Thermal liner KV600 is the most thermally effective member of the Wallrock wallpaper range. Being 4mm in thickness and offered in a roll of 15m, twice the coverage of standard Thermal Liner. KV600 offers significant energy savings, well in excess of the 15% standard Thermal Liner provides on typical solid brick external walls. KV600 works to save energy from the moment heating is turned on by slowing down the rate at which a cold walls soak up heat energy - and allowing the room to warm up considerably faster, in many cases more than halving warm up times, creating a comfortable room environment with less energy. This effect is valuable in any home with solid walls and even those with external or cavity insulation - especially where the heating is regularly turned on and off. Thermal Liner KV600 has excellent capacity to cover and reinforce poor plaster and other surfaces such as plasterboard, block-work and wood paneling. KV600 can also help to reduce condensation problems and in many cases. The surface of Thermal Liner KV600 is long lasting, durable and suitable for painting directly, although for a perfect finish we recommend cross lining with Wallrock Fibreliner (avoid the use of standard linings) which allows not only painting but the application of decorative wallpaper. We strongly recommend using our Wallrock Thermal Liner Adhesive for application of this durable heavy duty product.
