Andersen Sliding & French Patio Doors

Fibrex® material is a proprietary composite developed by Andersen that combines the strength and stability of wood with the low-maintenance performance of vinyl. It’s made from a blend of reclaimed wood fiber and thermoplastic polymer, creating a material that’s twice as strong as vinyl and designed to perform beautifully for decades.

Unlike wood, Fibrex® won’t rot, warp, or require painting. And unlike vinyl, it won’t bow or crack under extreme temperature changes. It also allows for narrower frames and more glass area, giving you better views and more natural light.

Every Renewal by Andersen window is built with Fibrex® because it provides the perfect balance of durability, energy efficiency, and lasting beauty, with minimal upkeep required.

Renewal by Andersen windows and doors are engineered from the ground up for exceptional energy performance in every season. It starts with our exclusive Fibrex® material, which insulates 700 times better than aluminum and helps reduce thermal transfer, keeping your home warmer in winter and cooler in summer.

We also use High-Performance™ Low-E4® glass and other advanced glass options designed to block heat, UV rays, and cold air, without sacrificing natural light. Each window is custom-built to fit your home, which eliminates air leaks and drafts that waste energy.

Combined with professional installation by certified experts, our products meet or exceed ENERGY STAR® standards, helping homeowners lower utility bills, reduce environmental impact, and enjoy year-round comfort.

Renewal by Andersen Signature Service is our promise of a seamless, start-to-finish window and door replacement experience, built around superior products, professional installation, and exceptional customer care.

Unlike companies that sell windows made by others, Renewal by Andersen manages the entire process in-house. That means one accountable partner for everything – design consultation, custom manufacturing, installation, and warranty coverage.

That accountability shows up on installation day. A Master Installer reviews the project with you before work begins so you know exactly how your job will proceed, and when the work is finished, the crew completes a detailed point-by-point inspection of every window before the project is signed off.

Our Signature Service ensures you get the best combination of expert craftsmanship and attentive service, backed by one of the strongest limited warranties in the industry. It’s a stress-free experience designed to make home improvement simple, reliable, and rewarding from beginning to end.

Renewal by Andersen offers a selection of beautiful, energy-efficient patio doors designed to enhance your home’s comfort, functionality, and style. Each door is custom-built for a perfect fit and features durable materials, smooth operation, and superior weather performance.

Available styles include:

• Hinged French Patio Doors – A timeless design that opens inward or outward, adding classic charm and elegance to any home.
• Contemporary Sliding Patio Doors – Sleek, space-saving doors with wide glass panels for expansive views and effortless operation.
• French-Style Sliding Patio Doors – The look of traditional French doors combined with the convenience of a sliding design.

All Renewal by Andersen patio doors feature energy-efficient glass, Fibrex®-framed sashes, and custom hardware and color options to match your décor. Whether you prefer a modern look or a traditional feel, each door is designed for lasting beauty, smooth performance, and exceptional energy savings.

Renewal by Andersen entry and patio doors are built with the same energy-saving innovation found in our replacement windows. Each door is engineered to seal tightly against drafts, reduce heat transfer, and maintain consistent indoor temperatures year-round.

Our doors feature High-Performance™ Low-E4® glass options that help keep your home cooler in summer and warmer in winter by blocking unwanted heat gain and loss. The frames are made from durable, insulating Fibrex® composite material or energy-efficient wood cores with weather-resistant exteriors.

Every door is custom-sized and professionally installed to ensure a precise fit, eliminating the gaps and air leaks that can waste energy. Together, these features deliver lasting comfort, lower utility bills, and superior performance.

The main difference between sliding patio doors and French doors lies in how they operate and the style they bring to your home.

Sliding patio doors glide smoothly along a track, making them ideal for areas where space is limited, like decks or patios where you don’t want a swinging door. They offer a sleek, modern look with large glass panels that maximize natural light and outdoor views.

French doors, on the other hand, feature two hinged panels that swing open either inward or outward. They’re known for their classic, elegant appearance and can create a wide, welcoming entryway that enhances both traditional and transitional homes. Because a French door swings rather than slides, there’s also no track running across the floor of the opening — a smaller detail that matters for accessibility and for moving furniture in and out.

