Air & Vapour Barrier Membranes – BC
Air & Vapour Barrier Membranes – BC
An air barrier that keeps working is central to an energy-efficient, durable building, and the BC Energy Step Code has made airtightness a priority on every project. At BC Building Products we supply air barriers, vapour barriers and water-resistive barriers (WRBs) to envelope contractors, framers, builders and developers throughout British Columbia.
Our range covers vapour-permeable and vapour-impermeable membranes, self-adhered and mechanically fastened sheets, liquid-applied barriers, and the tapes and flashings that make the joints airtight. Brands include Henry (Blueskin), Tremco, Soprema, Delta (Dörken), VaproShield, DuPont Tyvek, Resisto, SIGA, 3M, Protecto Wrap and EPRO.

Vapour-permeable membranes
Where the wall needs to dry outward, choose from Tremco ExoAir 210AT (primerless, self-adhered), SOPRASEAL STICK VP, DELTA-VENT SA, DELTA-FASSADE SA, VaproShield WrapShield SA, Resisto VP SA, and DuPont Tyvek CommercialWrap and HomeWrap.
Vapour-impermeable membranes
Henry Blueskin SA is a self-adhered SBS rubberized-asphalt air, vapour and water-resistive barrier, used for full walls or as a penetration and flashing membrane. We also carry SOPRASEAL STICK AVB AT, Soprema 1100T, 3M Air and Vapour Barrier 3015NP, and Protecto Wrap membranes.
Liquid-applied air barriers
For complex geometry, liquid-applied barriers such as Tremco Enviro-Dri and EPRO ECOFLEX-PS give continuous coverage without seams.
Interior vapour barriers and tapes
For the interior side we stock CGSB 10 mil vapour barrier sheeting and EPRO e.shield 110. For airtight joints, use SIGA Wigluv and Rissan tapes, DELTA MULTI-BAND and FLEXX-BAND, and Protecto Wrap Super Stick tape.
