It’s designed for homeowners who want top-tier performance and style. These windows combine strength, beauty, and energy efficiency in one package. ### Key Features of the A Series - **Material:** The A Series uses Fibrex® composite material. This is a blend of wood fibers and vinyl, making it strong and durable. - **Durability:** Fibrex resists warping, rotting, and cracking better than wood or vinyl alone. - **Design Options:** You get a wide range of colors, finishes, and grille patterns. The interior can be wood or painted Fibrex. - **Energy Efficiency:** A Series windows come with high-performance glass options, including Low-E coatings and triple-pane glass. - **Customization:** You can choose from many styles like casement, double-hung, and picture windows. ### Why Choose the A Series? The A Series is perfect if you want a window that looks great and lasts for decades. It’s especially good for homes in harsh climates because the Fibrex material handles moisture and temperature changes well. Plus, the energy-efficient glass helps reduce heating and cooling costs. ## Exploring Andersen Windows 400 Series The 400 Series is Andersen’s most popular window line. It balances quality and affordability, making it a favorite for many homeowners. ### Key Features of the 400 Series - **Material:** The 400 Series frames are made from Fibrex composite, just like the A Series. - **Durability:** These windows are also resistant to rot and warping. - **Design Options:** The 400 Series offers fewer color and finish choices compared to the A Series but still provides classic styles. - **Energy Efficiency:** It features Low-E glass and double-pane options, which meet most energy codes. - **Styles Available:** Includes double-hung, casement, awning, and gliding windows. ### Why Choose the 400 Series?
