Imperial VT0640 Roof Vent Cap

Product Description

The IMPERIAL VT0640 is a roof vent cap designed to terminate exhaust or intake ductwork at the roofline, keeping weather, pests, and debris out of the ventilation system. Built to the R2 Premium specification, it provides a durable, weather-resistant seal point for residential HVAC, bath exhaust, kitchen ventilation, or general mechanical duct runs. HVAC technicians and sheet metal contractors install this cap as the final component of a through-roof duct termination, ensuring the system vents properly without backflow or infiltration. At 3.217 pounds, it is a solid, full-weight unit suited to lasting outdoor installation.

This roof vent cap is suited for residential and light commercial applications where ductwork exits through the roof deck. Typical installations include bath exhaust fans, dryer vents, range hood exhaust runs, ERV or HRV terminations, and general supply or return vent penetrations. It is installed on sloped or flat roof surfaces as the exterior termination point of the duct assembly, protecting the duct opening from rain, snow, wind-driven debris, and animal entry.

Installation Notes

Installation is typically performed by a licensed HVAC technician or sheet metal contractor in accordance with local mechanical codes and manufacturer instructions. Shut down any connected fan or air-handling equipment before beginning work on the duct penetration. Ensure the roof opening is properly flashed and sealed around the cap base to prevent water intrusion. Follow applicable building and mechanical code requirements for roof penetrations in your jurisdiction.
