After the actual application and construction of the roof and exterior wall insulation material, the surface should be flat and must be smooth to prevent water seepage and moisture absorption on the roof. If the laid insulation board is loose and the insulation board is in a board shape, the human body cannot continue to walk on the insulation board. If walking is required, scaffolding should be laid on the surface of the insulation board.

When the external wall insulation material is applied thinly during the actual painting process, it is easy to freeze in cold environments, and due to the low ambient temperature, this can easily cause damage to the wall construction. If the actual thermal conductivity of the external wall insulation material is low, it can effectively reduce the thickness of the insulation system, increase the volume ratio, and have strong adaptability to deformation of the main structure, and the crack resistance and deformation resistance will also become better.

External wall insulation materials containing pentane resin, in practical applications, when foaming occurs, the inner beads will expand to 3-4mm with a thickness of 0.5mm, and then the insulation material will age and heat up. Therefore, external wall insulation materials have a micro closed cell structure, and in practical applications, various sizes can be made according to user requirements. For some houses in coastal areas, the strength of the roof is very important. Moreover, during the installation process, further reinforcement and auxiliary fixation are required after the installation is completed.

In summer, the application of external wall insulation materials can reduce the entry of sunlight, thereby lowering the temperature of walls and indoor air. Due to the unchangeable climate, the temperature of the wall inside the insulation layer changes significantly, causing the temperature of the wall to rise and fall, with a relatively gentle temperature change and reduced thermal stress.
