180mm Rockwool Flexi Insulation Slab

180mm Rockwool Flexi represents a high-performance stone wool insulation product engineered to deliver both thermal and acoustic performance. Distinguished by its patented flexible edge design on one side, this product offers superior installation characteristics.

The 180mm Rockwool Flexi slab incorporates a proprietary flexible edge mechanism that creates a secure friction fit between the material and structural framing. Installation is straightforward, with the insulation positioned between fresh timber members. As timber naturally dries and shrinks, the 180mm Flexi Slab expands to maintain complete coverage. This product achieves Euroclass A1 non-combustible status, delivering enhanced thermal and acoustic insulation performance.

The material performs effectively across multiple building applications, including pitched roof installations, timber-framed external walls, and internal partitions.
