Puro Passive windows are an upgraded version of the Puro system. This new window includes a thick layer of insulation within its frame, sandwiched between external aluminum and internal engineered (laminated) timber.

This comprehensive construction creates a window with exceptional U-values with PassivHaus certification.


The external aluminium is mechanically welded at its corners creating a completely seamless facade with no visible joints. The internal timber is machine profiled with square edges for contemporary aesthetics.
