Instead, I should have wrapped my kitchen in bubble wrap.

What a fool I was!

wrap the outside of the house and watch the nieghbors looks on their faces:D

I just wrote a quick blog on this because its so easy and cheap to do and I think more people should consider it.

One question I did have though. It looks like AC_Hacker used the bubble wrap with smaller bubbles while the pictures on Gary's site look like he used the bubble wrap with larger bubbles. I'm wondering if the larger bubbles would be superior to the smaller ones? It also seems like AC_Hacker used two layers of bubble wrap versus Gary just using one. Anyway, things to consider and compare.

For my tests, I compared several different windows, the best one was a two pane double low-E, which has the heat reflective coating on the inside as well as the outside.

So when I took readings of the delta-T on that window, the difference was not enough for me (intuition, no calcs) to justify bubble wrap.

For me, the take-away was that the inside reflective coating does matter... a lot.

Thanks for this thread, I may have to try this. on the south side windows. One thing though... Do the bubbles block the solar radiation? Do you lose the benefit of the sun rays heating the contents of the room during the day?

I haven't measured it, but I'm sure that you'll loose some solar energy during the day.

I usually put plastic up on my windows, but this year 5 (of the 7) windows i cover I put storm windows on the outside (Menards) and so far, i'm getting no condensation on any of those windows (not sure that means i'm not still losing heat through them)...the remaining windows, i'm still getting a ton of condensation (where on cold days i have to wipe the windows down with paper towel). I haven't tried bubble wrap, but i have built simple wood frames and covered those with cheap 6 mil plastic and put those over the windows to eliminate condensation....but those were a little goofy looking, so i spent the money on the storms.

Any tips on where to likely find the bubble wrap ?
Tips on what businesses may have in in their dumpsters or where to find it would be appreciated, I have a few unused windows that could benefit.

I got mine at one of the big-box home remodel places, Lowes.

They were selling it a a packaging material. Not free, but pretty cheap, if you have any income at all (not a reliable assumption, these days).

I guess i could afford it :) not really a big ticket item haha but i am frugal.
(nice word for cheap)
If i had to i would buy it.
It seems so right to use materials that otherwise would get thrown away.
I will see what i can scrounge, I thought about using cheap blue laminate flooring insulation i can get from a recycler for a few bucks for a 4x100 ft .
I could tape it together with tuct tape make multi layers and staple it over the frame of the two large back windows, as I never open them up or draw the curtains with.

Its ridiculous really to have such a big 5ft x 6ft window in the bedrooms...

No need to explain. As a species, we are marching to oblivion and leaving mountains of trash in our wake.

Even smart corporations find clever ways to turn their wasted material into profits.

I'm not familiar with this material, but use it if you think it will work.

Dry corrugated cardboard makes a wonderful insulation. If you can put it together in layers that don't leak air, you'd really have something.

You really got that one right... you have a 30 square foot thermal hole in the wall, since a single layer of glass is R-1. And you spend your nights there, so view is of no value to you... horrible design.

Block it up, fill it up,
