Why choose the Andersen 100 Series?

Andersen 100 Series windows and doors offer superior strength and performance to vinyl,  engineered with Fibrex® composite material. This modern, budget-friendly collection is an excellent choice for replacement and remodel projects in addition to new builds. And with superior resistance to warping, the 100 Series brings peace of mind that your windows will perform well in any climate.



Crafted with durable composite materials, the windows and doors featured in the Andersen 100 Series are smart alternatives to vinyl. Let in fresh air with 100 Series casement windows, awning windows, single-hung windows, and gliding windows — or amplify natural light with a 100 Series picture window or specialty window customized for your home.



Andersen 100 Series windows and doors are made from Andersen’s Fibrex® composite material. Twice as strong as vinyl, this innovative, low-maintenance material is energy efficient and designed to retain its stability in all climates. 100 Series products can withstand temperatures up to 150°F — even in dark colors — meaning they won’t warp due to sun exposure.


Design Options

100 Series windows and doors bring a sleek, contemporary style to your home. Featuring a beautiful matte finish, the window frame isn’t shiny like vinyl and it’s virtually maintenance-free. 100 Series windows and patio doors are available in 5 exterior color options and 4 interior color options — each providing a richly colored, scratch-resistant finish you’ll enjoy for years to come. And with many grille patterns to choose from, the 100 Series integrates beautifully with your home’s aesthetic.


Energy Efficiency

Andersen windows are engineered for durability and weather resistance that protect your home from the elements. Homeowners can choose from various high-performance and Low-E glass options to achieve the best energy efficiency in their region. The weather-resistant construction of 100 Series windows successfully seals out drafts, wind, and water.
