This makes it an ideal insulation material for use in areas that experience high temperatures.
Notes to the metal chimney fire clearance table above.
As listed where shown in the table above means that the acceptable fire clearance distances for those chimney types must match or comply with the manufacturer s instructions.
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.
Those clearance spacings are normally found in at least two locations.
As such it can be used to insulate a chimney.
