    That's the stuff. Pretty much any sheet metal will work. I used a sheet of galvy stuff from the duct work section at Lowes. So 22 gauge or more should do it. Mostly just for the stiffness.

    Good that you are getting rid off that slammer install. How soon will you be installing the Matrix insert? For a temporary fix I would just stuff some Roxul in the damper area and make the block-off plate specifically for the liner that comes with the insert. Before winter it should not matter anyway.

    Bart I heard using galvanized sheet metal is not good, could release a nasty smell , please set me straight. I have a sheet that says galvanized on it in the basement I could use but thought I couldn't

    Block off plates don't get even close to the point where galvy off gasses. Galvanized is dangerous when you do stuff like weld it.

    "Exposure usually arises through hot metalworking processes, such as smelting and casting of zinc alloys, or welding of galvanized metals. If the metal concerned is particularly high-risk, then cold sanding processes may also cause it, even though the dose is lower. "
