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.

An attic ventilation installation in a building having a series of parallel roof rafters, comprising: between each pair of adjacent rafters, an elongate wooden member extending perpendicularly to the rafters, each member having at least one circular bore therethrough, positioned to establish ventilating communication between the attic and the exterior of the building; a circular patch of screen pressed into each such circular bore, the screen being of slightly larger original diameter than the portion of the bore into which it is pressed, so that it bows inwardly in a springingly deformed configuration which securely locks it into the bore; and said bore including a second portion of smaller diameter than said portion into which the screen is pressed, providing an annular stop against which the screen is pressed.
