OUR WINDOWS
Engineered for Canadian Climates
High-performance windows designed to stay airtight, energy-efficient, and durable year after year. Built with advanced frames, insulated glass, and precision manufacturing for comfort in every season.
All window styles feature advanced multi-chamber uPVC profiles designed to improve structural strength, energy efficiency, and sound insulation while reducing the risk of frame warping over time. Reinforcement options are available for both single windows and combination window systems, providing added stability for larger openings. Slimmer frame profiles allow for more natural light and increased glass surface, improving thermal performance and overall home comfort. Our uPVC window frames are manufactured with walls up to 30% thicker than the industry average, providing the strength required to support triple-pane glass and large window units. For added security, all windows are glazed from the interior and include hidden drainage channels along with a heavy-duty mullion interlock system designed for long-term durability and reliable weather protection.
UPVC WINDOWS – WHY THEY ARE PREFERABLE FOR HOMEOWNERS

UPVC (unplasticized polyvinyl chloride) windows are durable, energy-efficient, and low-maintenance. Unlike traditional PVC, UPVC contains no plasticizers or harmful chemicals, making it safe, strong, and odor-free.
Key features of high-tech UPVC windows:
-
Precision Engineering: Ensures a snug fit and smooth operation.
-
Multi-Chamber Profiles: Improve insulation, soundproofing, and structural strength.
-
Advanced Sealing: Airtight fusion-welded or reinforced corners help prevent drafts and water leaks.
-
High-Performance Glass: Low-E coatings, gas fills, and laminated glass improve energy efficiency, reduce noise, and increase safety.
-
Customizable Design: Options for color, style, hardware, and glazing to suit any home.
High-tech UPVC windows are energy-efficient, durable, eco-friendly, and fully recyclable.

ENERGY STAR® Climate Zones in Canada
Canada is divided into several ENERGY STAR® climate zones to ensure that windows, doors, and skylights are tested and rated according to the environmental conditions where they are installed.
Because Canada experiences a wide range of climates—from mild coastal temperatures to extremely cold northern regions—ENERGY STAR® performance requirements vary by climate zone.
This system helps homeowners select energy-efficient windows and doors designed for their specific climate conditions.
Climate Zone Classification
ENERGY STAR® Canada defines three main climate zones for residential windows and doors:
Zone 1 – Mild Climate
Includes regions with moderate winters and milder temperature conditions.
Zone 2 – Cold Climate
Includes most populated regions of Canada where winters are cold and energy-efficient insulation is essential.
Zone 3 – Very Cold Climate
Includes northern regions where extreme winter temperatures require the highest level of insulation performance.
Quebec and Montreal Climate Zone
Homes located in Quebec, including Montreal, fall into ENERGY STAR® Zone 2 (Cold Climate).
For this zone, windows and doors must meet strict requirements for:
-
Low U-Factor values
-
High energy performance ratings
-
Reduced air leakage
-
Improved thermal insulation
These requirements help maintain indoor comfort while reducing heating costs during long winter seasons.
Why ENERGY STAR® Windows Matter in Canada
Installing ENERGY STAR® certified windows and doors can provide several benefits:
-
Lower heating and cooling costs
-
Improved indoor comfort during winter and summer
-
Reduced drafts and air infiltration
-
Lower environmental impact and energy consumption
High-performance windows are especially important in Canadian climates, where heating costs represent a significant portion of household energy use.
