• All colors are formulated right into the vinyl, so the color never fades and your new windows will never need painting or staining.
• Airtight insulating chambers and insulated glass units provide energy-efficient performance throughout every season.
• These windows offer double locks, a feature where the window will not open more than a certain amount, tilt in sashes for easy cleaning, and energy efficiency.
