Double glaze your timber windows, achieve huge improvements in energy efficiency and pay them off with the TAS Energy Saver 0% Interest Loan Scheme. 

Over 20,000 windows upgraded to date with 150+ verified reviews.

What is the TAS Energy Saver Loan Scheme?

This scheme provides 0% interest loans to eligible applicants, allowing them to fund the purchase price and installation of energy efficient double glazing for timber windows.

Brighte is the exclusive finance partner for the TAS Energy Saver Loan Scheme. This means that you could borrow between $500 – $10,000 and pay it back over 1 – 3 years at 0% interest. This makes the whole process easier with less strain on the hip-pocket.

By partnering with Brighte, we’ve made it even easier to upgrade your timber windows, with the latest high-performance glass by Sealasash.

We can double glaze your timber windows

Most timber windows were originally made with very thin, fragile glass.

This is not only a massive source of energy loss, but also a security and safety risk if the glass is broken.

We can reglaze your timber windows, adding the latest high-performance glass that will provide an amazing new level of comfort, noise reduction and energy efficiency for your property.

The installation process includes our high-quality draught seals which stop the outside air and noise leaking through the window frames

Modern Comfort

Bring the comfort of your home into the 21st century

Energy Efficiency

Save on the rising cost of your energy bills​

Reduce Infiltration

Keep noise, dust and the weather outside​

Perfectly Smooth

Effortlessly open & close, with no annoying rattles​

Choose from three different types of glass

We offer three different types of glass, selected to 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.

Vacuum Insulated Double Glazing

Glavenir by Panasonic

With a very slim 6.1 mm profile, Glavenir fits perfectly into wooden window frames without compromising design, heritage, visual appearance or operation.

Developed by Panasonic, Glavenir vacuum insulated glass achieves better performance than triple-glazing because of the revolutionary vacuum design.

Frequently Asked Questions

We repair timber windows as a part of the installation of draught seals and new glass, we often call this an overhaul. Typically we do not build new windows or undertake major repairs to timber rot or damage – we can refer you to a specialist service for this if needed.

We only work with timber or wooden windows.

This includes double-hung sash windows, casement windows, awning windows, fanlights, pivot windows, horizontal Yorkshire sliders and fixed windows.

Yes, we can install the high-performance double glazing into your timber windows.  We offer three different types of glass, which have been selected to suit the different climates throughout Australia, which can actually achieve the same performance as a triple-glazed window if necessary in your area.

Over time, many old timber windows are rattly, draughty and stuck.  This can lead to an influx of outside air, noise and dust which makes them terribly energy inefficient.  Our high-performance draught seals protect you from the outside air, noise and dust.  As part of the process of installing draught seals, we’ll also make your windows slide open and closed with a light touch and silky smooth.

Whilst it might be cheaper to rip out your timber windows and replace them with new plastic or aluminium double-glazing units. You will instantly lose the character of your property and it will never look the same.  Keeping original wooden windows maintains and arguably increases the value of your property.

Replacement window frames can cause problems with other parts of the window opening. And they simply won’t look right.

Your old 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 last another 100 years.

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 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.
