The 400 Series is Andersen's most popular line and the benchmark for wood replacement windows. Natural wood interiors deliver warmth, strength, and insulation, while the Perma-Shield® exterior cladding makes them remarkably low-maintenance and weather-resistant — the best overall blend of performance, style, and proven durability.
Emerald City Energy is an authorized Andersen installer serving the Puget Sound since 1997 — here's what sets the Andersen 400 Series apart.
Beautiful natural wood inside, ready to stain or paint, with the strength and insulation only real wood provides.
A rugged exterior cladding shrugs off rain, sun, and seasonal swings without painting or scraping.
The widest range of sizes, styles, exterior colors, grilles, and hardware of Andersen's clad-wood lines.
Decades of field-proven durability plus High-Performance™ Low-E4® glass options for real energy savings.
A range of operating styles to fit every room, view, and architectural look — all installed by Emerald City Energy.

It offers the best overall balance Andersen makes: the warmth and strength of a real wood interior, a low-maintenance Perma-Shield® exterior, and the widest selection of sizes, styles, and colors — backed by decades of proven performance.
Perma-Shield is Andersen's protective exterior covering over the wood frame. It resists weather, won't rot, and never needs painting, so the window keeps its looks with minimal upkeep.
Both have wood interiors. The 400 Series uses a more durable Perma-Shield exterior and offers far more sizes, shapes, colors, and grille options, while the 200 Series is a streamlined, value-priced line with a vinyl exterior.
Both tilt in for easy cleaning. The Woodwright® has a more traditional, true wood look with a putty-style glazing profile, while the Tilt-Wash is a versatile, contemporary clad-wood option.
