What Is the Difference Between Triple Glazing and Double Glazing?

This is a question we get asked a lot – although double glazing offers an energy-efficient solution to your home, triple glazing can offer even more warmth and added security. Take a look and see if triple-glazed windows are the right option for you.

Triple glazing offers you an extra layer of security and efficiency, meaning that your home will be even warmer and more secure.

About Three Counties - Triple Glazing Benefits

Triple glazing is 40% more efficient than 'A-rated' double glazing

Triple glazing is essentially an even more enhanced version of double glazing. By adding an additional glazing panel to your windows, you get an even more efficient level of heat retention and an extra layer of security.

Triple glazing is 40% more efficient that ‘A-rated’ double glazing, meaning you can feel warmer this winter and save even more money on your heating bills. If you live in an area with a lot of outside noise then our triple glazing will also add an extra layer of protection from that sound and will ensure your home is peaceful inside no matter how much noise is going on outside.

That extra pane of glass also helps make your home even more secure as the glass is harder to break, giving you and your family peace of mind. Our multi-point locking systems come as standard to give you extra confidence that your new windows are safe and secure and we also offer a free comprehensive guarantee for every window we fit.

Three Counties - High Acoustic Performance

What styles of window are available with triple glazing?

You will be happy to hear than almost every window we offer is available with double or triple glazing – the choice is up to you.

If you are looking to give your home a modern and contemporary look then our triple glazed aluminium frames will be the right choice – the frames are thinner and more versatile than uPVC and they can be sprayed to virtually any colour. If you are looking for a truly bespoke window then aluminium triple glazing will be the right option for you.

For an affordable and stylish option, our triple glazed uPVC windows will give you a secure and energy efficient option. For a more traditional finish, our timber effect triple glazed windows will be a sympathetic addition to the look of your home.

We recently decided to replace our front door, and could not be happier with the result! Thanks so much to Kate, for her time and understanding. Cannot say enough good things about the installation, and Cameron was tidy and efficient. It's been a pleasure to work with Three Counties recently, doors and windows. Many thanks!

Excellent service!! We had 21 windows and 3 doors installed and very happy with it all. The process from start to finish was stress free and Ron and Lee who installed the windows and doors were great. Would definitely recommend!

Just had my tatty old windows replaced by Three Counties, and it’s been a highly professional job from start to finish. Communication from the administration team was prompt and courteous at all times, and installation ended up being much quicker than advertised projections. Installation was without issue and the lads who did the work were amenable to my requirements and did an excellent job. Very happy with the entire process. Three Counties were recommended to me by friends and I can certainly now recommend them to others.

Bought two new windows and a new front door from Three Counties, was very impressed with the attitude of all staff, who were friendly and informative. Price was good, and installation completed without a hitch - very happy with the final product, and would definitely use again.

We have just had all our windows (18) replaced, french doors (20 and side panels (2) by Three Counties. We could not be more pleased with their workmanship and the finished product. They left the property incredibly clean after each day, and this despite the messy nature of ripping out old windows and frames. We were kept informed at each stage and a minor snagging issue was resolved promptly and efficiently after installation. A first class service. We would not hesitate to recommend Three Counties.

Three Counties have now installed several windows and doors on our house and they're always my go-to company. I used another before I discovered them and they let me down, but I absolutely cannot fault Three Counties. From the moment you contact them they're courteous and professional, and they keep in touch with timescales and installation times. Friendly installers too, who go above and beyond. You'd think all this great service would cost more but they beat other companies on price. Highly recommended and trusted, I'd never go anywhere else now.
