Pay attention to the influence of weather factors when constructing extruded boards. In principle, construction is allowed when the humidity is relatively low. If the air humidity is too high, it is required to apply interface agent or similar products on the base layer. The technical nature of the exterior wall extruded board is to assemble multiple protective layers to ensure the actual effect of insulation. Generally speaking, there are three protective layers, insulation layer, anti-seepage protective layer and anti-crack fiber protective layer.

For the extruded board to exert its excellent performance, you must choose a suitable storage environment. In an environment where the package is not opened, the shelf life of the extruded board is about six months, and its shelf life is about three months during the rainy season. Due to the special structure of the XPS board, its compressive strength is very high. It has strong impact resistance. According to the different models and thicknesses of XPS, the compressive strength reaches 150~500Kpa or more, which can withstand the ground load of each system and is widely used in geothermal projects.

The extruded board is made by extrusion process. Effective control of this link can achieve quality control of the board. It is conducive to the design of the building appearance. Create a continuous and non-interrupted cladding structure for the exterior wall of the building envelope, giving the wall a high thermal resistance value, so that the building achieves excellent low energy consumption, that is, energy-saving effect.

According to the requirements of the drawings, first draw the horizontal line of the water dispersion along the elevation of the exterior wall; if the system deformation joint needs to be set, the deformation joint line and the deformation joint width line should be drawn on the wall. The environmental performance of XPS board mainly depends on weather factors. At present, most manufacturers use CO2 as a catalyst, but some manufacturers have been using Freon. According to the inspection of relevant national departments, the chemical performance is stable and does not produce any industrial pollution.
