TRADITIONAL LOOK, MODERN FLUSH SASH

Flush sash windows are the latest exciting development from Mint Trade Frames, combining the realism of traditional pre-1932 timber windows with modern thermal efficiency. You can choose our 70mm casement flush sash or the new 80mm Resurgence system, which both have special seals to keep out drafts and bad weather while looking great.

MODERN FLUSH SASH WITH TRADITIONAL STYLE

Resurgence is the UK’s first uPVC double-rebated flush sash window, ideal for both modern and character properties. When finished in woodgrain foil, it closely resembles traditional timber, with “timber”-welded-look joints and realistic interior lamination. This system, along with tilt and turn windows, offers the style of wood while providing the benefits of secure, energy-efficient, low-maintenance windows and doors.
