Guarded Hot Box Test Results
Actual 8’ x 10’ roof and wall assemblies are tested in the Butler® Guarded Hot Box to provide accurate insulating information, rather than theoretical data provided by most building product manufacturers. That means Butler® building systems deliver the energy efficiency they promise.
Knowing the actual thermal performance of the building envelope assures compliance to energy codes. Your Butler Builder® can assist you in providing extremely accurate estimates of thermal performance for Butler building systems.
A state-of-the-art computerized data acquisition system collects information from up to 300 sensors used to measure the temperatures, humidity, airflow, and the total energy consumed during the 3-day test period. The results are expressed as the actual U-factor performance of the assembly.