Both styles from Renewal by Andersen are built with energy-efficient glass, durable materials, and customizable finishes, so you can choose the look and operation that best fits your home’s layout and personality.

Renewal by Andersen offers one of the strongest limited warranties in the window and door industry, giving homeowners lasting peace of mind. Every product and installation is backed by comprehensive coverage that includes:

• Glass: Coverage for 20 years against defects in material and workmanship, including issues like seal failure that cause fogging or streaking.
• Frame & Sash: Coverage for 20 years against defects in the Fibrex® material and all factory finishes.
• Hardware: Coverage for 10 years on locks, lifts, handles, and other functional components.
• Installation: Each window and door is installed by Renewal by Andersen’s certified installers and comes with a 2-year installation warranty, ensuring proper fit and performance.

This combination of product and installation protection means your investment is safeguarded – and if service is ever needed, it’s handled directly by Renewal by Andersen professionals, not a third party.

With this warranty, homeowners can count on long-lasting performance, beauty, and confidence in every window and door we install.

Renewal by Andersen is committed to sustainability at every stage, from product design to installation. Our goal is to create beautiful, energy-efficient windows and doors that help homeowners reduce their environmental impact without compromising on performance or style.

Key sustainable practices include:

• Fibrex® Material Innovation: Our exclusive Fibrex® composite contains 40% reclaimed wood fiber by weight, much of it reclaimed directly from Andersen’s own manufacturing processes. This reduces waste and makes Fibrex® twice as strong as vinyl, so it lasts longer and requires less replacement over time.
• ENERGY STAR® Certified Performance: Renewal by Andersen products meet or exceed ENERGY STAR® criteria, helping homeowners lower energy use and greenhouse gas emissions.
• Efficient Manufacturing: Our production facilities are designed for waste reduction, responsible sourcing, and recycling, diverting millions of pounds of material from landfills each year.
• Long Product Lifespan: Durable materials and expert installation mean fewer replacements, a key part of long-term sustainability.

By combining smart design, responsible manufacturing, and lasting performance, Renewal by Andersen helps create homes that are more comfortable, energy-efficient, and environmentally responsible.

When we say that Fibrex® is made from reclaimed materials, it means that much of the wood fiber used to create Fibrex® comes from reclaimed sawdust and wood shavings that would otherwise go to waste in Andersen’s manufacturing process. These reclaimed fibers are blended with a thermoplastic polymer to form a strong, durable composite material that delivers the beauty of wood and the low maintenance of vinyl.

By reusing materials that would normally be discarded, Renewal by Andersen helps reduce landfill waste and conserve natural resources, all while producing a window frame that lasts longer and performs better than traditional materials.

Every Fibrex® window frame is:

• Twice as strong as vinyl, maintaining its shape and tight seal in all temperatures.
• Resistant to rot, decay, and warping, eliminating the need for painting or staining.
• Engineered for sustainability, with up to 40% reclaimed wood fiber by weight.

In short, Fibrex® is a material that’s better for your home and better for the planet.

No. Renewal by Andersen of Eastern NY does not subcontract installation work to third-party crews. Every window and door installation is performed by our own trained professionals – Certified Master Installers who work exclusively on Renewal by Andersen projects.

This is a key difference from many home improvement companies that rely on independent subcontractors who may be juggling multiple brands and jobs. Our installers know our products inside and out because it’s all they work with, and they’re held to Renewal by Andersen’s quality and customer service standards on every job.

Using our own installation teams also means a single point of accountability for your project. If a question or service need arises after installation, you contact Renewal by Andersen of Eastern NY directly, not a separate contractor who may have moved on to other work.

From your first consultation to your last warranty call, you’re working with one company and one team.

Andersen Corporation has been in business for over 120 years, making it one of the most established and trusted names in the window and door industry. The company was founded in 1903 by Danish immigrant Hans Andersen and his family in Hudson, Wisconsin, with a commitment to quality craftsmanship and innovation that continues to this day.

Renewal by Andersen is the full-service window and door replacement division of Andersen Corporation, bringing that same heritage of quality and innovation directly to homeowners. While Andersen windows are sold through retail and wholesale channels, Renewal by Andersen provides a complete start-to-finish experience (consultation, custom manufacturing, professional installation, and warranty support) all handled by one company.

