If there’s one brand in the window world that practically everyone’s heard of, it’s Andersen.
And not without reason. With over 100 years under its belt, this company has shaped how professionals source, spec, and install windows across North America.
What started as a small lumber business back in 1903 has grown into a $3 billion giant in the window and door industry.
It’s still privately held, which tells you a lot about the long-term thinking and stability behind its operations.
Andersen isn’t just a name on a label. It’s a partner that construction teams, architects, and large-scale developers keep coming back to—because it consistently delivers.
Key Products
- Architectural Collection (E-Series & A-Series): If you’re designing a showpiece, these lines bring the freedom to choose custom colors, exotic woods, and precision shapes. E-Series is all about custom aesthetics, while A-Series zeroes in on energy performance without skimping on design.
- 400 Series: This is the go-to for builders who need that sweet spot between function and flair. It’s Andersen’s most popular line for good reason—it simply works across tons of applications.
- 200 Series: When you want the warmth of wood but need to stay on budget, this line gives you tried-and-true styles in common sizes. It’s especially helpful on fast-moving multi-unit residential jobs.
- 100 Series (Fibrex®): Built from Andersen’s exclusive composite material, this line takes sustainability and strength seriously. It’s a vinyl alternative that doesn’t feel like a compromise.
- Renewal by Andersen®: A whole different beast—this is their full-service division for direct-to-homeowner replacements. Everything from consult to install is handled in-house, and the Fibrex® material is the star of the show here too.
Clientele and Global Footprint
Andersen doesn’t cater to one kind of buyer, they’ve built an ecosystem for both sides of the industry. Whether you’re a builder managing hundreds of window units across a development or a homeowner replacing ten windows in a renovation, they have a path tailored to that journey.
Most of their strength lies in North America, but they’ve also planted roots in Canada and Italy with manufacturing operations and distribution support. Their footprint is strategic—not scattered—and it allows them to keep logistics sharp and lead times manageable.
Services & Client Support
- Certified Contractor Network: Andersen partners with trained professionals, so you’re not guessing when it comes to installation quality. They vet the contractors, so you don’t have to.
- Full-Service Replacement (Renewal by Andersen): If you’re targeting the consumer replacement market, this division handles it all—from measurements to final walk-throughs—with in-house teams.
- Design Tools and Resources: Visualizers, style quizzes, and spec tools make pre-construction planning smoother. No more back-and-forth over vague dimensions or misunderstood finishes.
- Strong Warranty Support: The transferable “Owner-to-Owner” warranty builds confidence for resale and covers 20 years on glass, 10 years on non-glass components. That’s rare air in this industry.
- Pro Resources: Trade professionals can access installation guides, BIM content, code compliance data, and performance ratings all in one place.
Bottom Line
Andersen delivers the trifecta: trust, performance, and a product range that covers both economy and luxury projects. Their Fibrex® innovation and client service ecosystem make them a solid pick for high-stakes commercial or residential jobs. The only downside? With their popularity and scale, lead times can occasionally stretch in high-demand seasons.

2. JELD-WEN

- Address: 2645 Silver Crescent Drive, Charlotte, North Carolina, 28273, USA

- Customer Care/Warranty: 1-888-JWHelpU (1-888-594-3578)
JELD-WEN has one of those stories that quietly commands respect. It didn’t start flashy.
In 1960, a small team led by Richard Wendt took over a little millwork plant in Oregon. From that modest beginning, it evolved into one of the biggest names in the global window and door market.
Today, the company operates across 14 countries with a team of 16,000 employees—backed by nearly $4 billion in revenue.
That’s not just scale. That’s momentum.
They’ve expanded steadily, not just through organic growth, but by acquiring smart brands that filled gaps and added value, like LaCantina and Domoferm.
From its NYSE listing to its strategic international footprint, JELD-WEN has earned its spot in nearly every procurement short list. And once you dig into what they offer, it’s easy to see why.
Key Products
- JELD-WEN® (Flagship Brand): This is the backbone of their global offerings—versatile, reliable, and built to serve a wide range of price points and project types. You’ll find everything from interior doors to energy-efficient windows.
- LaCantina® Doors: These are for those bold, high-visibility spaces. Folding, sliding, or swinging—this premium brand is about fluid transitions between indoors and out. If your client values wow-factor, this is a go-to.
- VPI™ Quality Windows: Perfect for multifamily and mid-rise commercial buildings. Their focus on vinyl makes them cost-effective, but they don’t cut corners on durability.
- Swedoor® and DANA® (European Brands): For businesses operating in or sourcing from Europe, these brands bring precision and modern design sensibilities to the table. Strong, clean aesthetics with a focus on performance.
- AuraLast® and Auraline® Tech Lines: These aren’t just marketing labels—they’re innovations. AuraLast® protects wood from rot and pests, while Auraline® offers a strong, sustainable composite material that doesn’t warp or swell like vinyl.
Clientele and Global Footprint
JELD-WEN casts a wide net, and that’s good news for businesses. They work across both residential and commercial spaces, whether it’s new builds or retrofits. Developers, architects, distributors, and contractors are all within their service ecosystem. Their reach goes far beyond the U.S. too.
With operations across Europe and North America, they’re not just shipping internationally, they’re building and serving from within those regions. That kind of presence smooths out supply chain hiccups and offers regional customization where needed.
Services & Client Support
- Technical Documentation for Pros: Everything from sizing guides to finishing instructions is available online. If you need specs fast for a bid or install plan, they’ve got your back.
- Warranty Coverage with Detail: Not all warranties are created equal. JELD-WEN spells theirs out clearly, with lifetime coverage on key products like AuraLast® pine and vinyl windows. You won’t be left guessing.
- Dealer and Distributor Network: While they don’t offer direct installs, their network of pros is robust. You’ll find a qualified team in most regions—ready to help with fulfillment and support.
- Customizable Options Across Product Lines: Their multi-brand model gives your team flexibility to spec the right product for different market tiers—without sacrificing brand familiarity.
- Sustainability and Safety Certifications: ENERGY STAR® leadership, UL certifications, and green building contributions aren’t just badges. They’re integrated into the company’s value prop.
Bottom Line
JELD-WEN offers businesses an impressive balance of product variety, regional support, and innovation-driven performance. Their global footprint gives them an edge when scale matters. But if you’re looking for full-service, in-house installation—they leave that to partners, not their own teams.

