Double glaze your timber windows​

For world-class results, we are excited to be the first in Australia to offer Glavenir glazing technology by Panasonic.

Vacuum-Insulated Double-Glazing is proven to perform better than modern triple-glazed units, achieving huge improvements in comfort and energy efficiency.

For excellent results on a mid-range budget, we can also offer low-emissivity single-glazing by Viridian.

All our glass will fit within timber windows without compromising the looks, operation or integrity of the frames. Best of all, your windows will open and close smoothly, with a light touch.

Keeping the noise & weather out

Our draught seals were developed through years of upgrades to timber windows in the cold climates of England, Scotland and Ireland.

They stop up to 86% of airflow and up to 10 dB of noise.

Sick of your rattly, draughty timber windows?

It might be cheaper to rip out your timber windows and replace them with new plastic or aluminium double-glazing units.  However, you will instantly lose the character of your property and it will never look the same.  

Replacing the whole window frame has also been known to cause major disturbances to the structure around your windows, flowing on to create property damage that only appears after the contractor has gone.

On the other hand, keeping original wooden windows maintains and arguably increases the value of your property.

Your timber windows are made of old-growth timber, that has stood the test of time in most cases. 

And with a little TLC and some new upgrades, they can outperform a new window & the frame could to last another 100 years.

Don't rip out your timber windows!

I have recently upgraded my previously rejuvenated sash windows upgraded to the glavenir glass from Panasonic by the Sealasash team. The result is nothing short of amazing. The installation team led by Scott were extremely professional and it all went seamlessly. The thermal and acoustic results are everything and more than what I was hoping for. I can thoroughly recommend this product and the entire Sealasash team.

Exceptional service from start to finish. Communication with Sealasash was informative, responsive and friendly. They provided a quality solution (ComfortHush) to the noise issues I had with old windows and they also sorted out seal problems I had with some external doors. When working on site they kept to their calendared schedule and left my house clean and tidy at the end of each day. My house is a much quieter - and warmer - place to live now. I confidently recommend their services.

We recently had our windows refurbished and fitted with Glavenir Vacuum Insulated Glass. We were very impressed with the efficient way in which the Sealasash team implemented the installation process. The vacuum glass has made an absolutely incredible difference to our home, improving the performance both thermally and acoustically beyond our expectations!

We highly recommend the Sealasash team. Their professionalism, and excellent communication ensured that our substantial project was completed with excellent outcomes. Their highly skilled team installed vacuum-insulated double glazing in 14 large windows in our conservatory. The team was friendly and tackled our project with enthusiasm and a great work ethic. We are thrilled with the result.

We can absolutely recommend Sealasash. From start to finish we were completely satisfied. Jack, Brady and their team kept us completely informed, the quality of the work was first rate, everything from turning up on time, to cleaning up and giving an accurate cost estimate was first class. We have more to do and will certainly engage them again.

Thanks to the team for fixing our broken, stuck casement windows. The house is quieter and warmer without the expense of double glazing or replacing our beautiful 100 year old windows. As an added bonus the final price came in well under the quote. Looking forward to getting our sash windows done soon.

A big shout out to the wonderful mob at Sealasash who have transformed the quality of life in the old cottage part of my home. Money well spent which should have been done years ago.

This was our second experience with Sealasash and we were just as impressed with the professionalism of the team as we were the first time. If you have an older house with wooden doors and/or windows that need some attention - then I thoroughly recommend Sealasash.

The team were very professional, polite and punctual. Thanks to their expertise, our rattling, rotten, draughty windows that would neither open nor close properly are a thing of the past. They left the site very clean despite having to stay late to finish the job.
