Our story

Why isn’t curtain wall framing improving?

That was the question we started asking ourselves in 2008. Glazing technology improved dramatically in recent decades, but when we looked at framing technology, we still saw the same conventional, highly conductive aluminum systems we’ve been using since the 1950s. With envelope performance metrics and carbon targets driving more construction projects, every thermal bridge matters. And aluminum-framed curtain wall systems (and balcony slabs, but one thing at a time), struggle to deliver the thermal performance today’s building codes demand.

We found a better way

Rethinking aluminum-framed curtain wall systems could never come from “inside the box,” it could only come from a Canadian manufacturer with experience in innovative materials – materials time-tested for endurance in some of the world’s harshest climates. So we focused our research and development on TP-FRP (AKA “fibreglass”), a low-carbon material with thermal performance characteristics unmatched by any metal.

Bringing fibreglass-framed curtain wall systems to the world

In 2013, after five years of R&D, we commercially launched the world’s highest thermally performing curtain wall system at Greenbuild in Philadelphia. Leveraging the latest advances in pultrusion and glazing technology, we set a new bar for new materials in the industry.

Today, GlasCurtain continues to manufacture the most advanced curtain wall systems in the world. Featuring industry-leading thermal performance, impressive strength, incredible tactile warmth, and reduced carbon footprint, Thermaframe is the sustainable choice for architects seeking to build a better tomorrow.

GlasCurtain believes in a better tomorrow. Together, we’re building a future that’s more sustainable, more resilient, more comfortable, and more beautiful.
