Andersen® 400 Series casement windows start with a design that is extremely energy efficient. Add to that a solid-wood sash covered inside and out by low-maintenance Perma-Shield® cladding to protect against water damage. Then give them rich, natural pine interiors and it’s easy to see why they have become our best-selling window.
