400 Series windows and doors

A long time, even in tough climates — it’s what they’re known for! The 400 Series product line includes products that have been validated through 50+ years of real-world use and experience. They have gone through comprehensive accelerated weather testing to confirm performance over time and come with one of the industry’s best limited warranties with 20 years on standard glass and 10 years on non-glass.* They are the window contractor’s trust for their own homes.**

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.

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. Visit our pricing page for more information, or request a quote so a dealer can provide you with an accurate estimate.

The 400 Series is our most popular and longest-standing product line, with a balance of design options, price, and performance to fit a wide variety of projects. Built on decades of engineering and innovation, they’re the windows contractors trust the most.* Want a detailed comparison of our product lines? Compare windows and compare doors.
