    Abstract

    The use of light and thick insulating materials (fibrous and cellular) is becoming more and more frequent. This led us to the building of a thermal resistance measuring apparatus equipped with large-size heat flowmeters. The construction and performance of such an instrument, which allows thermal measurements on light insulating materials of thickness up to 120 mm, are described.

    The apparatus, using one single specimen, is equipped with a bi-guarded hot plate and a heat flowmeter. This gives the possibility of performing both relative (with the heat flowmeter) and absolute measurements and of cross-checking the results.

    Such flexibility allows the study of some anomalies concerning the calibration constant of the relative measurement apparatus, which is being employed more and more in industrial quality control.
