Sash Windows

Sash windows have been a much-admired and distinctive feature of many British homes for centuries.

sash windowsToday many homeowners still love the stylish look of these windows – whether they live in a Georgian, Victorian or Edwardian-style property or a house with a more modern look.

Coastline Windows can combine the beautifully sculptured frame of a traditional Sash window with modern materials which make them low maintenance.

Our uPVC windows will not need tricky and time-consuming repainting.  This modern twist on the traditional vertical sliding sash window won’t rot, warp or rattle and it will keep its colour and shape year after year.

Importantly, and giving them a great advantage over the charming but high maintenance traditional timber sash windows, our vertical sliders also tilt making them easy to clean and giving easy ventilation options.

These windows make a great solution if you are undertaking a full period home renovation project and need to replace old wooden sliding windows.

Like all our energy rated windows, these vertical sliders are the UK’s most energy efficient windows under the British Fenestration Rating Council scheme. Whichever one you choose – A, B or C rating – they are all eligible to carry the ‘Energy Saving Recommended’ tag.

High security, advanced weather-resistance and great energy-saving performance are all key advantages you can enjoy when you install our sliding sash windows.

We fit all our windows with the industry-leading 8-point locking system with a corner drive design which allows more shootbolt contact and penetration for increased security. The shootbolt locking system also takes the pressure away from the hinges giving your windows a longer life.

Double glazing units from our ISO 9001-registered manufacturer, Glassline, mean you are making a great choice for performance and quality.

Our vertical sliding Sash windows meet the BSI’s standards for keeping rain and wind out and the advanced glazing technology allows the sun’s power to add to the heating of your home while reflecting heat back into the room off the surface of the glass.

Our choice of finishes – solid colour, white or realistic woodgrain effect – gives you lots of choice and there are also a range of handle styles and colours to add the perfect finishing touch.
