What Makes Calgary Different

Your windows face extreme conditions that most homeowners underestimate. Here's what matters in our climate.

Extreme Cold

Calgary winters are hard on glass, frames, and seals. Poor-performing windows can lead to cold rooms, condensation, and noticeably higher heating costs during deep cold snaps.

Thermal efficiency critical

Temperature Swings

Chinook winds cause 20°C+ temperature shifts in hours. This extreme stress cracks poor-quality seals and causes condensation between panes. High-quality windows handle thermal shock.

Typical Chinook Temperature Swing

-25°C +10°C

UV & Dry Climate

300+ days of sunshine bleaches frames, causes frame expansion, and stresses seals. Low humidity means moisture doesn't buffer temperature changes. UV-protective coatings extend lifespan 10+ years.

Premium coatings pay for themselves
