Outstanding Thermal Performance
Foil-Tec Double delivers a certified R-Value of 1.48 m²K/W in wall applications, providing impressive thermal resistance within a slim, lightweight construction.
Its high-performance reflective design helps reduce heat loss and improve overall building efficiency, making it ideal for both new-build and refurbishment projects.
Installation Recommendations
For best results, we recommend installing Foil-Tec Double with Thermaseal Foil Joining Tape. Properly taping and sealing all joints ensures the product performs effectively as a vapour control layer.
To maximise thermal performance, the reflective surface should face an air cavity, followed by a service cavity and plasterboard on the internal side.
Suitable for Multiple Applications
Foil-Tec Double can be used as a standalone insulation membrane for floor applications and is frequently installed alongside SuperQuilt Multifoil Insulation to further enhance thermal performance throughout the building envelope.
Independently Tested & Certified
Foil-Tec Double has been independently tested and certified through the BDA Kiwa Certificate of Agrément, providing assurance of its quality and performance.
Manufactured in the UK to high standards, it offers a reliable insulation solution for residential, commercial, and renovation projects.
