Re: Sealing floor around hot water baseboard heater pipes

[Guest guest]

I used the expanding foam, once dried it has no odor and did not offgas. I think

it was called stuffit, I am not sure. One thing is that we put it into the whole

a few inches down and it would " crackle " when the pipes expanded alot. I used

that amount as we had a problem with mice and not that amount would be needed if

you were just trying to keep it air tight. I would be curious if others had

suggestions. We tried just insulation first but the mice could move it. Aluminum

foil would also work if you are keeping out air. Good luck~

should I use a high temperature caulk such as 3M's Fire Block sealant?

Would the brillo " thing " be air tight? If the expanding foam " crackled " with

the heat, I imagine it wouldn't be air tight. Perhaps I should try the aluminum

foil.

Thanks!
