Why Calgary homeowners need windows rated for extreme temperature swings: Calgary moves from deep winter cold to Chinook warmth and back, sometimes within a single afternoon, and windows built for that constant expansion and contraction hold their seal, insulation, and comfort where ordinary windows loosen, leak, and fog.
Before you buy a sliding patio door in Canada, the decision really comes down to five things: energy performance for our climate, the frame material, the glass package, the security hardware, and the quality of the installation. Get those elements right, and you are more likely to have a door that operates smoothly, limits drafts, and performs reliably over the long term.
DraftLOCK is Canadian Choice Windows & Doors’ window technology designed to support a tighter seal, reduce unwanted air leakage and improve year-round home comfort. Its performance depends on the complete window configuration and proper installation.
Most North York windows in detached homes, semis, and post-war bungalows were installed decades ago. They were not built to the efficiency standards that exist today, and even windows from the 1990s can lose meaningful thermal performance over time.
Two fundamentally different approaches exist for assembling window glass: pre-sealed units made by a dedicated glass manufacturer such as Cardinal Glass, and units assembled in-house by window manufacturers themselves. Neither approach is inherently superior.
Argon gas is a standard feature of modern energy-efficient windows in Canada. It sits between the panes of glass, invisible and inert, and quietly does most of the work of keeping a window from leaking heat. Most homeowners never think about it until they read a spec sheet, hear a sales pitch, or notice condensation forming between the panes.
