50mm Unilin SR/FB is an insulation board designed for use with steel or timber frame applications up to 11m in height, SR/FB can be also used between studs or as an insulated sheathing board.

Safe-R SR/FB 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.

In timber framed systems SR/FB effectively insulating the Thermal Bridging caused by the timber studding drastically improves the insulation value of the walls.

Buildings constructed using a steel framed system are insulated on the outer side of the construction creating a ‘Warm Frame’, reducing the risk of condensation.

The low emissivity foil facing on Safe-R SR/FB Framing Board improves the thermal performance of the wall within an unventilated cavity.

The unventilated cavity, or residual cavity, is the most effective method of preventing wind-driven rain penetrating a wall from the outside.

Requirements for buildings over 11m in height must meet specific targets under Building Regulations - SR/RS Framing Board is suitable for buildings under 11m in height.

SR/FB Framing Board is durable, rot proof and sufficiently stable to remain effective as floor insulation for the life of the building.

Unilin SR/FB Framing Insulation Board Installation Guidelines:

 · Timber Framed System - Cut glass fibre insulation or Safe-R Framing Board to fit snugly between the timber studding.

 · Allow slight oversize of cut to achieve ‘friction fit’ and seal any gaps with suitable expanding foam.

 · If partially filling, ensure the insulation is securely held in place by treated timber battens in order to prevent framing board moving within the cavity.

 · Ensure boards are closely butted.

 · When using Safe-R Framing Board as a sheathing board, fix the insulation outside of any breather membrane or timber sheathing on the external surface.

 · A second breather membrane may be added at this point for further protection) and temporarily fixed with large head clout nails.

 · Ensure boards are closely butted and stagger jointed.

 · Place a sealed vapour control layer of polythene with lapped and sealed joints over the internal stud face.

 · Install cavity barriers into the cavity as required under building regulations.

 · Apply the internal finish as normal using fixings as recommended by the timber frame supplier.

 · Steel Framed System - As with timber framing, Safe-R Framing Board should be fixed to the outer face of the steel frame ensuring that vertical joints meet over a metal stud.

 · Fixings should be in accordance with the steel system manufacturers recommendations and BBA Agrément approved.

 · Ensure boards are closely butted.

 · Place a sealed vapour control layer with lapped and sealed joints over the inner stud face.

 · Install cavity barriers into the cavity as required under building regulations.

 · Apply the internal finish as normal.

 · Fix wall ties as recommended by the steel frame supplier.

 · Ventilated Cladding - Fix treated battens or propriety framing system vertically to the wall through the insulation layer, ensuring that the system is fixed securely to the substrate.

 · Fixings should be appropriate for the weight of the cladding system, seek advice from the fixing manufacturer.

 · Horizontal tiling battens can be fixed to the vertical battens if the cladding system is to be tile hung, or the cladding fixed directly to the vertical battens.

 · An approved breather membrane may be required as part of the design.

 · Cladding system should be fixed in accordance with the manufacturer’s recommendations.

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