Applied Films [Note: Applied films factory-applied to glazing prior to fenestration product fabrication and installation are already covered as glazing options by ANSI/NFRC 100 and shall not be rated according to the procedure of Section 5.10 below.] Scope This section presents additional details specific to applied films. This section presents and references methods for determining specific applied films U-factor rating. Variations from Standard Product Lines None Variations from Standard Individual Products None Variations from Standard Simulation and Test Conditions Approved Center-of-Glazing Computational Program Approved center-of-glazing software shall be used to determine U-factor. Applied films shall be from the approved NFRC spectral data files with the International Glazing Database (IGDB). Glazing/applied film assembly shall be constructed in accordance with NFRC 304 procedure. The following reference glazing systems shall be simulated with and without the film installed: Single 3 mm (1/8 in) Clear; Single 6 mm (1/4 in) Clear; Single 6 mm (1/4 in) Grey; Double 3 mm (1/8 in) Clear/3 mm (1/8 in) Clear: 7 mm (1/4 in) air gap; Double 6mm (1/4 in) Clear/ 6 mm (1/4 in) Clear: 12.7 mm (1/2 in) air gap; and Double 6 mm (1/4 in) Grey/ 6mm (1/4 in) Clear: 12.7 mm (1/2 in) air gap. The position (surface number) of the film when installed on the glazing system shall be documented (i.e., #1 to #4). This will yield the matrix in Table 5-8 for each applied film and applied film position. Calculation of Total Product Rating The reference fenestration product with applied film U-factor shall be calculated as outlined below.
