Light Reflectivity – Why it’s Important

All light reflectivity values listed are based on a percentage system, the higher the percentage (eg. 20-24, 35-39), the higher the light reflectance of the floor. Research indicates reflectance can help capture daylight and reduce reliance on artificial lighting, resulting in reduced electricity usage and costs. Flooring in lighter colors with a matte finish have high reflectance values, but do not add to glare.

Brightness and quality of light play an important role in the illumination of institutional, commercial and industrial facilities. The light reflectivity ratings of resilient floors are important when taking the complete interior environment into consideration.

Since a majority of resilient floors are made of combinations of different colors, these light reflectance figures are average values based on a large area of the pattern. (Light reflectivity values are determined by measuring the percentage of light directed at any surface that is then reflected under standardized test conditions.) The Illuminating Engineering Society of North America recommends that floors have a reflectance factor of 20% to 40% for optimal seeing areas in offices, 30% to 50% for school classrooms, and 20% to 30% for hospital operating rooms.

Light reflectance should not be confused with gloss. Gloss can result in reflected glare from highly polished surfaces in the field of view. While gloss level depends primarily on the floor polish used, light reflectance depends upon the inherent color of the flooring material. Measured under incandescent illumination (ASTM E 1347). Types and patterns tested here are those most suited to commercial interiors where reflectivity is a major factor.
