top, and the adjacent surfaces of the spaced foam double-sided tapes are cross-set.

[0042] Specifically, a narrow vertical strip of self-adhesive wall cloth, self-adhesive wallpaper or self-adhesive flocking cloth is first pasted on the inner corner of the wall to achieve flat pasting at the vertical inner corner, and then the wide side of the self-adhesive wall cloth, self-adhesive wallpaper or self-adhesive flocking cloth on the adjacent wall is overlapped and pasted.

[0043] Light-colored self-adhesive wall coverings, wallpaper, or flocking fabrics are applied as a base surface to the interior surfaces of common interior walls and ceilings, respectively. At the junction of the interior walls and ceilings on the base surface, a top inner perimeter strip, top edge strip, or top inner corner strip of the same or darker color as the light-colored self-adhesive wall coverings, wallpaper, or flocking fabric is applied. Alternatively, rigid interior and exterior corner decorative strips are nailed or attached to the junction of the interior walls and ceilings on the base surface and at the interior and exterior corners of the common interior walls. Tonal border strips help reduce visual fatigue, while dark-colored border strips help visually separate the wall and ceiling, enhancing the sense of visual space. Rigid interior and exterior corner decorative strips can enhance the sense of visual space in the room. The ceiling inner perimeter strip can enhance the visual sense of width by outlining the perimeter of the ceiling inner surface. The inner top edge of the wall can enhance the visual sense of wall support by providing an outline. The inner corner trim can enhance the visual sense of ceiling width and wall support by providing an outline, further enhancing the three-dimensional effect of the interior ceiling. Rigid inner and outer corner trims can further enhance the three-dimensional effect of the interior.

[0044] Example 1, as Figure 1As shown, the interior decoration layer construction system for realizing the indoor noise reduction and radiation reduction strong insulation method of the present invention is a general indoor wall inner surface 1 sequentially adhered with a foamed resin insulation layer 21 and an aluminum foil reflective layer 22 and a self-adhesive flocking cloth 3, which can also be wall cloth or wallpaper or flocking cloth or self-adhesive wall cloth or self-adhesive wallpaper, and a general roof inner surface 4 adhered with a self-adhesive flocking cloth 3, which can also be wall cloth or wallpaper or flocking cloth or self-adhesive wall cloth or self-adhesive wallpaper. Compared with non-self-adhesive, self-adhesive is easier to adhere and install, and there is no trouble of brushing glue, pollution, and discoloration during long-term use. The strong insulation is an indoor insulation for strengthening insulation on the basis of the exterior insulation of the building. Wall cloth and wallpaper have good decorative effects and will not shed, wallpaper is easier to clean, wall cloth has better thermal insulation effect and better visual flexibility than wallpaper, and flocking cloth has better thermal insulation effect and better visual flexibility than wall cloth. The foamed resin insulation layer provides inward insulation and soundproofing, while the aluminum foil reflective layer reflects infrared and electromagnetic radiation. The flocking fabric can be either electrostatic or woven. Specifically, the flocking layer effectively prevents convection heat transfer between indoor airflow and the interior surfaces of the ceiling and walls. This creates a flocking air cushion, effectively isolating indoor airflow from transferring heat to the flocking base, or from the flocking base to the indoor airflow. The foamed resin insulation layer, aluminum foil reflective layer, and flocking fabric work together to provide sound insulation, reduce electromagnetic radiation, and provide strong thermal insulation, significantly reducing energy consumption while creating a quiet and comfortable indoor environment. Flocking fabric offers the best thermal insulation. Trial testing has verified that in cold winters in Shandong and Lhasa, indoor spaces employing the indoor noise reduction, radiation reduction, and strong thermal insulation method and its interior decorative layer construction system can maintain temperatures of 16-20°C and 15-18°C, respectively, without heating. In cold winters in Jilin, indoor spaces employing the indoor noise reduction, radiation reduction, and strong thermal insulation method and its interior decorative layer construction system can maintain temperatures of 12-15°C, respectively, with low-intensity heating. In indoor spaces employing the indoor noise reduction, radiation reduction, and strong thermal insulation method and its interior decorative layer construction system, Wi-Fi signals are weakened and radio signals are affected. For example, the signal improves near walls and weakens away from walls, demonstrating a true radiation reduction effect. In the same room, the user who used the indoor noise reduction, radiation reduction, and strong thermal insulation method and its interior decorative layer construction system of the present invention was more likely to fall asleep and sleep deeply, while the user who did not used the indoor noise reduction, radiation reduction, and strong thermal insulation method and its interior decorative layer construction system of the present invention was relatively less likely to fall asleep and sleep deeply. Intuitively, the room with the decoration was much quieter than the one without the decoration, indicating that the noise insulation and noise reduction effect was also significant. Therefore, the multiple functions of noise reduction, radiation reduction, and strong thermal insulation significantly save heating and cooling energy while creating a quiet, healthy, and comfortable indoor environment for people.
