What are the benefits of double glazed patio doors?

As well as all the aesthetic benefits you get when adding beautiful sliding patio doors to your living space, you will also get many practical benefits that improve the security, energy efficiency and value of your home.

All of our double glazed patio doors offer a fantastic energy rating – meaning you won’t have heat escaping from your home in the winter months and in turn this can lower your energy bills if you have existing older patio doors that offer a lower energy efficiency.

Our doors also offer a multi point locking system to enhance the security of your doors. Our advanced double glazing technology uses Pilkington Glass – a well respected brand that you can trust. Our secure seals, locks and double glazing also mean you can enjoy high acoustic performance that reduces unwanted noise from outside. Our double glazed patio doors also feature the UK’s best performing window system and the world’s best rated weatherseal gasket to keep damp, rain and drafts out of your home. All of our patio doors are available in a wide range of gorgeous colours and you have the option of upgrading a maximum performance triple glazing if you wish.

Was looking for a new front door, to replace our tragically 80's monstrosity. The Three Counties website was great as i could see and design the door i wanted and then get a quote for it. The sales team was really quick to respond, and not at all pushy. A survey was easily arranged, to confirm sizes etc and the installer turned up precisely on time, was super friendly, efficient, neat and very tidy. Whole process took about 4 weeks, beginning to end, and I now have the door of my dreams! The only downside is my neighbors keep pestering me for details of who did the job. No hesitation in recommending Three Counties.

I'm very happy with my new conservatory - Mark and David did a brilliant job of the build and resolved any issues I had to make sure everything was finished to a really high standard.

This is the second time I have used Three Counties , a few years later and in a different house this time. It’s great to see the quality of the windows and workmanship have remained 5*. A stress free installation from start to finish, all windows installed have transformed how our 70s style house looks and now no worries of mould as a result of the old timber framed windows. The Installers who completed our job were amazing, and I mean amazing! Hard working, extremely skilful at their trade, polite and very tidy. Each day when they left they hovered up and left the place in the best condition they could. The whole process from the initial quote , measurements and dealing with the office team before and after the installation has been a true pleasure , if only all businesses were as efficient as this. Highly recommended for anyone considering new windows or any other products they provide and I won’t hesitate to use them again. Thank you Three counties!

I shopped around and three counties came in at the most reasonably priced, and I used the buy now pay later option. Really happy with my new door and window, which were both fitted in one afternoon. The customer service was very good throughout and everything went smoothly.

I had some windows fitted a few years ago and have recently had a problem with one of the locking mechanism failing. I called 3 Counties, who had a base call out charge, where a lovely lady took my details, refered to my file and we agreed a date when the fitter would come out and inspect the issue. Paul arrived bang on time and was very helpful. He checked the window, confirmsd the issue and promptly fixed it there and then with a replacement part he had on board his van. He was polite and knowledgable. Very efficient. Thank you 3 Counties.
