Being an engineer I have always known of the benefits of double-glazing. However, due to the costs involved with replacing the double hung sash windows and frames in my Victorian house I never did anything to retro fit more efficient windows. Then, one day with the help of “Mr Google”, I found Thermawood’s website claiming to be able to fit double-glazed panels to my existing sash windows. From my first contact with Thermawood I have found the process to be efficient and very customer friendly. I measured my existing windows and sent these to Thermawood using their spreadsheet. Jacki’s team then quickly developed a budget price. Upon my acceptance of the budget price Thermawood travelled the 200 km to my property, measured the windows themselves and then gave me a firm quote (slightly less than the budget). After I had accepted the quote and paid a 50% deposit the glass was ordered and an installation date nominated. The glass arrived on the day specified. The installation team arrived as nominated and quickly installed my new panels. The installers were courteous and friendly. They left no mess and thoroughly cleaned the worksite. Have the new panels worked? It’s too early to make a judgment, however visitors have commented the house seems warmer. (I have not raised the heating thermostat.) After a few more months I should be able to compare this years gas bills with the last few years. I would highly recommend the Thermawood process and their team.
We are so so happy with our lounge retrofitted wooden double glazed windows – the guys were absolutely awesome – so lovely and professional. The first window was completed by Michael and James who were amazing and a few days later Michael and James completed the second lounge window with another 2 guys who were equally competent and friendly. This window had quite a bit of rot and they made new sashes etc which matched identically with the original windows – beautiful craftsmanship. Can’t speak highly enough of these guys and Thermawood – would highly recommend them. No condensation now and the lounge feels so much warmer. Hopefully, we will get them back next year to complete another window or two! Thanks to the whole team from quote to installation – very professional!
This is a really good product supported by great service by Jacki who was always prompt and helpful and by the men who installed the glazing. They were polite, clean and professional. As for the outcome I am pleased with double glazing and particularly the seamless integration into a 100 year old Vic terrace sash window. Highly recommended.
Awesome peeps – from whoa to go. Thank you so much – we are snug as bugs and it feels good and looks amazing.
We recently had Thermawood double glazing and door seals installed in the living room of our house in Adelaide. We are very happy with the result as it has made a noticeable difference to the effectiveness of the heating in our main living area. Graeme and Steve did an excellent job installing the system with minimal disruption to us. We were also appreciative of the follow through from Kym. I can recommend the Thermawood system as an excellent retrofitted double glazing option.
The guys from Thermawood were a pleasure to deal with. Their advice on choice of glass and the necessary work was clear, they delivered on time and at a great price. I was particularly impressed by their efficiency when they came to fit our windows. Everything was done with great care and they tidied up perfectly at the end of the day. The new windows have made a real difference to the thermal comfort and noise level in our lounge room. Thanks a million Thermawood! All the best.
Can I say that the gents have done a brilliant job on the windows. Very impressive window seals etc and it puts pressure on me to paint them when warm weather allows in Spring I guess. Not the best of days to tell if the windows have made a temp difference as the ABC news/weather said it was the coldest day in Melbourne today since last August and as the windows were being worked on, naturally the cold air sapped the stored heat out of brick work. But I can say so far that the sound mitigation is incredible. It is difficult to hear cars in ***** Street and those passing our home in ***** Street appear much quieter. So far we are very impressed with no condensation last night on the glass! Will keep you posted on how they perform. Again a very professional job with excellent materials and fittings. All the best.

Hi Jacki, Thank you for your advice and taking us through each process. You’re customer service is outstanding! In appreciation.
I would highly recommend Thermawood. They were reliable and communicated everything clearly. The new windows are excellent!
Well organised job. Second floor so needed extra effort for access. Noise from main road reduced. Flat now snug for winter. Would recommend.
We engaged with Thermawood for the front windows of our Victorian Terrace. Primarily looking to improving the security with the laminated option, however our leadlights and window frames were not in the best condition, and Thermawood was able to rectify this also. When our leadlights returned, the condition and look of them exceeded my expectations. The look of our leadlights now is incredible, the double glazed unit provides an effect which enables light to reflect off the leadlights giving them another incredibly appealing aspect that was previously not possible. Along with the windows being sealed and rejuvenated this has been the greatest capital investment to our home, that I continue to admire and talk about on regular basis. I highly recommend the Thermawood solution.

Jacki & Hawea provided amazing customer service, and it was pleasure dealing with them. While getting our windows involved a few hiccups, they were mostly to do with our windows being old & bad, not to do with Thermawood. And we love our much quieter house.
Extremely pleased with the Thermawood team, led by Pietro. Very professional, excellent workmanship, quality product and very thorough. This was a tricky job and the final result is fantastic!
