What is a Hybrid window?
Hybrid windows are unique and far and few between. Certain types of Hybrid windows are manufactured for a "niche" market or to meet certain specifications possibly required by certain Village codes that may be required or a specific aesthetic look select clients may be looking for.
As always don't just get caught up in the fact it may be a hybrid window because if it isn't available in high performance glass options, or is improperly installed, or doesn't come with a better than average warranty then what good is it?
