95mm Knauf Rocksilk Krimpact Flat Roof Slab Extra - pack of 24

95mm Rocksilk Krimpact Flat Roof Extra Slabs are high strength, dense rigid slabs made from rock mineral wool, manufactured using Krimpact technology, specifically designed for use in flat roofing applications. Used for the thermal insulation of flat roofs where a medium level of traffic is required, and hence compressive strength is an issue. Krimpact™ technology realigns the mineral wool fibres during manufacture to increase impact strength without dramatically reducing thermal performance - making an ideal product for use in flat roofs. Furthermore, Krimpact™ technology gives you a consistent density slab. This ensures better long-term compressive strength, high impact resistance, better thermal performance and a thinner, lighter product compared to other high-strength insulation options. These slabs contain a special additive to ensure their water repellency.

Rocksilk Krimpact Flat Roof Extra Slabs are used for the thermal insulation of flat roofs. They are suitable for use under all kinds of single ply membrane, hot applied bitumen systems and mastic asphalt and are suitable for maintenance foot traffic.
