36mm Soffit Liner Insulation Board (30mm RWA45 & 6mm Promat Masterboard) is an A1 class non-combustible soffit liner board that provides effective fire resistance, acoustic and thermal insulation for concrete soffits.

Soffit Liner Boards are manufactured using high performing, non-combustible Rockwool RWA45 insulation slab faced with 6mm Promat Masterboard, fire and moisture resistant reinforced calcium silicate building board.

This unique combination of two non-combustible fire rated products provides increased impact resistance and durability in addition to improved fire safety and ease to decorate with paints, wallpapers or tiles.

Insulated Soffit Liner Fire Board 36mm x 600mm x 1200mm provides a cost effective solution where a thermal, fire or acoustic performance is required in concrete car park soffits and similar applications.

The Masterboard is resistant to the effects of moisture and will not physically deteriorate when used in damp or humid conditions and will not encourage mould or bacteria growth.

These composite insulation panels are suitable for use as an insulated underlining solution in semi exposed structural soffits such as open-sided car parks.

Soffit Liner is an easy to handle lightweight but strong composite board that can be easily cut to accommodate services and simply butt joined together.

The thermal performance and acoustic insulation provided by the soffit liner board is highly effective.

Lambda value of Rockwool RWA45 insulation slab is 0.035W/mK.

Thermal conductivity of 6mm Promat Masterboard is 0.22W/mK.

Soffit Liner Insulation Board Installation Guide:

 · When commencing installation it is advised to start with a soffit liner board at the centre of the soffit when fixing a tile or modular system.

 · It is important to ensure that all the following boards will be fixed outwards towards each edge.

 · To aid in safeguarding the alignment of the installation, it is advised to use string lines or laser alignment equipment.

 · Each Soffit Liner Board should be fixed using e.g. Ejot DDS fixings with the Ejot DDT70 washer or similar, direct to the concrete soffit.

 · Pre-drill board and concrete to a depth of 5mm more than the anchor length.

 · Insert fixing and hammer or screw tight to line and level.

 · Care should be taken not to damage the surface of the liner boards by over-tightening the fixing.

 · Light fittings and services should be supported from the concrete soffit.

 · Do not use Soffit Liner Boards to support these types of installations.
