Named for the Latin word for silica, Silex is a Canadian manufacturer dedicated to the intersection of material science and architectural longevity. They specialize in high-performance window and door systems crafted from pultruded fiberglass—a material rooted in the same mineral foundation as the glazing it holds.
Why Meteek choses Silex
We chose Silex because they address the most persistent failure point in high-performance fenestration: differential thermal expansion. In the extreme temperature swings of the Lake Superior region, frames and glass that expand at different rates eventually compromise their seals; Silex frames move in unison with the glazing, preserving the building envelope’s integrity for decades.
Application
The engineering win lies in the pultrusion process, which creates a composite ten times stiffer than vinyl and naturally non-conductive, effectively eliminating thermal bridging without the need for complex thermal breaks. Because the fiberglass frame and the glass share a nearly identical thermal expansion coefficient, the unit functions as a unified system, maintaining a permanent airtight seal even under intense structural and thermal stress. These systems are best suited for contemporary projects requiring massive glass spans and slim profiles, or for high-exposure residential and commercial sites where aluminum would fail thermally and vinyl would lack the necessary structural rigidity.
