Knauf RS60 Black Tissue Faced 2 Sides Insulation Slab is a 25mm thick fire and acoustic rock mineral wool insulation slab, used for providing fire resistance and thermal insulation for roofs, concrete car park soffits and similar applications.

Rocksilk RS60 Slab (25mm x 600mm x 1200mm) faced with black tissue on both sides has the highest fire rating for non-combustible material and can provide from 30 up to 240 minutes fire protection to the underside of concrete soffits.

The black 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.

Knauf Rocksilk RS60 is a special medium-density (60kg/m3) insulation slab with a certified thermal conductivity (lambda value) of 0.034 W/mK and excellent sound absorption characteristics providing high levels of sound reduction.

RS60 Soffit Linerboard is non-combustible with the best possible Euroclass A1 reaction to fire classification, and is manufactured using Knauf Insulation's unique bio-based binder, ECOSE® Technology.

Knauf Rocksilk RS60 Black Tissue Faced 2 Sides Insulation Slab 25mm is used for the thermal, fire and acoustic insulation of soffits in a wide range of both residential and non-residential buildings.

Black Tissue Facings on both Sides of Knauf Rocksilk RS60 Insulation Slabs are suitable for use as an insulated underlining solution in structural soffits such as underground car parks.

Rocksilk RS60 Black Tissue Faced 2 Sides Soffit Slabs are odourless, rot proof, non-hygroscopic, do not sustain vermin and will not encourage the growth of fungi, mould or bacteria.

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

Black Tissue Faced Two Sides Knauf RS60 will have a life equivalent to that of the structure in which it is incorporated.

Knauf RS60 Insulation products made with ECOSE Technology contain no formaldehyde binder, dye or artificial colours.

Knauf RS60 Black Tissue Faced on Both Sides 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 installed into concrete or steel composite deck, a pilot hold should first be drilled prior to the fixing being screwed into place.

 · Knauf RS60 Soffit 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 Knauf RS60 slab surface.

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

 · It is recommended that all board joints should be staggered and tightly butt jointed.

 · Soffit insulation products 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.

 · RS60 (60kg) 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.

Black Tissue Faced 2 Sides RS60 Slab Handling and Safety:

 · Knauf Rocksilk RS60 Soffit LinerSlabs (LinerBoards) are easy to handle.

 · Care should be exercised to avoid crushing the edges or corners.

 · Damaged, contaminated or wet products must not be used.

 · During construction exposed areas of slabs should always be covered at the end of a day’s work or in heavy rain.

 · Polyethylene covers should be used to provide protection and prevent work from becoming saturated.

 · It is recommended that the Personal Protective Equipment (PPE) should be used while handling the product.

 · Dust mask (FFP1 minimum), gloves, safety glasses.

 · Knife or fine-toothed saw, tape measure.

 · It is recommended that dust masks, gloves and long-sleeved clothing should be worn during cutting and handling of the product.
