The new window system has a wood width of only 68 mm. The face width 110 mm in double rebated. Our unique innovation: the fabricator can manufacture a complete window with the 68 mm x 68 mm timber cross-section. Frames, sashes, transoms or mullion - all components can be made in 68 mm. All common opening types and window constructions are possible.
