Affinity Windows prices range from $45 to $65 per square foot. Affinity offers three window series and their low and mid range models don't get much attention. Their premium option, the Energex Elite, is widely regarded as a very good vinyl window by contractors and installers.
Affinity windows has gone out of business and is no longer manufacturing and producing vinyl windows. Not good news for anyone who purchased these windows due to the lack of relief if issues should arise with your windows.
