Cornerstone SuperTherm is a premixed dry lime plaster that serves as an exceptionally lightweight and low-density fibred basecoat, specifically intended for use in a minimum two-coat rendering system for interior spaces. This product is offered in a classic white shade.
Meticulously engineered, this internal lime plaster boasts outstanding insulating capabilities. It incorporates an advanced foamed aggregate featuring a nanometre pore structure, effectively reducing heat loss through the building’s outer layers. The plaster comes standard with reinforcing fibres and high-purity Calcium Hydroxide combined with pozzolan.
This solution is ideal for projects that demand an ultra-lightweight plaster with remarkable insulation features. With a measured K Value of 0.04, applying it at a thickness of 50mm can enhance the U value of a solid wall by over 75%.
