Invisible Efficiency. Indoor Comfort. Energy-Saving Performance.
Low-E (low emissivity) glass is engineered to reflect heat while allowing natural light to pass through improving energy efficiency, reducing glare, and maintaining indoor comfort across all seasons. At Centennial Glass, we supply and install high-performance Low-E glass systems for commercial buildings across Ottawa, helping clients meet energy codes, reduce utility costs, and create more sustainable spaces.
Looking for high-efficiency glass that keeps you cool in summer and warm in winter?
Smart Glass for Smarter Buildings
Low-E glass features an ultra-thin metallic coating applied to the surface or inside layer of insulated glass units (IGUs). This coating reflects infrared heat, reduces solar gain, and blocks harmful UV rays all without affecting visibility. It’s ideal for:
- Office towers and mixed-use buildings
- Educational institutions and healthcare facilities
- Multi-unit residential and condo developments
- Commercial storefronts and curtain walls
- Government and LEED-certified buildings
Used in both new construction and energy retrofits, Low-E glass delivers measurable performance improvements.
Key Benefits
- Energy-Saving Coating
- Blocks Infrared & UV Rays
- Improves HVAC Efficiency
Low-E glass reduces temperature fluctuations, helping reduce heating and cooling loads year-round resulting in lower energy costs and a smaller environmental footprint.