3. Vallisco
Company Snapshot
- Address: Building 1, No. 1926, Cao An Highway, Jiading District, Shanghai, China 201824
- Website:https://vallisco.com
Vallisco may have been established as an independent brand in 2024, but its roots run deep.
Backed by Qeeka Home, an established name in home improvement since 2007, Vallisco builds on over two decades of expertise in window and door manufacturing.
What sets Vallisco apart is its clear focus on projects that matter. The company isn’t chasing one-off consumer orders. Instead, it works closely with property owners and project teams involved in full-home or hospitality builds.
Whether it’s a boutique hotel, a seaside villa, or a modern B&B renovation, Vallisco is built to serve real architectural needs—not just sell catalog items.
For businesses and homeowners seeking complete, well-supported window and door packages, Vallisco brings experience, scale, and smart service to the table.
Key Products

- Project-Based Customization: Whether it’s a full set for a boutique inn or tailored fenestration for a villa complex, Vallisco works off actual project drawings—not just SKUs.
Clientele and Global Footprint
Vallisco serves a defined, professional client base. Its customers include homeowners with multi-unit replacement needs, architects designing private residences, and project teams managing hotels, B&Bs, and hospitality properties.
Their strongest markets are in Southeast Asia and Europe, where demand for aesthetic yet durable fenestration solutions continues to grow. However, the company remains globally flexible, welcoming inquiries from other regions as long as the project scope aligns.
Vallisco’s approach is tailored, not transactional. That makes them a strong fit for property developers, builders, and homeowners with full-home plans, not one-off, piecemeal replacements.
Services & Client Support
- Project-Based Consultation: Vallisco offers direct support from inquiry to delivery, reviewing blueprints and offering product recommendations based on the project’s climate, style, and structural needs.
- Flexible Volume Fulfillment: Whether outfitting a 10-room villa or replacing all windows in a large house, Vallisco is equipped to handle medium-scale orders with consistency and care.
- Multi-Market Export Experience: The company has deep experience shipping to Southeast Asia and Europe, with logistics, packaging, and support systems already in place.
- Custom Design Compatibility: Need something tailored to your design vision? Vallisco is open to matching specific requirements—including hardware styles, finishes, and configurations.
- End-to-End Coordination: From material selection to final shipping documents, the team supports clients through every key phase—reducing stress on the builder or property owner.
Bottom Line
Vallisco is built for serious projects that need more than just off-the-shelf solutions. With decades of experience, global supply capabilities, and a sharp eye for design flexibility, the company delivers doors and windows that support the real-world demands of custom homes and hospitality properties. However, their premium, project-focused approach may not suit budget or volume-driven buyers.

