frequently asked questions
Are Protecto Wrap air & vapor barriers permeable or impermeable?
Protecto Wrap offers both non-permeable and vapor-permeable air barrier options. Selecting the correct product depends on climate zone, insulation type, and whether the wall assembly needs to dry to the interior or exterior.
Does Protecto Wrap require primers before installation?
Protecto Wrap’s primer-free lineup does not require primer on clean, dry, frost free substrates down to -28°C. Protecto Wraps asphalt and pure butyl air & vapor barriers do require primers on all surfaces for best practice and optimal adhesion. Primers may be recommended on dusty, porous, or cold surfaces for best practice and optimal adhesion for our full lineup.
What temperatures can Protecto Wrap membranes be installed in?
Many Protecto Wrap membranes are designed for cold-weather installation, such as our primer-free lineup, and can be applied down to -28°C, making them suitable for Canadian jobsite conditions. Pure Butyl solutions offer performance in cold temperatures below 0°C with a cold applied primer. Always confirm temperature limits on the product data sheet.
Can Protecto Wrap air & vapor barriers be used in both commercial and residential projects?
Yes. Protecto Wrap products are widely used in commercial, institutional, multi-family, and residential construction across North America.
How is Protecto Wrap’s SBS adhesive different from other manufacturers?
Can Protecto Wrap membranes be left exposed to UV?
Most Protecto Wrap membranes allow for limited UV exposure during construction, but they are intended to be covered by cladding within the manufacturer’s specified exposure window. However, ProtectoSeal 45 and ProtectoSeal 45 Butyl are UV Resistant and has long term UV exposure ratings.
