Questions & Answers


What tape should be used with SuperFOIL SFTV?


To ensure a consistant air-tight seal, 100mm wide foil tape should be used. We recommend SuperFOIL Superior Tape for it's high strength and enhanced adhesive which allows it to be used even in cold weather.


What size Staples do I need to fix SuperFOIL SFTV?


We recommend using a minimum 14mm staples for use with SuperFOIL SFTV. The staples should be adequate size to hold the SuperFOIL in place until your battens are fitted forming the permanent fixing.


What size Battens should I use with SuperFOIL SFTV?


As SuperFOIL SFTV is a thermal vapour barrier membrane battens are not required. However your thermal performance will be improved if you provide a clear cavity to one or both sides of the SFTV.
