Horizontal sliding units
Storm’s Horizontal Sliding Units are ideal for casement windows that require regular ventilation.
Installed into the reveals, this unobtrusive system has minimal impact on the primary windows, whilst maintaining full functionality.
All secondary glazing site lines will be matched up with your existing mullions to ensure that your windows retain their period features without being compromised by secondary glazing - a priority when preserving the character of your historic property whilst improving the thermal efficiency.
Our slim, lightweight framework can be powder-coated to any RAL or BS number to complement your exisitng decor and provide you with a great-looking result, which is virtually invisible, outside and in.
This style of secondary glazing can be made to fit the exact nature of your primary windows, and can be engineered to facilitate out of true cills and heads and even splayed reveals. Our horizontal sliding panes are easily removable to allow cleaning and maintenance of primary windows.
Our secondary glazed units are available in an extensive range of RAL or BS colours, can be filmed with a variety of different films from UV to Privacy and our replacement ironmongery also comes in a range of finishes. We also offer two different types of glass. For more information please see our Finishing Touches section.more info
