Abstract:
1. A method of insulating a wall, the method comprising: providing a dynamic heat flow meter for measuring thermal properties of insulation, the dynamic heat flow meter comprising: a housing defining at least one cavity therein; first and second plates at least partially provided in the housing, wherein a test sample of insulation is to be provided between the first and second plates; means for providing the first and second plates at known, but different, temperatures when the test sample is therebetween; means for introducing an air flow into the cavity defined by the housing on one side of the test sample, and permitting air from the air flow to exit the cavity from the other side of the test sample; means for measuring thermal properties of the test sample using each of the air flow and temperatures of the respective first and second plates; and wherein the first plate has an air flow inlet aperture(s) defined therein, and the second plate has an air flow outlet aperture(s) defined therein; and causing the wall to be insulated using insulation based on thermal properties of insulation measured via the dynamic heat flow meter.
