There’s nothing worse than standing in your half-built place, staring at gaps where the aluminum sliding glass doors should go, and feeling unsure about what to choose.
I remember feeling scared. What if I picked doors that leaked or got stuck? What if they looked cheap and didn’t last?
The more I searched, the more stressed I got. Every company promised they were the best. I didn’t know who to trust.
So I started digging, I called up suppliers and asked hard questions about how strong their frames were. Looked at old projects, because I didn’t want regrets later.
That’s how I came up with this list of the top 8 aluminum sliding glass door makers. It’s the same list that helped me sleep better at night.
If you’re building a villa, hotel, or even a greenhouse, this guide will give you a clear place to start. It’ll help you pick doors you can feel good about.
So let’s dive in!

1. Andersen Corporation
Andersen started back in 1903 in Bayport, Minnesota. It began as a small family business near the river. They focused on building good windows and doors that people could rely on. What’s nice is how much they still care about people. Many workers have stayed there for 30 or even 40 years. That says a lot. It shows they treat their team well, and folks are happy to stick around.
What I like about them is that it makes you feel like they’re not just another huge company chasing money. They want to build doors that last and keep families happy for a long time.
Today, they’ve grown into one of the biggest door and window companies in North America. But they still make many parts themselves. This helps them keep control so things stay strong and fit right.
Product
- Aluminum Sliding Doors: They offer sleek, large-panel sliding doors with clean lines and smooth operation. Perfect for villas or hotel suites that open to patios or gardens.
- Multi-Slide and Folding Door Systems: Great for wide openings and open-air transitions in high-end builds. These systems can be customized to meet different layout needs.

Research and Development
- Fibrex® Frame Material: This is Andersen’s own composite that combines PVC and reclaimed wood fiber. It’s stable, long-lasting, and doesn’t warp like pure vinyl.
- SmartSun™ Glass: This glass blocks UV rays while letting in plenty of daylight. It’s a smart option for sun-facing rooms or large-glass designs.

Final Thoughts
Andersen Windows is best for businesses working on larger builds that need reliable supply, certified systems, and wide configuration options across regions. But if your project involves highly customized decorative looks or limited space for dealer coordination, you may prefer a smaller, design-first supplier.
2. Pella Corporation
Pella was started in 1925 in Pella, Iowa by Pete and Lucille Kuyper. I appreciate that they began with a simple roll‑up insect screen but grew into a major window and door maker while staying family-owned. Today, they employ about 10,000 people across 18 U.S. manufacturing plants.
Over the years, Pella evolved by investing in people and products without losing its roots. They focus on hiring diverse teams, including a high percentage of English language learners in some plants, something rare in manufacturing. For you, that means a supplier with scale, consistent quality, and expanding capacity in fast-growing regions.

Final Thoughts
Pella is great for businesses aiming for innovation‑driven, energy‑efficient doors and smart features in commercial or hospitality builds. But if your project emphasizes ultra‑high design customization or sourcing from a narrow regional footprint, a boutique fabricator might suit you better.
3. Vallisco
It may sound biased, but this one is one of my favorites. There’s something about Vallisco that feels more approachable than many big global manufacturer. Even though they officially set up as their own company in 2024, they’re backed by 24 years of doors and windows experience under Qeeka Home.
They operate a factory-direct model with high production discipline, and serve architecture and developer clients with precision and transparency. Vallisco also holds CE and ISO certifications, important when you’re sourcing with international standards in mind.
Product

