50mm Unilin SR/ST Soffit Board is an effective thermal and fire performance solution used in structural ceiling applications in commercial and residential buildings, a high performance phenolic insulation.

Soffit Board Unilin Safe-R SR/ST can be used as an insulation in exposed concrete floor decks in car parks, storage areas, loading bays and similar areas beneath habitable buildings.

Using SR/ST on soffit areas, whether new build or refurbishment situations, provides the most efficient U-Values with minimal thickness of insulation.

Unilin Safe-R SR/ST is manufactured to EN 13166 by Unilin Insulation with certified lambda (thermal conductivity) of 0.020 W/mK and Euroclass C-s1 d0 fire classification.

Safe-R SR/ST Soffit can be fixed directly to the concrete slab, onto battens or used with proprietary fixing systems, to provide an even surface.

SR/ST Soffit Board is a lightweight rigid insulation product and is convenient to handle to allow for fast and easy fixing.

Safe-R Soffit is finished with a foil facer which can be taped using a proprietary foil tape.

SR/ST is durable, rot proof and sufficiently stable to remain effective as soffit insulation for the life of the building.

Unilin Safe-R SR/ST is a cheaper alternative to Kingspan Kooltherm K110 Soffit Insulation.

Unilin Safe-R SR/ST Soffit Insulation Board Installation Guidelines:

 · Directly to Concrete - Where applicable, ensure cavity wall insulation has continued past the soffit insulation to reduce Thermal Bridging.

 · Install Safe-R Soffit onto the soffit ensuring all joints are supported.

 · The boards should be tightly butt jointed, laid staggered in a break bonded pattern and fitted tightly at edges and around any service penetrations.

 · Any gaps or service penetrations should be addressed with propriety fillers and components in accordance with fire engineers specifications.

 · Fix Safe-R Soffit to soffit with approved fixings*, ensuring the fixings penetrate the substrate by a minimum of 40mm.

 · Generally 12 fixings (min shank diameter of 5.2mm) per board are required.

 · Fixings should have a head diameter of at least 35mm.

 · Distribute fixings evenly across the board, at max 600mm across and 800mm along, at a minimum of 50mm from the board edge and a maximum of 150mm.

 · It is recommended to seek advice from the fixing manufacturer for specific guidance.

 · Boards joints can be covered with a suitable cover strip.

 · Fixing to Timber Battens/Proprietary Systems - Treated timber battens may be used to provide an even surface when direct fixing to the soffit is not possible.

 · Battens should be treated timber, measuring minimum 50mm x 40mm, and should be mechanically fastened at minimum 600mm centres.

 · Fix Safe-R Soffit to the timber battens with approved fixings*, ensuring the fixings penetrate the substrate by a minimum of 40mm.

 · Ensure joints are tightly butted and fill any gaps with expanding foam.

 · Generally 12 fixings (min shank diameter of 5.2mm) per board are required.

 · Fixings should have a head diameter of at least 35mm.

 · Distribute fixings evenly across the board, at max 600mm across and 800mm along, at a minimum of 50mm from the board edge and a maximum of 150mm.

 · Refer to fixing patterns above for indicative purposes.

 · It is recommended to seek advice from the fixing manufacturer for specific guidance.

 · When using proprietary metal grid systems, refer to the manufacturer for fixing instructions.

 · Board joints can be covered with a suitable cover strip.

 · Fixing* type and specification should be verified by the fixing manufacturers' design, to take account of topographical and fire considerations.

 · Account should be taken of any Thermal Bridging through the fixings as should the effect of any supporting beams.

 · Fixing manufacturers: Ejot or Fischer.

 · ACDs must be followed to ensure that installation is in accordance with current Building Regulations and accounted for in the energy calculation.
