Non-combustible insulation suitable for use in ETICS
ROCKWOOL External Wall DD Slab insulation has been specifically developed for use within external wall insulation systems. Such systems can considerably enhance both the thermal and acoustic performance of a building.
External Wall DD Slab is an insulation product compatible with a wide range of third-party accredited external wall insulation systems.
Manufactured using Dual Density technology, the outer surface of each slab features a distinctly higher density than the underside. This provides a firm and robust surface for the application of fixings and render, while the resilient underside can accommodate unevenness in the substrate.
Once installed, adjacent tightly-butted slabs will effectively 'knit' together to provide a continuous insulating layer, eliminating heat losses that would otherwise be caused by gaps.
Specifying ROCKWOOL insulation within an EWI system gives peace of mind to building owners and tenants alike, safe in the knowledge that stone wool insulation will work as effectively as the day it was installed - even after 55 years of use.
Independently tested acoustic benefits
Water repellent yet breathable, reducing condensation risk
Stone wool is dimensionally stable and will provide the same performance for more than 55 years after installation.
Can be recycled and reprocessed, reducing landfill costs, with zero ODP and GWP.
