I recently installed insulation (R13 rollout w/vapor retarder) in my attic around the chimney where there previously was none. I plan on using the fireplace this year, is there any risk of fire? Should I remove the insulation?

Thanks.

If you have a conventional brick masonry chimney, you should have no problems. I am not aware of the clearance required for tin chimneys. The temperature rise through the masonry is very low because of the thermal characteristics.

Fiberglass is not combustible, but the paper is. Your wood is probably tight against the chimney in places.

Yes, it is the traditional brick mortar chimney. I thought it was ok, but with not having used the fireplace until now, I wanted to be sure.


Thanks.

If you have never used the fireplace, I would have it cleaned and inspected. You never know how the last person left it.

Masonry is very forgiving, but you never know about Mother Nature or the other guy's actions.

It's scheduled for this Saturday. Definitely necessary, since I found trash bags the previous owner had stuffed up the chute to keep rain out.

Sounds like you could use a metal chimney cap to keep out the weather and make the chimney last longer.
