Choosing an Andersen casement window involves more than deciding that you want a side-hinged window that cranks outward. Andersen offers casements across several product series, and the differences between those products can affect the window’s materials, appearance, customization, performance options, and overall project cost.
For homeowners in Virginia Beach and throughout Hampton Roads, the main Andersen casement choices are 100 Series, 400 Series, A-Series, and E-Series. Andersen also offers an E-Series French casement, which uses two side-hinged sashes without a fixed center meeting stile. Each option serves a somewhat different homeowner priority, from straightforward composite construction to highly customized wood-and-aluminum designs.
This guide focuses on those series and product differences. If you’re still deciding whether casement operation is right for your home, start with our Guide to Andersen Casement Windows. For a broader look at the full Andersen lineup, visit our Ultimate Guide to Andersen Windows in Hampton Roads.
Andersen Casement Windows at a Glance
| Product | Primary Construction | Customization Level | Key Reason to Compare |
|---|---|---|---|
| 100 Series Casement | Fibrex® composite interior and exterior | Moderate | Low-maintenance composite construction and value |
| 400 Series Casement | Wood interior / vinyl exterior | Broad | Best-selling Andersen casement with versatile design options |
| A-Series Casement | Wood interior / fiberglass & Fibrex® composite exterior | High | Andersen’s best-performing casement and architectural detailing |
| E-Series Casement | Wood interior / aluminum exterior | Very high | Broadest color and design freedom |
| E-Series French Casement | Wood interior / aluminum exterior | Very high | Paired sashes with no fixed center meeting stile |
The best series is not automatically the highest or most customizable one. The right choice depends on which materials, finishes, sizes, performance characteristics, and design features actually matter for your project.
100 Series Casement Windows
The 100 Series is Andersen’s Fibrex® composite casement option. Fibrex material is used on both the interior and exterior, giving homeowners a different alternative to traditional vinyl or wood-interior construction.
Andersen positions the 100 Series as a value-oriented, virtually maintenance-free option. Casements are available as individual units as well as twin and triple combinations, and Andersen also offers the product as a replacement insert window. Low-E glass options are available, and the line includes several interior and exterior color choices, including darker finishes.
For a homeowner who likes casement operation but does not need a natural wood interior or extensive architectural customization, the 100 Series can be a practical place to begin.
- Consider 100 Series when: you prioritize composite construction, lower maintenance, straightforward design choices, and value.
- Compare another series when: you want a natural wood interior, a much broader color palette, more architectural detailing, or higher levels of customization.
400 Series Casement Windows
The 400 Series is Andersen’s best-selling casement window. It uses a natural wood interior with a low-maintenance vinyl exterior designed to protect the window from weather while preserving the appearance of wood inside the home.
Compared with the 100 Series, the 400 Series expands the design possibilities. Andersen currently offers seven exterior colors and four interior choices, including unfinished natural pine, along with multiple hardware styles, up to nine hardware finish options, and both standard and custom grille patterns. Custom sizing is also available in small increments.
Andersen offers both contemporary and traditional interior profile options on select 400 Series products. That flexibility helps the same basic casement design work with a broader range of home styles.
- Consider 400 Series when: you want a wood interior, broad design flexibility, and Andersen’s most popular casement platform.
- Compare another series when: you prefer Fibrex composite throughout, need the architectural/performance focus of A-Series, or want the much larger color and finish palette available with E-Series.
A-Series Casement Windows
A-Series is part of Andersen’s Architectural Collection and is identified by Andersen as its best-performing casement window. The product uses a wood interior protected on the exterior by fiberglass and Fibrex composite materials.
The series is designed around both performance and architectural authenticity. Homeowners can choose from a broad selection of factory-finished wood interiors and exterior colors, while custom grille patterns and other design details can help coordinate the windows with a specific architectural style.
A-Series also offers triple-pane glass options. For Hampton Roads projects where enhanced performance specifications, architectural proportions, or coastal-related product requirements are important, A-Series deserves a close comparison using the actual performance data for the proposed window configuration.
- Consider A-Series when: performance, architectural detailing, wood interiors, larger configurations, and premium design choices are high priorities.
- Compare another series when: your project does not require the additional architectural or performance features and a simpler product already meets your needs.
E-Series Casement Windows
E-Series is Andersen’s most customizable standard casement option. It combines a wood interior with a virtually maintenance-free aluminum exterior, allowing Andersen to offer a substantially broader range of exterior colors and interior design choices.
Andersen currently lists 50 exterior colors and 14 interior colors for the E-Series casement, along with multiple wood species, stains, hardware finishes, grille patterns, and custom sizing. This makes E-Series particularly relevant when the window needs to coordinate with a specific exterior palette, interior millwork, cabinetry, flooring, or architectural design.
The series also offers advanced hardware possibilities. Andersen notes that E-Series casements can be configured with PowerAssist™ power operation, allowing compatible windows to be opened electronically rather than only by hand.
- Consider E-Series when: maximum design freedom, color matching, wood species, stains, custom configurations, and premium architectural flexibility matter most.
- Compare another series when: you do not need extensive customization and would rather keep product selection and project cost more streamlined.
E-Series French Casement Windows
The E-Series French casement is a specialized variation that changes what happens at the center of a paired opening. Instead of two casement windows meeting against a fixed center post, the paired sashes are designed without a fixed center meeting stile.
When both sashes are open, the result is a broad, unobstructed opening. That can make a French casement appealing when homeowners want expansive ventilation, clearer sightlines through a paired opening, or a more distinctive traditional architectural feature.
