Energy Efficient Windows

How to make sure you're buying an energy-efficient window

Windows may all look the same, but they certainly don’t all perform the same. It is now easy to compare and assess the energy efficiency of a window by looking at independently verified scores.

At Ripton Windows, we measure our windows’ effectiveness using a WER (Window Energy Rating) developed by the British Fenestration Rating Council (BFRC). The BFRC is the UK’s nationally recognised scheme for measuring window energy efficiency.

The BFRC rating system grades the performance of a window based on letters from ‘G’ for the worst performing window up to ‘A++’ as the best performing window.

The WER Rating is calculated using the following three factors:

Thermal Transmittance

The U-value measures how easily heat can pass through a material; the lower the U-value, the more efficient the material.

Solar Factor

The G-value measures how much heat can pass through a window from the sun; the lower the G-value, the more protection the glass has against infrared radiation.

Air Leakage

The L-factor measures how airtight the window is; the lower the L-factor, the more draught-proof your windows will be.

Our Windows

Thermal transmittance, or the U-value, is a measure of the rate of heat loss and is measured as watts per square metre, per degree Kelvin (W/m²K). The lower the number, the more efficient the glazing.

In order to meet the governments thermal performance targets and current Building Regulations, all replacement PVC-u windows need to achieve a U-value not exceeding 1.6 W/m²k.

Origin Windows

Origin window glazing offers a U-value of 1.2m²K on the OW-70 Slimline Window and 0.8 m²K on the OW-80 Premium Window.

Ultimate Windows

Ultimate Windows achieve an A+ Energy Rating with an Energy Index of 10 and a U-value of 1.4 W/m²K.

Lumi Windows

Lumi’s edge to edge design with no vertical or horizontal frame allows more light in. Argon-filled, low E-glass and super-tight double gasket seals let less heat out with double and triple glazing options with a WER rating of ‘A’ with a U value between 0.8 and 1.2.

Roseview Windows

All Roseview windows are ‘A’ rated as standard, with a U-value of 1.5 W/m²K. With different glazing this can be further enhanced where required.

Reduce heat loss with quality triple and double glazed windows in a range of styles to suit your home.

Secure, energy-efficient composite doors, bi-folding doors, patio and French doors. PVCu and aluminium.

Quality conservatories with warm-roofs for an all-year-round room, reduced heat loss and energy savings.

We are extremely pleased with the work done by the Ripton team when replacing our front door. The staff were professional, super efficient, and communicated clearly throughout the entire installation so we always knew what was going on. They handled everything with great care and left the area spotless when they finished. A top-quality job from start to finish. Thank you Dean.

It is easy to sell windows but after care is harder to provide and the Ripton team have been brilliant. I had an issue with a failing lock on a door fitted 4 months ago. I advised Ripton, within hours a fitter was on site, issue solved (user error as it turns out) and whilst he was here he checked all the other work. Excellent service.

Our house windows were fitted by Riptons approximately 14 years ago and they are still like new. They recently replaced our wooden garage door and window, again matching to our existing windows. Last week our front door was replaced with a new ‘door and a half’ meaning the side panel next to the door can also be opened to give wider access which we love. We could not fault the fitter who did an excellent job. All the staff we dealt with were professional and very helpful. We would highly recommend Ripton Windows.

We are very happy with our new door. From the initial home visit to the showroom experience, the customer service was excellent throughout. The fitting team were quick, professional and did a fantastic job, leaving everything clean and tidy before they left. A great company with excellent service from start to finish. We would highly recommend this local family-run business.

We are very pleased with the warm roof replacement on our conservatory and with the way that the work has been done from start to finish. Andy, the fitter, has been brilliant and it was very impressive to see the roof being built, layer by layer. We have no hesitation in recommending Ripton Windows - Matthew, Richard, Andy and the team, have been professional, polite and helpful throughout the process.

