Anlin vs. Milgard Windows: Product Lines, Glass and Warranties

Ask three California window contractors for a vinyl replacement quote and there is a good chance Anlin and Milgard will both be on the table. This page, part of our California window guide, compares them using what each company currently publishes. We install both, so we have no reason to tilt it. For more on each, see Milgard windows from Heritage Exteriors and Anlin Designer Black windows.

Two companies, one parent group

Anlin Windows & Doors describes itself as a replacement window and door manufacturer headquartered in Clovis, California, founded by Tom Vidmar in 1990. Its focus has always been replacement windows, sold through authorized dealers.

Milgard was founded in Tacoma, Washington in 1958, started with glass and aluminum windows, and today sells vinyl, fiberglass and aluminum products for both new construction and replacement across the western United States through Milgard Certified Dealers.

Both are now part of MITER Brands: Milgard says it joined in 2019, and Anlin's site describes it as a member of the same group. They continue to operate as separate brands with separate product lines and warranty documents. It does explain why Anlin's newest warranty document closely resembles Milgard's.

Product lines

The first difference is breadth. Anlin makes vinyl. Milgard makes vinyl, fiberglass and aluminum.

Rough counterparts: Anlin Panoramic against Milgard V300 Trinsic for a slim modern frame; Anlin Catalina and Del Mar against Milgard V400 Tuscany for a traditional, fuller frame. If you want something other than vinyl, such as fiberglass for a large sun-exposed opening or aluminum for a mid-century house, only Milgard offers it. See fiberglass versus vinyl and vinyl versus aluminum.

Both make sliding patio doors to match: Anlin's are the Malibu line, and Milgard offers doors in its Tuscany, Trinsic, fiberglass and aluminum series along with moving glass walls.

Glass packages

Anlin's marketing is built around named glass packages, which it lists on each collection page:

• Infinit-e (standard): three layers of low-E coating, described as suitable for all climates.
• SunMatrix (optional upgrade): four layers of low-E coating, described as ideal for warm to hot climates, with an easy-clean exterior coating.
• SunShield: a blue-gray tinted package for hot climates and glare.
• CoolShield: two layers, for mild climates, allowing more winter solar warmth.
• Luminance: one layer, for cold climates, with maximum visible light.
• QuadraTherm: an added interior-surface coating for more heat retention, combinable with the others.
• Sound Package: a noise-reduction option, standard on Del Mar.

Milgard organizes its glass options by series rather than under branded package names, so ask the dealer which low-E package is being quoted and get its certified figures.

How to use this in California: the valley and inland zones want a low solar heat gain package (in Anlin's terms, Infinit-e or SunMatrix); San Francisco and Tahoe have no prescriptive solar heat gain limit, so a higher-gain package can be the more comfortable choice there. Whatever the package is called, the test is the NFRC label. The prescriptive maximum U-factor for replacement windows is 0.27 across Northern California, the Central Valley and the Sierra, with SHGC of 0.23 or less in most zones; see what Title 24 requires and how to read the label. For which packages suit the valley, see the best energy-efficient windows for Sacramento, and for noise, types of soundproof windows.

Warranties: three documents to keep straight

This is the part most likely to be described wrongly on a sales call, because both companies changed their documents recently. Milgard's current warranties took effect 1 January 2026. Anlin's residential booklet applies to products sold after 1 July 2024, and its 100-line warranty to products made after 1 September 2026.

Transferring Anlin's warranty

Anlin's Double Lifetime coverage passes to one subsequent owner who also occupies the home, on a condition: Anlin must be notified of the transfer within 90 days of the change of ownership, with the names of both owners, the address and the date. If that notice is not given, the document says the warranty ends when the original purchaser no longer owns or occupies the home. If you are buying a house with Anlin windows, put this on your closing checklist. Anlin's site says transfers are handled through its Consumer Services Department.

