Low-E Glass Options
Argon Gas Filling
Warm Edge Spacer Technology
Insulated glass units incorporate a non-metal, structural foam warm edge spacer designed to improve thermal performance. The advanced dual-seal system combines a primary adhesive seal with a secondary moisture-resistant barrier, helping protect against air and vapour infiltration. Engineered for durability, the system performs reliably across extreme temperatures while resisting humidity and UV exposure.
Internal Air Chambers
Multi-chambered profiles improve insulation, reduce noise, and enhance overall strength and energy efficiency.
Double & Triple-Pane Glass Units
Our windows are available with double or triple-pane insulated glass units, engineered for enhanced thermal performance. Multiple layers of glass, combined with advanced sealing, create an effective barrier against heat transfer, humidity, and outside noise—delivering improved comfort and energy efficiency year-round.
Brickmold
A factory-integrated exterior trim that provides a clean, finished appearance while sealing the interface between the window and adjacent building materials such as brick, stone, siding, or stucco. Available in a variety of profiles and sizes, with custom configurations to accommodate shaped openings.
Interior Finishes
High-quality vinyl casings provide a clean, architectural finish while ensuring long-term durability. Engineered to resist chipping, fading, and moisture, they maintain their appearance over time.
