Patent ID: 8561359

Claim:
A baffle vent for maintaining a passageway between roof rafters of a building for a flow of air from a soffit to a roof vent past insulation material installed between said roof rafters which are covered by roof sheeting, comprising: a main body portion having a first end and a longitudinally spaced second end defining a longitudinal length of said main body portion, said main body portion further having first and second transversely spaced sides defining a width dimension of said main body portion, said main body portion being formed with a plurality of longitudinal ridges and valleys extending between and terminating at said first and second ends, said valleys providing a flow path for said flow of air past said insulation material, said ridges providing longitudinal stiffness in said main body portion to maintain said flow path; a drift blocker portion having, third and fourth ends spaced longitudinally from said first and second ends of said main body portion and further having opposing transversely spaced side edges defining a width dimension of said drift blocker portion wherein the width dimension of said drift blocker is smaller than said first width dimension of said baffle vent panel and wherein said drift blocker being formed of a shape devoid of ridges and valleys to permit movement of said drift blocker relative to said baffle vent; and a flexible transition portion interconnecting said second end of said main body portion and said third end of said drift blocker portion to permit movement of said drift blocker portion relative to said main body portion, said transition portion being connected to each of said ridge and valley at said second end of said main body portion when the drift blocker portion is positioned angularly with respect to the main body portion and having a longitudinal length sufficient to join to each of said ridges and valleys corresponding to said width dimension of said drift blocker to provide an impermeable barrier between said drift blocker and said main body portion along said width dimension of said drift blocker while allowing said drift blocker to be moved relative to said main body portion without requiring modification to said baffle vent.
