What is Sisalation Insulation?

Sisalation is a premium reflective foil radiant barrier designed to combat heat transfer in residential and commercial buildings. Made from lightweight, durable materials, it reflects up to 97% of radiant heat, reducing energy costs and enhancing indoor comfort. Available in various grades like Sisalation FR 405 and Sisalation FR 430, it’s SABS-approved and widely used in roofing, walls, and industrial applications across South Africa.

Unlike traditional insulation, Sisalation combines thermal efficiency with moisture resistance, making it ideal for our hot, humid summers and chilly winters.
