Expanding Foam and Radiators
I'm a newbie, and hopefully not a really stupid one. Let's find out:
In an effort to help out my friend who just moved into a new apartment, I offered to seal the gaps around the pipes for the two-pipe radiators in the flooring. Some of the gaps were gaping 3" holes, others about 1/2". None of them still had the caps intact.
I told her I'd use expanding foam. She ran it by the landlord, who approved.
Now, I used "Great Stuff™", but I had just grabbed the one at the end cap at Home Despot, and didn't know there was a higher rated one available.
I see on the can that it says it can combust at 116ºc. That's 247 Fahrenheit, and I know water boils at 212 Fahrenheit under normal pressure.
The two-pipe systems are water radiators, not steam tho, right? The steam ones have those little bleed nozzles?
I ask, because I've already put in the foam and am now having doubts about whether or not I've endangered my friend.
Can anyone knowledgeable please tell me approximately how stupid I just was? (and if I need to go back there tomorrow and somehow remove the stuff before she turns on the heat?)
