Residential buildings are basically built with reinforced concrete, but the thermal conductivity of reinforced concrete is very large, which means that its thermal insulation performance is not very good. Therefore, during the construction of the house, we also need to add a layer of external wall insulation material inside the wall. It has obvious advantages in hot summer and cold winter areas and hot summer and warm winter areas. This system is suitable for concrete and masonry exterior walls of various multi-story and high-rise new buildings. External insulation can make the building beautiful. As long as the facade design of the building is done well, it will be very good.

Anti-cracking is one of the key technologies to be solved in wall insulation projects, because once the insulation layer and anti-cracking protective layer crack, the performance of the wall insulation project will change greatly, not only failing to meet the energy-saving requirements of the design, but even endangering the safety of the wall. The insulation node design plan is not perfect, forming a local thermal bridge breakpoint; the cutting size of the polystyrene board during construction does not meet the requirements, the rough construction quality causes the gap between the boards to be too large, and no corresponding slat filling treatment is done.

The exterior wall insulation material has good decorative effect, long service life, and many construction plans, which reflects the unique product advantages in the application of prefabricated buildings. It not only realizes the waste of exterior wall decoration and insulation, but also completes the exterior wall insulation decoration integrated board.

In addition to heat preservation, the exterior wall insulation material also has good sound insulation performance. Generally speaking, the materials used in the insulation board have a certain sound absorption ability, which can absorb the external noise, thereby reducing the impact of outdoor noise on the interior and creating a quiet rest environment.
