Abstract
Abstract An epoxy-joined-and sealed weatherproof clapboard assembly comprising a plurality of interlocked clapboards which are adhesively joined along beveled mating surfaces and epoxy-coated on all weather-exposed surfaces, each clapboard having a beveled drip edge and a beveled shelter edge, whereby the epoxy coating forms a C-joint which grasps the lower or drip side of the clapboard rather than merely holding it in shear. Each clapboard is sealed with an epoxy resin on all surfaces before assembly and comprises an elongated panel to which a pair of inwardly beveled interlocking strips are adhesively attached along each long edge and on opposite sides of the panel. The upper holding interlocker is on the weather surface and adjacent to the upper side of the installed panel, and the lower sealing interlocker is on the interior or protected surface and adjacent to the drip side of the installed panel. Each panel is also provided with lap joints along its end, whereby the clapboards are adhesively conjoined end-to-end, and is preferably one-half inch thick.
