56mm Unilin SR/STP Soffit Plus Board is an effective thermal and fire performance solution used in the structural ceiling, a rigid foam phenolic core bonded to an impact resistant 6mm building panel.

Safe-R SR/STP Soffit Plus Insulation Board is finished with an impact resistant 6mm building panel which offers a secure finish for ease of maintenance and easily accepts decorative finish.

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

The bonded facing of non combustible building panel is water and impact resistant providing a durable protection to which a decorative finish may be applied.

Using Safe-R Soffit Plus on soffit areas, whether new build or refurbishment situations, provides the most efficient U-Values with minimal thickness of insulation.

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

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

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

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

Unilin Safe-R SR/STP Soffit Plus 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 Plus onto the soffit ensuring all joints are supported.

 · The SR/STP 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 Plus 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.

 · SR/STP Boards joints can be covered with a suitable cover strip (acrylic tape).

 · 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 Plus 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 fire retardant 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 (acrylic tape).

 · 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, Fischer or Rawlplug Washers and Firebreak Fixings.

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