Superior Quality - Our garage door windows inserts feature frames made of thickened vinyl material, paired with acrylic glass panels that offer higher light transmission than regular glass, yet are lighter and more durable. Additionally, they boast better weather resistance and chemical stability, resisting aging and yellowing. Replacement/DIY - NeatiEase garage windows measure 14"x21"x2", fitting most standard garage door window sizes. Please confirm the size of your existing window before purchase to ensure a perfect fit. If your garage door doesn't have a window, you can also DIY. This way, we cater to homeowners' needs in various aspects, from aesthetics and energy efficiency to durability and safety.
