A few years back, I ordered a large batch of custom doors for a new project, only to find out half of them didn’t meet spec and couldn’t be installed on-site.
That headache taught me one thing: not all manufacturers know how to serve business clients who need precision and speed.
Since then, I’ve worked with dozens of vendors, and I’ve learned which ones consistently get it right, from quote to delivery to after-sales support.
This article walks you through the top 7 window and door manufacturers I’d personally recommend for commercial projects. It’s built to save you time and help you avoid costly delays.

1. Andersen Corporation
I’ve worked with a lot of window and door companies over the years, but Andersen has always stood out. Founded back in 1903, they’ve grown into North America’s largest window and door manufacturer—and not by accident.
Andersen’s headquarters is based in Bayport, Minnesota, and they’ve built up a strong reputation by consistently delivering quality, reliability, and service. With over 12,000 employees and more than 30 manufacturing sites, distribution centers, and retail outlets, they’re a powerhouse in the industry.
What makes Andersen even more appealing is their innovative Fibrex® material and their multi-channel approach that supports both large-scale projects and single replacements. They cover everything from new residential builds to commercial work.
Headquarter: Bayport, Minnesota, USA

Key Products
- Windows of All Kinds: From double-hung and casement to awning and specialty shapes, Andersen offers a full lineup to fit nearly any architectural need or personal taste. They’ve made it easy to match function with style.
- Doors for Every Space: They cover patio doors, storm doors, entry doors, and even massive folding or multi-slide glass wall systems. Whatever your opening, Andersen probably has a solution.
- Fibrex® Composite Windows: This is their signature material—made from reclaimed wood fiber and thermoplastics. It’s strong, energy-efficient, and practically maintenance-free.
- Wood-Framed Series: Their 400, A-Series, and E-Series lines feature high-end wood interiors and protective exterior cladding. They strike the right balance between classic design and modern performance.
- Vinyl and Aluminum Options: Andersen also makes budget-friendly vinyl and aluminum models for light commercial jobs or value-driven residential builds.
Certifications and Compliance Standards
- ENERGY STAR® Partner: Andersen is a longtime ENERGY STAR partner and has earned Partner of the Year recognition. Their products meet strict energy efficiency standards across all U.S. climate zones.
- NFRC Certified: Andersen products are certified by the National Fenestration Rating Council. Each unit carries ratings for U-Factor, Solar Heat Gain Coefficient, and Visible Transmittance to help buyers compare energy performance.
- WDMA Hallmark Certification: Andersen participates in the Window & Door Manufacturers Association Hallmark Program. This ensures their products are tested and audited for structural integrity and consistent manufacturing quality.
- AAMA Compliance: Andersen meets the standards set by the American Architectural Manufacturers Association. That means their windows and doors are built to handle real-world weather and performance demands.
- AIA Continuing Education Provider: Andersen is an approved education provider through the American Institute of Architects. They regularly host webinars and training sessions on energy codes, design trends, and commercial window applications.
Minimum Order Quantity
One thing I appreciate about Andersen is their flexibility when it comes to order size. For contractors or businesses working through a dealer, there’s usually no strict MOQ, but larger orders often come with better pricing and support. For commercial projects, you’ll work through formal quotes that reflect the full project scope.
Procurement Channels
- Homeowners & DIY Buyers: Products can be purchased directly from Andersen’s online store or through major retailers like The Home Depot. Great for small-scale or one-off needs.
- Contractors & Builders: Andersen works with a wide network of authorized dealers and distributors. These pros provide quotes, project support, and access to the full product catalog.
- Full-Service Replacement: Renewal by Andersen offers a start-to-finish window and door replacement service. They handle everything from consultation to installation, making it a hassle-free option.
Takeaway
Andersen Corporation has scale, service, and product diversity on its side. Their Fibrex material and high-end wood lines give you premium choices with long-term reliability. That said, some of their premium series can stretch your budget if you’re cost-sensitive.

