I'm at the point where I want to install some T molding for the transition from our main room to the bedrooms. I just took a look at the directions and they only show screwing the track into the subflooring. Right now I only have the moisture barrier down above the concrete subflooring, so I dont think I can just screw it down. I guess I was thinking I could glue it down, but this would require me to cut into the moisture barrier, which I'm not sure is a good idea either. I'm wondering how I should do this?
Update - Added picture of T molding pieces if that helps.
