Services
We are a family business that specialise in the manufacturing and installing of secondary glazing. All the windows are manufactured here in our own workshop, which gives us total control over the quality from manufacturing to installation. If you are unsure what secondary glazing is? It's quite simply the addition of a slim secondary window that fits inside the existing window, which helps in soundproofing and insulating your property.
Part L of the building regulations for replacement double glazed windows set a U value of 2.00. Standard 4mm glass secondary glazing over an average single glazed window achieves a U value of 2.5. Secondary glazing can be fitted to improve thermal insulation as well as eliminating draughts. Secondary glazing can improve the thermal insulation of a window by up to 70%.
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.
Planning Policy Guidance PPG15 recognises that the best way to secure historic buildings is to keep them in active usage and this may involve some adaptation to meet current needs. The rich tapestry of window designs are an important part of the character of a building and must be retained but single glazed frames are a major source of heat loss, provide little protection against noise and offer minimal resistance to burglary.
NRG Glass have the facility to manufacture our aluminium products in any RAL colour, to your individual colour requirements. We use industry standard RAL colours, which are a range of over 200 colours available in gloss, semi-gloss and matt finishes, from approved coatings specialists. The Polyester powdercoat paint is baked onto the aluminium in order to withstand the rigors of all weather conditions and modern living in the UK.

We absolutely loved the secondary glazing service of NRG Glass as it considerably reduce the noise at the front of our house and is discreetly fitted inside of the existing windows. Now we can enjoy peaceful moments in our house throughout the day and night. We are very pleased with the quality of the product and fitting. They truly deserved a big applaud.
