Finally tried that radiant barrier stuff in my attic last summer
I was real skeptical about putting aluminum foil up there, figured it was just marketing hype. After a 35 degree day in Calgary, my upstairs was 5 degrees cooler than before. Now I'm a believer, has anyone else tested the temp difference?

Honestly, did you measure the temp difference on the same days or was it just a one off? I tried it too and barely noticed a change of maybe 1 or 2 degrees, not 5. I think a lot of it depends on your attic insulation and airflow.

Buddy tried it and said his thermometer barely budged.
