Baffled attic vents and methods of their use and manufacture are provided. The baffled air vent of this invention includes an elongated member having a roof facing side and an attic space facing side, a pair of longitudinal side portions, first and second transverse ends, and at least one central panel portion. The vent defines at least one channel on the roof facing side thereof, for directing ventilated air. The channel includes a bottom portion having an integral baffled surface thereon. The vent further has an installed, convective air flow reading, under a 5 Pa air pressure differential, of at least about 95 CFM. Further embodiments contain separation means for permitting the attic vent to be separated by hand in a transverse or longitudinal direction.

What is claimed is: 1. A baffled attic vent for ventilating air under a roof between a soffit area of said roof and an attic space, comprising: an elongated member having a roof facing side and an attic space facing side, a pair of longitudinal side portions, first and second transverse ends and at least one central panel portion; said elongated member defining at least one channel on said roof facing side thereof for directing said ventilating air; said channel comprising a bottom wall portion having an integral baffle surface thereon, said attic vent having an installed convective airflow reading, under a 5 Pa air pressure differential, of at least about 95 CFM said vent comprising a centrally located longitudinal rib having a roof facing side thereof, said roof facing side of said centrally located longitudinal rib comprising a plurality of undulated planar surfaces of alternating height, said integral baffle surface comprising a plurality of undulated planar surfaces of alternating height. 2. The vent of claim 1 wherein said elongated member also comprises a traverse support disposed substantially along at least a bottom wall portion of said channel on said roof facing side of said elongated member. 3. The event of claim 2 wherein said transverse support forms a portion of said raised baffle surface. 4. The vent of claim 1 further comprising a flange integral with each of said pair of longitudinal side portions. 5. The vent of claim 1 wherein said undulated planar surfaces are separated by defined steps. 6. A baffled attic vent for ventilating air under a roof between a soffit area of said roof and an attic space, said vent forming a duct with the attic facing side of said root said vent comprising: an elongated member having a generally "W"-shaped cross-section including a pair of longitudinal side portions and a pair of channels separated by a centrally located longitudinal rib; said pair of channels having first and second bottom wall portions, respectively; said elongated member further comprising an integral baffle surface disposed on a roof facing side of said elongated member, and a transverse support groove disposed at least along said first and second bottom wall portions of said pair of channels wherein said transverse support groove is disposed transversely across said elongated member, including across said centrally located longitudinal rib, between said pair of longitudinal side portions so as to provide transverse support to said vent. 7. The vent of claim 6 wherein said transverse support comprises a portion of said integral baffle surface. 8. The vent of claim 6 having an installed convective airflow reading, under a 5 Pa air differential, of at least 95 CFM. 9. The vent of claim 6 wherein said integral baffle surface comprises undulated substantially planar surfaces of alternating height disposed along said first and second bottom wall portions of said pair of channels.
