These certified solutions include doors, screens, and curtain walls that meet BS476 and EN1363 standards. Designed for commercial and public buildings, our systems combine safety with modern architectural requirements.
Steel Thermally Broken Windows
Thermally broken steel windows offer U-values as low as 0.69 W/mK while preserving historical aesthetics. These slim-profile windows suit heritage and high-end residential projects, providing superior thermal performance without compromising design integrity.
