• The logs are presented in 3 sizes in width and 2 in height - as illustrated in the gallery above.

Available Log Width - 6,4”; 7 7/8”; 9,45”; (160; 204; 240 mm) - price is given for 6,4” (160 mm) thickness option. 7 7/8” (204 mm) - optimal solution for year-round living in the middle climatic zone, in terms of the ratio of cost and energy efficiency. 9,45” - is for the most frosty and windy regions, like north of Canada or Syberia. No additional wall insulation needed for all options.

Available Log Height - 7 3/32"; 10 5/8”; (185; 270 mm) - price is given for 7 3/32" (185 mm) height option. Higher logs are used in bigger houses, where the larger size of the log correlates more with the scale of the building.

The U-value for the calculated beam wall is 0,585. It means, that 7 7/8” (200 mm) thick laminated timber wall is equivalent to an 31,5” (80 cm) brick wall)

Cutting of material according to the project design, with the cutting of the end grooves, with protective finishing of the ends, ready to paint.

Internal walls are made in a framed design - to reduce the final cost and the possibility of various interior finishes. The use of beams for interior walls is an option, and is available at an additional cost. In this case internal finishing won’t be needed - which is lowering final cost and speeds up moving in.
