Project Description

PVCu Sash Windows

Vertical sliding sash windows from Window Warehouse offer a traditional looking window for period properties with the low maintenance, energy efficient benefits of a PVCu window.

The detailing of the profiles, Mortice and Tenon appearance key joints, optional run-through sash horns and astragal Georgian bar in our VS sash windows create an authentic look. This is enhanced by a wide range of heritage colours. The VS windows feature tilting upper and lower sashes making them easy to clean. Low sightline beads and glazing gaskets maximise the glass area to let in more light.

  • Low maintenance traditional style PVC-U frames.
  • Equal top and bottom sash sight lines and fully featured sculptured frames.
  • A choice of Georgian bar designs.
  • Optional decorative and run through sash horns. Other options include – trickle vents, a deep bottom rail for period styling.
  • Different sill sizes are available: 154mm (standard), 150mm, 180mm and 225mm. Sill jointers offer a professional detailing finish.
  • BSI Kitemarked. CE Marked. Guaranteed for 10 Years

Energy Efficiency

One of the main reasons your customers will be looking to replace their sliding sash windows will be the energy efficiency of their existing windows. They can be draughty, warped or not double glazed.

Our sliding sash windows are certified up to ‘A’ rated for energy efficiency available with our efficient glazing options and PVCu frames. Our sliding sash windows are also highly insulated to significantly reduce your customer’s heating bills.

PVCu sliding sash window hardware options

It is important to get the right finishing for your customer’s windows to ensure you are creating the style they are looking for. This is why we supply a wide range of traditional handles and hinges including a loop handle.

With sliding sash windows, it will be especially important to create a period or traditional look and feel with the correct handles and locks. We have a wide range to choose from so you and your customers can get the finish they really want.


Traditionally, sliding sash windows have been considered less secure than other types of window but with Window Warehouse, this simply isn’t the case.

We have invested in a variety of locking and security options, including an optional anti-jemmy security bar which can be specified, as well as additional security locking features including high security locking. These high quality security features mean you and your customers can feel confident when choosing sliding sash windows from us.
