Secondary glazing in the UK is particularly popular because of the stringent UK laws governing listed and heritage buildings and properties in conservation areas. Working along very similar principles of double glazing it involves fitting a secondary pane of glass on the inside of existing window frames.
As well as not altering the original aesthetic appearance of a property’s exterior, secondary glazing brings with it many of the benefits of double glazing such as noise reduction, energy efficiency and increased security.
Available with uPVC, aluminium and timber frames the secondary pane makes for a great insulator and is commonly used in historic public buildings such as hotels, churches, schools and official government offices.
Handy Tip: For the most effective acoustic insulation, ensure that the gap between external window and internal frame is a minimum of 100mm.
Three things you might not know about secondary glazing:
- It can help reduce condensation
- It is often a fraction of the price of double glazing
- It can come in kit form and so makes an easier DIY project than full blown double glazing installation
