Secondary Glazing Suffolk 

NRG GLASS is a family-run business committed to providing cost-effective and energy-efficient secondary glazing in Suffolk. 13,000 listed buildings are home to this rural county, so we understand the need to keep that historic charm without damage. 
Conservation areas have stricter planning permission guidelines, even when installing something as simple as a window. Instead of removing the original ones, secondary glazing works alongside them by providing protection from the cold while keeping the character of the property. With reduced condensation, our windows also offer you a better view. 
Don’t just envision the future of your secondary glazing in Suffolk, make it happen with NRG GLASS. Your modernised windows are just one click away! Contact us today to look forward to easy planning consent and warmer winters.

Our Testimonials 

Very neat system, hardly noticeable in our old listed cottage. 
M Rose, Suffolk 
The secondary glazing has considerably reduced the noise at the front of our property and is very discreetly fitted inside our period box sash windows. Recommended them to our neighbours. 
Mr Sutton, Suffolk 
Hello Geoff & Rob 
Just a quick note to thank you for the excellent secondary glazing. 
The whole process from initial contact, to onsite visit, quotation, fabrication and installation worked like a dream. And all in less than 5 weeks. 
Very impressed.
