Secondary Glazing

Keeping the warmth up, the bills down and the noise out

If replacing the windows on your property is difficult or restricted, or you simply love the windows you currently have but are looking for improved energy efficiency, secondary glazing is the answer.


It’s a brilliant way to reduce noise, keep out draughts and improve the energy efficiency of your building. It gives you the ability to preserve the external character of a property, without compromising on comfort.

What is Secondary Double Glazing?

Secondary glazing effectively means adding another window inside your existing windows. It sits within its own frame and is fixed to the existing window. It is a non-permanent, removable addition, and is perfect for everything from listed buildings to modern homes where you cannot remove existing windows.

It is an affordable alternative to fitting new double-glazing windows throughout an entire property and can be used singularly for troublesome spots on your home, such as if you live on a main road, it can work as a barrier for noise.

With a wide range of shapes and sizes available to suit any style or age of building or space, and a choice of hinged units, lift-out secondary units and horizontal sliders, we can supply secondary glazing that suits the needs of your home.

B & E fitted a huge aluminium conservatory for me in 2014 at 50% of the cost quoted by a national supplier. It is stunning and we live in it all year round. I can't fault the B & E team, installation and after-care are fantastic.
