FIELD: physics.
SUBSTANCE: device for measuring heat-transfer resistance of a building structure has a heater and a first thermometer mounted on one side of the building structure, a cooler and a second thermometer mounted on the opposite side of the building structure, and device for measuring heat flow through the building structure. The device is further provided with a heat-insulated detachable chamber which houses the heater, the heat flow metre and the first thermometer. The cooler and the second thermometer are built into a box which is provided with elements for mounting to the building structure.
EFFECT: high accuracy of measuring heat-transfer resistance of a building structure.
