Vertical Sliding Sash windows
















UPVC vertical sliding sash windows have been developed to replace the traditional wooden sash windows. uPVC require less maintenance and provide a stylish look to your property. Our vertical sliding sash windows also have a tilt-in facility for easy cleaning.


You can also choose from an attractive ‘ovolo’ shaped bead to compliment the outer frame and sash profile. Security has been enhanced through the combination of internal glazing and claw interlock between the two sliding sections. The window locks and sash hooks can be matched in white, gold or chrome finish.


Our timber vertical sliding sash windows are available in hardwood or paint finishes. The features are similar to that of the uPVC windows


Our windows are easy to operate and can be tilted inwards to enable outer surface to be cleaned. We can also provide secure ventilation through optional slender trickle vents fitted into the head of the outer frame.

Tilt & Turn windows






















There may be occasions where larger openings are required or your window needs to open in rather than out, especially for easy to clean purposes.

Tilt and Turn windows do just that, and are often used on modern day apartments or housing blocks.

Openings up to 1 metre wide by 2 metres high can be achieved because the cleverly designed hardware system has a number of fixings all round the window. This mechanism can also incorporate a restrictor facility which can limit the window opening where safety is a consideration..

As an added feature, before fully opening the window, the hinge mechanism will hold the sash in at the bottom whilst tilting inwards at the top, enabling maximum ventilation without the window being fully open.

We can also provide Pivot windows which can also open inwards.  These products are ideal for flats and housing blocks
