The National Fenestration Rating Council (NFRC) approved changes to its NFRC 100 and NFRC 200 standards, allowing certain shading devices to be rated for U-factor and Solar Heat Gain Coefficient. These changes apply to products that use shading systems (blinds, shades) that are integral to the product as shipped from the manufacturer, including dynamic attachments for swinging doors. Also included is dynamic glazing such as electro-chromic products and certain non-specular transmittance products such as frits, translucent fiberglass, and etched glass. These changes, however, do not apply to aftermarket items.
