Secondary Glazing FAQs 

Secondary glazing consists of two or more glass window panes that are separated by a space. This space reduces heat transfer across the part of the building. Secondary glazing is a cost effective and efficient way of improving the heat retention, sound reduction and security of a window. This type of glazing is becoming increasingly popular for all modern homes. 
 
Secondary glazing is a slim, lightweight aluminium powder coated frame, with either soundproof or insulated glass. The secondary glazing is installed behind the original window, which can be horizontal and vretical sliding, hinged or lift out design. 
 
Please contact us via webform or telephone with any questions and details about your project. For example, current windows, problems, potential benefits and type of window required. We will then arrange an onsite visit to measure your window area and provide a free quote. 
 
Once happy with your product, we will arrange an installation time that suits you, preferably between 9am and 2pm. Depending on the amount of windows, it typically takes a few hours to a day to install multiple windows. 
 
Our typical lead times are two to eight weeks depending on the amount of windows. We ensure your products are perfect before installation. 
 
Whilst not completely soundproof, secondary glazing does provide a significant reduction in noise. The larger air space created by secondary glazing decouples the movement of the inner and outer glass, which means they act as separate barriers, thereby reducing resonance and performing better than standard sealed unit double glazing. 
 
Secondary glazing is a highly cost-effective solution to insulating and soundproofing your windows; that is what makes it so popular. If you’re looking for quality secondary glazing in Colchester, Essex, contact NRG Glass for the most effective secondary glazing you can find.
