Energy Efficient Sliding Sash Windows


Our uPVC vertical slider allows you to benefit from the classical style of the Edwardian/Victorian sliding sash window with all the modern day benefits of thermal efficiency and security of a uPVC sliding sash window. In a nutshell with our range of vertical sliding windows, which includes an A rated sliding sash, you no longer need to suffer swollen/warped wooden sashes, arduous maintenance, poor sound proofing or draughts. 
Our new energy efficient, A rated vertical slider has been designed to deliver the latest in thermal efficiency and security. It will meet the demands of any project whether it is as replacement vertical sliders or for new builds. The ovolo design detail coupled with the options of decorative horns, surfaced mounted Georgian bar and deep bottom rail gives an authentic appearance. With triple brush seals and hardware ordered to the weight of each window, they provide outstanding weather proofing and security. Both sashes tilt in as well as slide, enabling ease of cleaning and maintenance.
