Quality control of installation at the site

The advantages of real wood are:
- high strength and low wood pulp (for the most types Yo<1000 kg/m³), that accounts for high coefficient of constructive quality;
- low heat conductivity;
- low sound conductivity;
- high frost resistance;
- low coefficient of temperature line expansion.

Wood can be divided into softwood and larch. Softwood is widely used for wooden window production, because it is easy in drying and processing and has low heat conductivity. Pine has fewer knots than whitewood and so is easier in processing. Whitewood, in comparison with pine and larch contains less tar – natural antiseptics that don’t let wood rot. The most popular of larch are oak, larch, mahogany and others. Compared to softwood oak is firmer, but has higher heat conductivity.
