We replaced 10 windows during a heavy reno on a part of our home and need to do another 18 windows. Are there any suppliers in the USA, China, elsewhere that make a similar/identical product to the Milgard 650 fiberglass series? Started perusing Alibaba. Seeing lots of contractors install China imports in new construction for 1/3 to 1/2 of the cost. Milgard 10 windows were $25k installed or so for new construction install.

Located in SoCal Very High Fire zone, so need fiberglass/title IX, whatever other certifications.

Thanks in advance.
