A wooden log house is an energy-efficient construction. The heat losses in GREENO log houses are minimized, therefore the energy consumption is low. It is ensured by unique constructive solutions and heat steadiness of wood, which is at least 3 times greater than for brick, and 12 times greater than for concrete. If you touch wood by hand, it is not even cold in winter. Indoors wood absorbs excess moisture, releasing it into the air and quickly drying – the wooden house breathes.
