100mm SR/UF Unilin Floor Insulation Board is a superior performance rigid phenolic foam insulation with enhanced fire performance and composite foil facings, for use in floor applications.

SR/UF provides the most efficient means of floor insulation as it has the strength and thermal properties required to reach the high performance U-values asked for in the Building Regulations.

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

The floor in any building is an area of considerable downward heat loss when not properly insulated, SR/UF will significantly improve the U-value of new and existing floors.

SR/UF is lightweight, easy to install and combines high compressive strength with low thermal conductivity, providing a high performance solution for floor insulation.

Safer-R SR/UF is lightweight and suitable for use with underfloor heating, thanks to its thickness to performance ratio, SR/UF allows for reduced insulation thickness.

Floorboard SR/UF should be laid with closely butted joints, laid staggered with a break bonded pattern and fitted tightly at edges and around any service penetrations.

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

Unilin SR/UF Phenolic Floor Insulation Board Installation Guidelines:

 · Below Concrete Slab - Lay and level the hardcore in layers 150mm min/250mm max and compact well.

 · Sand blind base to create a level surface and to protect DPM.

 · The damp proof membrane (DPM), normally 1200g polythene or radon barrier, should be laid over the blinding, tape lapped joints to prevent passage of ground moisture.

 · Carry DPM up to the wall to meet and seal with the DPC course (contact the membrane manufacturer for further guidance on installation and best practice).

 · Lay the SR/UF across the DPM, If two layers are required, lay the boards in a staggered jointed pattern and loosely butt all edges.

 · Place Safe-R Perimeter Strips SR/STR around floor perimeter to provide robust detailing in order to reduce thermal bridging.

 · Ensure the top of perimeter strip is level with top of floor finish and seal around any service penetrations.

 · Lay a thin gauge polythene sheet, to act as a separating layer, over the insulation with 150mm lap joints.

 · VCL should be taped at the joints to ensure a continuous separating layer, as per BRE GBG 45 “Insulating Ground Floors”.

 · Pour and compact concrete slab to required finish floor level.

 · Below Floor Screed - Lay and level the concrete slab, allowing sufficient time to dry out, as per BS 8203.

 · Beam and block floors may need a levelling screed or grouting to ensure base level (refer to manufacturer’s guidelines).

 · The damp proof membrane (DPM), normally 1200g polythene or radon barrier, should be laid over the blinding, tape lapped joints to prevent passage of ground moisture.

 · Carry DPM up to the wall to meet and seal with the DPC course (contact the membrane manufacturer for further guidance on installation and best practice).

 · Lay the SR/UF boards across the DPM, If two layers are required, lay the boards in a staggered jointed pattern and closely butt all edges.

 · Place Unilin Perimeter Strips (SR/STR) around the floor perimeter to provide robust detailing in order to prevent thermal bridging.

 · Ensure top of perimeter strip is level with top of floor finish and eal around any service penetrations.

 · Layer a thin gauge polythene sheet, to act as a separating layer, over the insulation with 150mm lap joints.

 · VCL should be taped at the joints to ensure a continuous separating layer, as per BRE GBG 45 “Insulating Ground Floors”.

 · If underfloor heating is required, lay pipes and clip to SR/UF through the VCL and follow manufacturer’s guidelines.

 · Pour screed according to screed manufacturer’s guidelines.

 · Suspended Timber Floor - Install joists in the normal manner, ensuring adequate ventilation.

 · Measure gaps between joists and cut SR/UF to size, allowing for variations in joist spacings.

 · Mechanically fasten treated timber battens to the joists, allowing for correct thickness of insulation.

 · Galvanised nails or saddle clips may also be used, ensuring nails are left 40mm proud of the joists.

 · Install SR/UF between joists with joints tightly butted and seal any gaps with expanding foam.

 · If two insulation layers are required, lay the boards in a staggered jointed pattern, also sealing any gaps with expanding foam.

 · Floor boards should be laid directly to the joists.

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