Vertical Sliding Sash Window


The Sash window or Counterbalanced Vertical Slider is one of the most common windows that we install. With our take on this classic design it means you benefit from the same great aesthetics, whilst avoiding all the issues associated with centuries old versions. Making your windows low maintenance and energy efficient for your home.

This style of windows allows the top panel to slide down and the bottom panel to slide up working in the same way as your original window.  With our precision measuring of the break line of your original window, the new window will match the old one exactly. So long gone are the rattling, jamming and uncomfortably draughty sash windows.


The frame on this window is 34 mm high and 37 mm width.
