The
National Fenestration Rating Council’s (NFRC) Board of Directors has
approved changes to the NFRC 100 and NFRC 200, allowing certain shading
devices to be rated.
The changes apply to products that use
shading systems that are integral to the product as shipped from the
manufacturer, including dynamic attachments for swinging doors.
Also
included is dynamic glazing such as electorchromic products and certain
non-specular transmittance products such as frits, translucent
fiberglass, and etched glass. These changes, however, do not apply to aftermarket
items.
