Topic: Smart Energy - In the home / Insulating windows - something cheap for a sharehouse

Hey Mat,

The things measure all sort of stuff, and can also control things – control is alpha at the moment, but it does work.  I get a cold shower everytime it fails, which isn’t that often.

The human thermostat is perhaps the best I’ve come across.

One thing though- energy consumption may not work out, as its not like I have a thermastat-driven heater…so I would have to use the imprecise-yet-funciton Mat-thermastat to generate comparable results

Hey! I just figured out what you mean- Nath showed me.  I didn’t realize your little thingies measured temperature as well!  Sure, that would be cool.  How much do one of those thingies set me back?

It would be very sweet to monitor the change in energy consumption in your room before and after with a mini SEGmeter.

The new ones will be even smaller and cooler.

Oops, meant to say the name of the products are generally called “Windows insulation kits”.  

The products I ordered on Amazon are here: http://www.amazon.com/3M-2141W-Indoor-5-Window-Insulator/dp/B00002NCJI

I also ordered a infra-red detection gun thing, to help spot leaks in my room.

Update: As I told Sam (in person) I have found some products that can be used to insulate products.  I think there is no agreed-upon-term to use, but essentially they are window insulation kits, which used heat-shrinking plastic sheets together with double sided tape.

I have ordered several kits from the USA (I cannot find a supplier in Australia), and also set up a website for anyone else who wants me to order products on their behalf.

Website I setup I setup is http://panegain.com.

Definitely go the tape first, and cut the drafts, also tape over any ceiling level vents.  What you want to do is make the room as air tight as possible to reduce the drafty loss.

Curtain eh? Hmm…I was afraid you would say that.  I think I’ll still keep looking for some DIY plastic solution, as I’m willing to bet a satisfactory solution can be found…though may take some time.  Just don’t want to sacrifice being able to see outside…working from home can be dreary enough in winter!

I like the candle idea. And if I can just solve insulating a window cheaply, it would be worth something to a lot of other people. I’ll have to keep you guys posted!

Hey Matt,

Welcome to the SEG dude!  I presume you are renting right?

The best answer is the double glazing, which is going to be expensive – any way you look at it.

What makes the biggest energy loss is through drafts, I’ve often used a roll of clear box tape to seal around the edges of the window and stop air leaks.  Run a candle around the window frame before and after to check the goodness of your work.

Also then think of hanging a heavy curtain or blind.  With a good air seal and window covering the result will be as good if not better than double glazing – the downside is, you just won’t be able to see out!

Heya,

I was going to message Sam directly, but thought it probably makes more sense to share this question.

So, I’m living in a sharehouse where the windows are by far the biggest problem with keeping heat in the rooms in winter.  If I sit next to the window in my room, and you can feel the heat being literally sucked out from you and out through the window.  Usually I’ll just wrap myself in a blanket since it seems pointless trying to heat the room.

So my question: What is the best way to insulate windows (best in that good insulation/$)? I’ve asked around and came across a bunch of professional installations, but can see some problems:

1. Double pane: Expensive, since often requires replacing of window frames.  The price means I’d want to get some help from the landlord, which they may be unwilling to help with.  Might not be a problem for me, but could be for others.
2. Magnetic pane (magnets are placed around the frame, and then a plastic ‘pane’ is cut to size and placed on the frame): Expensive- cost was quoted to me at $300 m squared, so my room alone would be $1500 for roughly 5 m squared of window.
3. Shrink wrap (DIY kit where special sheet of plastic is placed on windows and then a hairdryer is used to shrink + stick the film to the windows): I assume its cheaper than the above options,  but having trouble finding a supplier in Melbourne/Australia. Also, I believe its not as good as double-pane-type alternatives, as I don’t think there is a layer of air trapped between the film and window.
