The warranty period of the insulation project, sinceAcceptance of completion and destructionCalculated from the date of qualification.

The exterior wall insulation material is fiberglass mesh cloth.

Inorganic active exterior wall insulation materials, silicate.

Thermal insulation materials, ceramic thermal insulation materials, rubber powder, polystyrene particles, steel wire mesh and cement foam boards.

and so on, are common exterior wall insulation materials.

The role of exterior wall insulation:

1. The exterior wall insulation material degree of the exterior wall has a certain protective effect, which can not only protect the temperature difference of the exterior wall main body from changing greatly, but also increase the durability of the exterior wall building and improve the use of longevity potatoes.

2. Exterior wall insulation materials not only have the effect of thermal insulation for the interior, but also improve the indoor environment, so that the indoor will not be damp and mildew, so that we have a dry indoor environment.

3. We install exterior wall insulation materials on the exterior walls, which is not only a low-carbon and environmentally friendly decoration method, but also can effectively avoid the invasion of cold and empty air on the house, which greatly prolongs the life of the house.
