Description

[0001] POLYISOCYANURATE WALL THERMAL INSULATION SYSTEM

[0002] Technical Field

[0003] The invention relates to a wall thermal insulation system that provides durability, thermal insulation and superior fire resistance performance on building exteriors.

[0004] In particular, the invention relates to an impact-resistant, long-lasting polyisocyanurate wall thermal insulation system that provides high thermal resistance and unique energy efficiency with low thermal conductivity (lambda) value material content in the walls and partitions of buildings made of light section steel.

[0005] State of the art

[0006] The decrease in available primary energy resources in the world necessitates the effective and efficient use of these resources. The concept of thermal insulation and the thermal insulation levels that buildings should have have also gained importance at this point. Thermal insulation is important not only for energy saving but also for preventing environmental pollution and providing thermal comfort.

[0007] In the state of the art, XPS (Extruded Polystyrene Foam), Rockwool, EPS (expanded polystyrene rigid foam) are used as thermal insulation material on brick or similar material in exterior thermal insulation applications. Thermal insulation performance of insulation materials is measured by their thermal conductivity (lambda value). The lower the thermal conductivity value, the less the insulation material conducts heat and the better the thermal insulation. Thermal conductivity (lambda value) values of the materials available in the technique are high, but their efficiency is low. Lambda value, also shown as "K" value or "A" value", is the expression in Watts (W) of the heat flow occurring in a 1 m thick material with a surface of 1 m2, when the temperature difference between the inner and outer surfaces is 1 Kelvin. The thermal conductivity of products is measured in W / mK units. The lower the Lambda value, the higher the thermal conductivity resistance of that product will be. In addition, since these materials are insufficient in terms of point load, they can be easily punctured and shattered. For this reason, light steel applications require the use of betopan (precast concrete panel) or similar materials on the outer surface. For this reason, new products that provide high thermal resistance with low thermal conductivity value in the known state of the art and do not require the use of additional materials with the feature of being resistant to impacts in terms of point pressure are needed.

[0008] In the research conducted in the literature, document numbered 2019 / 17797 can be shown as an example to the state of the art. The said document relates to a thermal insulation board, which is used in the sheathing process of buildings in the construction industry and provides heat, sound, water and moisture insulation. Said product comprises rock wool-glass wool in sheet form and EPS styrofoam in sheet form coated on both surfaces of said rock wool-glass wool. However, the wall thermal insulation system made of Polyisocyanurate material is not mentioned.

[0009] As a result of the aforementioned issues and the limited supply of available solutions, it became necessary to carry out an improvement in the relevant technical field.

[0010] Object of the Invention

[0011] The present invention relates to a thermal insulation system which eliminates the abovementioned disadvantages and brings new advantages to the relevant technical field.

[0012] The main object of the invention is to provide an insulation system with high thermal efficiency with the content of Polyisocyanurate (PIR) board, which provides higher thermal resistance compared to other insulation materials due to its low thermal conductivity (lambda) value.

[0013] The object of the invention is to provide a product that is resistant to impacts against materials that are easily punctured / shattered in the current technique in terms of point load.

[0014] An object of the invention is to provide a thermal insulation system that provides high energy efficiency.

[0015] Another object of the invention is to provide a product with high fire safety. Another object of the invention is to provide a long-lasting insulation system as well as increased durability.

[0016] In order to fulfil the above-mentioned purposes, the invention is a thermal insulation system with increased fire and impact resistance and high thermal resistance to be applied on the walls and partitions of the building, comprising a PIR board between the steel profiles and providing thermal insulation, Kraft paper on two surfaces of the PIR board and a ceramic primer layer which increases the number of surface friction layers by applying on the kraft paper on the outer surface of the PIR board.

[0034] Detailed Description of the Invention

[0035] In this detailed description, the preferred embodiments of the product of the present invention are described only for clarifying the subject matter in a manner such that no limiting effect is created.

[0036] The invention relates to a thermal insulation system with increased fire and impact resistance and high thermal resistance to be used on building walls, especially in the walls and partitions of buildings made of light steel profiles. Said thermal insulation system comprises the following in its most basic form; PIR board (1 ) providing thermal insulation, Kraft paper (2) on both surfaces of the PIR board (1 ) and a ceramic primer layer (3) that increases the surface friction coefficient by applying on the kraft paper (2) on the outer surface of the PIR board (1 ).

