Cheapest way of Double Glazing your windows

Improve your comfort levels with secondary glazing at a tenth of the cost of traditional double glazing windows systems.

This is exactly what I am thinking and your video provided enough proof of my idea. Thanks

I had one single pane window in a closet that turen the closet into an icebox in the winter. I add a double wall polycarbonate on the outside. It's been fantastic. I started this because this window produced so much moisture from condesation there was a constant mold battle. This has completely stopped it. If it proves to hot in the summer, it is secured with wingnuts so can be easily removed.

Used opaque perspex sheets to block light coming through a window and reduce noise from outside. Worked quite well. Thought it might improve heat retention and it did so more than expected. Was inexpensive and fairly easy job with the added bonus of lowering my heating costs.

I would be very concerned with trapping moisture between the plastic insert and the original window as presented, otherwise it is a very good idea.
Two options to either reduce or eliminate the potential for trapped moisture problems would be to either drill a small hole in two corners of the plastic sheet to allow equalization in the created airspace, or else mount the acrylic panel so that is can be removed from time to time for cleaning.

Thank you for sharing your experience with us as there’s many people who I’d imagine are interested in this kind of project. What with the energy prices rising and most older homes in Australia were not built with any kind of double glazing. We live in a 1960s brick veneer with draughty timber windows and the cost of replacing the windows with Double glazed ones is huge.We are considering a retrofit DIY secondary glazing to existing windows.The glass on the existing windows is 2.8mm thick lol

I am going to use cable channelling which has a clip-on top. Then I can remove the sheeting if I need to. Also, the sealed channel will improve the insulation at the edges and improve the appearance.

thanks for the video mate, real informative. I guess the only issue is opening/closing windows so if you windows like mine, which are sliding windows, you can only do sections, which may defeat the purpose.

[marvinloreto]

Does this also help with noise reduction? Thanks

Very good video. I would be interested what the temp of the window would be if you added a low e film coating to the acrylic.
In addition a before and after blower door test to measure ACH at 50 pascals would be great.

You can even use this system for double glazing which i have done good results for noise condesation and heat retention

[bryanking]

So there is 16 mm gap between existing window and the acrylic sheet? And can you tell me if this reduces outside noise?

Where to get custom cut plastic sheets in melbourne?

So what did you do with regards to the windows that open? These are the ones which could bring down the temperature after a hot afternoon using cross ventilation during the night.

Thanks for your info.
I see you used 4.5mm thick panel. I'm considering using 3mm for my windows. Is there a reason why you chose 4.5mm as opposed to 3mm? Thks

Quote to double glaze eight windows to reduce traffic noise at my house was $23000. Am thinking the cost of materials using 10 sheets of acrylic or polycarbonate is under $4000 if i cut them myself.. the 16mm air gap is ideal for best insulation I am told. Am investigating further but going to install before summer.

What sealant/glue are you using to put the window in?

[kaemmili]

awesome !
questions : sound proofness = zero?
scratch proofness too?

[MT-tpmv]

I’m confused how this works

Is the channel attached to the windows with double sided tape and then does the acrylic sit in the channel or just stuck to it with tape?

[juliabouy]

What about old timber windows.how could you do this?

[etroqueen]

How do you do this with a sliding window?
