This has been a debated topic in my office for a few days now.
Insulation around chimney in attic.
However if upon inspection.
I m just looking for some more ammunition for my arguement.
It is often installed in gaps around the chimney and flue to prevent airflow that can siphon the heat away from the interior of the building.
Fiberglass insulation is naturally fire resistant.
8 cut a piece of flashing to measure the circumference of the flue plus 6 inches.
As such it can be used to insulate a chimney.
A chimney flue passing through a second floor ceiling into an attic space.
This makes it an ideal insulation material for use in areas that experience high temperatures.
The projects recommended in this guide can usually be completed in a day or two and will provide beneits for years to come.