The people at Ripton Windows made an excellent job of replacing our four bedroom windows. Everything from the initial contact through to quotation and eventual fitment were all completed on time and with the minimum of fuss. Their communication was excellent and all the staff that we dealt with kept us informed of key dates in the process so we knew what to expect. A great team effort and a special mention to fitter Dean who was so meticulous in the way he installed the windows, taking real care and showing superb attention to detail. Pricing was the best we could find. No hesitation in recommending Ripton Windows, give them a call and I’m sure you will be delighted too.

Have been using Ripton since the 90’s with no issues at all. Current windows 24 years old and still going strong. Had a new back door fitted yesterday and as usual the service was excellent from start to finish. The fitter Dean was very professional and did an excellent job and I would not hesitate to recommend their services 👍

Today we had the pleasure of using Ripton Windows again, and once more they have exceeded our expectations. Two weeks ago, Lee, the Installation/Service Manager, came out to assess a number of our windows that had become blown or were leaking at my request (Not originally Ripton's installation may I add) He carried out a thorough inspection and provided a clear, honest quote with no pressure or sales tactics — just straightforward advice and complete transparency (no pun intended!). Having previously used Ripton’s for an insurance-related conservatory window repair, we already had confidence in their work, but this experience has truly reinforced that trust. Today, Lee completed the installation of nine new window units (retaining the existing frames), and the whole process from start to finish has been seamless. His workmanship is excellent, his attention to detail is second to none, and he left everything spotless. It’s clear why he’s been such a valued part of the company for 25 years — he is an absolute asset to Ripton’s. Plus he's a really nice guy! I don’t typically write reviews, but I genuinely felt compelled to on this occasion. The service we received was professional, efficient, and refreshingly honest — and, to our surprise, more competitively priced than we were expecting. A huge thank you to Lee especially and Ripton Windows for being a genuine customer lead business. My wife and I truly appreciate the quality of service and wouldn’t hesitate to recommend you.

Contracted Ripton to replace our very tired glass conservatory roof (a conservatory that it turned out Ripton fitted some 15+ years back for a previous owner) with a tiled Prefix warm roof one and we honestly couldn't be happier. While we need to wait a while before we can decorate and fully finish the project, the roof is really good. Our conservatory is now much quicker to heat up and it retains heat virtually like a "normal" room in the house now too, making it a room we are going to be able to use all year round (once the AC is installed too). Excellent service from start to finish, and Andy, who fitted the roof, was an absolute trooper, doing it mostly single handedly while being very professional and an all round excellent guy. We would happily have Ripton work on our property again in the future.

This was our first time using Ripton Windows and so glad we chose them! We had a new glass roof replacement for our conservatory, it’s now a well used room. I can’t recommend them enough, from the initial visit and quote to the final finishing up. Service and workmanship were fantastic! Thank you to Matthew, Richard, Paul, Andy and Kirstie!

I went to two local Basingstoke companies, when we decided to change our double glazed windows, from deteriorating wood to uPvc. One, a company which advertises on the radio, and is a much larger company than Ripton, but its sales engineer, surprisingly, was very unprofessional at our meeting (I didn't trust the guy!), and the written quotation he forwarded was also unprofessional and lacking essential detail, which did not impress me. When I queried the price details, he said it was the Yorkshire in me. I did not appreciate this comment, inferring that I am "tight" with money, when I was merely querying what seemed to be an unreasonably high price, and especially as I am from Lancashire!? However, when Matthew Ripton, MD of Ripton Windows visited, the contrast with the much larger supplier, could not have been more marked. He was very professional, friendly and personable and his subsequent quotation was comprehensive, and detailed full technical details of every window separately. Also, Ripton's price was very competitive and reasonable, and, most importantly, Matthew is clearly an honest guy with integrity. I trusted him instantly, which, in my opinion, is key when doing business. The installation could not have gone more smoothly, and without any major problems. It's a brilliant job, and I am really pleased with the work and attention to detail. I came into contact with several people in the organisation, and all are friendly, very helpful, and consistantly professional. A really good team, who work really well together, always keeping the customer informed. All are very nice people, who you can instantly trust. I recommend Ripton Windows, a very stable family company, without hesitation, to anyone considering replacing their windows.

