Why use Rockwool Dual density insulation boards?

Rockwool not only improves the thermal comfort of buildings, it also helps to reduce noise within the building. Another benefit of Rockwool dual density insulation boards is that they are non-combustible – Non-combustible Rockwool insulation acts like fire barrier and does not contribute to fire. Finally Rockwool is also breathable, making it the insulation material of choice for Architects and builders alike.

Use netting on scaffolding as well as protective rainproof covering to reduce exposure to elements such as rain and excess sunlight.


Rockwool insulation slabs should be installed in accordance with the manufacturer’s instructions – these includes guidelines on design and other aspects of application. We recommend the boards are fixed to the substrate with mortar/adhesive and mechanical fixings to ensure maximum adhesion.

Because of the greater weight of mineral wool we advise that you use the EWI-225 Premium MW Adhesive for the application rather than a standard adhesive, which is used on lighter insulating materials. Apply a light, watery based coat of the adhesive to your prepared surface initially. When it is dry, apply the basecoat, then sink in the fibre glass mesh.


Use an industrial hoover to clean-up the mineral wool fibres.


The Mineral wool comes in packs of 2 sheets in 600mmx1200mm slabs
