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. Pietro & his tradesman were a pleasure to deal with & did a great job – it’s old school labour-intensive craftsmanship leaving you with well sealed, smooth operating windows & doors. We’ve also installed a new R/C air-con & it’s able to run on a pretty light cycle with the improved thermal performance of the room. Sound insulation has also been noticeably improved.

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. It can get pretty cold in the Dandenongs but last night we barely used the heater at all and haven’t needed to light the fire for several days. Thank you Jacki and your crew. We will be back for more next year.

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.

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!


An absolute pleasure to deal with, patient explanations, well priced & a great product


Great product and service, very happy with Pietro & his team.

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. We could notice a marked change in temperature within the rooms almost immediately and the noise has reduced a fair bit. I think we should have possibly gone for next level up just for additional noise reducing benefits, as it was we went for double glaze with laminate. We look forward to seeing how they perform when summer arrives and are seriously considering getting all the windows on the northern side of the house done too. We would HIGHLY recommend them to anyone who is considering retrofitting timber windows with double glazed.


Rosie and Pietro Cotino provided a wonderful service to my elderly, frail mother with Thermawood Double Glazing. At every step in the process they were reliable and sensitive to her needs. For example, they were responsive in ensuring the times for measuring up the windows and installation were suitable to her daily schedule. Knowing that the double glazing was important for her sleep pattern, they made an extra effort to schedule the fabrication process as quickly as possible, so that installation could be expedited. The product itself is very good with a number of tailored options for both sound and heat and was within our budget expectations. Our major concern was blocking out noise. The new double glazing has substantially reduced traffic noise in my mother’s room. The windows also looks great – in fact, I initially could not tell what was the old versus the new window frame, as the double glazing frames were installed seamlessly. All in all, a very positive and productive experience. Thank you to the Thermawood team.


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.
