NRG Glass

All of our secondary glazing is made to measure to match the primary window exactly, including powder coating the frames any colour to seamlessly fit into your home to retain the character of your property. As one of the leading Essex secondary glazing manufacturers and installers, our services are customised to meet your specifications and our products are second to none. We use an efficient sealing mechanism, which is supremely effective in keeping the cold out and the heat in by providing a thermal insulation to your home, office or listed building.

Our typical type of client at NRG GLASS are home owners of listed buildings and property's in conservation areas, these type of property's cannot change their primary windows, so the best way to improve the thermal rating of their windows is to install secondary glazing which is also an excellent sound insulator. Our super slim secondary glazing system is tailor made to your existing windows, we can also powder coat the frames any colour making the secondary glazing virtually impossible to see from the outside and extremely discrete from the inside.

Extensive use is made of air-conditioning in today's busy offices, shops and at home. Installing secondary glazing will help to reduce the energy used in cooling the building and stops cool air escaping out through your windows.

The cavity or gap between an existing primary window and the secondary unit can make a significant difference to the level of noise insulation. Unlike sealed units where the two pieces of glass are rigidly coupled together, the primary and secondary windows act as independent barriers to the transmission of noise. Secondary glazing is an effective method of reducing noise pollution, whether you are looking to guard against noise, road traffic or to retain noise i.e pubs, clubs etc. By increasing the gap, otherwise known as the cavity, between the existing window and the secondary frame, the better the sound proofing becomes.
