Heatsaver is an economical 2mm thick polystyrene liner containing fire retardants that provide basic insulation as well as combating condensation problems and subsequent mould growth for a healthier home. To create a more durable and smoother surface we recommend the surface is overlined - Wallrock fibreliner is particularly tough and strong.
This product is suitable as a localised ‘problem solver’ for cold external walls and is not recommended for use in fire escape routes inside your home unless the surface is further treated with a fire retardant covering. This product is class E fire rated and should not be used for projects such as new builds and extensions where Building regulations are applicable.

This is a simple wallpaper calculator and should be used as a guide only. You can find the roll width and roll length you are after on the specific product page.Roll widths are provided in meters (such as 0.5 x 10mtr) so your wall widths and heights should be inputted in meters also.If you are purchasing an offset match product then you may need a little extra as there may be some waste. If you have any windows or doors in your walls you can simply ignore these. This will give a good estimate of required roll numbers.
