Knauf offers a helping hand

In response to the current PIR insulation shortage, Knauf Insulation has developed a range of assets, aimed at helping customers easily switch from PIR to a mineral wool alternative, avoiding delays.

The company says that switching insulation specification is not without risk, and so its series of detailed comparison tables for different applications lend a helping hand for those thinking of switching to mineral wool.

For masonry cavity walls, for example, a PIR substitution chart helps users find which thickness of Earthwool DriTherm 32 Ultimate product will achieve the same U-value as the PIR partial fill cavity insulation thickness specified.

Whilst achieving the required U-value will be the priority, the additional benefits of mineral wool insulation may come as a pleasant surprise.

Knauf says the non-combustible material has excellent thermal, acoustic and fire performance characteristics. Friction fitted – accurate installation is also much quicker; and in-situ performance is less likely to be compromised by any gaps or cracks around and behind the insulation, which can significantly affect thermal performance.

Earthwool is manufactured with ECOSE Technology – a revolutionary, no-added formaldehyde bio-based binder technology that reduces embodied energy and delivers superior environmental sustainability.

In addition, Knauf says mineral wool solutions are often the most cost effective option to achieve compliance with Building Regulations.
