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 glaze windows are the right option for you.

About Three Counties - Triple Glazing Benefits

Triple glazing is 40% more efficient that '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.

If you are considering triple glazing for your new windows then our friendly team will be happy to help you make an informed choice. Call, email or visit our friendly Camberley showroom and we will be happy to show you all the options available to you. We have more than twenty years of experience fitting windows throughout Surrey, Hampshire and Berkshire and our reputation and trusted score with Check a Trade means that you can feel confident when choosing us to help you transform your home’s look, security and energy efficiency.

We used Three Counties to replace our front door and porch. Throughout the process, from design, quote, survey and installation the service and level of communication has been fantastic from all involved. The installation team were great, friendly and courteous, working cleanly and tidying up after themselves. We would have no hesitation using Three Counties again, or recommending their services.

Fantastic service from start to finish. Kept me upto date all the way through the process. Very prompt coming out to measure up and discussing what windows I would like. The install was done professionally by a fab team (James and Josh), cleaned and tidied as they went, friendly team. Would highly recommend

Very happy with Three Counties. That’s the second time we have ordered services from this company and both times it was flawless. Prices are very competitive, customer service very good and workmanship excellent. I trust this company 100% and will be definitely be using them in the future. Paul, gentleman who fitted the door, done an amazing job. There is nothing there that person like myself (with slight touch of OCD) would have an issue with. Highly recommended local company that you can trust.

We used Three Counties to replace 7 windows at our property in February 2022. From the initial quotation, through survey to installation I was extremely impressed with them. The installation was completed by Dan and Cam who I cannot praise highly enough. Their workmanship and attention to detail / finishing was exemplary. They were polite and worked hard / efficiently to complete the job in 1.5 days. They took great care to protect carpets and furnishings whilst working and spent time tidying up, leaving the property very clean. I would not hesitate in strongly recommending this company.

Professional installation by the team including brickwork and windows will definitely be using again for other windows at the property
Excellent service all round from Three Counties. I fully recommend this company, the fitters Ron and Liam were brilliant, thorough, polite, continually clearing everything away, very tidy, helpful, punctual and never wasted time. The windows and doors are great, one very happy customer.

The quote was the price (no hidden extras).The quality of the doors we purchased and the fitting of them was top notch It is nice to find a company that keeps you informed as regards fitting etc at all times We had a problem through no fault of 3 counties and they sorted it efficiently and effectively.We were kept up to date at all times. I have no hesitation in recommending them to anybody thinking of any form of double glazing. This revue would not be complete without a big thankyou to Kate and the fitters.

We are so pleased with our new bi-fold doors supplied and fitted by Three Counties. The job was done professionally and in the time frame provided. Dan and Cam took the upmost care on installation to ensure everything was perfect and they were a pleasure to deal with. Credit to the administration team also who kept us fully informed of the process and schedule. I would highly recommend Three Counties for their workmanship and already have to our friends, who have employed them to do their conservatory
