Sizing for a StormShield

Single wall, liners and Class A insulated flue pipe need to be measured by its INSIDE measurement.

Typically... newer standard size insulated flue pipe will have a 1" thick wall.
Older insulated flue pipes will vary in their outer measurements.

Measure and give us a call if you would like help sizing for a Storm Shield.

Air cooled double and triple wall flue systems need an air cooled chimney cap.

Typically... the inner pipe of an air cooled system is for smoke and flue gases.
... the larger outer pipe(s) will vary in size depending on the air space between the pipes and manufacturers design.
This air space needs to be vented to insure the flue systems proper function.