I was highly fortunate in coming across Thermawood – Mark Goodwin & Crew. The application, was fitting double glazing to 2 × arch double hung windows’ in a heritage home. Mark at the start, consulted on the details, providing a quote for the complete fitting in a highly professional manner – which was my experience carried right through to finished job. During the work – the care taken for keeping the area tidy, and concern for preventing damage inside & outside the premises was meticulous, and impressive. The objective of the double-glazing retrofit was to reduce traffic noise from a busy intersection, and improve insulation. Living the result, I can strongly say; of being very delighted with the performance – it is very good, giving a highly notable response, to both noise & internal house insulation qualities. On a personal level, “The Crew”, was a pleasure to experience. The care to the high quality of workmanship clearly shows, and it is my intention here, to convey my huge enthusiasm for this whole project, headed by Mark. If it was possible, I would like to go 5 star+ +.
A pleasure to deal with Pietro and Graeme from Thermawood. A professional, problem solving, friendly team. I love my new windows and would recommend Thermawood to anyone wanting to upgrade their windows.
We’re really pleased with our windows, particularly the replaced lead lighting. Jacki and Hawea were great to deal with and I would recommend Thermawood if you’re looking to improve your home’s efficiency.
We are extremely happy with the product and work provided by Thermawood. We first saw this product at a home show in Melbourne and after further investigation, felt this was the product for us providing double glazing and security as well as keeping the original look of our house.
The product is high quality and performs as stated. Increased insulation and decreased noise was noticed immediately. Mark was the person who quoted, worked and communicated with us. Mark also installed the Thermawood product. Mark was easy to talk to and always got back to us when we had questions no matter how simple they sounded.
When installation occurred Mark was careful and ensured the job was completed easily and seamlessly. The completed job looks great. The clean up was part of the job and no mess left which was an added bonus. Mark is very careful and professional with his work and is easy to have around the house.
Security supplied by these window retrofits is greatly appreciated. A very professional company, people and product. I have no hesitations recommending Thermawood to any person contemplating double glazing existing timber windows. Apart from increasing insulation the laminated glass increases security as well as decreasing noise. Once again excellent company, product and particularly people.
It was a pleasure working with Jacki and the Thermawood team. Fantastic products and double glazing solutions. Our heritage windows have a new lease on life! Thank you.
We recently had double glazing to retrofit some windows in our Edwardian house. The job was done professionally and the final result exceptional. This outfit is most definitely recommended.
Just had Jacki and Hawea install 4 double glazed IGU units in window right next to our massive and noisy outside heat pump compressor unit. What a difference 6.38mm Lam + 10mm gap (argon filled) + 4mm toughened clear float + high quality acoustic seals make compared to 3mm float! If you want to hire the most dedicated team who won’t leave the job till you are 100% satisfied with their efforts, Thermawood is the company to hire!
Thermawood retrofitted double glazing to two wooden-framed windows at our home. We are delighted with the outcome. The windows look absolutely great, the two rooms are noticeably quieter and much much cosier than before. The two windows were challenging (one is a box window, both turned out to be very finicky) and Jacki and team went to great efforts to make sure that we ended up with a really great outcome. Recommend without hesitation.
Jacki and Hawea have spent 2 weeks at our home converting all our windows to double glazing – a huge job 52 panes of glass!
As an interior designer, I spend a lot of time working with different trades. Jacki and Hawea were exceptional. They arrived every day bright and early with a smile on their face and an infectious energy and attitude. Each day they had a goal of a specific number of windows that needed to be fitted. They didn’t leave till that goal was achieved.
Every renovation has its challenges – our project was no exception. You can tell Jacki and Hawea are ‘seasoned’ professionals. The hiccups didn’t faze them. They resolved them with no drama and in a timely manner. My husband and I made a few variations throughout the process, which involved ordering more glass and replacing windows that had already been installed. They were accommodating and willing to make whatever changes we wanted in order for us to be 100% happy.
Their craftsmanship and attention to detail was impeccable. As an interior designer, the finer details are extremely important to me and create the lasting impression. Jacki and Hawea understood that and talked through the finishing details whenever it was required.
They were an absolute pleasure to have in our home. They cleaned up thoroughly every day.
The windows look amazing, they have added a contemporary feel to our home – we couldn’t be more happy.
I would recommend them in a heartbeat – they are the hardest working, kindest couple I have come across in a very long time!
I wish them all the success in their business, they absolutely deserve it.

“Having had the house fully Double Glazed at Easter the benefits are fantastic. The house is drier, warmer and a pleasure to get up to in the early mornings at 3am. The guys did a great job William and John and even impressed the neighbours by the way they worked and cleaned up. Thanks Guys
Mary & Peter, Turangi
Pietro and his team have a great product and fantastic customer service. They are responsive and tidy and do all they can to meet your needs. We wanted to make our old 1970s home as warm and efficient as we could and retrofit double glazing with Thermawood has made all the difference.
