Good replacement window manufacturers include Andersen, Simonton and Marvin, according to a Consumer Reports guide published in September 2014. Andersen rated highly for wood double-hung, wood casement and vinyl casement replacement windows. Simonton scored well for its vinyl double-hung models, while Marvin's Ultrex Fiberglass line represents a good fiberglass window.
Andersen manufactures awning, casement, hung, gliding and specialty windows for installation in homes. Marvin touts its Ultrex Fiberglass as a window with less expansion and more strength compared to vinyl windows, and Simonton allows customers to browser 13 different types of windows for their homes as of 2015.
Consumer Reports suggests that homeowners shop around for the best prices on replacement windows since prices vary among retailers and dealers. Online design tools can help consumers pick the correct windows by size, shape, material and ratings for all types of windows.
