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.

There are 3 steps to installing ecoGlaze. Each step is detailed in a separate video. It is essential you watch all 3 videos before you begin your order in readiness to DIY install.

Step 1.

  • Estimate - determine the number of ecoGlaze fixed sets you will need before ordering.


Step 2.

  •  Measure all the lite dimensions accurately and cut each ecoGlaze component to size.


Step 3.

  • Fit the ecoGlaze to your lites.
  • 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. 


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.

Q: What is DIY ecoGlaze and how does it work? 
A: ecoGlaze is a secondary glazing system developed in Australia that is now available to DIYers who wish to achieve the benefits of double glazing without the cost, time investment, disruption or hassle.

By adding components (a spacer, mouldings and clear sheet acrylic) to the inside of your existing windows, you create the still air space that is what makes double glazing work - for a fraction of the cost of replacement double glazing.

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 and double-hung / sash windows has been released.  ecoGlaze for double hung windows will be released in 2024.   

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 viable. 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.  We are not anticipating a release date for this product before winter 2024. 

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.


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: All over-sized orders are picked, packed and despatched within 3 business days.  It 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 the specialist courier varies depending upon the delivery location.   Clearly delivery times will fluctuate at peak shipping times such as Christmas.

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 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!!