2. VELUX Group
VELUX isn’t trying to be everything to everyone, and that’s exactly why they dominate their space. Since 1941, they’ve focused on just one thing: bringing more daylight and fresh air into buildings through the roof.
Founded in Denmark and still headquartered there today, VELUX has grown into the global leader in skylights and roof windows. With over 11,000 employees and operations in more than 40 countries, they’ve turned a niche into an empire.
Instead of chasing every trend in fenestration, VELUX doubles down on their expertise. When you need overhead light, ventilation, or a roof window that doubles as a balcony, this is the brand most architects and builders turn to first.
Headquarter: Hørsholm, Denmark
Website: https://www.velux.com
Key Products
- Skylights: This is VELUX’s bread and butter. From fixed skylights to venting models (solar, electric, or manual), these products are designed for durability, leak protection, and beautiful natural light.
- Sun Tunnel® Skylights: A smart solution when a full skylight isn’t feasible. These use a reflective tunnel to bring daylight into areas like hallways, bathrooms, or closets.
- Roof Windows: Built for spaces where the window is within reach, such as attics and lofts. They come in several designs, including top-hinged, center-pivot, and even a balcony-style window (CABRIO®) that opens outward into a small patio.
- Commercial Skylights: Designed for large buildings, these modular systems are perfect for schools, offices, and public spaces where large spans of daylighting are needed.
- System Accessories: From blackout blinds and shades to flashing kits that ensure watertight installation, VELUX’s accessory lineup rounds out a complete roof-window system.
Certifications and Compliance Standards
- ENERGY STAR® Certified: Most VELUX skylights sold in the U.S. meet ENERGY STAR requirements. Some models even earn the “Most Efficient” label for peak performance.
- NFRC Certified: Every U.S.-sold product includes NFRC performance data, providing verified info on U-Factor, SHGC, and VT for side-by-side comparisons.
- ISO 14001 Certified: Their environmental management system is third-party certified. This reflects their efforts in sustainable production and waste reduction.
- CE Marking: All European-market products carry the CE mark, confirming compliance with EU health, safety, and environmental regulations.
- EcoVadis Platinum Medal: In 2025, VELUX was ranked in the top 1% of companies globally for sustainability. That’s a big win for ethics and environmental leadership.
- WDMA Hallmark & IAPMO-ES: U.S. products meet top industry standards for quality and performance under both WDMA and Uniform-ES evaluations.
Minimum Order Quantity
VELUX makes it easy to buy, whether you’re replacing one skylight or outfitting a whole building. If you’re a homeowner, you can buy a single unit through a local dealer or certified installer. For larger residential or commercial jobs, you’ll work through a regional distributor or sales rep. Pricing and logistics are handled based on your project scope, with no fixed MOQ beyond the product availability for your region.
Procurement Channels
- Dealers and Distributors: VELUX products are sold through a global network of building material dealers and roofing suppliers. These channels are trained in product selection and support.
- VELUX Certified Installers: These professionals are factory-trained and vetted. They offer installation that meets the company’s strict standards, which helps with warranty eligibility and long-term performance.
- Design and Pro Consultation: For larger projects, VELUX advisors can assist directly with product selection, configurations, and design tools.
Takeaway
VELUX is the go-to name for skylights and roof windows, and they’ve earned that spot by sticking to what they do best. Their combination of global expertise, sustainable practices, and high-quality products makes them hard to beat. If you’re looking for conventional windows or entry doors, though, you’ll need to look elsewhere—they focus strictly on “through the roof” solutions.

3. Vallisco
Vallisco is a project-level window and door manufacturer serving Southeast Asia, Europe, and select global markets. Established in 2024 as a dedicated brand under Qeeka Home, Vallisco draws on over 24 years of accumulated experience in the industry. The brand operates independently, supported by its own manufacturing facility acquired by Qeeka in 2019.
Headquartered in Shanghai, China, Vallisco specializes in bulk and project-based window and door solutions for villas, private residences, hospitality venues, greenhouses, and commercial developments.

For retail customers seeking single replacements, Vallisco may not be suitable—but for multi-unit projects, it is a strong, capable partner.

4. Pella Corporation
When I think of long-standing American craftsmanship, Pella is one of the first names that comes to mind. They’ve been in business since 1925, and they’ve managed to stay at the top without losing their family-owned roots.

For large-scale or commercial projects, there’s no strict MOQ. Everything is scoped out through a project consultation, and pricing, logistics, and order volume are adjusted to fit the job.
Procurement Channels

If you’re looking for the lowest-cost option on the market, though, Pella’s premium lines may not always fit the tightest budgets.

