Innovative, entry level wood aluminium window (Available as Design, Design Plus, Design S-line and S-line Plus) combines high quality design, good energy efficiency, high level of security and extraordinary comfort. The very slim wood elevation increases the glazing surface and improves the thermal protection value of the window whilst the outer skin made of RAL coloured aluminium provides excellent weathering resistance reducing maintenance to a minimum.

KATZBECK sources all its timber from sustainable, FSC certified forests and uses environmentally friendly finishes.

With Uw from 0.71 W/m²K (Design Plus/S-line Plus) the DESIGN range is suitable for a wide range
of low energy projects from AECB Silver to Passivhaus schemes.
