Abstract: A roof ridge vent has a pair of opposed, spaced-apart, elongate strips of ventilation material providing ventilation passageways transversely therethrough and forms opposed longitudinally-extending sides of the vent. The elongate ventilation strips are interconnected by a plurality of supports extending transverse relative to the elongate ventilation strips. Each adjacent pair of supports defines an opening therebetween such that an underlying roof surface is visible to an installer through the openings. A vent assembly and method of installation are provided.

Abstract: A mortar and debris collection device for use within a cavity wall to prevent the blockage of weep holes at the base of the wall. The cavity wall assembly includes a masonry wall, an adjacent inner wall, a wall cavity therebetween, and a free-standing elongate strip of openwork material located within the cavity forming a debris collection surface a spaced distance above a base surface of the cavity. Preferably, the openwork material is inserted and positioned within the cavity after the inner wall and only a base portion of the outer masonry wall is constructed. Thereafter, the upper portion of the outer masonry wall is constructed and any mortar or debris falling into the cavity is caught and supported on the debris collection surface.
