Sliding Patio Doors: NT vs Andersen vs Pella vs Marvin

If you're a Central Texas homeowner shopping for a new sliding patio door, you've probably noticed pretty quickly that "sliding patio door" can mean a $2,000 vinyl door or a $20,000 wood-clad door, and everything in between. The brand on the sticker matters. The series within that brand matters even more.

At JP Exteriors, we install sliding patio doors from NT Windows, Andersen, Pella, and Marvin across Austin, San Antonio, and the surrounding suburbs. Each of these manufacturers makes good products, but they don't make one product. Every brand has a tiered lineup, and the series you choose determines the material, the energy performance, the maximum size, the customization options, and ultimately what the door is going to cost you.

This guide breaks down the major sliding patio door series from all four brands, so you can walk into your consultation knowing the difference between an Andersen 100 Series and an A-Series, or a Pella 250 and a Reserve Traditional. Let's get into it.

A quick note on what "sliding" means

Industry-wise, you'll see these doors called sliding, gliding, or rolling. Andersen calls theirs "gliding patio doors." Marvin and Pella usually say "sliding." NT goes with "sliding glass door." They all describe the same thing: a door where one or more panels slide horizontally on a track instead of swinging open like a French or hinged door. For this guide, we'll say sliding throughout.

NT Windows: KD650 and Studio

NT Windows is a Texas-based vinyl manufacturer headquartered in Burleson. For Central Texas homeowners, that local manufacturing is a real advantage on lead times, and the pricing tends to come in well below the national premium brands.

NT offers two main sliding patio door series:

NT KD650

The KD650 is NT's standard vinyl sliding patio door. Two-panel configuration only, available in standard heights of 6'8" and full sizes from 5' to 8' wide. NT also offers custom call sizes (5'x6'10", 6'x6'10", 8'x6'10", and a few others) for situations where the rough opening doesn't match a standard size, which happens often in older Austin neighborhoods.

Standard frame colors are white, almond, sandstone, and clay, with bronze and black available as upgrades. Built-in between-the-glass blinds are available on most sizes (though not on the larger no-blinds-available 6'x8', 8'x6'8", and 8'x8' configurations). Other options include security bolts, premium hardware, colored frames, and grids.

Best for: budget-conscious replacements, rentals, builder-grade upgrades, and homeowners who want a solid vinyl door without paying for a national brand premium.

NT Studio

The Studio is NT's premium sliding patio door. Larger frame profile, beefier construction, more substantial hardware. Same panel configuration (two-panel) but with True/Custom sizing available in 5'x6'10", 6'x6'10", and 8'x6'10". The Studio uses an ERGO bar for the security bolt and offers Clear Oxidized as the standard finish, with white, black, and brown as options.

Best for: homeowners who want a vinyl door but want it to feel and look more substantial, or who need a custom call size and want NT's pricing rather than stepping up to a national brand.

Andersen: 100, 200, 400, A-Series, E-Series

Andersen has the broadest lineup of any of the four brands, with five distinct sliding patio door series. Each one targets a different price point and material preference.

Andersen 100 Series Gliding Patio Door

The 100 Series is Andersen's entry point. It's made of Andersen's proprietary Fibrex composite material, which is a blend of wood fiber and thermoplastic polymer. Andersen markets it as twice as strong as vinyl, and it does hold up better in dark colors under direct Texas sun than standard vinyl does. Two-panel only, available in 5', 6', and 8' widths and 6'8", 6'11", and 8' heights.

Best for: homeowners who want better-than-vinyl performance without stepping up to wood pricing, especially in homes where dark exterior frame colors matter.

Andersen 200 Series (Narroline and Perma-Shield)

The 200 Series is a streamlined wood collection. Two flavors:​

  • Narroline: wood interior with vinyl exterior, narrow frame profile that maximizes glass area and views
  • Perma-Shield: vinyl-clad on both interior and exterior, more durable for high-moisture or high-maintenance situations.

The 200 Series is a step up from the 100 in materials and customization, but Andersen limits the options compared to the 400 Series to keep it positioned as a value-oriented wood door.

