Emissivity values were measured at 0°C for four modern building materials in the 2.5-5.6 μm region of the infrared spectrum. The materials consisted of various visible colors and textures of roofing shingles, fluoropolymer coated steel roofing, aluminum siding, and solid vinyl siding. The results varied significantly over the range of colors selected. Values for thin coatings on metal substrates were lower than expected for the coatings alone. The effects of temperature, texture and wavelength were not clear. Emissivity values for common building materials were compiled from the literature and are included for comparison.
