For a comfortable interior, good insulation of the walls reduces the temperature flow and improves the acoustic quality. To answer these two problems, it is not necessary to undertake major works because there are simple and reliable solutions. To improve the insulation of the walls, no need to be a professional thanks to the new Graphite Climapor wall insulation which requires no restrictive implementation while combining ease of installation and performance. While walls are the second source of heat loss after roofing, wall insulation can significantly reduce heat loss. Made of expanded polystyrene laminated with paper or aluminum, this latest generation insulation offers 20% better insulation than traditional insulation. On the implementation side, the product is presented in a roll and can be installed as easily as a wallpaper. Once in place, the cracks and irregularities of the walls disappear and the rooms heat up more easily. Then, just paste the wallpaper of your choice over it to dress the wall. Note that there are also ready-to-use insulating panels to stick on the wall to be insulated and decorative insulating ceiling tiles to complete your project. From 15 euros in DIY supermarkets.
