Main advantages
Protect the main structure of the building and extend the life of the building. Because external insulation places the insulation layer outside the structure, it reduces the stress caused by structural deformation due to temperature changes and reduces the erosion of the structure by harmful substances in the air and ultraviolet rays.
Effectively eliminate thermal bridges. In the past, internal insulation was used, and thermal bridges were unavoidable. However, external wall insulation can effectively prevent the occurrence of thermal bridges and avoid condensation.
The moisture and temperature situation of the wall has been improved. Generally, internal insulation requires a vapor barrier, but the use of external thermal insulation materials
The temperature permeability is much stronger than that of the main structure, and generally does not occur inside the wall. Due to the condensation phenomenon, the temperature of the entire wall in the structural layer increases, further enhancing the thermal insulation performance of the wall.
It is helpful to maintain a stable room temperature. External wall insulation
is used. Since the structural layer with a large heat storage capacity of the wall is on the inside of the wall, it is helpful to maintain a stable room temperature.
Add the usable area of the house
. It can avoid damage to the insulation layer during secondary decoration.
