-The last and probably the most important plus is the highest environmental friendliness and fire safety. Frame houses are built of a wood array, and heater, in turn, consist of non -combustible and non -toxic components. On the health of residents, this building and the materials used in the construction process will not affect. The design I described is durable and the highest level of comfort. And one more pleasant moment: before the start of processing and assembly, all parts of the structure are treated with antipyrens. Antipyrene — a special fire -retardant composition, which is also environmentally friendly and does not affect human health. The wood impregnated with this composition becomes unavailable for combustion. Therefore, you do not have to worry about your safety and the safety of your loved ones.
