To ensure structures perform as designed, every detail counts. Tyvek FlexWrap tapes are solutions from DuPont, created to maximise the functionality of breather membranes and air and vapour control layers (AVCLs) by adapting to the most challenging penetrations in the building envelope. In addition to Tyvek FlexWrap NF, the company has launched what it says is an easier to fit and attractively priced version: Tyvek FlexWrap EZ, which comes in a narrower width of 60mm and a roll length of 10m.
A concertina style design means that Tyvek FlexWrap tape can shape itself to create a highly effective seal for the membrane around any irregular shape or complex joint, whether around services, piping or cabling, into the corners and junctions of an aperture, around doorways, rafters, joists, etc.
Supplied in ready to use rolls, Tyvek FlexWrap EZ is compatible with most building materials, while being quicker to fit than many standard tapes. Premium butyl adhesive with a Tyvek top-sheet ensures that insulation, timber frames, interior cladding etc., are properly protected from air and moisture ingress and so function to capacity. UV resistant, prior to covering, it also allows for structural movements and performs over a wide temperature range.
