Advantages of insulation rockwool board

     1. Good water hydrophobicity. Insulation rockwool board has excellent waterproof and vapor barrier properties. The insulation rockwool board does not contain water, and the water absorption rate is very low. It can well block the penetration of water and water vapor, and maintain a good and stable thermal insulation for the wall. This thermal insulation condition is difficult to achieve with other thermal insulation materials at present. There is no joints on the surface of the insulation rockwool board wall and the sealing around the holes and the openings of doors and windows, etc are tight, so that the rock wool board wall has good waterproof performance and avoids the danger of rainwater entering the interior.
     2. There will be no condensation in the wall. Dew condensation inside the wall or inside the thermal insulation layer is harmful. During the drying process of the newly built wall, or in winter, when the water vapor with high indoor temperature migrates to the outside, it is blocked by the insulation rockwool board. So there is no possibility of condensation on the walls. When the indoor humidity is low and the indoor wall is in good condition, the condensation caused by the moisture migration of water vapor in the wall can be avoided.
     3. Can withstand the harshest local climate changes. Extremely hot or cold weather can not cause irreversible damage or deformation on the external wall insulation system. Drastic temperature changes on external wall insulation surface (up to 50 degrees), such as sudden rain showers after prolonged exposure to hot sunshine, or shading after exposure to the sun will not cause damage to the exterior wall surface. So the cracks caused by surface deformation can be avoided.
