ROCKWOOL Flexi is suitable for use in a wide range of applications, including acoustic and thermal insulation for partitions, separating walls and floors, as well as thermal insulation for suspended floors, walls, and roofs.

Flexi® slab has been designed as a multi-use, dual purpose acoustic and thermal stone wool insulation with a unique flexible edge along one side.

The insulation is easy to install and can be fitted between fresh timber and will expand into the wider space as the timber dries out and shrinks back. ROCKWOOL Flexi®  is Euroclass A1 non-combustible as defined in EN 13501-1 and provides additional thermal and acoustic benefits in application.
