It’s July 4, 2008 and we have to go to Home Depot. While we're there we check

So the next time you see plain foil tape, it means a contractor was saving
three cents a foot.

Don’t you wonder what else he felt he had to do to make a profit?
Comments
(01) Aluminum foil tape; it's the real McCoy, complete with red printing to certify the
extensive testing done on 181 tapes.
(02) Plain aluminum foil tape; package has a UL label and advises "As For Surface
Burning Characteristics Only" (a limited number of tests were run).
(03) Red cloth tape, the cheapest Nashua tape we saw.
