Heat transfer coefficient measurement of building constructions using HOT-BOX method

Laboratory offers measurement of heat transfer coefficient using HOT-BOX method for windows and doors according to standard SRPS EN ISO 12567-1.

The apparatus is used for examination of building doors and windows. Specimen is positioned between hot and cold chambers. Temperature and speed of air inside chambers is regulated with goal of achieving steady state. After achieving steady state (time required for this process is at least 2 days), determination of heat transfer coefficient for whole installed element is conducted. Dimensions of specimen should be 1500 x 2380 mm.

The request for heat transfer coefficient measurement can be found on following link:
