Friction-fit mineral wool insulation for steel-frame walls

Steel frame construction is used in many commercial and residential projects. Mineral wool can be used as the insulation inside the steel frames to improve the thermal performance, acoustic properties and reaction to fire performance of the structure.

Take a closer look at the benefits of steel-frame wall insulation

When constructing external steel-frame walls, there are lots of benefits to using mineral wool insulation products, from thermal resistance to acoustic benefits. 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 

AA 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.

Acoustic performance

The non-continuous structure of the glass fibres that make up glass mineral wool impede the passage of sound. This can be used in systems to reduce airborne sound transmission and improve acoustic insulation when installed in accordance with the manufacturer’s system installation guidance. For our system information, please refer to the British Gypsum White Book specification selector.

Available in a variety of thicknesses, our external steel-frame insulation can help t o improve the thermal, acoustic and fire performance of the wall.
