Metal ducts under my house had a fiberglass based insulators that are
falling off and now the ducts are sweating.
I am planning to install a foil based (Reflectix) insulator coming
I am thinking a "linear pipe wrapping" approach using 24" wide
My question is: What is a preferred method to hold the insulators
together around the ducts. I can think of staples or tapes....
Thank you for your advice.