5. YKK AP Inc.
You probably know YKK from their zippers, but in the world of windows and facades, their architectural products division is a serious global heavyweight. Since 1957, YKK AP has been quietly shaping skylines and neighborhoods across continents.
Headquartered in Tokyo, Japan, YKK AP operates in 12 countries and employs over 18,000 people. In 2024 alone, they pulled in roughly $3.8 billion USD in net sales. Their real strength? Full control over everything they make. From raw aluminum to final installation-ready systems, they run the entire process under their “Integrated Production System.”
What sets them apart is their ability to serve two very different worlds at once: high-spec commercial facades and reliable residential vinyl products. And they do both really well.
Headquarter: Tokyo, Japan
Website:https://www.ykkapglobal.com/en
Key Products
- Curtain Wall & Facade Systems: YKK AP offers stick-built and unitized curtain wall systems through its Erie Architectural Products unit. These are perfect for high-rise commercial and institutional buildings.

- ISO 14001 Certified: Their U.S. manufacturing hub in Dublin, GA runs a certified environmental management system. It even recycles 100% of its aluminum waste on-site.

Minimum Order Quantity
If you’re working on a custom facade or large-scale building envelope, YKK AP works by project—not by units. There’s no set MOQ for commercial systems because each job is unique. For residential vinyl products, minimums vary based on local dealer policies. Whether you’re ordering five windows or designing a full tower skin, YKK AP handles procurement with flexibility and consultation at the core.
Procurement Channels
- Commercial Projects: Sold through glazing contractors and commercial building product dealers. YKK AP works closely with architects and specifiers from the early design phase to ensure products are tailored to each job.

Takeaway
YKK AP delivers high-end architectural systems with precision, innovation, and global consistency. Their full control over design, materials, and production makes them a standout in both the commercial and residential space. However, their deep focus on custom, project-based solutions may be more complex for those seeking quick, off-the-shelf ordering.

6. ASSA ABLOY
If you’re in the construction world, chances are you’ve already worked with something made by ASSA ABLOY—even if you didn’t realize it. From the door you walked through this morning to the lock securing your office or the automated entrance at your local hospital, this company has its fingerprints all over the built environment.
Formed in 1994 through a merger of Swedish and Finnish innovators, ASSA ABLOY has grown into a global powerhouse in access solutions. They now operate in over 70 countries, employ more than 63,000 people, and pulled in roughly $14.5 billion USD in 2024.

For a full-blown custom entrance system on a hospital or stadium project, there’s no standard MOQ. Everything is designed and priced around the scope of your project.
Procurement Channels
- Commercial & Industrial: Products are sourced through contract hardware distributors and commercial supply networks. For large jobs, ASSA ABLOY’s specification teams step in with full design support.

Their unmatched range, global footprint, and integration expertise make them the go-to for everything from smart home locks to advanced commercial security systems. That said, navigating their vast brand and product ecosystem can feel overwhelming without a clear project scope or channel.

7. LIXIL Corporation
LIXIL may be a newer name to some, but its roots run deep in Japan’s building industry. Formed in 2011 through the merger of five top-tier Japanese manufacturers, LIXIL was built to be a full-spectrum housing solutions powerhouse—and they’ve done exactly that.
Headquartered in Tokyo, LIXIL now operates in over 150 countries, with a team of around 53,000 people. They’ve built out their global presence by acquiring some of the most recognized names in the business, like American Standard and GROHE.

For builders and developers looking for a one-stop shop for everything from doors and windows to faucets and toilets, LIXIL delivers an unmatched package.

Minimum Order Quantity
LIXIL’s MOQ really depends on where and how you’re buying. For large developers, product orders run through regional sales teams and are handled under project-specific contracts. These are tailored deals involving significant volumes. On the other end of the spectrum, smaller builders or contractors can source LIXIL products through local dealers and distributors.
Procurement Channels
- Large-Scale Projects: For developers and general contractors, LIXIL provides direct sales and project consulting through its Housing Technology business units.
- Dealers and Distributors: Local and regional distributors carry a wide range of LIXIL products, including TOSTEM windows and doors, making them accessible to builders of all sizes.

Takeaway
LIXIL stands out for its total housing solution approach, combining structural building components with water and design tech under one global brand. Their products, especially under the TOSTEM label, are known for durability, thoughtful engineering, and sleek design. However, the complexity of their global structure may make product access or specification support less straightforward outside of Asia.
