5665 Series Single Hung Windows

The WindStrong Series 5665 is MGM's premier Architectural New Construction PVC Vinyl Single Hung Window. It looks the same as the 5610 Single Hung Window, but has been upgraded with engineered structural improvements that allows it to hold up to high wind loads. The 5665 has been tested at MGM's test facility and retested at a third party testing facility. The 5665 should be a good choice for customers who would like extra strength and security without the need for laminated impact rated glass.
