    Abstract

    Industry standard tests and calculation methods under laboratory conditions are used to determine a Condensation Resistance Factor (CRF) for window frames. The CRF is one of several performance parameters used to select fenestration products for specific conditions of exposure and occupancy. Colder climates and higher interior humidity typically require fenestration products with higher CRFs. The CRF by itself is not necessarily a predictor of the ability of a window frame to resist interior surface condensation due to thermal bridges or breaches in thermal breaks created by installation details, rough opening materials, and surrounding wall details. This paper explores the affect of installation details on the interior surface temperature of metal window frames, and indirectly, the likelihood of surface condensation on the frame.
