Detection Device and Method for Thermal Insulating Properties of Exterior Windows of Building

In order to assess thermal insulating properties of exterior windows of building objectively, a detection device for thermal insulating properties of windows was designed scientifically according to the requirement of national standard. The design plan of detection device was introduced. The detection principle of the device and the calibration method of the system were discussed, and the error analysis for the result was also made. Accurate quantitative-detection of thermal insulating properties of exterior windows of building has been achieved, which provides an important technical safeguard for energy saving of building.
