Energy Efficient
Triple Glazing

Triple glazing uses the same technology as double glazing, which works by trapping dense gas between glass panes to limit heat transfer. However, it uses an extra pane of glass and an extra pocket of trapped gas.

This enhances heat retention even more than double glazing and makes sure none of the outside cold enters your home. Enjoy a consistent temperature all year round. We are proud to be at the forefront of the industry, providing the most innovative products and bringing them into your home, such as triple glazing. Whether it is heat generated by the sun or heat that has been created indoors, the extra pane in our windows helps to maintain that heat and maximise energy efficiency. You could even see a reduction in your energy bills!

Suited to Your Home

Every person was polite and professional, helpful and personable. The process was simple and clearly explained each step of the way. It is rare to get such good service, not to mention the quality of the products. I am very pleased with the windows, the fitting, the price and the experience as a whole. I would happily recommend Britannia Windows.
From the salesman to the office staff and fitters, everyone was thoroughly pleasant and helpful so an excellent experience all around. I'm very pleased with the windows too, they look great. Would recommend without hesitation.

Great job of our new front door. They couldn’t have been more helpful and even fitted earlier originally planned. Also gave great aftercare advice and at a very reasonable price! Would 100% recommend.
