Aluminium systems suit projects that need large glass areas, sliding doors or a minimalist look. Thermal and acoustic values come from the Declaration of Performance of the selected system.


Thermally broken aluminium is chosen when you want large openings, slim profiles or a high-traffic building. Check the system and available series from the manufacturer, the Uw value in the DoP, the glass type and the colour (RAL or wood effect).
For projects with an architect or builder we provide technical sheets, DoP and CE, colour samples and alternative quotes for different systems. See what a thermal break is and sliding door types.
