What is the difference between the Andersen 100, 400, and E-Series windows?

The 100 Series uses Fibrex composite, a blend of wood fiber and thermoplastic polymer, and comes in five exterior colors. It is a durable, low-maintenance option that outperforms standard vinyl in heat. The 400 Series has a wood core, offers more customization choices, and includes Stormwatch protection for weather-exposed locations. The E-Series is aluminum-clad wood with over 50 standard exterior colors, making it the most flexible option for architects and custom projects. The E-Series is generally not available through big-box retail and requires an authorized distributor to source.

Does Western Window & Door carry the full Andersen catalog, or just select series?

As an authorized Andersen distributor, Western Window & Door has access to the complete Andersen lineup, including series not stocked in general retail stores. This includes the 100, 200, 400, A-Series, and E-Series windows, as well as Andersen exterior door systems. Ordering through an authorized channel also ensures that the manufacturer warranty on your product remains valid and fully transferable according to Andersen's terms.

Can Andersen windows meet California Title 24 energy code requirements?

Multiple Andersen series are available with SunCoat and SunCoatMAX Low-E glass packages, which are designed to meet California's Title 24 energy code requirements. The right glass package depends on your specific climate zone. Vacaville and Fairfield fall within the Central Valley heat corridor, where SunCoatMAX is often the appropriate choice for afternoon sun exposure. Western Window & Door can help identify the correct glass specification for your project based on your location and the series you are considering.

What exterior color options are available for Andersen windows?

Andersen uses a Sherwin-Williams color match system for exterior finishes. Standard exterior color codes include White, Sandtone, Terratone, Dark Bronze, Cocoa Bean, and Prairie Grass. Interior stain options include Honey, Russet, Espresso, Mocha, and Cinnamon. The E-Series offers more than 50 standard exterior colors, providing the broadest range of finish options across the lineup. Availability by series can be confirmed at the Vacaville showroom.

Does Western Window & Door install Andersen windows and doors?

No. Western Window & Door is a supply-only business and does not provide installation, repair, or maintenance services. The company sources and supplies product directly to homeowners and contractors, who then manage labor independently. The owner has a background in installation from running an installation business from 2004 to 2016, which informs the product guidance provided, but no installation work is performed or arranged by the business.

Is the Andersen E-Series available through a big-box retailer, or do I need an authorized dealer?

The Andersen E-Series is generally not available through big-box retail stores. Because it offers more than 50 standard exterior colors and a wide range of custom configurations, it requires an authorized distributor to order and source correctly. Purchasing through an authorized dealer also protects the warranty coverage and ensures you are working with someone who has access to the full specification range rather than a limited in-store selection.

What Andersen series works best for older California homes with non-standard openings?

Older California homes often have non-standard rough opening sizes, which can make standard off-the-shelf sizing a poor fit. The 400 Series and E-Series both offer extensive sizing and configuration options that can accommodate unusual openings more reliably than entry-level series. The owner's background in installation means the product guidance at Western Window & Door takes into account practical fit considerations, not just catalog specs. Bringing measurements and photos of the existing opening to the showroom helps narrow down the right series for the project.

Andersen | Western Window & Door, Inc.

Western Window & Door, Inc. is an authorized Andersen window supplier serving Vacaville, Fairfield, Napa, and the surrounding Northern California region. Whether you are a homeowner replacing aging windows or a contractor sourcing Andersen door products for a new build, we carry the full series lineup, from the entry-level 100 Series to the architecturally flexible E-Series. Our supply-only model means you get direct access to manufacturer-authorized product with no installation markup bundled in. We are a product supplier only and do not provide installation, repair, or maintenance services.

Andersen offers one of the most comprehensive window series available to Northern California homeowners and builders, and Western Window & Door stocks and orders across the entire catalog. The 100 Series uses Fibrex composite, a proprietary blend of wood fiber and thermoplastic polymer, available in five exterior colors and built to outperform standard vinyl in temperature stability. The 200 Series pairs a Perma-Shield exterior with a genuine wood interior, making it a practical entry point for buyers who want real wood aesthetics without the full cost of a premium series. The 400 Series is Andersen's best-selling line, featuring a wood core with extensive customization options and Stormwatch protection for high-wind and weather-exposed installations. For projects where energy performance is the top priority, the A-Series combines Fibrex and fiberglass construction to deliver maximum thermal efficiency. At the top of the lineup, the E-Series offers aluminum-clad wood with more than 50 standard exterior colors, giving architects and designers near-unlimited flexibility for contemporary or historically sensitive projects. This series is not typically available through big-box retail, making authorized dealer access essential for sourcing it.

Beyond windows, Andersen produces a range of exterior door systems that pair directly with their window lines for a consistent architectural look. Sliding patio doors, hinged French doors, and multi-panel configurations are all available through our Vacaville showroom. For projects requiring moving glass wall systems, the AX Series provides a high-performance option suited to open-plan living spaces and indoor-outdoor transitions common in Northern California home designs. All Andersen door products we carry are sourced through authorized distributor channels, which means full warranty coverage and access to the complete specification range, not just what a general lumberyard happens to stock. Our team can help match door profiles to window series so the sightlines, finishes, and hardware coordinate across the entire project.

Andersen replacement windows are a frequent choice for Northern California homeowners dealing with drafts, failed seals, or rising energy costs. The Fibrex-based series in particular holds up well against the temperature swings common in the Central Valley, where summer heat and cooler evenings put repeated stress on frame materials. SunCoat and SunCoatMAX Low-E glass options are available across multiple series to help meet California Title 24 energy code requirements, which apply to most replacement projects in the state. Because our owner has a background in installation from over a decade of running an installation business, the product guidance we provide goes beyond what a typical showroom offers. We can speak to how specific series perform in the field, which frame configurations work in older California homes, and which glass packages are appropriate for your climate zone, without steering you toward a product based on margin.

Purchasing Andersen windows and doors through an authorized distributor like Western Window & Door gives you access to the complete product catalog, including series and configurations that are simply not available through general retail channels. It also ensures that the warranty attached to your product is valid and transferable under Andersen's terms. Big-box retailers typically carry a limited subset of the Andersen lineup, and their staff are generalists rather than specialists in window and door specifications. At our Vacaville location, you are working with a supplier that carries Milgard 101 Certification, has been in business since 1982, and operates a 900 sq. ft. professional showroom where you can see product series side by side before making a decision. For contractors, our supply-only model means no installation markup obscuring the product cost, and ordering goes through a direct channel with the logistical advantages of a regional supplier. Andersen's Sherwin-Williams color match system for exterior and interior finishes is also available through our showroom, covering exterior codes including White, Sandtone, Terratone, Dark Bronze, Cocoa Bean, and Prairie Grass, along with interior stain options such as Honey, Russet, Espresso, Mocha, and Cinnamon.
