Zeihl Chimney Fans
All our extension tubes are custom made to size, therefore elimination leaking joints and connections. Stretching one ends of the tube 3" overlapping the smaller and makes an airtight connection. That way the joined tubes will have a nice sealed fit. The connection works like the wirsbo plastic plumbing pipe.
Heartland Chimneys are made of polyethylene and foamed polyethylene.
We foamed our chimneys for a number of reasons:
- To minimize condensation
- To keep condensation from forming in the attic of the barn
- Foaming makes the product very sturdy and rigid
- Foaming also gives the inside of the chimney a smooth finish.