When you choose Renewal by Andersen of Eastern NY, you’re partnering with a locally operated team backed by more than a century of American manufacturing expertise. That combination of national strength and local accountability is what sets us apart.

Certified Master Installers are Renewal by Andersen’s trained, in-house installation professionals – not subcontractors. Every installer goes through a rigorous training program to ensure they meet Renewal by Andersen’s exacting standards for quality, precision, and customer care.

This matters because even the best window or door won’t perform properly if it’s not installed correctly. Certified Master Installers are trained to take precise measurements, prepare openings properly, install products to manufacturer specifications, and ensure every window and door seals tightly and operates smoothly.

They also treat your home with respect, using protective coverings on floors and furniture, performing a thorough cleanup, and completing a detailed final inspection before the job is done.

Because Renewal by Andersen of Eastern NY uses its own Certified Master Installers rather than outsourcing to third-party contractors, there’s one team accountable for your entire project, from manufacturing through installation and warranty service.

Yes! Renewal by Andersen has been ranked #1 in Customer Satisfaction among Window and Patio Door Manufacturer Brands by J.D. Power for six consecutive years (2020–2025).

The J.D. Power U.S. Windows and Patio Doors Satisfaction Study is based on feedback from thousands of real homeowners who have completed window and door replacement projects. The study evaluates companies across several dimensions, including durability, performance, features, ease of use, appearance, value relative to price paid, and overall level of trust.

This recognition isn’t based on marketing claims – it’s earned through the actual experiences of homeowners across the country. Being ranked #1 for six years running reflects Renewal by Andersen’s consistent commitment to quality products, professional installation, and exceptional customer care.

As part of the Renewal by Andersen family, our Eastern NY team delivers the same nationally recognized quality and Signature Service that earned this distinction, backed by local expertise and personal attention.

Renewal by Andersen of Eastern NY serves homeowners throughout the Capital Region and Hudson Valley, with locations in Schenectady and Middletown. That includes Albany, Troy, Clifton Park, Saratoga Springs, Latham, Newburgh, Poughkeepsie, and the surrounding communities.

Renewal by Andersen windows and doors are sold and installed exclusively through local Renewal by Andersen locations — they aren’t available through big-box retailers, online sellers, or independent contractors. That’s what allows one team to stand behind the product, the installation, and the warranty together.

If you’re not sure whether your address falls within our service area, give us a call or send us a message. We’ll confirm right away, and if your home is served by a different Renewal by Andersen location, we’ll point you to the right team.

No. A properly built and professionally installed patio door is every bit as secure as any other exterior door on your home — and in most cases, more secure than the aging door it replaces.

Renewal by Andersen patio doors are engineered with reinforced multi-point locking hardware that secures the panel at several points along the frame rather than a single latch. Sliding doors include an anti-lift design so the panel can’t be forced off its track, and French patio doors use a heavy-duty mortise lock system. Tempered safety glass is standard, with impact-resistant options available.

Installation matters just as much as hardware. Because every door is custom-measured for your opening and installed by our Certified Master Installers, there are no shims, gaps, or loose frames for someone to pry against — the weak points that make older patio doors vulnerable in the first place.

The result is a door that opens your home to more light and easier access to your outdoor space without asking you to trade away peace of mind.

Yes. Swapping a sliding glass door for a hinged French patio door is one of the more popular changes homeowners make, and in most homes it’s straightforward.

Because every Renewal by Andersen patio door is custom-built to your opening, we’re not limited to replacing what’s already there with the same style. Your design consultant will measure the existing opening and confirm what will fit — most standard slider openings accommodate a French door directly, and where the opening needs adjustment, our installers handle the framing as part of the project.

The change is worth considering if you want a wider clear opening for moving furniture or hosting, a more traditional look, or a threshold without a track running underfoot. If you’d rather keep the space-saving footprint of a slider, we can also replace it with a new, better-sealing sliding door.

Either way, you’ll see the options side by side during your free in-home consultation, so you can compare the look, the operation, and the cost before deciding.
