Got more questions? Send us your enquiry below

Why is fiberglass better than vinyl or aluminum?

Pultruded fiberglass is 8x stronger than traditional vinyl, allowing for thinner frames and larger, panoramic views without sacrificing structural integrity.

How do SILEX products perform in cold climates?

SILEX systems are designed to exceed Canadian fenestration standards, including the latest National Building Codes and ENERGY STAR® requirements. They offer superior thermal breaks compared to traditional aluminum, preventing "cold spots" even in extensive floor-to-ceiling glass applications.

What is an EPD?

An Environmental Product Declaration (EPD) is a third-party verified document that provides transparent information about a product's environmental impact. SILEX products are EPD verified, making them suitable for Net-Zero and Passive House building standards.

Can SILEX handle custom architectural designs?

Yes. SILEX specializes in complex projects, including custom units for faceted arrangements to accommodate curved or circular building architecture.

Do you offer large "wall of glass" solutions?

Our Large Format Doors and Curtain Wall systems (4500 and 6500 Series by SILEX) are specifically designed for massive, unobstructed glass spans and "walls of glass" while maintaining high structural ratings.
