Thermo-optical properties of construction materials are im- portant factors while designing a building. Human comfort and environmental issues are the main reasons inciting re- searchers to work in this field. For instance, the thermal con- ductivity coefficient, the optical reflectance, the optical trans- mittance and the optical absorbance of materials are fre- quently measured properties in civil engineering. Currently, each of these physical coefficients is measured separately by various devices. A new experimental device is therefore de- signed to measure these properties in a single unit. The data presented in the article consists of the experimentation pro- cess of designing a new type device. This paper includes data for calibration, measurements and validation for the el- ements of the new device. This data has been collected in the laboratory and is made available for reproducibility and improvement research in the field of thermo-optical proper- ties of construction materials. This data article is related to the original research article of Fakra et al. denoted “A new simple experimental device for measuring the thermo-optical properties of translucent construction materials.