4. VELUX

When a company’s mission is to bring natural light indoors, you can expect a different kind of energy behind its products. That’s exactly the case with VELUX. Born from a school renovation idea more than 80 years ago, this Danish company now leads the world in roof windows and skylights.
VELUX isn’t trying to be everything to everyone, and that’s its strength. The focus is tight: roof-integrated daylighting and ventilation. And they’ve become the global authority on it.
With operations in over 40 countries, VELUX products are seen not just as windows—but as wellness solutions for healthier indoor spaces.
What keeps them ahead is their blend of elegant engineering and high-performance automation.
Whether it’s a residential skylight that opens when CO₂ levels rise or a roof window that becomes a balcony, every product is thoughtful, smart, and user-focused.
Key Products
- Solar-Powered & Electric “Fresh Air” Skylights: Ideal for smart homes, these units open on their own and close automatically when it rains. They’re intuitive, easy to use, and seriously elevate indoor comfort.
- Manual “Fresh Air” Skylights: A cost-effective option for spaces where the window is within reach. Still brings in all the daylight, just with a manual touch.
- Fixed Skylights: No opening function—just clean, bright light streaming into the room. These are perfect for low-traffic or moisture-sensitive spaces.
- Roof Windows (Top-Hinged & Center-Pivot): Designed for lofts, attics, and upper-floor rooms. They offer ventilation, panoramic views, and meet code for emergency escape where needed.
- Sun Tunnel® Skylights: These clever systems funnel daylight into windowless rooms like closets or hallways. The installation is fast, and the effect is surprisingly powerful.
- Commercial Modular Skylights: Built for large buildings, these systems bring in natural light, boost ventilation, and even support smoke/heat exhaust features for safety compliance.
Clientele and Global Footprint
VELUX works with everyone from custom home builders to large-scale commercial developers. Homeowners, remodelers, architects, and engineers all make up its core audience, and the consistent thread is their interest in natural light, indoor air quality, and long-term sustainability.
While based in Denmark, VELUX is truly global. You’ll find their products in over 40 countries, with regional variants to suit climate and building code differences. Their U.S. division alone is robust enough to serve coast-to-coast markets with tailored solutions. This isn’t a brand you need to explain to clients, it’s often one they already know and trust.
Services & Client Support
- Virtual Design Consultations: Homeowners or pros can book free sessions with VELUX advisors to plan out their skylight project. Super helpful during the pre-build stage.
- Certified Installer Network: Finding a trained installer is easy with their online locator. VELUX doesn’t cut corners—installers are vetted and supported.
- Digital Tools for Pros: Architects and designers get access to BIM files, CAD resources, and a Daylight Visualizer tool to model how light behaves in a space.
- Strong Warranty Backing: Their U.S. skylights come with a 10-year “No Leak” warranty—even if someone else installs it. There’s also up to 20-year coverage on glass and a 10-year hail warranty for impact-rated models.
- Sustainability Resources: VELUX partners with low-carbon suppliers and uses 99% certified wood. Their documentation supports green building efforts and LEED contributions.
Bottom Line
VELUX brings daylight, fresh air, and smart climate control into spaces in a way that feels seamless and well-considered. For architects and builders focused on wellness and energy performance, it’s an obvious partner. However, their tight product focus means they’re not a one-stop shop for standard vertical windows or doors.

Despite its size, Pella remains family-owned, which keeps the company grounded in craftsmanship and long-term thinking.
With more than 10,000 employees, 18 manufacturing sites, and over 200 showrooms across the U.S., it has built a national presence without losing its Midwestern roots.
But what really sets Pella apart is its forward-thinking approach to design and usability. From integrated blinds to hands-free hardware, this brand constantly asks: “How can we make windows and doors better?” It’s no surprise they hold over 150 patents.

Clientele and Global Footprint
Pella is deeply rooted in North America, and that’s where its strength lies. It supports everyone from individual homeowners replacing three windows, to developers outfitting a hundred-unit complex.
Their client list reads like a cross-section of the building industry: architects specifying high-end wood lines, contractors relying on vinyl workhorses, and commercial teams choosing fiberglass for long-term value.
While their focus is regional, their impact is far-reaching. Pella products can be found in everything from modern suburban homes to historic downtown restorations.

Pella brings together innovation, craftsmanship, and trust—making it a top-tier option for professionals who want reliable, design-forward products.

YKK AP balances a wide reach with a targeted approach. Their client base spans homebuilders, glazing contractors, architects, and large-scale developers. On the commercial side, they’ve earned respect for their curtain walls and facade systems. On the residential end, their vinyl and aluminum products offer reliable performance at scale.
They operate across 12 countries and regions, but they don’t take a cookie-cutter approach. Local offices in the U.S., Asia, and beyond are empowered to adapt and support projects based on regional codes, climate, and construction styles.

Tucked up near the Canadian border in Warroad, Minnesota, Marvin’s story starts over a hundred years ago with a family lumber business. That kind of origin gives it a grounding that still shows today, in how they build, how they serve, and how they innovate.
What makes Marvin unique is that they don’t build to stock. They build to spec.
Every order starts fresh, based on the exact needs of the architect or builder. That mindset—”Built Around You®”—has earned them a reputation for being one of the most detail-oriented, customization-friendly window and door makers in the market.

Most of Marvin’s business is focused in North America, supported by a strong network of local dealers. But they’ve also quietly expanded through select international partnerships—mainly where design quality is non-negotiable.
They’re not trying to be everywhere. But where they do operate, they show up with substance.
Services & Client Support

Bottom Line
