Hi, I searched through google and this site and many others for several hours and couldn't find any answers. My question is this. I bought my house 6 years ago and down in the unfinished basement there is very thick black plastic installed on the ceilings. There is no insulation above the plastic. What is it's purpose and if I wanted to finish the ceilings would I just put drywall right over the top of it?
Thank you,
