Sealant for around central heating exhaust

Scruff · 2010-01-12 12:30:22

Is there a sealant i can get to put around the exhaust outlet of my gas boiler in my kitchen? Just noticed that there is a big draft coming in from around the pipe. If there was a foaming sealant that could do the job that would be better because its a bit on the awkward side to get all around it. Cheers.

If its a gas boiler is most likely twin wall flue. ie the outside is cold to touch. (Not the exhaust outlet)So really you can use any sealent. I would use silicone though. An all weather sealent and a caulk on the inside so you can paint around it.
