A specialist thermal lining paper that offers so many benefits. Specially developed by Erfurt Mav, it is primarily an energy saving and wall insulation product that utilises technology originally developed for aerospace. Made from a technologically advanced thermal insulation material bonded to a high quality lining paper, Wallrock Thermal Liner creates a warm blanket for your walls and ceilings which significantly reduces room warm up time, stops heat escaping through walls and ceilings, minimises condensation, mould and damp, and reduces your energy bills too. Because it is so thick (3.2mm), it also provides a substantial amount of sound insulation, reducing noise by up to 35%. In addition, it covers up rough or damaged walls to transform them into a flat finish.
