A bar consist from sift proof pine or fur trees, precise machinery processed.
2
Smooth surfaces.
House from natural profiled bar looks tidy and attractive.
3
Energy saving.
Profiled bar has 3 mm backlash with a sealant, wide “cold bridge”, difficult “labyrinth” lock with displacement in two planes.
Such house becomes considerable warmth. For example, 190x190 mm profiled bars equals to a 320 mm log and 240x190 mm to 420 mm log.
4
Economic.
You need 40 % less profiled bars than round profiled logs in volume.
Profiled bars are almost 2 times cheaper than square-profiled bars.
That’s why profiled bar is one of the most favorable building material.
5
Minimal cockle.
In house building the natural humidity bar is used. According to GOST a house from a natural humidity bar has only 3,5 % cockle for a pine/fur-tree (to exploitation damp 16-18 %).
6
Caulker’s iron is not required after cockle.
The lock design and sealants (heat insulator ) between teeth rows excludes blow-out and gives additional economy.
7
Water-proof walls.
The profile design prevents rain water flow between bars and gives additional protection from rotting.
8
Minimal cracks on lateral faces.
There is no wood without cracks, but cracks occurrence in houses from profiled bars is minimal because of stress removed from four sides of a bar.
