Plastic hood exhaust vents are exterior covers designed for home ventilation systems, like those for dryers or bathroom fans. They are typically made of durable plastic with a rain guard, a built-in damper to prevent backdrafts, and a screen to block pests. They are a cost-effective and lightweight alternative to metal vents.
