Provides on typical solid brick external walls. Works to save energy from the moment heating is turned on by slowing down the rate at which cold walls soak up heat energy and allows the room to warm up considerably faster. Creating a comfortable room environment with less energy. Valuable in any home with solid walls and with external or cavity insulation where the heating is regularly turned on and off. Excellent capacity to cover and reinforce poor plaster and other surfaces such as plasterboard, block work and wood panelling. Helps reduce condensation problems as much more room warmth is retained in the wall surface at an earlier stage, there is less opportunity for condensation to form on a cold wall and reduces risk of mould growth. 15m² Coverage Per Pack Smooth Matte Finish Suitable for Lounge, Bedroom & Dining Room Paste the Wall Application Non-Washable 15m² Coverage Per Pack Smooth Matte Finish Suitable for Lounge, Bedroom & Dining Room Paste the Wall Application Non-Washable
