Cornerstone SuperTherm is a dry ready mixed lime plaster designed as an ultra-lightweight and low density insulation layer and fibred basecoat for internal applications within a minimum of a two-coat plaster application. Available in the colour off-white.
Manufactured by Cornerstone to provide a revolutionary internal lime plaster with an unmatched insulating performance. Utilising an innovative foamed aggregate with a nanometre pore structure that prevents the directional flow of heat that results in heat loss through the building envelope while providing moisture management. Available as standard with fibres and a high-purity Calcium Hydroxide with pozzolan.
As part of the Cornerstone range of insulating renders and plasters, Cornerstone SuperTherm provides an innovative solution that functions as both a base coat plaster and a high-performance thermal layer.
Well-suited for projects requiring an ultra-lightweight plaster with exceptional insulating properties, with a measured K Value of 0.4, a 50mm application will improve the U value of a solid wall by more than 75%.
