The aim of the paper is to analyze structural systems of wood-based buildings and their applicability in the construction of apartment buildings in terms of fire safety. It also describes the optimization of the material base of thermal insulation and cladding materials in terms of fire and acoustic insulation and optimization of insulation and cladding materials in terms of sustainable development. The result is assessment of their suitable application in the construction of apartment building depending of the fire height and Comparison of their physical parameters in terms of thermal and acoustic insulation.