Andersen 400 Series Frenchwood Gliding Patio Door

The 400 Series is Andersen's best-selling patio door. Wood interior, vinyl-clad exterior, and the widest range of customization in the mid-tier (sizes, colors, grid patterns including Full Divided Light, hardware finishes). Available with between-the-glass blinds, which is a popular option in Austin homes where dust and pet hair on traditional blinds is a constant fight.

Best for: homeowners who want real wood interior in their patio door, plenty of customization, and a brand with strong resale recognition.

Andersen A-Series Gliding Patio Door

The A-Series is part of Andersen's Architectural Collection. Wood interior protected by a fiberglass and Fibrex exterior, with thicker glass and a more refined sightline than the 400 Series. This is Andersen's best-performing gliding patio door from a structural and energy standpoint, and the most architecturally intentional in look. Designed in collaboration with architects, with details like glass setback and grid sizing that the lower series don't offer.

Best for: custom homes, architecturally significant remodels, and homeowners who want the design language to read "intentional" rather than "off the shelf."

Andersen E-Series Gliding Patio Door

The E-Series is Andersen's most customizable line. Wood interior with extruded aluminum exterior, which gives you essentially unlimited color and finish options on the outside. Available in single, two-panel, and four-panel configurations, with transom windows that can stack on top to reach 10 to 12 feet of total opening height. Most expensive Andersen sliding door by a wide margin.

Best for: high-end custom builds where the patio door needs to match a very specific architectural vision.

Pella: Encompass, 250, Lifestyle, Impervia, and Reserve

Pella's lineup mirrors Andersen's tier structure but uses different materials at each price point.

Encompass by Pella

Encompass is Pella's competitively priced vinyl line. Easy-care, energy-efficient, and the most budget-friendly Pella sliding patio door.

Best for: rental properties, builder-grade work, and homeowners who want the Pella name on a tighter budget.

Pella 250 Series

The 250 Series is Pella's mid-range vinyl. Stronger frame construction than Encompass, with options for built-in blinds and an integrated footbolt. Three-panel configurations are available, which Encompass doesn't typically offer.

Best for: vinyl buyers who want options like blinds-between-the-glass without jumping to fiberglass or wood.

Pella Lifestyle Series

The Lifestyle Series is Pella's wood patio door, with clad exterior options. Pella positions it as their best wood patio door for the combination of energy, sound, and value. Available in two, three, and four-panel sliding configurations. Built-in blinds and shades, retractable screens, and a wide range of grid patterns.

Best for: homeowners who want wood patio doors with strong energy performance and don't need the full custom treatment of the Reserve line.

Pella Impervia

Impervia is Pella's fiberglass line. Pella's proprietary fiberglass is engineered to handle extreme temperature swings, which makes Impervia a real consideration in Texas, where a door can hit 150 plus degrees on the exterior in summer and still need to seal tight in a January cold snap. Impervia features a low-profile sill (Pella claims about 45 percent lower than average), multiple locking mechanisms, and a Secure Vent Lock that allows the door to be locked in a partially-open ventilation position.

Best for: homeowners who want maximum durability and energy performance without going full wood, especially in homes with heavy daily use.

Pella Reserve (Traditional and Contemporary)

The Reserve line is Pella's top-tier wood collection, split into two design languages:​

  • Reserve Traditional: historical authenticity, wider stiles and rails, classic grid patterns, divided light options
  • Reserve Contemporary: narrow sightlines, modern hardware, minimalist design.

Twenty exterior color options. Retractable screens. Maximum customization.

Best for: high-end remodels, historic home restorations, and modern custom builds where the patio door is a statement piece.

Pella Hurricane Shield Series

Worth mentioning briefly: Pella also makes a Hurricane Shield Series for coastal markets. Not commonly specified inland in Central Texas, but it exists if a homeowner wants impact-rated glass for storm protection.

Marvin: Essential, Elevate, Signature Ultimate, Signature Modern

Marvin's lineup is structured around three collections, with multiple sliding patio door products in each.

Marvin Essential Sliding Patio Door

The Essential collection is built with Ultrex fiberglass inside and out. Marvin claims their Ultrex is roughly eight times stronger than vinyl and three times stronger than wood-vinyl composites. Available in two and three-panel configurations, up to 8 feet wide by 8 feet tall (two-panel) or 9 feet wide by 8 feet tall (three-panel). Limited but well-curated color palette.

