[Greenbuilding] translucent material needed

[Nick Pyner]

I can barely believe what I'm reading but, if bubble wrap even comes 
close to an answer, you might also look at using 3M heat shrink window 
insulation film, which you can actually see through, and know what's 
happening on the other side. It is actually made for the job you 
describe and is only about $20. I got mine from some outfit in Canada. 
The small door pack is probably more than you need.  My brother got 
worthwhile results by simply taping it to the aluminium frames, but I 
made up a timber frame out of 15x40 with foam surround which slides 
snugly into the timber reveal, and also makes it portable. The 
thermostat activity is a good indication of its effectiveness.  We need 
the window openable most of the year, so I made an envelope from foil 
insulation to store it in.

If you live in a seriously foul climate, I imagine it would be quite 
practical to put the film on both sides of the frame and suffer no 
evident loss of transparency. It does not appear to attract dust, and 
can survive a cockatoo flying into it without damage.

I submit it a pretty good long-term proposition as cheapskate double 
glazing, particularly if you are not opening the windows.

I want good light but at the same time also want to add another layer on 
the interior side of the windows that might make the openings more 
energy efficient.
