Rated 5 out of 5 by Insulation Very happy with product and the very fast delivery. 17 Aug 2015
Rated 5 out of 5 by Odd job Needing to insulate a corner of the loft which is awkward to reach. The rolls of foil were light and small to allow my access (I am neither) easily positioned when unrolled; job done. The problem others have mentioned of the glue holding the roll shut being too strong seems to have been addressed. 15 Aug 2015
Rated 4 out of 5 by great product used to line inside of concrete shed roof, very easy to use/fix.have used before & will again, ideal for DIYERS but we use it profesionally 17 Jul 2015
Rated 4 out of 5 by ThermaWrap Loft Insulation I purchased at a more realistic offer price. My first observation was the tenacious glue applied to keep the roll intact. It needed severing by using a Stanley blade as scalpel to avoid damaging the roll - totally OTT. In use the foil is a dream to work with, being well behaved and easy to cut. I hope it contributes to my shed insulation. I will know more when autumn and winter come. It looks to be well made, with the foil well attached on both sides of the bubble film. 11 Jul 2015
