uPVC Sliding Sash Windows – Character and Style Retained

Design for the Vertical Slider uPVC window option, was made after extensive consultation with conservation bodies and housing associations.

Traditional timber aesthetics can be replicated by combining sight – lines of the 42mm,52mm or 62mm heritage sashes with the deep 81mm heritage bottom rail. The 10 mm incrementally stepped sash profiles allow for equal glazing sight-lines to run from top to bottom sash creating an aesthetically pleasing finished product.

Normally associated with this style of window are jambs, rattles and draughts but all that has been eliminated with modern design and materials whilst retaining the charm and style of your character home with a traditional range of colours that are made to last. No peeling or repainting required with our Rehau frames. Planitherm glass fitted as standard.


The REHAU system is extruded from RAU-PVC 1406 (unplasticised, modified polyvinyl chlorides) which is vigorously tested to temperatures as low as -40˚ and up to +60˚ without losing any quality or durability. With our extensive range of colours, styles, hardware options, locks & gearing you can guarantee that not only will you get a product that can suit every home but is extremely durable and will last for years to come making our PVCu products a cut above the rest!
