Five Star Rating

We'd already had 4 quotes when a friend told us to go to Thermaglaze. They not only shaved off $7,000 off our best quote, but custom designed, built and perfectly installed our AMAZING new windows and doors in just 5 weeks!"

“Amazing double glazed windows and doors, such good solid quality, designed and installed by Lee, Anthony and the Thermaglaze team. We live on a very busy road and needed top soundproofing so Lee specially designed our windows to their highest acoustic performance. It all worked so well that we replaced our other windows and even our front entry door with Thermaglaze. The team worked great with our builder and we had lots of options on colour and finishes to choose from. Very happy with this soundproofing we invested in, plus this winter we are already noticing that we need to heat the house a lot less! We are 100% happy customers, many thanks Lee.”

"We renovated 2 of our Units on Parriwi Rd Mosman that was adjacent to the busy Spit Rd. The existing windows could not cope with the noise, Thermaglaze promptly delivered a quote and once agreed, the works were carried out efficiently and professionally. The results are remarkable, peace & quiet. I’m happy to recommend Thermaglaze to anyone.”

Mark Carrigan, Mosman, NSW

"The change from timber windows to the Thermaglaze product was, in the end, a simple choice. The result is our quality of living has been improved by a significant increase in the overall house insulation plus the additional bonus of added soundproofing.”

Murray Baker, Mosman, NSW
