Insulation Board Installation
Installation onto concrete floor
Existing concrete bases should be mechanically prepared removing all traces of existing finishes, contamination, etc., to expose a clean surface.
New concrete bases should be adequately cured and dried to allow shrinkage to occur prior to installing the Warmup Insulation Board.
The Warmup Insulation Board should be bedded onto the prepared base using a flexible cement-based adhesive. The adhesive mortar should be trowelled and combed through with a suitable 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 of adhesive 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. To attain waterproof joints, the boards should be sealed during 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.
Tile Installation
Tiles should be minimum 6 x 6" and installed using a thinset to ensure no voids are left underneath the tiles. Once the tile bed has hardened sufficiently, the joints between the tiles can be grouted using an appropriate grout mortar incorporating a flexible additive.
Installation using Warmup Underfloor Heating
Concrete must be clean and dry.
- Use cement-based flexible adhesive to attach boards to subfloor
- Stagger board joints
- Cover joints with self-adhesive glass fibre tape
- Allow adhesive attaching board to subfloor to dry
- Lay heater directly onto board ( do not prime board unless tape will not adhere due to dust)
- Tile over heater using cement-based flexible adhesive and grout
Installation onto timber floor
Ensure that adequate underfloor ventilation is provided. Existing floorboards should be securely and rigidly fixed.
The Warmup Insulation Board should be installed 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, 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 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.
When this adhesive has set but not necessarily dried, the boards should be secured using a screw and washer. These are installed at the rate of 1 per 2 sq. ft. The screws should be a minimum of 1.2" from the edge of the Warmup Insulation Board.
The screw washer 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.
