This is also something important to homeowners in the Northeast when you think about ice building up on the window in the winter. CR measures how well the window resists water build-up.
Condensation Resistance is scored on a scale from 0 to 100. The higher the condensation resistance factor, the less build-up of moisture the window allows.
Obviously the higher the condensation resistance of a window the better and more it may cost. HIGHER IS BETTER