Best for: homeowners who want fiberglass durability, clean lines, and a streamlined option set without stepping up to the wood collections.

Marvin Elevate Sliding Patio Door

The Elevate collection pairs warm wood interiors with Ultrex fiberglass exteriors. You get the look and feel of real wood inside the home and the low-maintenance durability of fiberglass on the weather side. Marvin offers Elevate in sliding patio, sliding French, swinging French, and inswing/outswing configurations.

Best for: homeowners who want wood interiors at a more accessible price than the Signature collections.

Marvin Signature Ultimate Sliding Patio Door

The Signature Ultimate is Marvin's flagship wood patio door. Wood interior with extruded aluminum cladding on the exterior. Configurations up to 16 feet wide and panels up to 9 feet tall, available in two, three, and four-panel layouts. Slim 3-inch stiles and rails for a contemporary look, or wider rails for a more traditional French aesthetic. Hidden Lock Status Sensor option for smart home integration.

Best for: large openings, architectural builds, and homeowners who want the pinnacle of wood patio door construction.

Marvin Signature Modern Sliding Door

The Signature Modern collection uses high-density fiberglass and is designed specifically for modern architecture. Low-gloss aluminum interiors, black spacer bars, hidden fasteners, narrow sightlines.

Best for: contemporary custom homes, modern remodels, and projects where the door needs to feel architecturally minimalist.

Side-by-side: which series compete with which

If you're cross-shopping these brands at the same price point, here's how the tiers roughly line up:

Entry tier (vinyl or composite): NT KD650, Andersen 100 Series, Pella Encompass, Pella 250 Series, Marvin Essential (a step up in material).

Mid tier (premium vinyl, fiberglass, or value wood): NT Studio, Andersen 200 Series, Pella Lifestyle Series, Pella Impervia, Marvin Essential, Marvin Elevate.

Upper tier (wood with clad exterior): Andersen 400 Series Frenchwood, Pella Reserve Traditional, Marvin Elevate.

Premium tier (architectural and custom): Andersen A-Series, Andersen E-Series, Pella Reserve Contemporary, Marvin Signature Ultimate, Marvin Signature Modern.

What matters most in Central Texas

Three considerations come up the most in our consultations:

Heat and UV resistance: Texas summers are brutal on vinyl in dark colors. If you're set on a black or bronze frame, fiberglass (Marvin Essential, Pella Impervia) or composite (Andersen 100) will hold up significantly better than a standard vinyl door. NT's vinyl is rated for the Texas climate, but the dark color upgrade is best paired with light-colored exposures or shaded patios.

Storm performance: Central Texas hail and high-wind events are no joke. Insurance carriers increasingly want documentation of impact-rated or wind-rated products. Andersen and Pella both offer storm-rated versions of several series. Marvin's Ultrex products perform well in wind testing.

Local style fit: Austin's mix of mid-century modern, Hill Country traditional, modern farmhouse, and contemporary new builds means there's no single "right" patio door style. Modern minimalist homes lean toward Marvin Signature Modern or Pella Reserve Contemporary. Hill Country and traditional homes pair well with Andersen 400 Series or Pella Reserve Traditional. Production builds and budget-conscious replacements are the sweet spot for NT KD650 and Andersen 100.

How to choose

  1. What's your budget per opening? Vinyl entry-level lands in the $2,000 to $4,000 range installed. Wood premium can land north of $15,000 per opening.
  2. What size opening do you have? Standard 6'8" rough openings open up the most options. 6'10" or 8' tall openings narrow the field to series with custom sizing.
  3. What material do you want to live with? Vinyl is the easiest, fiberglass is the most durable, wood is the warmest looking but requires interior care.
  4. How important is architectural detail? If grid patterns, divided lights, narrow sightlines, and exact color matching matter, the Architectural and Signature collections are where you want to be.

    5. The series you choose comes down to four questions:

If you're not sure where you land on those four, that's exactly what the in-home consultation is for. We bring physical samples of multiple series and walk you through the trade-offs in person.
