Application

Rocksilk® Flexible Slab is typically used for the thermal and acoustic insulation of a wide variety of constructions such as timber and metal stud partitions, timber frame walls and suspended timber floors. 100 mm Rocksilk® Flexible Slab has been tested to provide up 60 minutes fire protection when a floor is upgraded to a fire resistant floor in line with Approved Document B, for example when a unused loft is converted into habitable accommodation during a loft conversion.

Description

Knauf Insulation Rocksilk® Flexible Slab is a rock mineral wool insulation slab, designed for use in multiple applications providing thermal and acoustic insulation as well as the fire protection of loft conversion floors. It is non-combustible, achieving the best possible Euroclass A1 reaction to fire classification and is manufactured using Knauf Insulation's unique bio-based binder, ECOSE® Technology.
