The Challenge
Alasdair needed an effective way to improve the insulation of his traditional sash-style windows without replacing the existing frames. The rooms suffered from heat loss, draughts, and was difficult to keep warm during colder months. Like many homeowners with older or heritage windows, he wanted a solution that would:
- Improve thermal performance
- Maintain the look of the original windows
- Allow easy access for ventilation and cleaning
- Fit precisely to a non-standard window size
A bespoke secondary glazing system was the ideal option.
The Solution: Bespoke Glass Balanced Vertical Sliding Secondary Glazing
After discussing the requirements with Omega Build, Alasdair chose our Balanced Vertical Slider Secondary Glazing Unit — a high-quality aluminium system with smooth counterbalanced sliding action. This type of glazing is designed specifically for sash windows and tall openings where regular hinged panels are not suitable.
Key features of the chosen system include:
- Smooth, counterbalanced vertical sliding operation
- Bespoke manufacturing for an exact made-to-measure fit
- High-performance glass for better insulation and noise reduction
- Slim aluminium frame that blends seamlessly with existing windows
- Easy access to the primary window for cleaning or ventilation
The custom-made unit was manufactured to the precise sizes provided and delivered ready for installation. He used our Measuring up for secondary glazing guide

- Easy operation thanks to the balanced vertical slider mechanism
- Primary window remains accessible for cleaning
