Thermo-optical properties of construction materials are important factors while designing a building. Human comfort and environmental issues are the main reasons inciting researchers to work in this field. For instance, the thermal conductivity coefficient, the optical reflectance, the optical transmittance and the optical absorbance of materials are frequently measured properties in civil engineering. Currently, each of these physical coefficients is measured separately by various devices. A new experimental device is therefore designed to measure these properties in a single unit. The data presented in the article consists of the experimentation process of designing a new type device. This paper includes data for calibration, measurements and validation for the elements 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 properties 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.”  .
