New to me, anyway, and I could find nothing on the net.
Appears to be original to a late 1950s - early 1960s Chicago ranch, appears to be a 2x or 3x wall system, looking up the chase in the attic I could see what appeared to be an asbestos layer exposed for about an inch at a junction about 6" below the cap.
The clients HVAC contractor - who seemed on the ball - and was on-site at the time identified it as "Vitro-Vent", says it a 3x wall system with a ceramic coated interior pipe, and that at this age pitting of the ceramic material may be an issue.
Also said it was appropriately sized for the current 50K BTU furnace and 40K BTU WH.
Bob Harper? Anyone?
