Therma-Foil Insulation in Walls

Timber frame and stud Walls:

Wall Insulation, Therma-Foil should be rolled out across the face of the frame or to support battens if required, and fixed in place using staples, join rolls as previously described. Counter batten frame to create an air-space on either side of the Therma-Foil. Alternatively, Therma-Foil can be loosely fitted to allow it to be dished back into the wall cavity. Cut out carefully around doors, windows and other openings, so that it neatly abuts to frame. Finish frame as per requirements and applicable standards.

Block wall insulation:

Therma-Foil can be used on solid block walls as wall insulation by battening the walls and fixing Therma-Foil to the battens. You should then counter batten and finish as per requirements and applicable standards.

Caution when using Therma-Foil for:

Always tape Therma-Foil when surfaces are clean and dry. The reflective surface should not be installed in direct contact with uncured concrete or any uncoated raw metals. Please use caution when working around electrical sources. Therma-Foil should not be exposed to open flames or ignition sources of sufficient intensity during shipment, storage or installation.

Our dining room above our cold and damp cellar made the room unapp  ealing to eat in as everyone complained their feet were cold. We fitted Therma-Foil under our laminate floor and we were astonished at the difference it made –not only were we surprised how much warmer the room was, but also how much softer and more comfortable the floor was to walk on.

Placing Therma-Foil over the floorboards beneath the carpet throughout our house has stopped the cold drafts that were coming through the gaps – it was so easy to install and has saved us a fortune in energy bills.  It’s so much warmer and made the roo

m feel more comfortable.

On moving into our apartment we soon realised that not only was our laminate flooring always cold but also the sound of us walking on it echoed throughout the rooms. Fitting Therma-Foil underneath has changed our lives – it’s now a much warmer home and much quieter
