SILEX awning windows are engineered for high performance residential and commercial applications where thermal efficiency, airtightness, and durability are critical. Manufactured using pultruded fiberglass profiles, these windows offer exceptional dimensional stability, reliable weather resistance, and long-term performance in harsh Canadian climates.
Manufactured with pultruded fiberglass frames, their tight compression seal ensures excellent air and water performance, improving indoor comfort and reducing energy loss.
Fully insulated pultruded fibreglass profiles deliver exceptional strength, dimensional stability, and thermal performance while minimizing thermal bridging in demanding climates.
An insulated triple-seal system enhances air and water tightness while supporting superior thermal continuity and long-term weather resistance.
Designed for controlled ventilation and excellent resistance to wind-driven rain, making it ideal for exposed environments and challenging weather conditions.
At SILEX, we custom engineer windows to match your exact specifications. From elegant bay and bow windows to uniquely shaped architectural designs, we deliver precision crafted solutions tailored to your needs. Get your quote today.
