Marvin's Ultrex® fiberglass finish is verified to the American Architectural Manufacturers Association (AAMA) 624 specification. Achieving AAMA 624 verification means that our Ultrex finish has passed rigorous tests that simulate the harsh conditions a finish can encounter throughout the life of the window or door. Average sunlight exposure per 10 years.
We use the same tough acrylic finish on our four interior color options that we use on our exterior. You can also choose our stainable EverWood® finish for the look of wood - without the maintenance.

Our Marvin Replacement experts will walk you through our energy-efficient glass options to find the right selection for your home and specific climate needs.
Low E-1
Primarily used in colder climates, Low E1 allows more heat in to warm a room while blocking heat loss.

Low E2 offers year-round performance in moderate climates. It will help retain heat in your home during the winter and keep heat out during the summer.
Low E3 rejects solar heat while letting light in, resulting in increased performance in climates with intense sun exposure.
Low E-3/ERS
Low E3/ERS provides maximum efficiency year-round in all conditions.
Decorative glass
Decorative glass options are ideal for spaces like bathrooms to balance natural light and privacy.
Specialty glass
Specialty glass options may be used if you are looking to minimize outdoor noise, if your window is located close to the ground, or you have security concerns.
