Wall Insulation

Wall Insulation

We provide a range of wall insulation solutions for both internal and external walls delivering thermal, sound and fire protection.

Our insulation solutions for external wall systems cover rainscreens, overcladding, external façades, masonry cavity walls, and wood and metal frame constructions.

We also have a full portfolio for internal and separating wall insulation solutions, which prevent the transfer of noise from room to room, act as a fire barrier and deliver thermal performance.

Understanding Vapor Diffusion

Vapor diffusion is the movement of water vapor molecules though porous materials as a result of vapor pressure differences.

FAQ's

What is the difference between ROXUL SAFE’n’SOUND® and COMFORTBATT®?

ROXUL SAFE’n’SOUND® is designed specifically for sound attenuation. The density and thickness of the product is optimised for acoustical performance. SAFE’n’SOUND® is not branded with an R value as it’s typically used in interior partition walls that do not require an R value. Therefore, SAFE’n’SOUND® would not pass an inspection if used in an exterior wall. 

ROXUL COMFORTBATT® is used in exterior walls and so the quality control performed on the product is done to meet the standards required per R value labelling. It is also branded with an R value and so would pass a home inspection so long as the R value as per the building code is met. Like all our products, ROXUL COMFORTBATT® is made out of mineral wool and therefore offers some acoustical performance.

What fastener would I use with ROXUL COMFORTBOARD®?

The fastener type used should be appropriate to the substrate [concrete wall, wood stud, etc.] Please refer to the fastener guideline document found on our website. 

Can glue or an adhesive be used to attach ROXUL COMFORTBOARD®?

You can use a construction grade glue/adhesive to temporarily attach the insulation in a situation where the stud wall is being built on top/after the insulation. In this case, the stud wall would hold the insulation in place. We do not recommend permanently attaching the insulation using glue as this may cause the insulation to peel/fall off once the glue dries.

May I still use ROXUL SAFE’n’SOUND® in an exterior wall?

Yes, you can but if inspected, would not pass the inspection as a product with a labelled R value is required.

Superior acoustic performance

ROCKWOOL stone wool products are amongst the most effective acoustic insulation solutions used in construction.

Unmatched fire resistance

Applying ROCKWOOL insulation adds an important layer of fire protection and thereby significantly enhances the fire safety.
