Welcome to 1st Sash Windows

1st Sash are a UK national company who manufacture, supply and install the very best replacement sash windows available.

Modern technology and craftsmanship means you get precise fitting vertical sliding windows with all the nostalgia of a bygone age, but with none of the maintenance.

Noise, weather and draught are all kept at bay by the full double glazing and weatherseal system.

An in-built tilt facility means the windows can be cleaned in safety from inside the house, so avoiding the need for dangerous ladders and footprints on the flowerbeds!

A traditional look doesn't have to mean traditional security, far from it. Our vertically sliding windows boast the very latest key locks for maximum security, as well as adjustable restrictors and limit stops which limit apertures openings while still permitting ventilation.

Our vertical sliding windows are fully counterbalanced which means the days of sash windows sticking, jamming or slipping are gone forever. Classic style brass catches and decorative horns are used to complete the effect.