Final Thoughts
Vallisco is best for businesses sourcing modern, factory-direct aluminum sliding glass doors with international compliance and OEM customization capabilities. But if your project needs a wide selection of pre-designed models, you may find their catalog not as massive compared to larger legacy suppliers.
4. The Sliding Door Company
The Sliding Door Company was founded in 2005 in Los Angeles, California. I like how they began with a simple mission, to bring elegant glass doors direct from their factory to businesses needing smart space solutions. You’ll find that they operate across North America with around 19 showrooms and a team between 50 and 200 employees.
They hold U.S. patent #7,647,729 and follow industry standards via AAMA and USGBC certifications, which helps when you’re aiming for reliable code compliance.
Over time, they’ve built strong relationships with big clients like Hilton hotels, Starbucks, HP, and WeWork, so you know they’re used to large-scale specs and repeat business.
Product
- Interior Glass Sliding Doors: They offer doors that glide smoothly and look sleek, perfect for room dividers and office suites. Your engineering team can plan for clean transitions and reliable hardware.
- Barn & Pocket Doors: These systems save floor space by sliding into cavities or mounting flush. They’re ideal for layouts in boutique hotels or villas with flexible layouts.

- Address: 1200 N La Brea Avenue, West Hollywood, CA 90038, USA
Final Thoughts
The Sliding Door Company is best for businesses focused on clever interior solutions with clean aesthetics and minimal supply-chain layers. But if your project needs heavy-duty exterior doors or impact-rated systems, you’ll want to pair them with a supplier experienced in large-scale weatherproof builds.
5. Milgard Windows & Doors
Milgard was founded in 1958 in Tacoma, Washington by Maurice Milgard Jr. and his son Gary. I like how they stayed true to the original craft while growing steadily, starting from a small glass shop to a firm with over 4,300 employees across multiple manufacturing plants in the western U.S.
They serve builders, architects, and commercial contractors through more than 3,300 dealer locations. You’ll see they use certifications like Energy Star and AAMA standards, and they offer a full lifetime warranty, which helps give you confidence in long-term projects.

- Address: 1010 54th Ave E, Tacoma, WA 98424, USA
Final Thoughts
Milgard is best for businesses working on west-coast commercial or residential builds that need warranty-backed products and regional climate adaptation. But if your project requires passive-house certification or global thermal performance specs, you may want a more specialized supplier for those performance levels.
6. Therma-Tru Doors
Therma‑Tru was founded in 1962 in Maumee, Ohio, and has grown into a leader in entry and patio doors. I like how they focus on craftsmanship while expanding, they now employ around 5,000 staff and work with a network of certified installers across the U.S. You’ll find they hold AAMA and NFRC certifications, and many of their doors meet ENERGY STAR requirements.
I’ve seen their aftermarket support remain strong even during high-volume seasons. They offer extended warranties and dealer training programs for consistent installations. For you, that signals a partner who invests in both product and service reliability.

Final Thoughts
Therma‑Tru is best for businesses that want patio or entry door systems with elegant looks, secure hardware upgrades, and robust field support. But if you need ultra-wide sliding or impact-rated aluminum systems, you may find more specialized performance with companies focused solely on extensive sliding glass layouts.
7. Schüco
Schüco was founded in 1951 in Bielefeld, Germany by Heinz Schürmann. I admire how a small metal workshop transformed into a global supplier with around 6,850 employees and service reach in over 80 countries. They specialize in aluminum, PVC‑U, and steel systems for windows, doors, and building façades.
When I think of Schüco, I see a company serious about both performance and design. They work with 12,000 fabricator partners and offer digital tools, BIM support, and design training. That makes them a strong choice when your projects demand consistent output across regions and support for technical planning.

Final Thoughts
Schüco is best for businesses working on high-end architectural builds that need ultra-slim aluminum sliding systems with tested energy, security, and automation features. But if your project budget focuses purely on cost rather than system integration and design impact, a simpler supplier may be more appropriate.
8. Western Window Systems
I didn’t truly appreciate how big sliding doors could change a space until I saw a Western Window Systems install in person. The room went from looking normal to feeling like part of the outdoors, almost like the walls disappeared. Western got its start in Phoenix, Arizona, and while they’ve grown a lot, they’ve kept that desert spirit of wide-open design.
They offer showrooms across North America and support fabricators and design teams with CAD/BIM tools. If your projects involve hotels, villas, or institutional builds that need expansive openings, their design support and production scale can help keep you on track.
