The enterprise ODO SPP “Promtexresurs” deals with production and exporting to European countries of log hand-made houses. Within the past eight years we delivered our houses to Norway, Sweden, Austria, Hungary, France, Spain, Estonia, Latvia. The technology of building log houses of wood angular bars (lafte) has been used in Scandinavian countries for more than a thousand years.To manufacture our products we use pine wood. We take lumber 28-40cm in diameter and 12.5m long. Logs are sawn from two sides to make a bar (lafte) with a standard width 180 or 200mm. Each bar is of individual height ranging 270-380mm. In lafte production a natural narrowing of a log finds its use. The technology we apply allows a height differential along a log to be 1cm per every meter of length. After sawing a log is dried up to 20% humidity in a drying chamber and under a shed. For walls conjunction we use the technology of the “Norwegian lock” which has been widely used in Norway for several centuries. Norwegian lock provides a proper quality of log ties in adjacent corners. This is a kind of a self-wedging lock which ensures a faultless rigidity for the whole construction.
