Alu-clad Triple Glazed Timber Windows

An alu-clad version of 21° PERFORMANCE and ULTRA timber inward opening window ranges is now available. For environmental and maintenance reasons Green Building Store still recommends pure timber windows.  However, alu-clad windows are much in demand among selfbuilders and architects, so Green Building Store has introduced it now as an option for its inward-opening PERFORMANCE and ULTRA windows.

New option from Green Building Store

The new alu-clad range offers an updated contemporary design with narrow installed sightlines with the timber frame designed to be wrapped within external wall insulation. For that reason, it is mainly designed for newbuild projects or deep retrofit, where there is the opportunity to ‘bury’ the frame within external insulation.

Key features

• Visible external sightline: 71mm (opening window)
• Partially exposed timber frame, for wrapping within external insulation
• FSC^® certified timber in redwood & oak
