Rockwool – HARDROCK® Multi-Fix (DD)
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.
Versatile Rockwool Insulation
While often used in external walls Rockwool slab insulation can be installed just about anywhere you might otherwise install fibreglass batts. That includes ceilings, lofts, cavity walls and elsewhere.
Because it is denser than fibreglass, Rockwool insulation exhibits better fire resistance and is capable of withstanding high temperatures for extended periods of time. That density also gives Rockwool its outstanding acoustic insulation properties while its mineral composition enables it to repel water.
Hardrock® Multi-Fix Dual Density insulation is semi-rigid so it can be easily fashioned to effectively dovetail with virtually every type of space. Should moisture intrude into the space the Rockwool will not absorb it, but rather repel it and allow it to evaporate.
Price vs Value
Rockwool Dual Density Slab insulation is slightly more expensive than fibreglass batts. It’s true. But its higher R-value, moisture resistance, and ability to retain its shape over the years means additional savings that should more than offset the higher initial expenditure. In other words, it’s a better long term value than fibreglass.