We are so happy with our new windows, Stephen is now converted he woke me up last night to tell me that he hadn’t heard the trains go by…I am very amazed
Natalia & Stephen
Mark and his assistant were very helpful and pleasant and the job was done professionally and very quickly. I will recommend them to anyone who has similar needs.
We live on a very busy street in the eastern suburbs of Sydney with buses, trucks and many cars. Our house is an old terrace with original wooden windows and door. We were after noise and thermal properties improvements. We had acoustics glass external with argon in between the 2nd pane. Glass in the door and in the panel above the door were treated the same. Install took a full day into existing windows and doors.
Noise greatly reduced, cozy and warm in winter now and can still fully open windows when we need to.
Well done job, done in a timely manner.
Well done job, done in a timely manner.
Excellent service performed in an extremely professional manner. Happy to recommend to anyone!
Very happy about our new double glazed windows, could feel the difference from Day 1: less cold and less noisy! Had an impact on our energy bills as well?.
I have been looking for affordable and high quality double glazing system for over 5 years. Each time I asked for quotations I was disappointed with the technology let alone the huge cost. It never made sense to me to replace perfectly fine existing window frames as this is very labour intensive and costly. When I learned about technology used by Thermawood I thought that this made perfect sense to me. They replace glass component of the existing window rather that window frame + window itself. This technology have been successfully used in New Zealand for 40+ years. It allows home owners to provide better insulation from heat/cold/noise as well as reduces chance of wood rotting, draught etc. and it is also VERY cost effective. Mark and his team are very professional, arrive on time, get things done and do not leave any mess behind them. They are friendly to owners as well as neighbours, work hard to get job done in the shortest possible time. I can recommend Mark and Thermawood to anyone who is looking for system that reduces heating/cooling bills at a very affordable price.
Mark was fantastic. Clear communications and reliable. Windows are great ..slotting into the sash windows at my Victorian terrace and really lowering outside noise and keeping the house warmer. Mark also did an excellent repair on a window frame that had rotted and at a price that was very reasonable (I’m sure I could not have got someone to even turn up for what Mark charged). The house was also left spotless. A great experience and product.
Very nice people to deal with. Knowledgeable about their product, hard working and efficient, and come when they say they will. I would recommend the Thermawood product and Jacki Cook of Thermawood Boroondara to anyone considering retrofitting double gazing to existing timber windows.
My new Thermawood windows in my heritage house are terrific and have made my house much more comfortable thermally and acoustically. The double glazed units fit discretely in the window frames without impacting the heritage look. The old window mechanisms have been updated and all work well now. The Thermawood staff were delightful, prompt and the highly experienced technicians worked hard and very conscientiously with a great old fashioned, caring customer service attitude. I was highly impressed and recommend them confidently.
I am just so impressed with our new retrofitted double glazing from Thermawood. The whole process, from quoting to completion, was seamless and stress free. What a great team Hawea and Jacki are. Their workmanship was excellent, and they had a great desire to make sure that every detail of the installation was perfect. I will be definitely recommending Thermawood to our friends and family. Thanks a lot guys.
Mark and his team were very efficient and installed a great product. We were very impressed with the way that they worked, cleaning up at the end of each day and ensuring a tidy work site.
The Thermawood system is the only one that I found which cleanly integrates proper IGU double-glazing units into existing wooden windows. Ours are a combination of fixed and awning sash windows, and also one sliding window, one sliding door and one regular glass door were done. All of them look great!
Thermawood installed their double glazed system with low-e tinted glass and argon gas fill in our east-facing rear bay windows. The reduction in heat and glare from the morning sun has been fantastic and the finished product looks amazing. I cannot complement Jacki and her team enough on their communication (both before and after installation), attention to detail, and care with installation and final clean-up. The pricing was very competitive with alternatives and the windows slotted perfectly into the existing wooden frames, maintaining the original look of the house. We were so happy with the final product that we ordered new windows for the west-facing front of the house too. Andrew & Sue.
An amazingly effective product professionally installed by Jacki and Hawea. Window is next to a new & massive 23Kw heat pump compressor. Noise levels have been cut down considerably with 6.38 Lam, 10mm argon and 4 mm float in place of 3mm float. Jacki and Hawea also installed very effective acoustic seals around the awning window. They stayed and fine tuned acoustic seals until I was 100% satisfied with the job. Jacki took my vacuum cleaner and ensured the room was as clean as when she first arrived. I highly recommend Thermawood double glazed retrofit glass company.
Our 1960s timber windows had double-glazing retrofitted by Thermawood. Very happy with the appearance and performance of the product. While the appearance hasn’t changed noticeably (the look of the timber frames and the low-e film on the glass), the thermal performance has improved significantly.
Thermawood were also able to change our winders and weather-seals for an additional fee. Jacki was fantastic with communicating to us during the entire process (from pre-quotation to post-install). Very happy, will definitely get some more windows done.
