Gentlemen, I'm looking for some recommendations on types of insulation to use to insulate my basement ceiling after I have installed a pex radiant heat system under my kitchen. I have a lot of obstacles in the way such as joist supports, wiring, copper lines, etc.. I notice some of the bubble wrap type has different r values, I have see some as high as r-30. It looks like I'm gonna have a lot of cuts to make. Has anyone had any experience with a cluttered ceiling? TIA