Milgard's optional upgrade

Milgard's Full Lifetime Warranty Upgrade, listed for the V400 Tuscany, V300 Trinsic and C700 series, adds lifetime coverage of the glass seal and hardware, non-specialty glass breakage and all labor for the original owner-occupant. It must be purchased with the original order, it is not offered everywhere, and it does not transfer.

Coastal and wall-system exclusions

Anlin's booklet excludes corrosion from a salt-air environment, loss of hardware function in buildings within two miles of the ocean or a body of salt water, and products installed in buildings with a non-drainable EIFS or similar synthetic stucco system. Milgard's excludes corrosion and abnormal environments apart from a one-year term on stainless steel hardware. If you live near the coast, read our sibling guide on coastal windows before choosing hardware and finishes.

Making a claim

Anlin's documents direct you to the contractor who installed the product or to Anlin directly. Milgard's direct you to its service request page or phone line. Both newer documents ask for claims within 30 days of discovering a problem. Our sibling guides cover the process: how to make a window warranty claim and window warranties explained.

Color options

Both brands now offer dark exteriors on vinyl. Anlin's is a black capstock sold as Designer Black, which Anlin describes as a durable integrated color. Milgard lists Black Capstock among the exterior and interior colors for its Tuscany and Trinsic series, alongside exterior colors such as bronze, espresso and silver. Check which colors are available on the inside as well as the outside for the specific line, and note the finish warranty terms in the table above. Our sibling guide on dark window frames and heat covers what dark colors mean on a hot elevation.

How to choose between them

• You want a second-owner warranty and glass breakage included as standard: Anlin's Double Lifetime lines offer both, provided the transfer notice is given. Confirm the quote is not for a 100-designated product.
• You need fiberglass or aluminum for some openings: Milgard, since Anlin is vinyl only.
• You want the top Anlin collection: Del Mar is sold only through Anlin's Gold Star dealers, which narrows your choice of installer.
• The house is a rental: read the occupancy language. Anlin's Double Lifetime document is written for owner-occupied residences. Milgard's and Anlin's 100 documents give non-occupant owners 10-year terms.
• New construction or an addition: Milgard sells into new construction with its own warranty document; Anlin positions itself as a replacement manufacturer.

On most ordinary retrofit jobs both will perform well, and the installer matters more than the label. Ask each bidder for the collection or series by name, the glass package, the NFRC figures and which warranty document applies, then use how to compare window replacement quotes. For installed cost ranges see our cost page.

Noise claims and how to check them

Anlin says its Sound Package, standard on Del Mar and optional elsewhere, reduces outside noise by up to 50 percent compared with typical dual-pane windows, and that its Catalina, Coronado and Panoramic windows come with double-strength glass. Those are the manufacturer's figures. If noise is the reason you are replacing windows, ask either brand for the tested sound ratings of the specific unit and glass make-up, because that is the like-for-like number. Our page on types of soundproof windows covers which glass changes actually help.

Service territory and registration

Both brands are Western, and their newer warranties say so in the labor clause. Milgard provides skilled labor for 10 years only if the home is inside its service territory. Anlin's 100-line document does the same and lists its service territory as Arizona, California, Colorado, Hawaii, Nevada, Oregon, Utah and Washington. For a California house that is not a limitation.

Both invite you to register with the sales order number, and both say registration simplifies service; Milgard states it is not a condition of coverage. Anlin's registration form includes a warranty transfer option, and its FAQ says transfers are handled by calling its Consumer Services Department. Keep the order number: on a Milgard window it is printed between the panes in an upper corner, and Anlin puts it on a label whose position depends on the window type.

Questions to put to the dealer

1. Which collection or series is this, and for Anlin, is it a 100-designated product?
2. Which warranty document applies, and does it include accidental glass breakage?
3. Which glass package is quoted, and what are its NFRC U-factor and SHGC in this operating style?
4. Is the color a capstock or a coating, and what is the finish term?
5. Who installs, and what is the workmanship warranty in writing?
