Rock wool board insulation, why add two layers of glass fiber network, and XPS is a layer?
Rock wool with two layers of mesh cloth and not improve crack resistance, but because wool soft texture, installing the anchor bolt after the surface is uneven, with two layers of mesh is to increase the thickness of the mortar, to find the plane. There is no such phenomenon in the extrusion board.
Yes, that's right. Do two layers of mesh cloth to increase the thickness of the surface layer, improve the anti cracking performance and prevent the rainwater from seeping in. We are now doing a rock wool insulation is done: rock wool board full sticky paste, wire mesh hanging in the 50*50 rock wool board, and fixed with anchor bolt, with glazed hollow bead insulation mortar leveling (20mm thick) coated on the surface of the mortar, the middle laying a layer of mesh cloth. The advantage of this method is that the surface smoothness is good, and the anti cracking effect is good. It can prevent the rainwater from entering and make the rock wool soak.
