NFRC - 100 is used for which of the following purposes?

For evaluating fire retardant combustible materials
To provide standardized methods for testing flame spread of roof coverings
As a guide for handling asbestos removal in residential construction
When determining U factors for doors

The correct answer is: When determining U factors for doors

The NFRC 100 is specifically developed to provide standardized methods for determining U-factors, which measure the thermal transmittance of windows, doors, and skylights. The U-factor is crucial in assessing the energy efficiency of these building components, as it indicates how well they insulate against heat loss. This standard outlines the testing procedures necessary to ensure that the U-factors are reliable and consistent, enabling architects, builders, and consumers to make informed decisions regarding building materials. The other options focus on unrelated subjects such as fire retardance, flame spread, and asbestos removal, which do not pertain directly to the purpose of NFRC 100. Hence, the primary objective of NFRC 100 distinctly positions it within the realm of thermal performance assessment rather than the other areas mentioned.
