The most commonly used insulation material in buildings now is the exterior wall decoration insulation board. As a new type of material, it has been loved by consumers for its integrated effect of insulation and decoration. However, when purchasing exterior wall decoration insulation boards, it is necessary to master certain strategies and skills in order to choose good products.
1. The first thing to pay attention to when purchasing exterior wall decorative insulation boards is of course their thermal insulation characteristics. The insulation characteristics are influenced by the raw materials used in the insulation layer. Generally, organic thermal insulation materials (such as EPS, XPS, polyurethane, phenolic foam, etc.) have better thermal insulation effect than inorganic thermal insulation materials (such as rock wool insulation board, glass fiber wool, inorganic, cement foam, etc.).
2. Before purchasing, carefully check the appearance of the exterior wall insulation and decoration integrated panel. Choose those with minimal damage, uniform color, and consistent size.
3. Calculate the density of the product during the process of purchasing exterior wall decorative insulation boards. By selecting a small sample and weighing it, and then measuring its volume, its density can be calculated. Generally speaking, the higher the density, the better the product. Test the strength of the product. The strength requirements for exterior wall insulation and decoration integrated panels, insulation and decoration panels, etc. are to meet the needs of transportation during construction, and there should be no breakage.
4. At the end of the purchase, it is important to check that qualified and legitimate insulation and decoration materials have quality and technical testing reports or certificates.
5. You need to be particularly careful when making a purchase last time. Otherwise, in future purchases, you may think that the previous purchase was correct, which may lead to your next purchase
