Benefits
Thermal Efficiency
Our secondary glazing system doesn’t just block draughts—it significantly boosts your home’s thermal performance. In fact, thermal imaging tests have shown a 5°C improvement in internal surface temperatures after installation.
The image here clearly demonstrates this effect: areas that were previously cold and heat-leaking are now visibly warmer, thanks to our system’s ability to create an insulating air gap and fully seal the window frame, edges, and glass.
This enhanced thermal efficiency not only improves comfort but also helps to reduce heating costs—making your home warmer in winter and more energy-efficient all year round.
Unbeatable Noise Reduction
One of our customers, an architect living on a busy street in Edinburgh, kindly put our CSG System to the test. Having previously used Perspex secondary glazing, he measured the sound levels before and after installing our glass system. The results showed a clear improvement — around a 10 dB reduction, which equates to roughly 50% less perceived noise. That means our secondary glazing turned the constant roar of city traffic into a far more manageable background murmur, making his home noticeably quieter and more comfortable.
We are confident that our secondary glazing system provides the best noise reduction any secondary glazing system that does not require planning permission and still allows shutters to work as normal can offer.
Draught Proofing
Our secondary glazing system offers market-leading draught proofing—eliminating draughts entirely. Unlike many other systems that mount flat onto the glass, ours is uniquely designed to hinge from the staff bead. This critical design feature allows us to seal not just the glass, but the entire window, including the edges and frame.
The result is a dramatically more effective barrier against draughts, helping to improve thermal comfort and energy efficiency in your home. Better still, our system is fully compatible with functioning shutters and typically does not require planning permission, making it the most versatile and effective draught-proofing secondary glazing solution on the market.
