Casement windows are the most popular style of replacement window in the UK – an extremely versatile window that will suit all styles of the home ensuring you can make a real statement. Featuring fixed panes, top opening fanlights and side opening lights, casement windows can be combined to create an almost limitless range of styles. With many additional features such as decorative glass, Georgian bars and run-through sash horns, casement windows can be tailored to your specific requirements and are available in a range of finishes and colours.


Designed to replicate traditional timber box sash windows, the REHAU Heritage window system will provide you with a traditional looking sash window combined with the benefits of uPVC. Superbly engineered and of exceptional quality, sash windows manufactured from the REHAU Heritage system will add real value and style to your home without sacrificing performance. Classic-style hardware and fittings and optional decorative horns replicate the traditional timber sash window to create a stunning finish.  Further attention to detail in the form of a deep bottom rail and optional Georgian bars add to a simply superior uPVC sash window. 


Tilt and turn uPVC windows offer a simple, contemporary, stylish solution to suit modern properties, providing a functional alternative to opening out windows. Tilt and turn windows offer you simplicity and versatility – providing a choice of styles which have the option of the window tilting inwards or being fully opened inwards. This flexibility provides you with secure ventilation and ease of cleaning from within your home, along with making tilt and turn windows the ideal solution where there is restricted space outside making outward opening a hazard and also provides an effective fire escape.


Bay and bow windows are an elegant and attractive external feature in any property whilst internally creating a sense of space and light. Bay and bow windows are created using casement windows which are connected using a strong, structural bay pole assembly or corner posts (for square bay windows) and as with all REHAU products are available in a range of finishes and colours.
