sealing holes in the floor (Forced Hot Water)
I recently had the heat in my house worked on, they installed all new forced hot water piping all over, they drilled holes in the floor and ran the piping up and its fine.
My question is, can I use the dow spray foam to seal around the piping? I'm trying to keep the boiler noise down from the basement, I know the pipes get hot and I wanted to make sure it is ok to use before i sealed the holes. Thanks
