Waterproofing and insulation for roofs are particularly important in construction. Roof-specific rock wool boards have excellent compressive strength and point load resistance, capable of meeting the weight requirements for construction and maintenance on the roof, as well as the weight of related equipment. There is no need for a separating layer between the waterproofing layer and the rock wool insulation layer, and they are compatible with various waterproofing membranes.