This was the first time we had used Ripton and we will certainly use them again. We contacted Ripton for a Warm Roof quote for our conservatory, having had a quote from the company we had always used, Ripton’s quote was over £3000 cheaper for (we consider) a superior product. We were kept informed about the job by Matthew Ripton, Richard and Kirsty every step of the way from quote to completion and everything went to plan. We can highly recommend the main installer Andy, and Paul the plasterer, both guys were friendly, highly efficient and cleared up every evening. All they needed in return were the odd cups of coffee and tea! Amazing family company which we cannot praise highly enough. Thanks to all of you. We love our ‘new’ room

I have used Ripton Windows 4 times now, and just would not go anywhere else for windows, doors or roofline products, and highly recommend them to anyone who needed these. The price given by Matthew is what you pay, no haggling or pressure to buy. Kirsty in accounts is very efficient and a pleasure to deal with. The fitters are always a pleasant, cheerful bunch. If you are very fortunate and have Lee install your door, you will not be disappointed, his attention to detail is second to none. He is full of helpful advice and tips to keep the windows and doors in good condition, and is passionate about the products. I am delighted with the quality of my recent windows and doors, and look forward to seeing how the winter fuel bills will be affected.

Just had the lads from Ripton replace all our windows in the house and 2 new french doors. Brilliant job,clean and tidy and on completion Dean went round the house with us to make sure we were happy with the work done. We've used Ripton's before and thoroughly recommend them to anyone. Thank you all at Ripton's. Stuart.

This was my second Ripton experience in a month having previously had replacement Sofits and Fascia boards fitted. The installation of Patio Doors proved to be another positive experience. The doors with Rosewood exterior looked even better than I remembered from the showroom and the fitting, by Dean, was an excellent example of experience and skill combining to create a wonderful 'end result'. Dean was polite and courteous throughout the installation and I was extremely impressed by his workmanship.

Excellent service from Ripton windows for a new front door. From initial enquiry to installation everything was of a very high standard- special mention to the installers on the day with great attention to detail that really makes our front door stand out

We have just had a new Gerda front door installed by Ripton Windows. We are delighted with door. It really is a good quality product and I would certainly recommend it to anyone. Also, it was a pleasure having Lee and Richard doing the installation. They were professional and courteous, which makes a welcome change these days. Many thanks also to Matthew and Kirsty for the excellent customer service. I would definitely use Ripton Windows for any future home improvement projects.

Having had Riptons install double glazed windows at my old house when I came to my next home I was only too pleased to entrust them to fit a new patio door as well as do all of the guttering and fascias. The service from the whole team was once again highly professional and helpful. I am very pleased with the work completed and would happily recommend them. Thank you!

We have had the most fantastic service from start to finish from Ripton Windows. Mathew came to see us, completed and sent our quote really quickly, which was an excellent price and we received great advice. An excellent survey guy that was friendly and very thorough. Delivery and instillation was earlier than expected and was a very pleasant surprise . The installers Dean and Dean were swift, cheerful, considerate and very thorough. They were hard working throughout but always polite, helpful and understanding when I made odd enquiries. The attention to detail was superb. Our windows look fabulous. All the office staff we interacted with, Kirsty another lady and Lee (who helped with some little issue) were all so helpful and supportive. We would like to highly recommend this company. We have had almost all of our home re glazed and our conservatory from Ripton and all have been excellent .

We really liked their sales honesty. Matt recommended what was best for us and not the most expensive. The sale was all about making sure the product was fit for our purpose. The fitting (Dean) was very efficient and had little impact on our afternoon as the work was being done. The place was left very tidy. We were also told what TO do and what NOT TO do, with full guidance. Aftersales seems very responsive so far. It has made a huge improvement to the look AND the heat efficiency of our home.
