Calgary's climate swings from +35C summers to -40C winters, with chinook winds that can shift temperatures 20 degrees in hours. Valordek vinyl decking is tested across the full range. Manufactured in Surrey, BC, with an authorized dealer in Calgary. Certified to exceed CGSB-37.54 waterproofing standards. 11 colours. Starting at $3.74 per square foot.
Calgary experiences some of the most dramatic temperature swings in North America. Summer highs exceed 30C with intense UV exposure at 1,048 metres elevation. Winters regularly hit -30C with wind chill. Chinook events can raise temperatures from -20C to +10C within a single day, creating rapid freeze-thaw cycles that crack rigid deck surfaces.
Valordek vinyl decking membranes are tested from -40C to 80C. The flexible PVC does not crack in extreme cold, does not warp in summer heat, and absorbs the constant expansion-contraction cycles that come with Calgary's chinook climate. No annual sealing, staining, or coating required.
The National Building Code classifies any deck over occupied space as a "roof" that requires waterproofing to CGSB-37.54 standards. Valordek vinyl membranes carry CCMC and Intertek certifications confirming they exceed code 37.54.95.
Calgary's housing stock includes everything from 1960s bungalows in Brentwood and Dalhousie to new infill developments in Marda Loop and Bridgeland. Condos and townhouses continue to be built across the southeast and northwest, each with balconies that need waterproofing.
The 68mil Fuzzy-Back membrane is the standard choice for residential balconies. It installs with contact adhesive (VD 0295 / VD 0220) and heat-welded seams that create a continuous waterproof surface. No board gaps, no screw holes, no expansion joints for snow melt to exploit.
Spring snowmelt is a major water intrusion risk in Calgary. Snow accumulates on balconies through the winter, then melts rapidly during chinook events or in spring. Water pools on flat surfaces and finds every gap in non-membrane deck systems. A continuous vinyl membrane eliminates these entry points.
Calgary's downtown and inner-city neighbourhoods are adding rooftop amenity spaces to mixed-use and condo developments. The Beltline, East Village, and Kensington all feature buildings with elevated outdoor spaces that need commercial-grade waterproofing.
The 60mil Smooth-Back membrane is built for rooftop applications. It uses contact adhesive (Sika 2170-R) with PVC flashing on open decks and heat-welded seams. Class A and C fire rated, tested by Intertek. The 15-year waterproofing warranty covers Calgary's extreme conditions.

Calgary's construction season runs from roughly May through October. Contact adhesive requires dry substrate and temperatures above 10C for proper bonding. The city's dry summers provide reliable installation conditions, and the extended daylight hours in June and July allow for full-day installations.
Fall installations through September and into October are possible but must be scheduled around early cold snaps. Your Calgary dealer can advise on timing and connect you with experienced installers.
Snow can be cleared from vinyl decking with a plastic shovel or soft-bristle broom. Do not use metal shovels or ice scrapers directly on the membrane surface. Calcium chloride and similar de-icing products are safe to use on Valordek vinyl membranes.
The membrane remains flexible even at -40C. Unlike rigid deck surfaces, it does not become brittle in extreme cold and will not crack under foot traffic or snow removal.

Yes. Valordek vinyl membranes are rated to -40C. The flexible PVC formulation does not become brittle in extreme cold the way rigid deck surfaces do. The membrane has been tested through freeze-thaw cycles and maintains its waterproofing integrity across Calgary's full temperature range.
No. The PVC membrane is designed to flex with thermal expansion and contraction. Calgary's rapid temperature changes during chinook events do not cause cracking, splitting, or delamination. Heat-welded seams maintain their bond through repeated cycling.
Valordek vinyl membrane starts at $3.74 per square foot for the material. Shipping from our Surrey warehouse to the Calgary dealer is included in dealer pricing. Total installed cost depends on substrate condition, deck size, and project complexity. Contact Us for a quote.
