Rockwool Flexi Insulation Slab

The perfect friction fit for framed constructions Rockwool Flexi Insulation Slab is a unique, flexible-edged insulation product, specifically developed using patented technology for a fast and easy, perfect friction fit between timber and metal frame systems.

Rockwool Flexi

Flexi insulation slabs ensure essential tight fitting for thermal and acoustic integrity between frames in walls, partitions, floors and roofs, without the need for cutting or waste. 
Made from renewable volcanic rock, they are extremely fire resistant and significantly reduce the carbon footprint of a building.

Advantages

  • Outstanding thermal, acoustic and fire properties 
  • Rockwool Flexi Insulation edge offers accurate fit to all widths
  • Multi-application; fits all typical metal and timber stud spacing
  • A wide range of thicknesses
  • No waste
  • Easy to handle and install without gaps
  • Fire classification A1
  • Can be used as a full fill solution in timber-frame party walls to achieve zero effective U-value within SAP 2012.

Product properties and design

Rockwool Flexi suits standard stud and floor joist spacings and is available in the following sized slabs: 50mm 70mm and 100mm.

Packaging

Rockwool Flexi Insulation is supplied palletised, compression packed in polyethene bags, protected by a weatherproof covering it can be stored outside. However, the Flexi slabs should not be left permanently exposed to the elements.

Installation guidance

Rockwool Flexi Slabs are light and easy to cut to any shape with a sharp knife. Ensuring a perfect insulation fit is essential to maintain the thermal and acoustic integrity of the wall. Typical softwood timber moisture contents can range between 6-30%, dependant on exposure to the elements. As a rule of thumb, timber will expand 1% for every 4% of moisture content. If installed when timber has the high moisture content, it can result in a potential 6 mm vertical void on each side, when the wood dries out. 

Flexibility

Rockwool Flexi expands into this void, ensuring thermal and acoustic integrity, while rigid insulations may leave a 6 mm gap, or even fall out. Where studs or joists are at 400mm centres, 400mm wide Rockwool Flexi is usable. Flexi is also fast and easy to friction fit between floor joists from below, before fixing the plasterboard ceiling. Once installed Rockwool Flexi does not require any maintenance.

Rockwool Flexi Standards and quality approvals.

Fire classification

Rockwool Flexi achieves a reaction to fire classification of A1, as defined in EN13501-1.

Thermal Performance
Rockwool Flexi has a thermal conductivity of 0.038W/mK and 0.035W/mK at 140 mm thickness and above.

Health and Safety

The safety of Rockwool stone wool has confirmation by current UK and Republic of Ireland health & safety regulations and EU Directive 97/69/EC: Rockwool fibres are not a possible human carcinogen. A Material Safety Data Sheet is available and can be downloaded from www.rockwool.co.uk to assist in the preparation of risk assessments, as required by the Control of Substances Hazardous to Health Regulations (CO SHH).

Environment

Rockwool insulation does not contain (and has never contained) gases that have ozone depletion potential (ODP) or global warming potential (GWP).
Rockwool is approximately 97% recyclable.
