Energy Efficiency. Climate Control. Year-Round Comfort.
Insulated Glass Units (IGUs) are the industry standard for commercial windows, doors, and façades offering high thermal performance, condensation resistance, and energy cost savings. Designed with two or more glass panes separated by an air or gas-filled spacer, IGUs are essential for climate control in Ottawa’s demanding four-season environment. At Centennial Glass, we fabricate and install custom IGUs built to your specifications for both new construction and retrofit projects.
Planning a window or curtain wall system that needs thermal performance?
Built for Canadian Climates
IGUs help buildings maintain interior comfort and reduce energy load year-round keeping heat in during winter and out in the summer. They’re ideal for:
- Commercial and institutional windows
- Storefront systems and curtain walls
- Entry doors and vestibules
- Condos, apartments, and high-rise glazing
- Healthcare and educational facilities
We supply single-seal or dual-seal IGUs with argon gas, Low-E coatings, tinted, or laminated layers to meet code and energy performance goals.
Key Benefits
- Dual or Triple Pane Units
- Thermal & Sound Efficiency
- Built for Year-Round Comfort
IGUs also provide sound dampening and UV protection when specified with performance coatings or interlayers making them a functional and aesthetic upgrade in any commercial building envelope.
Custom Fabrication & Professional Installation
Centennial’s insulated glass units are fabricated locally and installed by trained commercial glaziers. Our IGU services include:
- Custom sizing and thicknesses
- Warm-edge or thermally broken spacer bars
- Low-E coatings (soft coat or hard coat)
- Argon or krypton gas fill options
- Laminated or tempered glass pairings for code compliance
IGUs are commonly used in window replacement projects, curtain wall systems, or combined with spandrel glass for a seamless architectural finish.
