Fenestration Performance: 2
ASHRAE Chapter 15 fenestration U-factors (W/m²·K) for windows, skylights, curtain walls, and doors by glazing configuration and frame type. Covers single through quadruple glazing with air, argon, and krypton fill, low-e coatings at various emissivities, and all major frame materials. Source: ASHRAE Handbook Fundamentals 2021 Tables 4 and 6.
