25mm Knauf RS60 Black Tissue Faced Insulation Slab is an acoustic rock mineral wool based, class A1 non-combustible insulation slab, used for structural elements such as roofs, concrete car park soffits and similar applications.

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

Black tissue facing on 1 side 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.

The 25mm x 600mm x 1200mm Knauf Rocksilk RS60 Soffit Insulation Slab faced with black tissue on one side can provide from 30 minutes up to 240 minutes fire protection to the underside of concrete soffits.

Rocksilk 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 1 Side Insulation Slabs are used for the thermal, fire and acoustic insulation of soffits in a wide range of both residential and non-residential buildings.

This special Black Tissue Faced on One Side Knauf Rocksilk RS60 Insulation Slab is suitable for use as an insulated underlining solution in structural soffits such as underground car parks.

Rocksilk RS60 Black Tissue Faced 1 Side 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 Knauf RS60 (60kg) will have a life equivalent to that of the structure in which it is incorporated.

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

Knauf RS60 (60kg/m3) Black Tissue Faced One Side 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 Rocksilk 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 Insulation 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.

RS60 Slab Black Tissue Faced 1 Side Safety:

 · Knauf Rocksilk RS60 Soffit Liner Slabs (Boards) 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.
