100mm Thin-R Plus XT/HYF Unilin Floorboard is a lightweight floor PIR rigid insulation board suitable for use with underfloor heating, ground supported and suspended floors.

Unilin Hyfloor XT/HYF has a superior thickness to performance ratio, allowing the lower targets required under Building Regulations to be achieved with minimum thickness.

XT/HYF T&G jointing system offers a practical on-site solution that results in a more robust continuous layer of insulation, minimising the threat of thermal bridging.

Unilin Floor Boards are tongue and grooved insulation panels with high compressive strength of 140kPa and very good thermal properties.

Floorboards should be laid staggered in a break bonded pattern and fitted tightly at edges and around any service penetrations.

XT/HYF insulation is the answer to achieve lower U-Values – in a practical and robust manner.

The XT/HYF PIR floorboard achieves an A + rating under the BRE Green Guide.

Unilin XT/HYF HYFLOOR Thin-R Plus 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 Hyfloor across the DPM.

 · If two layers are required, lay the boards in a staggered jointed pattern.

 · Closely butt all edges.

 · Place Unilin Perimeter Strips (XT/STR) around floor perimeter to provide robust detailing in order to reduce Thermal Bridging.

 · Ensure the top of the perimeter strip is level with top of floor finish.

 · 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”.

 · If underfloor heating is required, lay pipes and clip to the Hyfloor through the separating layer.

 · Follow UFH manufacturer’s guidelines.

 · 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 Hyfloor boards across the DPM.

 · If two layers are required, lay the boards in a staggered jointed pattern.

 · Closely butt all edges.

 · Place Unilin Perimeter Strips around the floor perimeter to provide robust detailing in order to prevent Thermal Bridging.

 · Ensure the top of the perimeter strip is level with the top of the floor finish.

 · 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”.

 · If underfloor heating is required, lay pipes and clip to the Hyfloor through the separating layer.

 · Follow manufacturer’s guidelines.

 · Pour screed according to screed manufacturer’s guidelines.
