Mineral Fibre External Wall Insulation Systems

PermaRock Mineral Fibre external wall insulation (EWI) systems are high-performance thermal insulation systems suited for application onto all building types, including residential buildings, hospitals, hotels,  schools, and multi-storey buildings where the highest levels of fire resistance and non-combustibility are required.

Incorporating non-combustible mineral fibre (stonewool) insulation (Euroclass A1 – BS EN 13501-1:2007 + A1:2009), systems with an A2-s1,d0 classification in accordance with BS EN 13501- 1:2007 +A1:2009 are tested and accredited for use on high rise buildings, including those with floor levels above 18 metres above ground level.

PermaRock Mineral Fibre systems with PermaRock SiliconeUltra K 1.5mm, Brick Slip and Brick Effect Render Finishes are class A2-s1,d0 to BS EN 13501-1:2007 + A1:2009*.
