30mm Rockwool RW3 White Tissue Faced Two Sides Slab is a 60kg/m3 density insulation slab faced with white tissue on both sides, used as a fire resistant and thermal insulation for roofs, concrete car park soffits and similar applications.

An unique white tissue facings on both sides helps to avoid the slab edges from showing as shadows through the perforated inner sheet and assists in preventing fibre migration, providing approx. 4 times less fibre migration-bullet.

Rockwool RW3 Insulation Slab 30mm x 600mm x 1200mm faced with white tissue on 2 sides can provide from 30 minutes up to 240 minutes fire protection to the underside of concrete soffits and double skinned metal roofing systems.

White Tissue Faced Two Sides Rockwool RW3 30mm is a medium density 60kg/m3 rigid soffit insulation slab with a certified thermal conductivity (lambda value) of 0.034 W/mK and an excellent fire performance Euroclass A1.

Rockwool Slab is an ideal sound absorber as it 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.

The structure of the fibres in Rockwool RW3 insulation slabs make them ideal for use as a sound absorber with water repellent qualities of the insulation preventing moisture build up, damp and rot.

Rockwool RW3 White Tissue Faced Two Sides Slab is a robust long-lasting insulation product made from renewable resources which will maintain high performance over the lifetime of the building.

These fire, thermal and acoustic Rockwool RW3 white tissue faced 2 sides insulation slabs are free of CFCs and HCFCs and will not encourage the growth of fungi, mould or bacteria.

RW3 60kg White Tissue Faced 2 Sides Slab works in two ways to reduce noise, either by absorption of sound at the surface or inhibiting its transmission.

Achieved absorption coefficient of the product will vary according to thickness and density of the slab and application where it is used.

White Tissue Faced Two Sides Rockwool RW3 (60kg) Insulation Slab Installation Guide:

 · When fixing a tile or modular system, it is advisable to start with a focus reference slab in the centre of the soffit with subsequent slabs being fixed working towards each edge.

 · The use of string lines or laser alignment equipment will assist in ensuring alignment and squareness of the installation.

 · If RW3 is installed into a concrete or steel composite deck, a pilot hold should first be drilled prior to the fixing being screwed into place.

 · Rockwool RW3 Soffit and Roof Slabs should be fixed directly to the concrete soffit using Ejot DDS fixings with the Ejot DDT70 washer or similar.

 · Care should be taken not to over-tighten fixings to prevent damage to the white tissue faced slab surface.

 · For further information on fixing type and suitability for the substrate, please refer to the fixing manufacturer.

 · It is recommended that all white tissue faced slab joints should be staggered and tightly butt jointed.

 · Soffit insulation RW3 slabs should not be used for supporting light fittings or services.

 · Such installations should be supported from the concrete soffit.

 · Where penetrations occur, the boards should be cut locally to ensure a tight fit around the penetration.

 · White Tissue Faced RW3 Slabs can be cut slightly oversized to ensure a tight fit under slight compression around the penetration.

 · Any small gaps that result from cutting can be infilled using the Acoustic Intumescent Sealant.

RW3 White Tissue Faced 2 Sides Slab Health and Safety Regulations:

 · The safety of Rockwool stone wool is confirmed by current UK and Republic of Ireland health & safety regulations.

 · We advise you to use PPE (personal protective equipment) including some gloves and a face mask.

 · Rockwool stone wool insulation fibres are not classified as a possible human carcinogen.

 · The mechanical effect of fibres in contact with skin may cause temporary itching.

 · Cover exposed skin during the handling and installation process.

 · When working in an unventilated area, wear a disposable face mask.

 · Clean working area using vacuum equipment.

 · Waste should be disposed of according to local regulations.

 · Rinse in cold water before washing.

 · Ventilate the working area if possible.

 · Wear goggles when working overhead.
