Secondary Window Glazing is a cost-effective retrofit solution for improving energy efficiency in existing windows. It can minimise condensation, reduce noise pollution and help to protect your property from burglars too.
The simple addition of a second slim pane helps to create an air gap that significantly reduces the amount of warm air that escapes from your window, and allows colder air in during the winter. This in turn can lead to reduced heating costs, lower carbon emissions and a more comfortable home.
Transforming Your Home: Exploring the Best Secondary Glazing Choices
A good quality system will have a U-value of 0.27, which is considerably lower than a baseline single-pane window, according to the experts at Clearview Secondary Glazing. They also say it can result in a 5-15% reduction in energy usage for heating and cooling, and will save you more than £300 per year in comparison to a new replacement window.
There are several different types of secondary glazing, each providing slightly different benefits. The cheapest option involves sticking an extra sheet of thin transparent plastic film to your existing window, and it’s not hard to achieve this yourself using strips of standard double-sided tape around the frame. Just make sure to leave some overlap and use extreme tape (25mm thick) as it’s better for the longevity of your glazing.
Another option is to have a glazed unit manufactured to your specification from either aluminium or wooden framed, which can be face fixed or reveal fixed. It can then be fitted to the inside of your existing windows, and it comes in a range of colours so that you can match it to the colour of your frames.
