Thanks. I don't know what the standard is in the US. The HVAC tape here (or on Amazon) does not generally say whether the adhesive is conductive. I have two rolls from different mfgs...and one is one is not. We *should* have such a standard, but I guess that means we may not.

Meanwhile those are much better prices than the last time I looked. It's about twice the cost as alu tape, but double the cost is still pretty cheap...and since it says it has conductive adhesive you know what you're getting.
