Rocksilk Krimpact Flat Roof Slab
For the thermal
insulation of flat roofs where a medium level of traffic is
required, and hence compressive strength is an issue.
Description
A range of high strength, consistent density, rigid slabs made
from rock mineral wool, manufactured using Krimpact™
technology, specifically designed for use in flat roofing.
The Rocksilk Krimpact Flat Roof Slab product range includes two
slab densities:
- Rocksilk Krimpact Flat Roof Slab
- Rocksilk Krimpact Flat Roof Slab Extra
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.
Application

of flat roofs. Rocksilk Krimpact Flat Roof Slabs are suitable for
use under all kinds of single ply membrane, hot applied bitumen

- Rocksilk Krimpact Flat Roof Slab has high compressive strength,
where some occasional loading and impact resistance is
required.
- Rocksilk Krimpact Flat Roof Slab Extra is for use where optimum
long term compression performance is required.
Thermal Peformance
Rocksilk Krimpact Flat Roof Slabs have thermal conductivities of
0.038 to 0.039 W/mK
