CR

Condensation Resistance (CR) is an optional rating that manufacturers can elect to list on their NFRC label. It is expressed as a number between 1 and 100, and rates the ability of a product to resist the formation of condensation on the interior surface of that product. The higher the CR rating, the better that product is at resisting condensation formation. The biggest factors influencing this rating are the U Factor & the spacer bar used between the two panes.
