The 150mm Unilin XO/UF Floorboard is used for underfloor heating, solid and suspended floors, a rigid foam PIR insulation core with textured robust low emissivity aluminium foil facings.

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

XO/UF Underfloor provides the strength and thermal properties required to reach the high performance U-Values asked for in the Building Regulations.

Unilin XO/UF is a superior performance insulation with a lambda (thermal conductivity) value of 0.021 Wm/K and a Euroclass C fire classification.

XtroLiner Underfloor XO/UF will significantly improve the U-Value of new and existing floors.

The floor in any building is an area of considerable downward heat loss when not properly insulated.

Unilin XO/UF XtroLiner Floorboard 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 XtroLiner Underfloor across the DPM.

 · If two layers are required, lay the boards in a staggered jointed pattern and closely butt all edges.

 · 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 insulation boards 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 XtroLiner Underfloor boards across the DPM.

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

 · Separating layers 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 insulation boards through the separating layer 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 XtroLiner Underfloor to size, allowing for variations in joist spacings.

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

 · 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 XtroLiner Underfloor 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.
