    SuperFOIL SFTV insulation is the ultimate all-purpose building membrane, suitable for floors, walls, and roofs, offering water and vapor resistance for any project. Its foil radiant barrier minimises solar heat gain in summer and bolsters insulation in winter. Moreover, its reflective properties contribute to the building’s overall uValue, making it an ideal choice for maximising energy performance in retrofit and new build projects.

    Features and Benefits:

    • Ideal for floors, walls and roofs
    • Can be used in both new and retrofit projects
    • Water and vapour-proof with foil radiant barrier
    • Creates an ‘airtight’ layer suitable for the entire building envelope
