Wall board is a glass wool board which has water repellent properties owing to the fact that it contains silicone. It is used in between two walls, at double layer sandwich wall panels for fire safe thermal and sound insulation purposes.
Wall Board is applied loose in between two wall components such as bricks, AAC blocks, concrete blocks at the facades. In this application, known as sandwich wall insulation, two wall components should be connected to each other with special fasteners at certain intervals. Owing to their water repellent properties, the boards do not allow any water leakage which might occur as a result of any damage on the facade cladding of the building. By this way, they remain dry and keep their insulation properties. Additionally, even in the case of condensation they allow insulation properties to be maintained by throwing the condensed water out quickly.
