Joto-Vent System Overview
Joto-Vent System Overview
The Joto-Vent System consists of 2 or 3 parts depending on whether you have an adjoining garage. The Joto-Vent and the Joto-Vent Architectural-covering are always required and meet the minimum opening requirement of 1/8-inch (3.2 mm) in IRC's Section R408.2. The Joto-Vent Air-blocking is used to block the air when the crawl space is built next to the garage to eliminate contaminated air flow into the crawl space.
The primary component of the Joto-Vent System is placed between the concrete foundation wall (2 x 6 or 2 x 8) and the wooden sill plate to provide natural airflow around and through the entire perimeter of the home’s crawl space.
The Joto-Vent Architectural Covering acts as the cover for the Joto-Vent and the seat for the exterior wall sheathing.
Air-blocking is an optional accessory for the Joto-Vent System which is used to create an air barrier between the garage and the crawl space.
