New Tyvek® FlexWrap EZ tape helps optimise airtightness and seal awkward areas

New, quick and easy to install Tyvek® FlexWrap EZ makes an airtight seal around difficult penetrations and irregular shapes, and is narrower than Tyvek® FlexWrap NF


To ensure structures perform as designed, every detail counts. Tyvek® FlexWrap tapes are ingenious 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, now there’s an even easier to fit and attractively priced version of this highly valued tape: Tyvek® FlexWrap EZ, which comes in a narrower width of 60mm and a roll length of 10m.

A clever 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 simple and straightforward to apply and compatible with most building materials, while being quicker to fit than many standard tapes. Premium butyl adhesive with a Tyvek® top-sheet, it offers all the long term dependability you would expect of a DuPont product, ensuring 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.

Don’t let the headache of properly sealing your project drive you around the bend…for complete peace of mind install expandable, curve-able Tyvek® FlexWrap EZ as part of a proven, optimal system.
