External Wall Dual Density Slab is a stone wool insulation specifically developed for use in external wall insulation systems.
Made using a ROCKWOOL-patented ‘dual density’ manufacturing process, the top layer of each slab has a distinctly higher density than the remainder of the product.
This provides a robust outer surface for applying render and accepting fixings, while the resilient underside can accommodate unevenness in the substrate.
To aid installation the top layer is branded with ‘THIS SIDE UP’, allowing for quick and easy identification of the outer surface.
