Does bubble-wrap work for insulating windows?
For $15, I bought a roll of 24" wide roll of bubble wrap, enough for three or four windows (I only wanted to do the lower windows).
On a single glass window with no storm window, it makes a big difference!
I also tried it on single-glass with storm and next on Argon-filled double low-E windows, on each one , the difference was less than the previous test. The difference on double-glass, Argon-filled double low-E window was almost too low to read.
Take-away:
- If you have single-glass windows, bubble-wrap can certainly help. At $15 for several windows, it is tremendous bang for the buck.
- If you have single-glass with storms it will help a little.
- If you spent $300 on Argon filled double low-E, don't bother to invest $15 to cover your Argon-filled windows with bubble wrap.
