Rated 5 out of 5 by Great heat/damp proof material I use the wrap to insulate storage boxes, its great in both summer and winter, does a great job protecting from the elements. My ceramics studio is a loglap cabin and gets very cold in the winter when the heater isn't on. I have a lot of plaster and powdered materials as well as liquid glazes and latex etc that go off in the cold if get frost inside them. Would highly recommend this product for a wide variety of uses, also great to staple to inside of shed to help with heat. The range of sizes available to purchase makes it great for many uses. 19 Nov 2015
Rated 5 out of 5 by Good stuff It's the most simple stuff to use, just roll it out and staple it in to place, it takes about 4 rolls to do a normal size room 6 Nov 2015
Rated 4 out of 5 by Insulation I have not used the product yet, but from the specification it looks like product is of good value. 23 Oct 2015
Rated 4 out of 5 by Ok for Garden Shed I needed something cheap to line my garden shed. Although it looks like glorified foiled bubblewrap it does have some heat retention properties. Easy to unroll and staple, early days yet but I should imagine its better then doing nothing unless you want to spend alot. 21 Oct 2015