Because the French casement is part of E-Series, it also benefits from the line’s wood interiors, aluminum exterior protection, broad color palette, and extensive customization.
- Consider E-Series French casement when: you want paired casement operation without a fixed center stile and the design flexibility of E-Series.
- Compare standard casements when: a single operating sash or conventional joined casement configuration better fits the opening, budget, or design.
How Do Andersen Casement Series Compare by Material?
Material is one of the clearest ways to distinguish Andersen’s casement products.
- 100 Series: Fibrex composite on both the interior and exterior. This is the only primary Andersen casement in this comparison without a wood interior.
- 400 Series: Natural wood interior protected by a vinyl exterior.
- A-Series: Wood interior protected by fiberglass and Fibrex composite materials on the exterior.
- E-Series: Wood interior protected by an aluminum exterior.
There is no universally superior construction for every homeowner. A composite interior may appeal to someone focused on maintenance, while a wood interior may be more important in rooms where the window is a visible part of the interior architecture.
Which Andersen Casement Has the Most Design Options?
E-Series is the strongest starting point when customization is the primary goal. Its aluminum exterior supports Andersen’s broadest color offering, while the wood interior can be customized with different species, stains, and finishes.
A-Series also provides substantial design flexibility, particularly for homeowners interested in architectural authenticity and factory-finished wood interiors. The 400 Series provides a useful middle ground with several exterior and interior choices, hardware styles, and grille patterns. The 100 Series keeps the selection more focused.
The practical question is how much customization your project actually needs. Paying for a broader palette or specialty interior finish only makes sense if those options contribute to the finished design of the home.
Which Andersen Casement Is Best for Energy Efficiency?
Casement windows as a style can provide strong energy performance because the operating sash closes tightly against the frame. However, the series name alone does not determine the final efficiency of the window.
Andersen identifies A-Series as its best-performing casement and offers triple-pane glass through both A-Series and E-Series. Low-E glass options are available throughout the broader casement lineup. Actual performance depends on the specific frame, glass package, size, configuration, installation, and exposure.
For Hampton Roads homeowners, compare the performance ratings for the exact product being proposed rather than assuming that every casement within a series performs identically.
Which Andersen Casement Is Best for Hampton Roads Homes?
There is no single Andersen casement series that is automatically best for every Hampton Roads home. The region includes everything from inland neighborhoods to homes with greater coastal exposure, and project priorities vary just as widely.
- For value and lower-maintenance composite construction: start by comparing 100 Series.
- For a versatile wood-interior casement: 400 Series is an important benchmark and Andersen’s best-selling casement.
- For performance and architectural detail: compare A-Series and confirm the specifications appropriate for the home’s exposure and project requirements.
- For maximum design customization: E-Series provides the broadest palette of exterior colors, interior woods, finishes, and configurations.
Heat, humidity, wind-driven rain, coastal air, and seasonal storms make proper product selection and installation important, but location alone should not be used to automatically push every homeowner into the same Andersen series.
Standard Casement vs. French Casement
| Feature | Standard Andersen Casement | E-Series French Casement |
|---|---|---|
| Operation | One side-hinged sash per window | Two side-hinged sashes in one paired opening |
| Center of paired opening | Joined units can have framing between windows | No fixed center meeting stile |
| Open view | One operating sash at a time | Wide clear opening when both sashes are open |
| Series availability | 100, 400, A-Series and E-Series | E-Series |
| Best fit | Most conventional casement applications | Specialized paired openings and architectural designs |
What About Andersen Aluminum Casement Windows?
Andersen also markets an Andersen Aluminum casement line, but it is not a primary option for Better View’s Hampton Roads market. Andersen states that these products are available through select dealers in the Southwest region of the United States.
For Virginia Beach and Hampton Roads homeowners, the relevant Andersen casement comparison is therefore 100 Series, 400 Series, A-Series, E-Series, and E-Series French casement.
How Much Do Andersen Casement Windows Cost?
Andersen does not publish one universal installed price for each casement series because the final cost depends on the complete window and the installation. Series, dimensions, glass, hardware, grilles, interior and exterior finishes, custom sizing, installation conditions, trim work, and the number of windows being replaced can all affect pricing.
At a broad level, 100 Series is positioned as a value-oriented composite option, while 400 Series adds wood-interior construction and broader choices. A-Series and E-Series move further into premium performance, architectural detailing, and customization. The E-Series French casement adds another specialized configuration.
The most useful comparison is therefore not simply the price of one series versus another. Better View recommends comparing products configured to solve the same opening, design, and performance requirements so you can see what additional value each series provides.
What We Recommend Comparing in the Showroom
Casement windows are especially useful to compare in person because operation and hardware are a major part of the ownership experience.
- Crank operation: Open and close each window to compare how the hardware feels and how far the sash projects outdoors.
- Frame and sash profiles: Compare visible glass area and how the frame proportions change from one series to another.
- Interior material: Look at Fibrex composite beside the wood interiors available in 400 Series, A-Series, and E-Series.
- Exterior material and color: Compare composite, vinyl, fiberglass/composite, and aluminum protection along with the available color palettes.
- Hardware: Review handle styles, finishes, folding hardware, and specialized E-Series options.
- Screens: Consider visibility, removal, and how the screen fits into the interior appearance of the window.
- Customization versus cost: Identify which upgrades you would actually notice or use before moving into a more customizable series.
If you’re considering casement windows as part of a larger projecting window configuration, you may also want to compare Andersen bay and bow window options. Bay and bow assemblies can incorporate casement windows while adding different projection angles, ventilation choices, views, and design considerations.
