How Thermawood Can SAVE YOU THOUSANDS Of Dollars?
Ripping out your window frames and installing new double glazed windows is like undergoing unnecessary surgery on your existing windows.
It’s more expensive, riskier and more intensive and doesn’t always achieve ideal results.
Whereas the patented Thermawood process is compared to a non-invasive, in-patient procedure.
These are just some of the Thermawood installation advantages that save you tens of thousands of dollars:
- Less downtime– installing a retrofit double glazing system takes only a few hours. The installation process is seamless compared to a new window installation, but you still get all the benefits and more.
- There’s less risk– because only the single pane of glass is removed and there’s no risk of structural damage to your home.
- It’s more efficient– with Thermawood, window technology today is more advanced, meaning there’s no longer a need to rip out your existing timber windows just to enhance the performance.
WARNING! What Most In The Industry Don’t Want You To Know
No matter what you or your window company does, water is going to get inside your windows. Especially with timber windows, any amount of moisture is too much.
Water won’t just rot timber; it will also cause the double glazed unit itself to fail.
What often happens is, window installers put the double glazed unit into a square rebate.
Then, they seal the window, usually with a commonly used silicone sealant.
At first, the unit is tightly sealed and your timber joinery looks safe from damage.
But unfortunately, this isn’t the case.
Over time, the problems begin to manifest, and water becomes trapped…
And because the double glazed unit is sitting in a square rebate, it is vulnerable to moisture pooling in the rebate.
Water vapour then begins rotting the timber and saturating the seal.
The moisture pulls contaminants out of the silicone sealant which results in water that is concentrated with dirt and contaminants.
This slowly deteriorates the polysulphide seal of the double glazed unit…
And once the seal becomes damaged, moisture and air get into the double glazed unit and you end up with that misty look on the inside of the glass.
How Thermawood Overcomes These Major Industry Issues?
Our entire process is designed around longevity…
With decades of knowledge, research and development as leaders within the industry we overcome these major issues in three ways…
Rebate With A 15-Degree Slope
Patented Drainage System
If moisture gets in, it has to get out! We use a unique drainage system, where every 100 millimetres there is a drainage slot. This enables any moisture to drain out underneath the timber bead and your double glazing so it lasts decades longer.
Unique Dry Glazing System
What makes this case study even more fascinating is…
- The homeowner installed solar at the end of July 2016, took out all gas operated appliances which were the water heater, cooktop and ducted heating and replaced these with electrical equivalents.
- Plus, he started working from home in 2017.
Even with the additional energy consumption from the appliances that were previously gas and the homeowner working from home, he reduced his total energy consumption by 61% with Thermawoods retrofit double glazing.
See What Our Happy Customers Have To Say
Cannot speak more highly of this company.
I was amazed that once done I could not see the difference. But they are different with less noise and blocking out the cold. Jacki was a pleasure to deal with and they guys that installed then where great.
I wanted double glazed windows but still keep the wood frames.
Excellent service, quality work and fabulous staff to do business with. Love my double glazed windows in my old 120 year old Victorian weatherboard house. We were able to keep the original window frames and now have beautiful double glazed windows. We highly recommend Thermawood.
Mark, Paul and the team delivered an excellent project for us.
Great product, careful team and adaptive to our schedule. Thoroughly recommend them.
Excellent standard of finish and installation as well. Very professional measure up and quote process. We are delighted with the job and the increased comfort of our home. Highly recommended.
Pietro’s service is really wonderful he makes sure
He delivers on his promises and goes the extra mile to make sure everything is perfect. The double glazing works a treat and has really reduced noise in our front rooms that face a busy road. It is so much easier to work and sleep in those rooms now and they look exactly like the beautiful original windows because they are the original window frames with clever double glazing. It is also excellent value for money!
Thanks to the new windows
We can sleep much better now as we can barely hear the noisy cars outside anymore! Also, the bedrooms feel warmer in winter, and cooler in summer due to the great insulation properties of the new glass.
Thank you to Jacki and her team. They were very professional and provided a top notch service. Would highly recommend!.
Highly recommend Thermawood’s services
We are very impressed with the quality of double glazing and all the associated benefits we’ve received from them. The double glazing and restoration of our leaking, cracked old leadlight windows has been particularly impressive – we love them. Plus, all our dealings with Jackie and Hawea made the whole experience an actual pleasure (hard to come by when renovating!).
I searched for a commercial solution
To improve the thermal performance of the sash windows in our Victorian double fronted workers cottage for a few years. I came to the conclusion that double glazing was the best option to meet our requirements including retaining the home’s heritage values.
Their local sales rep, Jacki, is friendly, well informed and professional. The installation team, led by Hawea did a great job.
