Vertical Sliding Windows

An updated design that retains the vintage grace and elegance of traditional vertical sliding windows

Finding a suitable replacement for old vertical sliding windows can be difficult. It doesn’t need to be. Our modernised vertical sliding windows contain many of the trademark finishing touches that you associate with an authentic equivalent - sash horns, tilt buttons, lift hooks, sash locks, ring pulls - only they deliver far greater performance. With or without glazing bars they really look the part, however, there’s no doubting that the beautiful ovolo detailing applied to the glazing bars adds even more character to the design, and they won’t ever need repainting.

Capable of achieving an A+ Window Energy Rating, they will thoroughly insulate your home, aided by the flush gaskets and pile seals to keep out the rain and any draughts. They’re a perfect mix of the past and the present.
