The complexity of today's research laboratories requires a completely controllable environmental surrounding. Research facilities require carefully controlled temperatures, relative humidity, and moisture, and must be free of interference from air-borne sound, mechanical vibrations, and electrical sources. Also desirable are special power…

The testing plans, procedures, and results of an experiment are revealed concerning the thermal performance and variable factors of unvented double windows, their heat transmission and inner surface temperature. Data are given to help improve the design and development of standards for the thermal performance of windows. Building humidity, window…
