Secondary Glazing Chelmsford 

Despite being founded in 2010, NRG GLASS combines the experience of father and son Geoff and Rob, totalling to 60 years of installing secondary glazing in Chelmsford. We manufacture all our windows in our own factory and customise them to your measurements to ensure a five-star-worthy service. 
 
Although being a relatively new city, did you know it has one of the highest amounts of listed buildings? In fact, there are over 20,000 of them! With that in mind, planning permission can become a hassle, but NRG GLASS provides a bespoke solution with secondary glazing in Chelmsford. 
 
The city values its history in stores and restaurants across the city, and with that comes the responsibility of protecting its conservation areas. Keep the charm of your original windows while improving insulation. Contact us today for your cost-effective and energy-efficient journey.
