Abstract
Abstract A vent and baffle used to provide an air passage between the soffit and the attic of a house to insure the flow of air through the attic. The vent is an elongated arcuate member having outwardly directed flanges adapted to be secured to the roof boards of a structure with suitable fasteners. A first baffle is a block having a semi-circular recess to accommodate and support the one end of the vent againt the roof boards. The baffle is located in a tight fit or wedged relationship with the roof boards, adjacent roof rafters, and top plate of the structure to block the passage below the vent between the attic and the soffit and insulate the area above the top plate of the side wall of the structure. A second baffle is used without the vent to block the entire space above the top plate between adjacent roof rafters. The vent and baffles are made from a foamed plastic having flame resistant additives.

Total Claims: 22
Claim 1
Independent Claim
146 words
A vent and baffle for providing an air passage between the soffit and attic of a structure having a top wall plate, roof rafters, ceiling joists, and a roof cover secured to the roof rafters comprising: a vent having an elongated body, said body having opposite longitudinal sides and an arcuate shaped cross section forming a longitudinal groove with open ends, and outwardly directed side flanges secured to and extended along said opposite sides of the body; a baffle having a top arcuate recess and side pockets for accommodating a transverse portion of the body and side flanges, said baffle having a bottom portion engageable with the top wall plate whereby the baffle holds the side flanges of the vent in engagement with the roof cover so that the groove of the body forms with the roof cover an air passage between the soffit and attic.
Claim 2
Dependent Claim
146 words
A vent and baffle for providing an air passage between the soffit and attic of a structure having a top wall plate, roof rafters, ceiling joists, and a roof cover secured to the roof rafters comprising: a vent having an elongated body, said body having opposite longitudinal sides and an arcuate shaped cross section forming a longitudinal groove with open ends, and outwardly directed side flanges secured to and extended along said opposite sides of the body; a baffle having a top arcuate recess and side pockets for accommodating a transverse portion of the body and side flanges, said baffle having a bottom portion engageable with the top wall plate whereby the baffle holds the side flanges of the vent in engagement with the roof cover so that the groove of the body forms with the roof cover an air passage between the soffit and attic.
