In the exterior wall insulation material system, the thermal bridge effect of the fixings and supports should be fully considered. Secondly, waterproofing should be done well to ensure that water does not accidentally enter the insulation layer and base layer. The horizontal or inclined selected parts and the parts extending below the air should be waterproofed.

After the protective layer is completed, it is necessary to regularly sprinkle water for maintenance according to the weather conditions to prevent the moisture from drying too quickly and causing surface cracking. Because there is sun, maintenance will start the next day. Insulation construction is carried out. The left and right sides of the insulation layer are heat insulation to prevent the indoor temperature under the terrace from overheating in summer and overcooling in winter.

The exterior wall insulation integrated board has many incomparable advantages in installation and construction compared with traditional insulation materials. Let's analyze it in detail together. Traditional insulation materials, insulation and decorative layers are classified from each other. Users purchase from different manufacturers and units construct on site.

The insulation effect of fully enclosed external wall insulation materials is not outstanding. On the contrary, materials with larger porosity can isolate air with their own pores, reduce thermal conductivity, and have better insulation effect. The advantages and disadvantages of insulation materials, two of which are important indicators are thermal conductivity and hydrophobicity. Because of the thickness limit of polyurethane insulation board, in order to prevent water seepage at the window position (especially flat window) during construction, other materials need to be used instead. The exterior wall polyurethane insulation board is greatly affected by ultraviolet rays and temperature.

It meets the fire protection requirements of building exterior walls, which will promote the replacement of traditional EPS boards with highly flame-retardant SEPS insulation boards and promote the structural adjustment of the building insulation material market. Due to the improvement of insulation capacity, the demand for organic raw materials such as polystyrene for graphite polystyrene insulation boards will decline, thereby reducing environmental pollution.
