Exterior wall insulation materials refer to a type of thermal insulation technical materials used for building structure walls. According to the location information used by students, it can be divided into: exterior wall insulation materials, interior wall insulation materials, and roof insulation materials. The exterior wall insulation decorative integrated board has high pressure and tensile strength, which allows it to withstand higher pressure during use, is not easy to deform, and maintains its properties for a long time. Under the same thermal insulation requirements, the thickness of the main structure of the engineering building can be reduced.

If the surface of the polystyrene board joints is uneven during the exterior wall insulation material project, you can choose to use coarse sandpaper lined with wooden squares to lightly sand it in the circumferential direction, and then use a brush to clean up the debris on the surface. Unlike extruded boards, which are made of polystyrene, rock wool boards are made of high-temperature hot-melt basalt. Its advantage is that it is fire-resistant and has better fire-proof performance, but its thermal conductivity is higher than that of extruded board, so its thermal insulation performance is not as good as that of extruded board.

Its efficacy is becoming increasingly prominent, its decorative materials are green and environmentally friendly, and its installation effect is unique. Many office buildings and residential communities favor this new type of insulation material when carrying out wall insulation construction.

When working with exterior wall insulation materials, the ambient temperature should not be lower than 5°C, the wind force should not be greater than Level 5, and the wind speed should not be greater than 10m/s. Construction on rainy days is strictly prohibited. Except for the use of cast-in-situ concrete exterior wall external insulation systems, the construction of external insulation projects should be carried out after the base construction quality has been accepted. This step is very important if you want the insulation layer to be good. During the preparation process, you should stir while adding water, and then use a handheld electric mixer to stir for about five minutes. If the stirring is uneven, you can add more time until the consistency is moderate.
