Solar Transmittance/Solar Reflectance Measurement
Measurements were conducted on four types of commercial plate glass to determine their respective visible transmittance, visible reflectance, solar transmittance, solar reflectance, and normal emittance
Solar – Glazing Options | Rationel Windows and Doors

Optical and Solar properties of glass and glazing
Solar energy incident on any glazed surface comprises light and heat. 55% of solar energy incident on Earth comprises heat and slightly over 40% is visible light. This simply means
A review of conventional, advanced, and smart glazing technologies
When the sun ray reaches glazing material, it is either transmitted, reflected, or absorbed by the glazing depending on its optical properties. Sun ray consists of visible, and invisible radiation

Glass & Solar Radiation
use low energy transmittance glazing, known as “solar control glass”. This glass allows only a specified fraction of solar radiation energy to pass through, providing illumination but helping to prevent
Energy Performance Ratings for Windows, Doors, and Skylights
U-factor is the rate at which a window, door, or skylight transmits non-solar heat flow. For windows, skylights, and glass doors, a U-factor may refer to just the glass or glazing alone. NFRC U-factor
