Description

Turn your existing windows into energy-saving performers—without replacing a thing. 🪟❄️☀️

Non-opening windows might look solid, but they’re often quietly leaking warmth in winter, cool air in summer, and money all year round. DIY ecoGlaze Fixed is a smart, easy-to-install secondary glazing solution designed to dramatically improve the thermal and acoustic performance of your existing fixed windows—without the cost, waste, or disruption of full window replacement.

Made in Australia for Australian conditions, ecoGlaze works by adding a clear acrylic panel over your existing glass, using a discreet magnetic framing system that traps still air—creating an insulating barrier similar to double glazing. It helps keep your home cosier, quieter, and more energy efficient, while preserving the character of your existing windows.

How To

DIY ecoGlaze requires you to have good attention to detail and the ability to closely follow our step-by-step guide videos to achieve successful insulation.

This is what you will need to measure up, order, and install ecoGlaze:

  • A metric measuring tape
  • Sharp pencil
  • Clean microfiber cloth
  • Small amount of blue tack
  • Hacksaw with a new fine-toothed blade 

Your DIY ecoGlaze installation kit which includes:

  • 1 x purpose-made mitre box
  • 3 x 100 mm long spacers
  • 2 x adhesive tools
  • 2 x test acrylic sections 

You will receive full instructions and detailed ‘How To’ videos when you order, sent directly to your inbox.

There are 3 steps to installing ecoGlaze.
Each step is detailed in a separate video.
It is important that you watch all 3 videos before you begin. 

Step 1.

  • Estimate - determine the number of ecoGlaze fixed sets you will need before ordering (skip this step if you have selected the 'Ready to Go' kits. 

Step 2.

  •  Measure all the lite dimensions accurately and cut down each ecoGlaze component to size (if required). 

 

Step 3.

  • Fit ecoGlaze mouldings to your lites.

 

Fit your Acrylic Panel 

  • Remeasure as explained in the ‘How to' video for the acrylic panel.
  • Order the acrylic panel from one of our suppliers or your own local supplier.
  • When your acrylic panel/s arrive – treat them with the utmost care. Whilst acrylic is extremely durable and almost unbreakable it can scratch.
  • Install the acrylic panel as per the video instructions. 

 

Delivery

Q: Can I collect my order?
A: Yes you can!  A “Ready for Pickup” email will be sent to you when you order is ready to be collected.  Please click this link for the Click and Collect details.  Note:  this Collection Centre is in Preston Victoria, NOT Prestons in NSW. 

Q: When will my order be despatched?
A: Generally, your order will be despatched within 2 to 3 business days.    

Q: Will my order be tracked?
A: Yes!  When your order is consigned, you will receive a tracking number that will show you where your order is and its expected delivery date.  Track your order here

Please note: Orders with two or more items may arrive in separate parcels with no additional shipping charge

Q: When will my order be delivered?
A: Your order will be delivered by a specialist courier that specifically handles oversized items that cannot be delivered via Australia Post. 
Please note that this is a specialist courier NOT an express courier. Our experience with specialist couriers varies depending upon the delivery location.  Clearly delivery times will fluctuate at peak shipping times such as Christmas, end of financial year and the pinnacle of winter bleakness!

Q: Authority to leave?
A: The standard courier delivery option is "Authorised to Leave". That means that if there is no one home when the courier arrives, your order will be left at your address. If this is not appropriate, please advise when you place your order for alternative arrangements to be made.

Q: What happens if my order is damaged in transit?
A: Our freighters have very strict policies on the ability to claim on insurance if your order arrives damaged.  There is a 48 hour window of receipt of goods for ecoMaster being able to advise the freighters of a damage claim.  PLEASE ensure you have advised us IMMEDIATELY if an order has been damaged on arrival.  Open your order immediately and check.  Outside of the 48 hour window, we are unable to make an insurance claim. 

Q: What happens if my order gets lost during transit?
A: Occasionally we have had orders go missing. ecoMaster has solid procedures in place and photograph every order that leaves our warehouse.  If a delivery date appears to be beyond expectation, we will raise a query on your behalf.  If your order cannot be found during transit, we will send a replacement.  

Q: What happens if my order is stolen after delivery?
A: If your order is stolen from your home after delivery, please raise a Police report. 

Q: How do I make my freight costs cheaper? 
A: We hear you!  Oversized items are expensive to transport.  Any item over 1.5m long carries an additional $10 charge by the courier.   

Potential cost effective freight alternatives are:

  • Share the costs of freight with a neighbour
  • Buy all your long items (such as Draught Dodgers) in one order (a second tube going to the same address is free)
  • Collect your order from Preston Victoria 

If you live regionally or in a rural location, freight costs will be high.  Do you have an address in a town where your order can be safely delivered?   We also live regionally and understand the frustration with the high costs of freight!!

FAQ

Frequently asked questions

Q: Wow - this is all new to me, where do I find out A LOT MORE about ecoGlaze? 
A:
 Yes, it is exciting discovering that you don't need to be spending huge sums on double glazing to get the same benefit.  And yes, it is a big topic! 
So we have a whole website dedicated to it - www.ecoGlaze.com.au


Q:
What is DIY ecoGlaze Fixed? 
A: There are three different types of ecoGlaze, each designed for a specific type of window. DIY ecoGlaze Fixed is for “non opening” windows. 

Q: Why is DIY ecoGlaze for Fixed windows only? 
A: No.  ecoGlaze for awning (wind-out) windows, hinged windows and glass doors is available now.  ecoGlaze for double hung windows will be released soon. Please subscribe to ecoBites to stay informed of developments.

