FP-10 One Way Roof Vent - Black


The FP-10 One Way Roof Vent is a solar operated, moisture/vapor venting unit designed to release and prevent the re-entry of moisture-laden air in new or existing lightweight fill decks and built-up roofing systems.

The FP-10 Roof Vent is manufactured from black polyethylene and is designed for use with typical built-up roofing and modified bitumen systems. For torch-applied systems, do not apply flame directly to vent.

The venting unit consists of three major components: A one-piece roof deck flange and body, a weatherproof cap and a silicone rubber valve. The deck flange is 10 in. (254 mm) in diameter, while the body has a base diameter of 41/2 in. (114 mm) and a height of 6 in. (152 mm).

As the sun heats the roofing membrane causing trapped moistureladen air to expand, the one-way valve is forced open, releasing the moisture into the surrounding atmosphere.

When the roofing membrane cools, the process is reversed. Cooler air in the roof assembly contracts, drawing moisture-laden air into the roof system. The one-way valve closes to prevent its re-entry. The one-way silicone-rubber valve also prevents the entry of snow and wind-blown rain.

The unit qualifies for all Johns Manville Peak Advantage Guarantees for total system responsibility

Industry practice recommends the use of one vent per 1,000 sq ft (93 m2) of roofing area for vapor pressure control.
