Performance and appearance.
Finally in the same sentence.

There are thermally broken steel systems that perform well. There are those that look good. The Artesa was built to do both, without the usual trade-offs between them.

CE certified to EN 14351-1 and PAS 24 security certified, it brings a level of independent verification that architects and developers increasingly require particularly on projects where compliance documentation needs to be watertight alongside the installation itself. Acoustic insulation up to 45dB and U-values down to 1.2 W/m²K handle the thermal and acoustic demands of both urban and rural settings. The ZF100 corrosion-resistant coating ensures it performs in exposed locations over a building’s lifetime without deterioration.

Ultra-slim sightlines keep the frame where it belongs: supporting the glass, not competing with it. Compatible with double and triple glazing, available in clear, frosted, fluted and solar-control options, and finished in any RAL colour with maximum sash dimensions of 1000mm × 2500mm.
