The Andersen® 400 Series windows provide a classic blend of engineering and craftsmanship, featuring extensive sizes, shapes, styles and colors. Andersen designs each product to meet demanding standards. And each is available with a full array of options and accessories to give your project a customized look.

We craft our frames in virgin vinyl. They are heavy duty and feature a distortion-resistant multi-chambered profile for the ultimate in stability, energy efficiency, low maintenance and lasting beauty.

The vinyl itself is practically maintenance-free. The frames are guaranteed not to rust, peel, chip, corrode or need painting. As the color is fully integrated throughout the frame, fading is a thing of the past.

For beauty you can see and feel, our frames and sashes are miter-cut and fusion welded. Only the finest heavy-duty hardware is used. These techniques combine to assure our customers a beautiful, long lived product with clearly superior performance.
