I have *really* inexpensive carpeting in the basement that has a foam
backing. I am all set to have a friend with carpet-laying experience
come by to join the seam with the iron and glue. But then he asked
about the foam backing (apparently not something he ever dealt with
with better quality carpets).

Do we seam a carpet the same way with a foam backing (or will it melt?)
Or do we use tape or some other method?

TIA, Scott
