Common questions

What is CSA A440-22?
The Canadian Standards Association harmonized standard for windows and doors. It covers U-factor, air-water-structural performance, and cold-climate suitability. The Crateworks supply network holds CSA A440-22 cert #80224506 on file.
What U-factor can you hit?
U-factor range on file is 0.236 to 0.387 depending on configuration. Triple-pane LowE Argon glazing pulls the U-factor down further; specify the climate-zone target and we will confirm the buildable U-factor at quote.
Aluminum in cold climate — does it work?
Yes. Thermally-broken aluminum decouples the outside metal from the inside metal so heat does not conduct straight through. The PA66 polyamide thermal break is the standard of the industry in modern aluminum fenestration. Casement and tilt-turn configurations carry the tightest compression seals in cold-weather operation.
Do you ship to Canada?
Yes. Source-direct shipping to Canadian provinces on the CSA A440-22 cert. Cross-border tariff and duty are itemized on the quote.
