The HAHN Louvre Window Tairmo was the first louvre window with Uw heat insulation value of up to 0.9 W/m²K. This innovation of the Tairmo system is based on aluminium extrusions with large thermal breaks, insulated cores to the profiles and the exclusive use of triple glazing utilising ‘warm edges’ as spacers. Tested and certified for Natural ventilation (EN 14351-1), Smoke ventilation (EN 12101-2), Ball protection safety (DIN 18032-3), Burglar resistant (DIN EN 1627), Sound insulation (EN ISO 717-1) and Fall protection (DIN 18008-4).
