Abstract. Wooden walls made of logs are constantly exposed to the effects of weather and unfavorable climatic factors that cause accelerated aging and various types of wood destruction. Therefore, since ancient times wooden houses with external walls of logs, lagged from the outside with wooden cladding were wide spread in Russia.
In this work constructive solutions of the external walls of log houses with wooden cladding are considered. The cladding protects lagged walls from destroying influence of rain, snow, wind, alternating temperatures, solar radiation and other negative climatic factors. In the ventilated air interlayer between log walls and the cladding, favorable moisture conditions are created, ensuring the removal of vaporous moisture from the wall structure. Due to such a constructive solution, the durability of the wooden walls increased. Such constructive solutions of timber walls with cladding and ventilated air gap were applied in Russian wooden architecture since the 16th19th centuries and such a construction became a prototype for modern exterior wall with cladding made of slabs of natural granite, ceramic granite, cement tiles and with ventilated air gap, which are now widely distributed around the world.
Key words: wooden wall, wooden cladding, log, air gap.
