Hi,
My insulation arrived today and decided to put it to a test...
Bought a cheapo toaster oven a while back that has so little insulation I can heat half my house just by cooking a small pizza in it,(on sale at Walmart and couldn't resist).
Warmed up oven to 400 degrees F, reading on glass was 320. Placed insulation approx. 1" away from front and secured with bricks. Let soak for 30 minutes and made another reading,(ambient temperature in kitchen was 76).
Four degrees difference seems pretty good to me.
Thanks, David
