I quick one this evening, just for the sake of generating content and developing good habits.
I was at the Home Depot a month ago buying supplies for a small HVAC project. In the midst of looking for proper adhesives and binding substrates for some flexduct and associated boots, I could almost NOT find the appropriate code-approved tape and mastic and webbing and ties. Sheesh, it was a battle. Nearly all the tape they had in the aisle was not code approved and probably would have lastly a hot minute on that cold duct (or vice-versa).
After 5 minutes of careful examination, I find it at the bottom right corner of an array of shiny foil nothing tapes.
Disappointment reigned. While code-approved tape probably have more to do with fire=rating than actual adhesive performance, nevertheless, complying with code should not be so hard. Having ductwork that won’t leak in 1 year wouldn’t be so bad.
On the bright side, as long as folks keep using hat crap, I’ll have more of a retrofit marketing plan
There are a wealth of reports and studies about this, but for the n00b: http://www.lbl.gov/Science-Articles/Archive/duct-tape-HVAC.html
