Cornerstone SuperTherm is a dry ready mixed lime plaster designed as an ultra-lightweight and low density fibred plaster to enhance the thermal insulation of solid walled masonry. Developed using innovative foamed aggregate technology, this specialist insulating lime plaster delivers exceptional thermal performance while maintaining the breathability and moisture management benefits associated with traditional lime construction.
Its innovative technology with a nanometre pore structure prevents the directional flow of heat therby minimising heat loss through the building envelope. Supertherm plaster is breathable and supports moisture management. It is made to improve indoor air quality and thermal comfort.
This ultra-lightweight plaster with exceptional insulating properties is designed as a fibred basecoat for internal applications within a minimum of a two-coat plaster system. When used as part of a complete insulation build-up, the application will improve the U value of a solid wall and can significantly reduce heat loss, helping create more energy-efficient and comfortable internal environments.
Manufactured using high-purity Calcium Hydroxide, pozzolan technology and specialist foamed aggregate materials, SuperTherm plaster provides a lightweight alternative to traditional plaster systems. The low-density composition makes it particularly suitable for projects requiring an ultra-lightweight plaster while still delivering excellent adhesion, workability and durability.
