Choosing new windows isn’t always easy—especially when every option looks good on paper. If you’ve landed on Andersen as your brand of choice (great move), the next question is probably this:

Which Andersen series should I choose: 100, 400, or A-Series?

Let’s walk through the differences in plain language, so you can make the best decision for your home, your style, and your budget.

First Things First: What Do the Series Names Mean?

Think of them like trim levels in a vehicle:

• 100 Series: Durable and modern, built with Andersen’s patented Fibrex® composite inside and out.
• 400 Series: Classic wood interior with a low-maintenance vinyl-clad exterior.
• A-Series: Architectural-grade design with a real wood interior and Fibrex® exterior for the ultimate blend of performance and customization.

Andersen doesn’t make bad windows—it’s just about finding the right fit for you.
