What are Andersen 400 Series products made of?
400 Series products are primarily made from wood with a Perma-Shield® exterior cladding. The wood provides natural strength, insulation, and interior beauty while the Perma-Shield cladding makes them low-maintenance and weather resistant. Perma-Shield cladding is a proprietary, high-grade vinyl that we vacuum form or extrude around the wood for a superior seal.
Like all of our products, 400 Series windows and doors are fine-tuned with the right materials in the right places, which also includes fiberglass and our proprietary Fibrex® composite material.
How much do Andersen 400 Series windows and doors cost?
In terms of cost, the 400 Series product line sits in the middle of our portfolio. As with all window and door pricing, exact cost varies by the product options you choose (size, type of door, configurations), your location, and your project type.

Are Andersen 400 Series products worth it?
