Attic insulation around brick chimney

Posted by ranger481vs (My Page) on

Continuing to prepare my attic for blowing in fiberglass insulation. I have a large brick chimney in the attic and I'm not sure how I'm supposed to deal with insulation around it? Since it's brick can the loose fill fiberglass be blown right up against it or???

Thanks for the help!

Generally, the answer is no. Check your local and state building and firecodes for what's required.

You didn't indicate what the chimney serves but for a fireplace the code rule is usually 2" clearance to combustible materials but unfaced fiberglass is not combustible. If the chimney is not lined I would parge it where possible.
