Argon usually turns up the same way for homeowners. You are comparing two or three quotes, and the spec sheets each list something like argon-filled, Low-E coating, warm-edge spacer. It reads like a feature you are meant to recognize, and it is fair to wonder whether it is a real upgrade or a line item that just sounds technical.
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.
