AccuVent® for Manufactured Homes


The popularity of modular homes has drastically increased over the past decade. Because this style of homes is built differently – from the bottom up – it calls for an attic ventilation product that can be placed on top of the rafters before the roof sheeting is attached. AccuVent for Manufactured Homes was specially designed and engineered for this application.

This system works in conjunction with a Drift Blocker to provide high-performance ventilation for manufactured and system-built homes. The Drift Blocker creates an insulation boundary and interfaces with AccuVent to direct air up and over the insulation blanket. Together, these pieces prevent insulation drift and allow for efficient air flow, eliminating costly problems with mold, ice damming, and staining.
