I'm not looking online.
There is a guy here in town who is leaving town who has a bunch of the audimute and offered to sell it to me cheap. He doesn't want to take it with him.
I've already bought part of my Knauf (OC 703 equivalent) locally. I couldn't buy all that I needed in one trip (filled the car). AFTER I bought some of the Knauf, I got the offer for the audimute.
So the question is whether to go back and get the rest of the Knauf, or use the audimute that is about 1/2 the cost (based on what he offered it to me for) of what I would pay for the rest of the Knauf.
I plan to have panels that are 4" thick with 4" airgap. If I go with the audimute I could buy more of it, so I could potentially make some 6" traps, too.
My Knauf is 2" ( they didn't have 4" ) and the audimute is 2". So - the question is whether 2" Knauf (faced) plus 2" audimute (unfaced) is the same as 2" Knauf (faced) plus 2" knauf (unfaced).
I bought the faced Knauf first.
