Help to increase the thermal and acoustic performance of your building

Without insulation, heat can quickly be lost through external walls, but choosing the right insulation layer, such as mineral wool for external wall insulation, can help to improve thermal efficiency .

Take a closer look at the benefits of solid wall masonry insulation

External masonry wall insulation can help to reduce heat loss. Let’s look at the core elements.

Thermal insulation

The small pockets within the mineral wool structure trap air, which is a poor conductor of heat, and significantly reduces heat transfer, making mineral wool an effective thermal insulator. Used as part a system to provide thermal insulation, mineral wool can help to improve thermal efficiency and reduce overall energy costs.

Reaction to fire 

A significant number of our Isover glass mineral wool products achieve Class A1 reaction to fire to BS EN 13501-1, this is the highest level of performance. Please check Declaration of Performance for individual product’s reaction to fire classification.

Ease of install

Due to the tight friction fitting there’s no slumping or need for any additional fixings. Both batts and slabs are designed to be compatible with recommended spacings of external wall applications.

Available in a variety of thicknesses, our solid masonry wall mineral wool insulation can help to improve the thermal, acoustic and fire performance of the structure.
