Frequently Asked Questions

What is secondary glazing?

Secondary glazing is a fully independent frame fitted on the room side of an existing window to form a double window or ‘double glazing’.

Why use secondary glazing?

While the main benefit is to reduce noise pollution to a minimum, secondary glazing will also help you conserve energy and improve your home’s security.

As it does not affect the character of your building, secondary glazing also satisfies Heritage and Conservation bodies if you live in a listed building.
