ABSTRACT:
Heat escape pipes for cinder block structures. A cinder block cavity cap is modified to have a central aperture formed therein. The aperture is specifically configured and dimensioned to receive the base of an upstanding vent pipe. The modified cavity caps are installed in the conventional manner, i.e., they are positioned to cap the cinder blocks in the penultimate row of blocks. The vent pipes are of sufficient length to extend above the concrete which is thereafter poured into the void of the top row of blocks, which concrete is prevented from entering the voids in the blocks below the top row by the cavity caps. Hot air escapes through the vent pipes since the respective lowermost ends of the pipes extend through the respective apertures formed in the cavity caps to thereby provide communication between the interior of the wall and the exterior of the wall.