[0037] Polyisocyanurate (PIR) is a compound formed as a result of the chemical reaction between PMDI (polymeric methyl diphenyl isocyanate) or MDI and polyol. The amount of MDI and flame retardant catalyst used in PIR production is higher. It consists of isocyanurate chains, which have higher chemical stability at high temperatures. Compared to polyurethane, its flammability and smoke formation are much lower. It provides superior thermal insulation due to its closed cell structure. Panels made of polyisocyanurate material resist the spread of flames during fire and reduce the radiant heat that may cause flammability and the gases emitted during combustion are less toxic than the gases emitted by conventional building materials. In addition, panels / boards made of this material are not in danger of causing after fires. In the event of a possible fire, it does not contribute to the fire; only the panels / boards around the area where the fire broke out are damaged and when the flame load is eliminated, they extinguish themselves.

[0038] The thermal insulation system of the invention also includes a thermal insulation system render layer (4), which is applied on the said ceramic primer layer (3) and provides resistance against impacts on the external wall. In addition, the system includes a mineral-based decorative render layer (6) that is applied on the thermal insulation system render layer (4) and provides a decorative appearance on the exterior, and an exterior paint layer (7) that gives its color to the exterior wall.

[0039] In a preferred embodiment of the thermal insulation system of the invention, the thermal insulation system render layers (4) applied on the ceramic primer layer (3) and providing resistance against impacts on the outer wall, and the mesh application (5) increasing adhesion to the surface between the said thermal insulation system render layers (4). Said thermal insulation system includes a mineral-based decorative render layer (6) that is applied on the thermal insulation system render layer (4) and provides a decorative appearance on the exterior, and an exterior paint layer (7) that gives its color to the exterior wall.

[0040] The thermal insulation system of the invention also includes a plasterboard layer (8) applied on the kraft paper (2) on the inner surface of the PIR board (1 ) and providing strength on the interior walls. The system additionally includes a satin plaster layer (9) to close the joint gaps at the joints of the said plasterboard layer (8). It consists of a paint conversion primer layer (10) that is applied on the said satin plaster layer (9) and ensures that the paint adheres to the surface, and an inner surface paint layer (1 1 ) that gives its color to the inner wall.

[0041] Said thermal insulation system render layer (4) increases the insulation performance of the wall and its resistance to external impacts and improves its cosmetic appearance.

[0042] Said Ceramic primer layer (3) increases the friction coefficient of the surface and ensures that an external plaster to be applied adheres to the kraft paper (2) on the PIR board (1 ) surface.

[0043] An application of a thermal insulation system according to the invention comprises, from the inner surface of the wall to the outer surface, an inner surface paint layer (11 ), a paint conversion primer layer (10), a satin plaster layer (9), a plasterboard layer (8), Kraft paper (2), PIR board (1 ), Kraft paper (2), a ceramic primer layer (3), a thermal insulation system render layer (4), a mineral-based decorative render layer (6) and an exterior paint layer (7). A preferred embodiment of a thermal insulation system according to the invention; from the inner surface of the wall to the outer surface, respectively, the inner surface paint layer (11 ), paint conversion primer layer (10), satin plaster layer (9), plasterboard layer (8), Kraft paper (2), PIR board (1 ), Kraft paper (2), ceramic primer layer (3), thermal insulation system render layer (4), mesh application (5), thermal insulation system render layer (4), mineral based decorative render layer (6) and exterior (outer surface) paint layer (7). Figures 1 and 2 show the preferred application of the thermal insulation system subject to the invention on external and internal surfaces.

[0044] An embodiment of the system subject to the invention is as follows; PIR board (1 ) material is cut to the desired dimensions and placed between light steel profiles. There is kraft paper (2) on two surfaces of the PIR board (1 ) (inner and outer surfaces) that ensures the smoothness of the surface. Since the necessary adherence cannot be achieved when plaster is applied directly on the kraft paper (2) on the outer surface of the PIR board (1 ), the friction coefficient of the surface is increased by applying a ceramic primer layer (3). In this way, proper adhesion of a thermal insulation system render layer (4) to be applied to the kraft paper (2) on the surface of the PIR board (1 ) is ensured. Then, a mineral-based decorative render layer (6) is applied on the exterior of the building to provide the desired visual appearance suitable for the walls. Finally, an exterior paint layer (7) in the requested color is applied to the outer wall. In the interior of the building, a plasterboard layer (8) is applied on the kraft paper (2) on the inner surface of the PIR board (1 ) in order to provide the necessary strength and create a paintable wall. The joint gaps are closed by applying a satin plaster layer (9) to the joints of the plasterboard layer (8). Afterwards, a paint conversion primer layer (10) is applied to ensure that the paint adheres to the surface. The system is completed by applying inner surface paint layer (11 ) in the desired color to the interior wall.
