EXPERIMENTAL STUDY OF THERMAL-PHYSICAL PROPERTIES OF A DOUBLE-GLAZED WINDOW AND PLASTIC PROFILE OF THE WINDOW BLOCK
N order to learn thermal-physical properties of a construction material it is necessary to learn its thermal conductivity coefficient λ, thermal resistance of heat conductivity R, heat diffusivity a. Loss of heat into the environment are caused by the external enclosures of buildings: double-glazed windows, plastic profile for double-glazed windows. To solve the problem of energy saving and decrease in loss of heat into the environment from external enclosures of buildings - a plastic profile for double-glazed windows, it is necessary to know heat conductivity λ, thermal resistance of heat conductivity R, density of a thermal stream q.
