ThermaWrap Loft Insulation 0.4 x 5m 4.2 5 20 20
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
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
INSULATE METAL SHEDS Used the foil to insulate the roof of a metal building. Easy to cut and apply with a contact adhesive and can be wrapped around the ridge and roof supports which tend to produce a lot of condensation drips in the winter. Don't know how good it will be at preventing condensation until winter but it should work. 2 stars for performance so far. 26 Jun 2015
Very good insulation I used this to hold loose insulation against the loft conversion. I stapled it to the wood. It's very easy to cut and mould around awkward areas and definitely keeps the winter heat in and the summer heat out of the loft conversion. The glue that holds the roll together is way too powerful and I ended up having to cut through the glue rather than tear the insulation apart. 1 Apr 2015
