the new generation of windows in heritage-listed buildings
The new generation of windows in heritage-listed buildings with an overall depth of 82 mm for top thermal insulation, narrow views, integrated weatherboards and a narrow mullion section.
Ingenious construction makes mullion widths of up to 98 mm possible. Straight window frames on the left- and right-hand sides and on top simplify reconstruction true to the original. An authentic window reconstruction is achieved through a cavity air flow of 4 mm and a recessed locking point.
