Insulate timber stud walls for thermal and acoustic efficiency

Installing mineral wool insulation inside timber stud walls can help improve acoustic performance and thermal efficiency. Let’s find out how.

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.

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.

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.

Ease of install

Timber stud walls are usually made with studs placed 600mm apart. This means pre-cut mineral wool insulation can be friction-fitted in-between.

Installing stud wall insulation slabs or partition rolls can help to improve thermal performance and minimise the impact of airborne sound transmission.
