[QUOTE="Rudy, post: 5904714, member: 568035"] It's very hard to tell what that is from the description. The funniest line to me is: So their [I]nominal[/I] thickness is 3/1000th of an inch thicker than the other leading brands? Shiny isn't an important characteristic of foil, thickness is and they don't mention that. They've carried the 1 mil PSA claim over from FatMat. This certainly wasn't true for FatMat - the asphalt was the adhesive as it should be for a constrained layer damper. If they've actually taken some sort of cured butyl sheeting and applied a PSA it isn't a good sign. I'm sure they've gotten tired of people complaining about the asphalt and they seem to have mostly stopped claiming their asphalt products are butyl. The important thing is that an effective vibration damper is a very careful balance between adhesive formulation and foil thickness/strength. Butyl isn't automatically effective, it just isn't likely to melt. Not being likely to melt is about as low a standard as you can set. If you understand what you are selling, tell us about it. If not, just stop. [/QUOTE]
