At first glance, the block-house resembles the usual all clapboard, but between these two facing materials there are significant differences. House panels on the outside have a semi-cylindrical shape and after the completion of the cladding facade takes the form of a log structure. For this reason, they are used as a decorative imitation of wooden walls. The panels have a flat inner surface with ventilation recesses. Installation of block-houses is made by means of lock connection on type "spike-groove", and final fixing to a lattice skeleton is made by means of self-tapping screws and kleymerov. Traditionally, the block-house is used for finishing the outer part of the building, but in some cases it is allowed to use it for internal work. For the facades it is recommended to acquire wide and narrow internal space of the panel.
