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 Install

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. Once your order is ready, we will send you a Ready for Pickup email with full collection details.  Please note: pickup is from Preston, Victoria — not Prestons, NSW.

Q: Why is courier delivery so expensive?
A: Because this is a long product, freight costs are higher than for standard parcel items. We know that is not the most exciting news of the day, and we are always working to keep delivery costs as fair and reasonable as possible.

Q: Why can’t I choose Australia Post?
A: This product is too long for Australia Post, so it needs to travel with a specialist courier that handles oversized items safely.

Q: When will my order be despatched?
A: Most orders are despatched within 2–3 business days

Q: Will I get tracking?
A: Yes. Once your order has been booked with the courier, you will receive a tracking number so you can keep an eye on its journey.  Please note: if your order includes multiple items, they may arrive in separate parcels at no extra shipping cost.

Q: When will my order arrive?
A: Your order will be delivered by a specialist courier for oversized goods. This is not an express service, so delivery times can vary depending on your location and the time of year.  Delays are more likely during busy periods such as winter, Christmas and end of financial year.

Q: Will my order be left if no one is home?
A: Yes. Standard courier deliveries are sent as Authority to Leave. That means if no one is home when the courier arrives, your parcel may be left at your address.  If that is not suitable, please contact us when placing your order so we can discuss other options.

Q: What if my order arrives damaged?
A:
Please open and inspect your order as soon as it arrives. If anything has been damaged in transit, let ecoMaster know immediately.  Damage claims must be lodged within 48 hours of delivery. After that window, we may not be able to submit a claim with the carrier.

Q: What if my order goes missing in transit?
A: If your order seems overdue, we will follow it up with the courier on your behalf. If it cannot be located, we will arrange a replacement.

Q: What if my order is stolen after delivery?
A: If your parcel is stolen after it has been delivered, please report the theft to the police.

Q: How can I reduce freight costs?
A: Oversized freight can be expensive, especially for items over 1.5 metres long. To help keep costs down, you may wish to:

  • Combine all long items into one order
  • Share freight costs with a neighbour
  • Collect your order from Preston, Victoria
  • Use a more central delivery address if you live in a regional or rural area

We know freight costs can be frustrating, especially outside metro areas, and we will always do our best to help you find the most practical option.

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.
