A. Products of all types as defined in Table 4-3;

B. Products of all frame materials, including (but not limited to) aluminum, steel, thermally broken aluminum, wood, vinyl, reinforced vinyl, fiberglass, and plastic, used singularly or in combination, or products utilizing foam as a core material;

C. Products of all glazing materials, tints, and types, including (but not limited to) clear glass, tinted glass, stained glass, fritted glazing, etched glazing, sandblasted glazing, glass block, thin plastic films (internally suspended, internally applied, or externally applied), rigid plastics, and translucent fiberglass with or without any solar control, low-E, or any other partially transparent coating, and products with manufactured decorative opaque insulated glazing panels, designed for interchangeability with other glazing options;

D. Products with any or no gap width between glazing layers; E. Products with any spacer or spacer system between glazings, including (but not limited to) metallic, non-metallic, or composite spacers;

F. Products utilizing any and all glazing dividers, including (but not limited to) interior, exterior or between glazing grilles, muntin bars, true divided lites, or simulated divided lites;

G. Products with any gas-fill between glazing layers, including (but not limited to) air, argon, krypton, or mixes of these gases; H. Products utilizing shading or diffusing systems that are an integral part of the product as shipped from the manufacturer, including Dynamic Glazing Products;

I. Dynamic Glazing Products, such as but not limited to electrochromatic glazed products; and

J. Dynamic Attachment for Swinging Doors.

Products and Effects Not Covered

The following products and effects are beyond the scope of ANSI/NFRC 100 and shall not be rated in accordance with this procedure.

A. Fenestration products with shading and/or diffusing systems other than those listed in Section 2.1;

B. Thermal performance changes of a fenestration product over the course of time, i.e., long-term energy performance;

C. Issues related to water tightness, structural capacity, and air leakage;

D. Pet doors; and

E. Permanently attached louvers.

PURPOSE
