In our daily buildings, in order to achieve good thermal insulation of the roof, extruded boards are often used as roof insulation materials. Extruded boards are very lightweight, highly viscous, very simple to operate, and easy to cut during transportation. Extruded boards are light in weight, good in performance, and stable in structure.
And because extruded boards have continuous extrusion with independent bubble structure, the density, water absorption, thermal conductivity and air permeability of the board are very good. Why can extruded boards gain great attention and practicality? This is inseparable from their own material.
First, the material of extruded boards is mainly polystyrene, with foam as the main raw material, manufactured by adding high-quality flame retardants, hence called high-temperature extruded rigid foam board, xps extruded board, xps foam board, xps board, xps insulation board. As a new generation of building insulation material, the hard surface of extruded board is very uniform, and the internal insulation material is a continuous and uniform honeycomb structure.
Second, the compressive strength and thermal insulation effect of extruded boards have better water vapor permeability than other insulation material polystyrene eps foam, so the thermal insulation function is very excellent. As a building material, the first compressive ability must be used, and the compressive performance of extruded boards is very strong. Even when soaked in water, the compression and thermal insulation functions are almost the same, which is an effect that other insulation materials cannot achieve. This is also a major advantage of roof insulation and roof building materials. Due to its excellent corrosion resistance and aging resistance, it can maintain a strong thermal insulation function even in extremely humid environments, and it generally has a service life of up to 30-40 years. The service life of roof insulation materials is outstanding, which is also one of its huge advantages.
During construction, extruded boards with low thermal conductivity can be used to wrap the entire building, stabilizing the cold and warm environment inside the building. It not only prevents thermal bridge condensation, but also eliminates heat loss caused by thermal bridges, which can greatly improve energy utilization efficiency and save energy. As a house protection structure, extruded boards can also extend the service life of buildings. External insulation can effectively prevent damage to building structures, buffer structural deformation stress caused by temperature changes, reduce erosion of harmful gases in the air and UV radiation on the structural envelope, reduce the possibility of wall cracking, and extend the service life of buildings.
Third, waterproof effect. Anti-aging property allows it to maintain a strong thermal insulation function even under high water vapor pressure, and its service life can also reach 30-40 years. The service life of roof insulation materials is very outstanding. In bad weather, walls are damp, and the low water absorption of extruded boards is conducive to maintaining the anti-aging of the house. In addition, external wall insulation design does not require installing an air insulation layer. On the one hand, it can effectively prevent rainwater and moisture outside the insulation layer, reducing house humidity. On the other hand, it can extend service life and is safe and reliable. The building's insulation system makes the entire insulation system more reliable through the insulation, pasting and bolt fixing of the extruded board external wall (different from the fixing method of pasting and external metal mesh). The external wall insulation does not consider the internal decoration cycle. After construction, construction may be particularly suitable for high-rise buildings. In addition, extruded board external wall insulation has the advantages of convenient construction and increased use of house area.
In summary, extruded boards can be used as commonly used insulation materials in building materials, and their advantages are very beneficial when considering factors and fields of house construction and external wall insulation.
