Glidevale Protect BarriAir with integrated lap and sealing tapes is a high performance and multi-purpose coated non-woven membrane which forms a highly effective air leakage barrier with vapour control qualities.

The yellow semi-translucent material has a grid printed across the whole surface which promotes simple alignment with timber studs or joists. The new integrated tapes are located on the outer edges of the membrane following the dotted overlap line. On one side the tape is on the upper surface, on the other side the tape is on the lower surface. This layout ensures that the membrane overlap is jointed and sealed by applying the two layers of adhesive to one another, providing a more effective seal than a traditional overlap tape even when joined without an underlaying substrate.

There is an additional benefit in that any mechanical fixings applied through the double layered strips will have reduced air leakage as the adhesive will act as a sealant.

Questions & Answers


Can this be retro fitted over PIR board (between joists) that will be on a ground floor timber suspended?


Provided it is fitted on the warm side of the insulation (innermost side) - I can see no issue as to why you could not do this. 


Can this product be used under slates?


This is a high perfomance vapour barrier designed to be used on the warm side of the roof, you'd be best looking at a breather membrane like the following which is designed to be used as the outermost layer before tiles or slates - https://www.insulationsuperstore.co.uk/product/protect-tf200-thermo-insulating-breather-membrane-15m-x-50m-roll.html
