Hi,
My contractor is proposing and alternative method to sealing the air conditioning ducts. They would like to use a foam for the duct end that would be air tight. Their concern is the plastic can rip and have holes in it. Do the SMACNA guidelines allow for alternative methods of sealing ducts? Thanks.

This is just my opinion, but I believe that as long as you show that the ducts are sealed, you can use whatever method you think is effective. I believe that it is a performance rather than prescriptive standard.
