The National Fenestration
Rating Council (NFRC) announces the publication of two new technical
interpretations.
The first, known as TI-2012-04, explains how to simulate a sliding glass door
with a single, horizontal mid-rail. The second, known as TI-2012-05, explains
how to model a four-panel center-parting door system as a two-panel door with
one fully modeled panel/frame section and one center-lined modeled
panel-to-panel section to serve as the opposite door jamb.
Read both interpretations here, and let others know what this means to your business.
