Sash Windows

Marvin Architectural Traditional Weighted Sash Windows


Marvin Architectural’s Traditional Weighted Sash Windows come with the best technology in the industry in terms of superior insulation and meet heritage requirements for conservation and listed buildings throughout the UK.

The options for bespoke profiles, hardware, sash horns and interior architrave and casings mean the window can be emphasised as a beautiful visual feature within the room and with historical accuracy on the outside.

The authentic look of the window is confirmed by the glazing bar design on the glass – a handcrafted, profiled bar – specifically designed to reflect the original design on windows built 250 years ago. The fine frames of the window ensure that no bulky outlines result when installed into existing openings and there is minimal disruption to interior plaster work or wallpaper.
