Why Choose SILEX Fiberglass Windows?

Why Choose SILEX Fiberglass Windows?

Engineered to provide the slim profiles of aluminum with the thermal efficiency of wood, fiberglass is the only material that matches the expansion and contraction of the glass itself.

Thermal Harmony

Fiberglass expands and contracts at nearly the identical rate as the glass it holds. This eliminates the primary cause of seal failure and air leakage, ensuring a permanent, airtight seal even when the temperature drops 30 degrees overnight.

Supports 31 mm (1-7/16") IGU for maximum acoustic and thermal performance

Co-efficient identical to glass (eliminates frame-to-glass stress)

Zero corrosion risk

Strength-to-Weight Ratio

Pultruded fiberglass is stronger than steel yet as insulating as wood. This allows for massive spans of glass and slim profiles without the "bulky" look of thermally-enhanced aluminum systems.

Design Pressure (DP): Rated for DP 50–70

U-Factor Excellence: Values as low as 0.26 – 0.29 (Imperial) with triple-pane glazing

Superior Air & Water Infiltration Resistance

Engineering the Invisible: Windows Built for the Canadian Climate

Stick-Built Curtain Wall

Components installed piece-by-piece on-site. Cost-effective for low-to-mid-rise projects with custom geometry.

Unitized Curtain Wall

Factory-assembled panels delivered ready to hang. Faster install, tighter quality control — ideal for high-rise.

Structural Silicone Glazed (SSG)

Frameless exterior appearance — glass is bonded to the frame with structural silicone for sleek, monolithic facades.

Window Wall Hybrid

Slab-to-slab system that integrates with floor edges — a cost-effective curtain wall alternative for condo towers.

Clear explanations to help you understand how we work and what to expect.

What is the primary advantage of a fiberglass curtain wall over traditional aluminum?

The most significant technical advantage is thermal conductivity. Fiberglass is approximately 500 times less conductive than aluminum. In the extreme climate of Ontario and Eastern Canada, an aluminum frame acts as a thermal bridge, pulling heat out of the building. Because the VisionPlus® fiberglass frame is a natural insulator, the frame itself acts as a massive thermal barrier, drastically improving energy efficiency and lowering operational costs.
