Wood Underlayment

This 10 mm thick black rubber pad is our under-bamboo soundproofing. It's also from Sound Isolation Company. Wood floor soundproofing requires different materials and since our subfloors are ply wood and not concrete, we need a thicker pad than someone might use in a new high-rise condo. The pad is made from 93% post-consumer waste like as tires and old dodge balls. It's extremely heavy. One 4' x 25' roll weighs over 200 pounds, and we'll use close to 5 rolls. That's half a ton of soundproofing on our kitchen and living room floors.

Thanks to Matty Cat for lending us his heft this evening. Matt and Justin lugged these things up unfinished deck stairs and it was precarious, if not somewhat dangerous moving the behemoth rolls of rubber. We'd also like to thank Matt for his help a few weeks ago hanging insulation in the basement bedroom ceiling. (That too, was a soundproofing project.) Matt and Karen have been a huge support to us through this project and we'd be filling our milk with tears without them.
