Abstract
Abstract Heartwood cores, remaining after cutting veneer sheets from logs are sawn to provide half logs which are secured to a supporting structure to simulate a log building. The half logs are rabbetted at their edges and filler strips extend into the rabbets of adjacent half-logs. Each filler strip has an outwardly extending head wedged between acute angled edges of adjacent logs to provide an efficient weather seal.
