120mm Rockwool Flexi Insulation Slab

120mm Rockwool Flexi is a multi-purpose stone wool insulation product engineered to deliver both thermal and acoustic performance. Distinguished by its innovative flexible edge design on one side, this insulation slab ensures superior installation characteristics.

The 120mm Rockwool Flexi slab incorporates patented flexible edge technology, guaranteeing a friction fit between the material and structural framing. Installation is straightforward, with the product fitting easily between fresh timber. As timber naturally shrinks during the drying process, the insulation expands to fill any gaps. Classified as Euroclass A1 non-combustible, 120mm Flexi Slab delivers enhanced thermal and acoustic insulation properties.

Suitable for diverse applications across residential buildings, including pitched roof rafters, timber-framed external walls, and internal partition spaces.
