The Product Lines, Side by Side
Andersen sells five main series. Each targets a different budget and use case. The 400 Series is their best-seller; in a 2024 brand survey of U.S. contractors, it was the series contractors said they’d choose for their own homes.
| Series | Frame Material | Installed Cost Range | Best For |
|---|---|---|---|
| 100 Series | Fibrex® composite | $400 – $1,500 | Low-maintenance, budget-conscious buyers |
| 200 Series | Wood interior / vinyl exterior | $1,200 – $1,500 | Classic wood look, value pricing |
| 400 Series | Wood interior / aluminum-clad exterior | $500 – $3,000 | Maximum customization, proven durability |
| A-Series | Fibrex® composite exterior | $1,100 – $4,000 | High-performance, architectural projects |
| E-Series | Aluminum-clad wood | $1,000 – $3,800 | Extensive customization, designer colors |
Cost ranges reflect installed pricing and vary by window size, style, glass package, and labor. A standard double-hung and a large custom casement are both “400 Series” on paper, they just land in very different spots on that range.
What Fibrex Actually Is
Andersen’s Fibrex material shows up across multiple product lines and gets mentioned a lot in their marketing. It’s worth understanding what it is before taking the claims at face value.
Fibrex is a composite made from approximately 40% pre-consumer reclaimed wood fiber and thermoplastic polymer. Andersen holds the patent. It’s used in the 100 Series and A-Series, and it’s the exclusive frame material for Renewal by Andersen (the company’s full-service replacement brand).
Compared to standard vinyl, Fibrex has a lower coefficient of thermal expansion, which means less warping and bowing during temperature swings. Andersen and Renewal by Andersen are also the only window companies to hold SCS Indoor Advantage Gold certification for indoor air quality.
The 100 Series warranty covers frame members for 10 years, the same duration as the A-Series. Make of that what you will when evaluating marketing claims about durability.
Glass Options and Energy Performance
All 100 Series windows come standard with Low-E glass. The upgrade path leads to SmartSun Low-E glass, which blocks 95% of UV rays.
Andersen’s High-Performance Low-E4 glass, available across several series, is rated 45% more energy efficient in winter and 56% more efficient in summer compared to ordinary dual-pane glass, and can reduce energy bills by up to 25%, per Andersen’s published data.
Here are the published U-factor ratings by series:
- 100 Series: 0.34 U-factor
- 200 Series: 0.36 U-factor
- 400 Series: 0.33 U-factor
- A-Series: 0.32 U-factor
For a climate that swings between cold winters and hot, humid summers, the glass package you choose matters as much as the frame series.
The 400 Series: Why It Outsells Everything Else
The 400 Series has been in production for over 50 years. It has gone through comprehensive accelerated weather testing and comes with a 20-year warranty on standard glass and 10 years on non-glass components.
The wood interior gives it a warmer look than composite or vinyl frames, and the aluminum-clad exterior handles weather without requiring paint.
Installed costs for a standard double-hung run $1,450 to $1,850 in most markets. On larger projects, the price gap between the 100 Series and 400 Series becomes significant, the series you choose early on will determine the total budget more than anything else.
What Buyers in This Market Are Usually Deciding Between
Most homeowners shopping Andersen are weighing it against Pella and Marvin. All three sit in the premium tier. The practical differences come down to:
- Customization depth: Andersen’s E-Series offers 50 standard colors and exotic wood interiors.
- Material preference: Wood interior buyers often land on 400 Series. Buyers wanting low-maintenance exteriors without the wood aesthetic tend toward 100 Series or vinyl alternatives.
- Price sensitivity: The 100 Series closes the gap with premium vinyl brands at a lower entry point than the 400 Series.
If you’re working with an older home and want the wood interior but need the frame to hold up for decades without significant maintenance, the 400 Series is the most field-tested option in the Andersen lineup.
For a straightforward, budget-conscious replacement, the 100 Series competes directly with vinyl window options at a similar price point while offering Andersen’s material warranty.
