Cornerstone Insulating Render is a dry ready mixed render and plaster designed as a lightweight fibred basecoat for external applications or a basecoat and topcoat for internal applications within a minimum of a two-coat render application. Available in the colour white.
Engineered with precision to enhance the thermal performance of solid walled masonry whilst exceeding the high vapour permeability and flexibility of a traditional NHL2 lime render. Utilising 100% pure natural hydraulic lime, recycled glass aggregates and conservation-appropriate additives, this lightweight render outperforms popular market alternatives. Available as standard with fibres and Saint-Astier® NHL2.
Well-suited for projects looking to reduce thermal losses within walls, with a measured K Value of 0.12, a 50mm application will improve the U value of a solid wall by 50% or more.
