Andersen vs Marvin Windows: Price, Materials & Warranty Compared (2026)

Andersen and Marvin are both Minnesota window makers, and on paper their warranties are nearly identical. The real differences are what the frames are made of and how you buy them. Andersen sells three lines, the 100, 200 and 400 Series, that show up on big-box store shelves with a price on them. Marvin sells only through authorized dealers and publishes no price for any collection.

That makes this an uneven comparison on cost. Andersen's retail lines can be priced, and in our September 2026 census their shelf medians ran $358–$854 per window, unit only. Marvin cannot be priced at all without a quote. Below we show what each brand publishes and leave blank what it does not. To estimate a whole project, use the window replacement cost calculator.

Andersen vs Marvin: What Each Publishes on Price

The Andersen figures are retail shelf prices for the window alone at Home Depot, where every Andersen listing in our census was found. They exclude installation, which our cost model puts at $185 to $200 per opening for a double-hung insert. Marvin's collections are priced by dealer quote only.

A shelf price is not a quote. It is a standard-size unit with no labor, trim or disposal, and the census sees only what big-box stores list online. Andersen's A-Series and E-Series are not in the census and have no published price, the same as Marvin. The fair test is two installed quotes for the same openings: one from an Andersen installer and one from a Marvin dealer. Our installation labor cost guide shows what the labor line should look like.

Line-by-Line: Which Andersen Matches Which Marvin

Each brand sorts its products by tier. Matched on construction, the two lineups pair up like this:

The clearest gap is in the middle tier. Andersen's best seller, the 400 Series, protects its wood with vinyl. Marvin's equivalent, Elevate, protects its wood with fiberglass. Andersen describes Perma-Shield as “a proprietary, high-grade vinyl that we vacuum form or extrude around the wood.” The 200 Series uses the same construction with fewer options. Andersen says the 200 Series focuses on “only the most popular designs and sizes,” while the 400 Series has “more window types, color and hardware options, and larger sizes.”

Fibrex vs Ultrex: The Material Claims

Each brand built its lineup on its own material, and each compares that material with vinyl:

• Andersen Fibrex, used in the 100 Series, is a composite “combining wood fiber and thermoplastic polymer.” Andersen calls it “2x stronger than vinyl” and says it has “a 12x thicker finish than painted vinyl.”
• Marvin Ultrex is Marvin's proprietary fiberglass, used on Essential interiors and exteriors and on Vivid and Elevate exteriors. Marvin's Infinity replacement line states that “Ultrex is 8x stronger than vinyl.”

Each figure is that company's own claim from its own testing, measured against vinyl. No published test puts the two side by side, so “8x” against “2x” does not mean Marvin is four times stronger than Andersen. For the material trade-offs in general, see our vinyl vs fiberglass windows comparison.

Warranty Comparison

On the headline terms the two warranties are close to identical. Both are product warranties, so neither covers the cost of installing the windows.

Read the actual document for your product before you sign. Marvin's current Limited Warranty took effect January 12, 2026, and has its own exclusions for coastal installs, high altitude and EIFS (synthetic stucco) walls. Andersen keeps a separate document for each series on its warranty page.

Full-Service Options: Renewal by Andersen vs Infinity by Marvin

If you would rather not buy windows and hire an installer separately, each brand has a full-service replacement arm:

• Renewal by Andersen was founded in 1995 as “the full-service window and door replacement division of Andersen Corporation.” It builds custom Fibrex windows and installs them through its own installers or contractors it authorizes. See Renewal by Andersen vs Andersen for how it differs from buying Andersen windows yourself.
• Infinity by Marvin sells and installs replacement windows built from Marvin's Ultrex fiberglass and advertises a Limited Lifetime Warranty.

Neither publishes a price. In both cases the price comes from an in-home consultation.

Which Should You Choose?

Choose Andersen if:

• You want a price before you talk to a salesperson. The 100, 200 and 400 Series are listed at big-box stores, so you can check unit prices yourself.
• You want a wood interior on a budget. The 200 Series is a wood window, and Andersen says its price is similar to the 100 Series.
• You have a contractor you trust. A retail line can be bought and handed to the installer you already use.

Choose Marvin if:

• You want fiberglass rather than vinyl on the outside of a wood window. Elevate pairs a wood interior with an Ultrex fiberglass exterior.
• You want an all-fiberglass window. Essential is Ultrex inside and out; Andersen's all-non-wood line is composite, not fiberglass.
• You are working with an architect or a specialty dealer. Marvin sells only through authorized dealers, so the dealer relationship is part of the purchase.
