Abstract

The purpose of this project is to research and develop a "Guarded Hot Box" type thermal conductivity tester used to determine the insulating properties (R-value) of construction materials and wall systems according to ASTM C 236-89 (1998). (See Appendix A) In this type of system, a construction material or wall unit is placed between a cold box and a hot box which consists of a guard area and a metering box. Mathematical equations for heat transfer and energy are used to solve for R-value. The design of the box is in accordance with ASTM C 236-89 which allows for the fixing of constants within these equations. The degree to which these constants are held are by the use of an advanced electronics console which controls temperature in the guard and metering box.
