Hi Frank, No surprise you didn't find them in a building store. A lot of the really high performance building products you'd find in Passive House or LEED homes are trickier to find. So you are best to source them online and they get shipped directly to you. And, I woul say it really is worth it. The solvents in lower-quality building tapes that you easily find (which are used in almost all tract home developments) evaporate in pretty short order, at which point they become brittle and come unadhered.
