What is Secondary Glazing?
Secondary glazing is the process through which a discreet, internal window is fitted to an existing single or double glazed window to enhance performance. It’s seen as a desirable alternative to double glazing, especially for heritage properties as it allows you to maintain the external character of the structure whilst taking advantage of the benefits created by double glazing.
When you take advantage of Gardinia secondary double glazing, you enjoy all of the benefits that come with an extra layer of insulation over your windows. This cuts down on heat transfer, which means that your home stays warmer in the winter and cooler in the summer. Secondary Glazing also insulates against sound and enhances the security of your property.
Great For Soundproofing Existing Windows
Secondary glazing is a stylish and cost effective way of increasing both acoustic and thermal performance, homeowners install secondary glazing to combat two main issues, acoustic and thermal performance.
Our clients who live near the M62 motorway were so delighted with the difference our secondary glazing made they let us film a short video to demonstrate this to potential future customers.
Secondary Glazing from Gardinia can be installed within all house types, even Grade I and Grade II listed buildings. You will receive an 80% reduction in noise breaching the primary window and up to 65% reduction in heat loss. Secondary glazing is often used in conjunction with single, double, and triple glazed uPVC or timber windows, due to it been discreet, durable and most of all functional.
The installation of secondary glazing within conservation areas is advised by Historic England as the installation does not change the original character of the building.

Reduce noise levels by up to 80%
Secondary glazing’s secret is a sound blocking air cavity that is created which drastically reduces noise, teamed with acoustic glass Granada can make a diesel bus sound like an electric car. To achieve the best acoustic performance we advise, an air cavity of up to 200mm glass to glass and the specification of an acoustic glass.
Increase thermal performance by up to 65%
Draughty windows can make a room feel uncomfortable. Secondary glazing acts as a second barrier to the elements often increasing thermal performance. Not only will you have a naturally warmer home but you will even develop a more economical home, by spending less on your heating bills and keeping warmth locked in. We advise the installation of low-e glass which is designed to reflect heat back into your home and an air cavity no more than 80mm glass to glass.
