  • Authentic heritage appearance

The aesthetics of our Vertical Sliding Sash Window are second to none and it has all the features of a traditional box sash timber window. It’s why it is commonly passed for use in heritage and conservation areas with no further information required.

For projects where the authenticity needs to move up a level, there is a mechanically jointed option that delivers all the features of the standard version, but features mechanically jointed frames and sashes instead of the standard mitred weld.

And to further enhance its versatility, a new ultra-slim meeting rail option will soon be available. At just 37mm the new, slimmer meeting rail faithfully replicates the appearance of a traditional sash window and adds even greater heritage authenticity.

Behind its heritage looks, Epwin Window Systems’ Vertical Sliding Sash Window is a very modern window. Outstanding thermal efficiency and security are just the start. Smooth operating balance mechanisms make it a pleasure to use. There are travel stops for child safety. And for easy cleaning, both sashes tilt inwards. It means the Epwin Window Systems Vertical Sliding Sash Window offers the best of all worlds.
