Andersen is one of the best-known names in the window industry, but reputation alone doesn’t make a window right for your home. If you’re comparing Andersen replacement windows to other window brands, the better question is whether the material, style, glass package, and price make sense for your particular project.
For many Denver homeowners, the answer is yes. Andersen offers options ranging from low-maintenance Fibrex® composite windows to premium wood windows with extensive design flexibility. The company also offers a broad selection of window styles and energy-efficient glass packages. Still, there is no single Andersen series that is best for every home or budget.
This guide looks at where Andersen windows stand out, what you should consider before buying, and how to choose a product that fits your Denver home.
Why Andersen Has Such a Strong Reputation
Andersen has been making windows and doors for more than a century. That history matters, but homeowners are usually more interested in what Andersen offers today: dependable materials, plenty of design choices, and product lines for different homes and budgets.
One of Andersen’s biggest strengths is variety. Its window lines include composite, wood-and-vinyl, wood-and-composite, and wood-and-aluminum construction. That gives homeowners room to prioritize low-maintenance, authentic wood interiors, architectural detail, or a specific exterior finish.
Depending on the series and configuration, Andersen windows are available in popular styles such as casement, awning, double-hung, single-hung, gliding, picture, bay, bow, and specialty shapes. Homeowners can also compare colors, grille patterns, hardware, glass packages, and insect screens.
That flexibility is valuable, but it can also make it difficult to know where to start. DMD Window & Door can help you compare your options and choose the right products for your Andersen window installation in Denver.
What Are Andersen Windows Made From?
One reason homeowners consider Andersen windows is the variety of materials available across the brand’s product lines. Some are made with low-maintenance Fibrex® composite, while others pair real wood interiors with protective exterior materials. Understanding those differences will help you find the right balance of appearance, upkeep, performance, and price.
Fibrex® Composite Windows
Andersen’s 100 Series is made with Fibrex®, the company’s composite material. Fibrex combines wood fiber with a thermoplastic polymer to create a strong, low-maintenance frame. Andersen states that the material is twice as strong as vinyl and resists fading, flaking, blistering, peeling, rot, and decay.
For Denver homeowners, it’s easy to understand the appeal. Fibrex offers the easy upkeep many people want from vinyl, along with a rigid frame and a clean, contemporary appearance. It’s a good option for homeowners replacing several windows and looking for a balance of durability, style, and cost.
Wood Windows With Protected Exteriors
Andersen’s 200 and 400 Series pair real wood interiors with low-maintenance vinyl exteriors. The A-Series uses wood interiors with Fibrex and fiberglass exterior components, while the E-Series uses wood interiors with aluminum exteriors.
These lines appeal to homeowners who want the warmth of real wood inside the home without leaving the exterior wood fully exposed. Wood interiors can also be a better visual match for traditional Denver homes, existing millwork, or rooms where the windows are an important design feature.
The tradeoff is price and upkeep. Wood windows generally cost more than composite options, and painted or stained interiors may need occasional cleaning and finish touch-ups.

Andersen’s product lines are designed for different homes, budgets, and priorities. Our detailed Andersen 100 Series vs. 200 Series comparison can help if you are deciding between two of the brand’s most popular replacement options. Keep in mind that available sizes, styles, glass packages, colors, and performance ratings vary by series and configuration.
Are Andersen Windows Energy Efficient?
Many Andersen windows are available in ENERGY STAR® certified configurations, but the brand or series name does not tell you everything about energy performance. Window style, size, frame construction, glass package, and installation all affect the result.
Andersen offers Low-E glass options designed to manage heat transfer and reduce ultraviolet light entering the home. Some products are also available with different glass packages for sun exposure, climate, and performance goals.
Denver’s sunny days and wide seasonal temperature swings make glass selection worth discussing room by room. A large west-facing window may have different needs than a smaller opening protected by a porch. At DMD Window & Door, we’ll look at those differences instead of recommending the same glass package throughout your house without explanation.
What Do Andersen Replacement Windows Cost?
There isn’t one standard price for Andersen replacement windows. The series, window style, dimensions, glass, color, hardware, installation method, trim work, and condition of the existing opening all affect the final price.
A standard-size 100 Series window will not be priced like a custom E-Series unit, and replacing an insert window in a sound opening is different from rebuilding an opening with hidden water damage. This is why online price ranges are often too broad to help with an actual budget.
When comparing estimates, make sure your proposals clearly state:
- The Andersen series and window style
- The frame, interior, and exterior materials
- The exact glass package
- Interior and exterior colors or finishes
- Grilles, hardware, and screens
- Removal, disposal, insulation, sealing, trim, and finish work
- Product and workmanship warranty coverage
Comparing the complete scope helps prevent a lower quote from looking like a better value simply because important work or options were left out.
Installation Is Part of the Decision
The window itself is only part of the finished project. Measurements, opening preparation, flashing, insulation, sealing, and trim work all affect how the window looks, operates, and handles weather.

So, Are Andersen Windows Worth It?
For homeowners who value established products, multiple material choices, energy-efficient glass options, and design flexibility, Andersen windows are often worth considering. The 100 Series offers a practical composite option, while the wood product lines give homeowners more choices for traditional architecture and custom design.
Andersen is not necessarily the right choice for every home. The best value comes from choosing the right series and glass package for your home—not simply choosing Andersen because it is a familiar name.
If you’re considering Andersen windows, start by deciding what matters most: lower maintenance, a real wood interior, energy performance, architectural detail, or budget. From there, an experienced installer can narrow the options to products that genuinely fit the project.
Frequently Asked Questions About Andersen Windows
Which Andersen series is best for replacement windows?
There is no single best series. The 100 Series is popular for low maintenance and value. The 200 and 400 Series add real wood interiors, while the A-Series and E-Series offer more premium design options. The right choice depends on the home, desired finish, window style, and budget.
Are Andersen Windows and Renewal by Andersen the same?
They are related, but they are not the same purchase and installation channel. Andersen manufactures several product series sold through dealers and certified contractors. Renewal by Andersen is Andersen Corporation’s full-service replacement division with its own product and installation process. DMD is an Andersen Certified Contractor and installs Andersen window products.
What is Fibrex® material?
Fibrex® is Andersen’s proprietary composite material made from wood fiber and thermoplastic polymer. It offers the low-maintenance benefits many homeowners want while providing greater strength and rigidity than standard vinyl. Andersen uses Fibrex most prominently in its 100 Series windows.
Can Andersen replacement windows fit existing openings?
In many cases, yes. Some Andersen windows are available as replacement inserts that fit within a sound existing frame. If the frame has rot, water damage, or other problems, a full-frame replacement may be the better option. DMD will inspect and measure each opening before recommending an installation method.
How do I know which Andersen glass package is right for my home?
The right glass package depends on the direction each window faces, the amount of shade it receives, and what you want to improve. For example, a west-facing room that gets intense afternoon sun may need a different glass option than a shaded north-facing room. DMD can help you compare the ratings and choose appropriate glass for each part of your home.
