[0002] With the increasing requirements for energy conservation and environmental protection, the performance requirements for doors and windows in the construction field are getting higher and higher. In the existing technology, many doors and windows still have deficiencies in air tightness, heat insulation and water tightness. Especially in the face of extreme climatic conditions, traditional windows cannot effectively isolate the influence of the external environment, resulting in energy waste and reduced indoor comfort. Although the existing airtight windows can provide a certain sealing effect, the sealing performance is easy to decline in long-term use, affecting the service life. Summary of the invention

[0003] In order to solve the above problems, the present invention provides an airtight exterior door and window. By adopting innovative technologies such as low-emissivity (Low-E) glass, triple-glazed design, inert gas filling, and double-layer sealing system, the thermal isolation and airtightness of the door and window are improved, and the door and window have better wind pressure resistance and water seepage resistance.

[0004] To achieve the above object, the technical solution of the present invention is as follows: An airtight exterior door and window comprises a window frame, a glass unit, a sealing system, and a connecting assembly. The glass unit comprises three layers of glass, the glass divides the glass unit into two chambers, the chambers are filled with inert gas, the three layers of glass are Low-E glass, clear glass, and Low-E glass from inside to outside, the window frame is connected to the glass unit, the sealing system is arranged on the inner side of the window frame, the connecting assembly comprises a hinge, a lock, and an adjusting bolt, the hinge is connected to the glass unit and the window frame, the lock is arranged on the window frame, and the adjusting bolt is used to fix the sealing system.

[0005] As an improvement of the present invention, the sealing system is a double-layer sealing strip, the outer layer of the double-layer sealing strip is weather-resistant rubber or EPDM, and the inner layer is silicone.

[0006] As an improvement of the present invention, the window frame is a thermal bridge aluminum alloy window frame, the window frame is provided with at least one hollow cavity, and the hollow cavity is filled with polyurethane foam or expanded polystyrene (EPS) material.

[0007] As an improvement of the present invention, the Low-E glass includes a base glass and a coating, and the coating is any one or two of silver oxide, indium oxide, indium tin oxide, titanium oxide, magnesium fluoride, and aluminum fluoride.

[0008] As an improvement of the present invention, the inert gas in the chamber is argon, the base glass is float glass, and both sides of the base glass are coated with coatings.

[0009] As an improvement of the present invention, the heat transfer coefficient of the Low-E glass is not greater than 1.4 W / (m 2 ·K), the shading coefficient of Low-E glass shall not be less than 0.6.

[0010] As an improvement of the present invention, sunshade shutters are also arranged on the inner side of the window frame.

[0011] The present invention also provides a method for installing the above-mentioned airtight exterior door and window, comprising the following steps: S1. Pre-embed the energy-saving auxiliary frame in the reserved hole of the building wall. The energy-saving auxiliary frame should be firmly fixed to the wall, and its depth should be consistent with the installation depth of the window frame to ensure that the outer side of the external door and window is flush with the outer wall; S2. Place the window frame in the energy-saving auxiliary frame, ensure that the window frame is horizontal and vertical, and use bolts to fix each corner of the window frame and auxiliary frame, with the bolt spacing not exceeding 300mm; S3. Use weather-resistant sealant to fill the gap between the window frame and the wall, ensuring that the gap width is between 10-20mm and the gap depth is 20mm. The sealant should be filled evenly and continuously; S4. Lay a waterproof vapor-permeable membrane at the junction of the outer side of the exterior doors and windows and the exterior wall.

[0013] The beneficial effects of the present invention are: The present invention adopts a three-layer glass structure, in which two layers of Low-E glass and the inert gas (such as argon) filled in the inner cavity effectively prevent the transfer of heat and significantly reduce the thermal bridge effect. The window frame is provided with a hollow cavity and filled with polyurethane foam or expanded polystyrene (EPS) material, which further improves the thermal insulation performance of the window and reduces energy loss. This makes the indoor temperature more stable, saves energy consumption for air conditioning and heating, and meets the needs of modern energy-saving buildings.

[0014] The window frame design of the present invention uses thermal bridge aluminum alloy material to effectively prevent heat conduction and improve the weather resistance and structural strength of the window. At the same time, the window is equipped with a waterproof vapor-permeable membrane and a waterproof vapor-blocking membrane overlap design to prevent moisture penetration and condensation, keep the inside of the window dry, and avoid material aging or window damage caused by water vapor. This application uses a double-layer sealing strip (the outer layer is weather-resistant rubber or EPDM, and the inner layer is silicone) combined with a high-precision installation method to ensure that there is no gas leakage between the window frame and the wall. The good sealing of the window effectively isolates outdoor noise and dust, significantly improving the comfort and quiet environment of the room.

[0015] The airtight exterior door and window provided by the present invention can maintain good airtightness and heat insulation during long-term use, has a long service life and a long maintenance cycle, and effectively reduces maintenance costs and energy losses during use.
