Soffit Suggestions....and drywall
I am gutting an old basement (paneling walls and sheetrock ceiling). I plan on installing sheetrock on the walls and the zero clearance "drop" ceiling I saw at HD that does not require lowering because the holders attach to the joists.
But I have some duct soffits. Do you recommend installing insulation in the soffit? I have very low ceiling and want to minimize the effect. Currently, they have some 1X2 stock as the soffit framing. If I use insulation, it would not really fit in the current soffit. Someone said to use liguid nails and glue foam board the ducts? Is this OK. Any suggestion? Do I even need insulation around the ducts being there was not there now.
Also, Is drywall OK in a basement? Someone said to use Denshield because it is more water resistent. My basement is dry, but can have a damp feel at times like most basements do, so I use a dehumidfier in the summer.