Q: Can I get the acrylic sheet directly from ecoMaster?
A: No. We tried to develop a cost-effective solution for shipping acrylic around the country. Unfortunately, the logistics of doing this across Australia made the option not economically feasible for our customers. We concluded that the most cost-effective way for you to achieve the benefits of double glazing for the lowest possible cost, was for us to provide the DIY ecoGlaze Mouldings Sets and you source the acrylic locally. We have several suppliers who understand the ecoGlaze system and are very happy to work with you to achieve the final result. 

Q: OK. I will source acrylic myself. What do I need to ask for?
A: Ask for 4.5mm thick clear acrylic sheet cut to size. Some brand names that your supplier may have include Plexiglas, Shinkolite and Perspex. Provided you ask for 4.5mm thick clear acrylic, they will all be suitable for secondary glazing. Plexiglass has a 30 year warranty while Shinkolite and Perspex have 10 year warranties.

Q: My neighbours can look straight into some of my windows. Can ecoGlaze help obscure the view but keep the light? 
A: Yes it can! When purchasing your acrylic panel simply ask for “Pearl” coloured acrylic. This is similar to frosting on glass. It still allows most of the light in but obscures the view. In some situations, you can use “Pearl” to obscure the lower parts of a double-hung window and leave the upper parts clear.

Q: I have Aluminium Sliding Windows. Can I ecoGlaze them?  
A: Not yet. We are working on a DIY solution for Aluminium Sliding Windows that will allow you to secondary glaze existing residential aluminium sliding windows and still allow them to open.  Please subscribe to ecoBites to stay informed of developments.

Q: Can I fit DIY ecoGlaze to the outside of my windows.  
A: Technically, yes you can. But we do not recommend it and we do not warranty the components if they are installed outside. 

Q:  I already have double glazing. Can I fit ecoGlaze as well so I get the benefits of Triple Glazing? 
A: Yes you can. To get the full benefit of Triple Glazing your home, it is important that the rest of your home is also up to the same standard of thermal and energy efficiency. That means, a very well-insulated roof, good quality underfloor insulation, wall insulation and most importantly, thorough draught proofing!
If we can relate that to a clothing analogy; there is little overall benefit in wearing a really warm jacket, if you are wearing shorts and thongs.
 

Q: Will ecoGlaze stop condensation on my windows. 
A: ecoGlaze will significantly reduce condensation on the windows and doors in your home. Condensation occurs because of the build up of moisture in the air and condensing at the coldest point in your home - at the dew point. This is because your windows are normally the coldest element in your home. If there is a build up of condensation, simply remove the acrylic panel, dry the glass and the acrylic then reinstate the acrylic panel.

If condensation in your home is an ongoing issue, it would be necessary to determine the source of water vapour in the air and deal with it. Sources of water vapour include, but are not limited to: gas appliances (burning gas emits water vapour and carbon monoxide), drying clothes inside, bathroom exhaust fans that are not effectively removing moisture and some clothes dryers. This is especially during winter when condensation issues can be at their peak.

What is ecoGlaze, and why is it a good alternative to double glazing?

ecoGlaze is a secondary glazing system that gives you many of the same benefits as double glazing—better insulation, reduced noise, improved comfort, and lower energy bills—without replacing your windows. It works by adding a clear acrylic panel to the inside of your existing window, creating an insulating air gap that helps keep your home warmer in winter and cooler in summer.

Do I have to replace my windows to use ecoGlaze?

Not at all! That’s the beauty of ecoGlaze. It works with your existing TIMBER windows—no need to rip anything out. It’s a much easier, more affordable way to get the benefits of double glazing without the cost or construction mess.

Will ecoGlaze change how my windows look?

Nope! ecoGlaze is designed to be discreet and neat. The acrylic panels are crystal clear and the frame options (timber or white aluminium mouldings) blend in beautifully. Once it’s installed, you’ll hardly notice it—apart from how much more comfortable your home feels.

Can I install ecoGlaze myself?

Yes! ecoGlaze is a DIY-friendly solution with clear instructions and step-by-step videos to guide you through the process. If you’re handy and confident with a measuring tape, it’s a satisfying weekend project.  If you could prefer for an ecoGlaze installer to install for you  please contact us for a referral to a trusted ecoGlaze technician in your area.

How do I know which ecoGlaze kit I need?

That depends on your window type! We have kits for fixed windows, sash/hinged windows, and even ready-to-go standard sizes. If you're unsure, our friendly team can help you pick the right kit for your window style.

An elegant solution

I am impressed with the ecoglazing. We used it on 3 windows, it looks great and is performing very well.
DYO works well if you pay attention to all the details provided (especially the measuring sheet and videos).
One of the windows is on a glass brick ‘window’ in a bathroom. I was concerned about possible condensation between the glass bricks and the acrylic ecoglaze piece- it hasn’t been a problem.
Impressive!

Hi Trevor,

We are delighted to hear that it was an elegant solution for your windows and that you found our instructions and videos helpful. It's great to know that the product is performing well and that you were able to successfully use it in a unique situation, such as on a glass brick window in a bathroom. Thank you for your trust in our product and for sharing your feedback with us and the community.

Eco Master are impressive for Double Glazing

I have now completed 7 windows adding EcoMasters double glazing system. The system is quite economic and within normal handyman skills for static windows. The 3 YouTube videos explaining the DIY phase are priceless- they cover it all!

Hi Alan, you just made our day!!
Thank you for taking the time to provide such wonderful feedback. We are so delighted that you rate our ecoGlaze products and videos as 5 star. We do strive to provide that for all our customers. We look forward to seeing you again soon!