The overall experience with Thermawood has been fantastic from start to finish!
The initial assessment was very informative, and any potential issues were pointed out in advance, and suggestions were made as to how to reduce the cost of the installation. We were run through the installation process and told exactly what to expect. A detailed quote was sent to us with multiple options to chose from, depending on price- and overall requirements.
Thanks so much to Pietro and the guys from Thermawood
They were very tricky to do, but the end results were better than we expected. Pietro was great at explaining all the options and helping us with the choices we made. A few small issues were felt with quickly and without any problems. If anyone has old sash window that they would like to improve the performance of but don’t want to replace, I would highly recommend these guys.
We highly recommend Pietro from Thermawood in Sydney.
Pietro and his team refitted a number of windows with acoustic treatment to reduce road noise whilst maintaining heritage look of the windows. The work was done on time and to a very high standard. Attention to detail was excellent and we are very happy with the end result. Thanks Pietro!
We have been delighted with every step of the process and with the final product..
Installers arrived on time, were a pleasure to have around and cleaned up after themselves. We had around 38 windows replaced so it was a big job carried out with almost no disruption to our daily routines. The finished windows look great and we are enjoying the thermal benefits already.
We have just had several largish window areas retrofitted with double glazing by Thermawood.
We are extremely happy with the result, a great looking result and are feeling the benefits straight away. We needed a doggy door installed in one and the advice and result were fantastic.
Excellent service and product.Has been very effective in noise reduction and damp air flow which is exactly what I wanted.
Passion and patience for the product.
Great outcome for the sound reduction and thermal efficiency in a very hot summer.
Installed 24 panes of double-glazing & 6 flyscreens with winder mechanisms
Mainly for thermal performance. Went for the Argon in all units and EV coating in all but north facing windows, which are being combined with an awning to let sun in in the colder months but out in summer.
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. Conor
Can’t recommend the work of this company highly enough.
Well thought out plan beautifully executed with care, focus and precision. The new windows have changed the way I live in my house for the (much) better.
We dealt with Pietro from Northern Beaches branch. Once we got initial mix up sorted out things went well.
The quote was provided and then when he came to do final measure we discussed possible changes which were agreed to after site visit. The windows on the southern side of the house were fitted in one very long day at the beginning of Sept 2018. We are very pleased with the result and finish. The staff who did the fit out were polite and cleaned up after the work was completed which was lovely.
Pietro & the team went above & beyond to provide a product that met my needs & fitted my old house.
Could not recommend them or the Thermawood products more highly.
Pietro and his team were very reliable, considerate and cleaned up afterwards.
They delivered what they promised in their quote. They were friendly to deal with and accommodating to changes..
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.
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.
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.
Excellent product. Great service.
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!
Great product and service
Great product and service, very happy with Pietro & his team.
A great experience
A great experience from start to finish with excellent follow-up and attention to detail.
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.
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.
An absolute pleasure
An absolute pleasure to deal with, patient explanations, well priced & a great product
My new Thermawood windows in my heritage house are terrific
And have made my house much more comfortable thermically 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.
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.
We recently had double glazing to retro fit some windows in our Edwardian house.
he job was done professionally and the final result exceptional. This outfit is most definitely recommended.
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.
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.
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
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.
Mark from Thermawood was fantastic.
He is hard working, careful with your house and cleans up diligently after the day. We are very happy both with the product and the quality of service provided.
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
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.
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.
I was highly fortunate in coming across Thermawood – Mark Goodwin & Crew.
The applcation, 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 proffesional manner – which was my experience carried right through to finished job.
Mark was fantastic. Clear communications and reliable.
Windows are great ..slotting into the saah 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 veey reasonable (Im 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.
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.
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
Excellent service performed in an extremely professional manner. Happy to recommend to anyone!

- Low E (Low Emissivity) glass improves insulation
- Argon is better than air for insulation
- Argon and Low E can be combined for higher performance
- Low E and Argon gas further reduce condensation
- The better the insulation the more comfortable the environment
- The better the insulation the less condensation will occur
- The lower the shading coefficient (SC) the lower the heat gain
- Tinted glasses are better than clear glass.
- Insulating Glass Units help reduce heat gain
- Low E glass can help reduce heat gain
- The lower the visible light transmission (VLT) the lower the glare
- Grey and bronze tints generally have lower light transmission
- Blue and green tints generally have higher light transmission
- Insulating Glass Units slightly reduce the light transmission
- Reflective glasses can cause internal glare at night
- The higher the UV elimination the lower the level of fading
- The lower the visible light the lower the fading
- The lower the heat gain the lower the fading
- Laminated glass helps reduce fading
Tinted glass helps reduce fading
