WARMUP INSULATION BOARD is a water resistant insulated tile backer board made of extruded polystyrene, faced on both sides with a fibreglass mesh embedded into a thin cement polymer mortar.
Length: 1250mm / Width: 600mm / Thickness: 10mm
 
Installation onto timber floor

</SPAN />Ensure that adequate underfloor ventilation is provided. Existing floorboards should be securely and rigidly fixed (refer to BS 5268 : Part 2 : 1991 regarding minimum floor stiffness and rigidity).

The surface of the floorboards should be painted with primer, applied as a thin even coat using a short pile paint roller, and allowed to dry to a clear, tacky film.

The Warmup Insulation Board should be bedded onto the dry primed floor using a flexible, cement-based adhesive. The adhesive should be trowelled out and combed through with the recommended notched trowel to give a ribbed bed, any slight depressions being filled by the mortar.

The Warmup Insulation Board should be laid on the freshly applied ribbed bed and thoroughly bedded in to ensure that, as far as is possible, no voids are left beneath the boards and they are solidly supported. All boards should be laid with staggered joints. To attain waterproof joints the boards should be sealed during fixing using Silicon sealant. The sealant should be applied to the edge of the fixed board immediately prior to the next board being installed and placed in position.
When this adhesive has set but not necessarily dried, the boards should be supplementary fixed using a screw fixing and washer. These are fixed at the rate of 5 per square metre. The fixings should be a minimum of 30mm from the edge of the Warmup Insulation Board.

The screw washer fixing is tightened into the board until the screw head is flush with the surface.
If required, it may be driven flush with the board surface using a rubber headed mallet and the screw re-tightened.

In wet areas, we recommend that the fixing hole be primed with Silicon Sealant prior to inserting the fixing. The joints should then be reinforced with a self adhesive glass fibre tape approximately 50mm wide.
