Due to its roll form, this Sempatap Thermal insulation can be applied much like wallpaper. An adhesive and primer are added to the surface and then it is rolled out. With only a 10mm thickness, it won’t pose any issues with reflooring as it’s a negligible size and you don’t need to interfere with extending services such as electrics or plumbing.
On a standard solid 9-inch brick wall, this Sempatap Thermal insulation can make the wall up to 30% more efficient by providing a thermal resistance of 0.194m²K/W.
