NEWPRO windows are assigned a U-Factor as low as .17 by the NFRC(2). The EWC states a U-factor of 0.32 is acceptable in the northern climate of the country(1). More importantly, they state windows with a U-factor of 0.22 or less provide superior insulation(1). Remember the lower the U-Factor the more energy efficient the replacement window. That means NEWPRO windows are more resistant to heating or cooling loss providing year round comfort and the opportunity for lower energy bills.

NEWPRO windows are manufactured right here in New England at NEWPRO’s own Massachusetts factory for the New England climate.
