Product Information

Rockwool Flexi is a multi-use, dual purpose thermal and acoustic insulation slab with a unique flexible edge along one side. The flexible edge ensures a perfect fit is maintained between the product and its supporting framework for optimum effectiveness. Rockwool Flexi provides effective thermal insulation, fire resistance and acoustic performance in all framed areas of the building. The flexi edge allows the product to be tightly fitted between timber and metal frames, without the need for cutting or waste.

Key Features

  • Patented flexi edge offers accurate fit to all widths
  • Will not slump, even if studs shrink
  • Fits all typical metal and timber frame spacing
  • Excellent thermal, acoustic and fire properties
  • Non-combustible (Euroclass A1)
  • Easy to handle and install
  • Superior fit with no waste

Standards
Rockwool Flexi has a thermal conductivity of 50-120mm, 0.038 W/mK when tested to EN13162. At 140 mm thickness, Rockwool Flexi has a thermal conductivity of 0.035W/mK. Rockwool Flexi works in two distinct ways to reduce noise, either by impeding the transmission of sound through an element of the structure, or by absorption of sound at the surface. Noise absorption is expressed as a factor between 0 and 1.0. The more sound that a surface absorbs, the higher its absorption coefficient is. The structure of the fibres in Rockwool Flexi slabs make them ideal for use as a sound absorber, with characteristically high coefficients over a wide frequency range. Rockwool Flexi corresponds to the BRE Global Green Guide online generic specification Stone wool insulation-density 45 kg/m³ which achieves a summary rating of A+ within all building types. All Rockwool stone wool insulation repels liquid water due to its fibre orientation and the presence of water repellent additives. Relying on entrapped air for its thermal properties, Rockwool Flexi does not contain gases that have an ozone or global warming potential. Therefore, they have a zero GWP for the purposes of rating schemes such as the Code for Sustainable Homes.
