I wasn't sure how to word my question and I think I might have even asked it before. But i want to seal the holes in the floor where the Baseboard heat is installed.
I looked at the dow good stuff but it is highly not recommended that you use it as it is highly combustable wet or dry, there fire block is not recommended as a fire block (Not kidding, check their website)
If i put my hand near the holes in the floor i can feel the cold basement air coming up, what do you recommend I use to seal the holes? Thanks
