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.

External wall insulation materials have a thin paint film during actual application, which can easily freeze and damage latex particles in cold environments. Additionally, due to the low temperature of the film-forming environment, incomplete film-forming can also occur. The thermal conductivity of the insulation board is very low, effectively reducing the thickness of the insulation system and increasing the volume ratio. The main structure has strong adaptability to deformation and good crack resistance and deformation resistance. Polyurethane is a flexible material with large deformation and strong resistance to external deformation.

The external wall insulation material is made from resin containing pentane as raw material. After foaming, the inner beads expand to 3-4mm and 0.5mm, and then age and heat in the mold. Therefore, the insulation board has a micro closed cell structure and can be made in various sizes 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.
