Don’t take it from us, see what our customers think about Therma-Foil under their floors.

Our dining room above our cold and damp cellar made the room unappealing  as everyone complained they 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. We also noticed how much softer and more comfortable the floor was to walk on.  J Bales, Edinburgh

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 room feel more comfortable.  Sally Howard, Lytham

On moving into our apartment, we soon realised that not only was our laminate flooring always cold. 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.  Mrs M McNairn, Aberdeen
