Step 1

Step 1

Lay the expansion foam around the perimeter of the room, ensuring the gaiter is facing into the room. The expansion foam should be fitted to the full depth of the floor insulation and screed.

NOTE: Where the expansion foam is installed on external walls, additional insulation will be required for compliance with building regulations.

Step 2

Step 2

Lay insulation (supplied by others) in accordance with building regulation requirements. The insulation should be laid hard up against the expansion foam with no gaps. Ensure that the foams’ gaiter is lying on top of the insulation to prevent the screed from flowing under the insulation.

Step 3

Step 3

Prior to laying the underfloor heating pipe, the insulation layer may need to be covered and fully taped with overlapping polyethylene sheets/membrane.

NOTE: Preparation and requirements for specialist screeds should be sought from the installation and screed supplier/manufacturer.
