Thermal Comfort. Energy Savings. Standard for Modern Performance.
Double pane glass, also known as dual-glazed or dual-pane, is the industry standard for energy-efficient commercial glazing. Constructed with two glass panes separated by a sealed air or gas-filled spacer, it provides superior insulation, noise reduction, and comfort. At Centennial Glass, we fabricate and install custom double pane glass units for new builds, retrofits, and full façade systems across Ottawa.
Upgrading your glass for better comfort and lower costs?

The Go-To Glass for Energy-Efficient Spaces
Double pane glass improves building envelope performance by reducing heat loss in winter and solar gain in summer. It’s ideal for:
- Commercial windows and storefronts
- Curtain walls and window walls
- Multi-unit residential buildings and condos
- Office towers, healthcare, and education facilities
- Energy retrofit and sustainability upgrades
Available with argon gas, Low-E coatings, tints, or laminated layers, double pane IGUs balance affordability with high thermal performance.
