Extruded boards are used for outdoor insulation or metal or plastic wrapping and should be used in places prone to mechanical wear. Attention should be paid to the sealing of joints and joints. If necessary, glue sealing strips should be added, and the overlapping part of the multi-layer should not be less than 100mm. Through this data, we can see that the waterproof characteristics of this material are still very good. Rock wool insulation board has good moisture-proof and waterproof properties, and is particularly suitable for use in rainy and humid environments. Regardless of the construction, it is also backward and there are few types.

The results of thermal insulation and energy saving and the level of construction technology are very unsatisfactory. There are still some problems with the quality of a small number of external wall insulation extruded boards produced. Insulation extruded board manufacturers should be equipped with professional personnel to provide on-site guidance for the construction process, and cooperate with the construction unit and on-site supervision to do a good job in construction quality control. Because this material is divided into insulation type and sound-absorbing and heat-insulating type, it is generally used on the exterior wall. It belongs to the insulation type, and it is sound-absorbing if used indoors, so the choice of type is very critical.

So the quality is relatively inferior. In fact, the rock wool installed on both the exterior and interior walls is the same, and has excellent high and low temperature resistance and durability. It not only solves the cracking problem of wall insulation materials, but also solves the common cracking problem of traditional wall materials.

The correct exterior wall insulation construction steps, after selecting the appropriate accessories, can firmly install the insulation extruded board on the exterior wall. Only in this way can the construction be perfect and can be done once. Density is also the bulk density that people often mention. Too low density will affect the compressive performance of the board and cause the board to soften. If used on the exterior wall, it may cause a headache. The problem is actually "falling off".
