The PURe range features patented polyurethane thermal barriers achieving ultra-low U-values, while the SPW600 system provides versatile solutions for residential and commercial applications.
Curtain Walling
Our curtain wall systems enable creative architectural expression with high structural performance. The SF62 system suits ultra-high-rise projects, while the SCW+ offers thermally enhanced semi-unitised solutions. All systems integrate seamlessly with doors and windows, providing slim sightlines, customisable finishes, and compliance with stringent building regulations.
