Sash Windows Logo

The Bygone Collection Sash Windows

Our sash windows combine attention to detail and exceptional build quality, with an unprecedented 12 year guarantee. Exclusively available from sash window specialists, Masterframe; this quintessential sash window is as perfect for authentic period conservation and restoration, as it is for thermally efficient new build period reproductions.


Bygone Symphony Sash Windows Logo

Now available with FINEO vacuum insulated glazing and a 1.2U-value.

Patented Timberweld® butt-jointed construction, exclusive super-slim mid-rail, deep timber-like frame cill, and run-through sash horns make this range virtually indistinguishable from original timber sash windows.


Bygone Harmony Sash Windows Logo

Patented Timberweld® butt jointed construction and continuous sash horns already give this window some serious timber aesthetics, but why not add a super-slim 39mm mid-rail.

Bygone Melody Sash Windows Logo

Complemented by the same frame and sash designs found on the Harmony and Symphony range, exclusive Bygone 12 year guarantee and A rating, the Melody sash window offers outstanding value.
