ABSTRACT:
A wooden vent block for use in construction to provide attic ventilation has patches of screen pressed into vent holes in the wooden member, in an interference fit. The elastically deformable screens are of an undeflected size slightly larger than the vent holes, so that they deform when pushed in and become springingly locked in place. At the opposite side of each hole is an air conduit tube press fit into that side of the hole, with the vent block angled in accordance with the roof line so that the air conduits angle upwardly into the attic. This puts the ends of the conduits above the attic floor insulation, so that the insulation never interferes with ventilation.
