DESCRIPTION

Warmup Insulation Boards are manufactured from water resistant extruded polystyrene, finished on both faces with a thin layer of fibreglass reinforced cement. They are available in a range of thicknesses, from 6mm to 50mm, to individual project requirements.

They are ideal for tile backing applications on both walls and floors, with the internal layer of insulation capable of supporting 30 tonnes per square metre. The 0.5mm thick cement coating provides an excellent surface for tile adhesive, plaster and smoothing/levelling compounds, with no priming required.

The low thermal conductivity of the insulation enhances the efficiency of underfloor heating systems, even when used over pre insulated sub floors. This is because they reduce the thermal mass of the floor, significantly reducing the amount of heat absorbed by the subfloor. This allows the underfloor heating system to warm the floor and the room up faster and ensures the floor cools down faster after use. By reducing the amount of time the room takes to warm up and cool down, the room can spend longer at its cooler set back temperature, reducing its heat loss.

The waterproof insulation panels are suitable for bathrooms and showers as well as dry rooms, allowing the same construction to be used throughout.

INSTALLATION GUIDE

Installation (Floors)

Concrete Floors

STEP 1 - The subfloor must be clean and dry and if necessary, smoothed with a latex/cement self-levelling compound to give an SR1 surface regularity.

STEP 2 - The insulation board should be installed using a flexible, cement-based adhesive. The adhesive should be trowelled out and combed through with a 6/8 mm notched trowel to give a ribbed bed, any slight depressions being filled by the mortar.

STEP 3 - The boards should be laid on the freshly applied ribbed bed and thoroughly bedded in to ensure that no voids are left beneath the boards and they are solidly supported. All boards should be laid with staggered joints.

Timber Floors

STEP 1 - The subfloor must be clean and dry. Existing floorboards should be structurally sound and if necessary, smoothed with a latex/cement self-levelling compound to give an SR1 surface regularity.

STEP 2 - The insulation board should be installed using a flexible, cement-based adhesive. The adhesive should be trowelled out and combed through with a 6/8 mm notched trowel to give a ribbed bed, any slight depressions being filled by the mortar.

STEP 3 - The boards should be laid on the freshly applied
ribbed bed and thoroughly bedded in to ensure that no
voids are left beneath the boards and they are solidly supported. All boards should be laid with staggered joints.

STEP 4 - When the adhesive has cured, the boards should be secured using screws and washers. These are installed at the rate of 12 per board (3 rows of 4). The screws should be a minimum of 30 mm from the edge of the insulation board. Tighten the screw and washer into the board until the screw head is flush with the surface.

NOTE: Allow the adhesive attaching the boards to the subfloor to cure before laying electric underfloor heating directly onto the boards. Tile over heater using cement-based flexible adhesive and grout.

WATERPROOFING: To attain waterproof joints the boards should be sealed during installation using silicone 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.

Installation (Walls)

Solid walls

STEP 1 - The substrate must be clean and dry. It is possible to adhere the boards to existing plaster however plastered walls must be sealed before fixing the boards.

STEP 2 - The insulation board should be installed using a flexible, cement-based adhesive. The adhesive should be trowelled out and combed through with a 6/8 mm notched trowel to give a ribbed bed, any slight depressions being filled by the mortar.

STEP 3 - The boards should be laid on the freshly applied ribbed bed and thoroughly bedded in to ensure that no voids are left beneath the boards and they are solidly supported. All boards should be laid with staggered joints.

NOTE: Allow the adhesive attaching the boards to the substrate to cure before laying electric wall heating directly onto the boards. Tile over heater using cement-based flexible adhesive and grout.

Stud walls

IMPORTANT: For stud walls at 600 mm centres you must use 20 mm insulation boards or thicker. 10 mm boards are suitable for stud walls at 300 mm centres only.

STEP 1 - All board edges must be supported by noggins. Install noggins between studwork where board edges are likely to need supporting.

STEP 2 - The insulation board should be installed using screws and washers. These should be applied every 300 mm on each stud. For studs at 600 mm, use 2 rows of 5 fixings. At 300 mm centres use 3 rows of 5 fixings. All boards should be laid with staggered joints.

STEP 3 - Tighten the screw and washer into the board until the screw head is flush with the surface.

NOTE: Electric wall heating can be applied directly onto the boards. Tile over heater using cement-based flexible adhesive and grout.

WATERPROOFING: To attain waterproof joints the boards should be sealed during installation using silicone 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.
