Practical Solution
Enhance Efficiency with Secondary Glazing Options
If you would like to make your single-glazed windows more practical and energy efficient without replacing the entire frame, secondary glazing could be the ideal solution for you. Also known as secondary double glazing, this cost-effective alternative to having double or triple glazing can improve your property’s thermal performance, safety and security, as well as significantly reducing noise levels if you live in a busy area.
Secondary glazing sash windows are also a fantastic option if you live in a conservation area with exceptionally strict regulations, as the extra pane of glass can be fitted discretely on the inside of your property, with the external appearance totally unaffected. We are highly experienced in fitting secondary glazing for listed buildings, with fantastic results.
Heritage Compliance
Upgrade Listed Properties with Secondary Glazing
Secondary glazing for listed buildings is one of the most common applications. Many homeowners enjoy the visual appearance and the character offered by traditional windows but are often unhappy with the acoustic and thermal performance. If you own a property which is Grade I or Grade II Listed, or that is within a conservation area, you may not be permitted to change or upgrade your existing glazing.
In place of a new window frame, secondary double glazing will ensure your home is more comfortable and energy efficient while still adhering to your local authority’s regulations. Choosing secondary glazing sash windows will bring your traditional property into the 21st century.
Cost-Effective Choice
Affordable Secondary Glazing for Enhanced Comfort
A common reason that people choose secondary glazing in London, Essex and the surrounding areas is that it is very affordable. Secondary window glazing is a cost-effective alternative to double and triple-glazing, which is able to improve a property’s thermal performance, improve safety and security and significantly reduce noise.
With the right type of glass and cavity thickness, secondary window glazing can reduce the noise in your home by up to 80%. Most people have secondary double glazing fitted as a temporary measure until such a time when double glazed units can be installed. However, our secondary glazing in London, Essex and the surrounding areas is completed to the highest standards and will serve you well for extended periods of time too.
Versatile Application
Enhance Any Window with Secondary Glazing
Secondary window glazing isn’t only suitable for single-glazed windows. The method uses a discretely installed pane of glass over the top of your existing single, double or triple-glazed window, giving your home or business an extra layer of protection from the outside world. The addition of a second pane of “low E” glass, which is coated for enhanced energy efficiency, will reduce heat loss by more than 60%. Installing secondary glazing will result in notable savings on your gas or electricity bills and a reduced carbon footprint of your home.
As secondary glazing suppliers, we offer a fantastic choice of products. Our secondary window glazing is of the highest quality and can also be colour matched with over 200 options offered on the RAL colour chart, giving you complete control over the aesthetic of your home or business.
