1. Andersen Corporation
Website: www.andersenwindows.com
Location: Bayport, Minnesota, USA
Andersen has been making windows for over 120 years. That’s a long time, and it shows in how they run their business.
They work with builders, hotel groups, developers, and even villa contractors. I’ve seen many large projects use Andersen windows when timelines matter and product quality has to be consistent.
They’re based in the U.S., but they also ship internationally. You can choose from many product types, and they’ve got a solid record of on-time delivery.
Product Range
- Wood-Clad Windows
- Fiberglass Composite Windows
- Vinyl Windows
- Custom Bay and Bow Windows
- Patio and Sliding Doors
Packaging & Labeling
Andersen handles packaging in-house at most of their factories. Each window is wrapped in protective film and placed in durable crates. For overseas shipping, they reinforce corners and use thick padding.
They also offer project-specific packaging. If you’re buying in bulk for hotels or apartments, they can label boxes with unit numbers or floor levels. That really helps keep things organized on-site.
They’ve started shifting to greener materials too, cardboard with recycled content and foam alternatives. It’s simple, clear, and protective.
Customer Support & After‑Sales
- Multiple Channels: You can reach them by phone, online form, or talk to local dealers. It’s easy to get a hold of someone.
- Warranty Help: Their service team explains warranties clearly. You don’t have to guess what’s covered.
- Project Support: Larger jobs can get assigned a rep. That person sticks with you until the project is done.
- Issue Handling: If anything arrives broken or missing, they respond fast. I’ve seen them fix things in a few days.
- Learning Tools: They offer training videos, printed guides, and walkthroughs. Your team can get up to speed quickly.
Final Thoughts
Andersen is a strong choice for projects that need reliable service, clear timelines, and long-lasting products. It’s a brand many builders trust. However, keep in mind their pricing is on the higher end. If your project has a tight budget, this could be something to consider.
2. Pella Corporation
Website: www.pella.com
Location: Pella, Iowa, USA
Pella has been around since 1925. That’s a long time to learn what customers need. I’ve worked with teams who rely on Pella for both small and large builds.
They’re known for a wide selection of window materials. Many customers choose Pella when they want energy savings and smart designs. Their products are easy to find in stores across the U.S., but they also ship internationally through partners.
Product Range
- Wood Windows
- Fiberglass Windows
- Vinyl Windows
- Smart Windows with Integrated Sensors
- Sliding and Hinged Patio Doors
Packaging & Labeling
Pella mostly handles its own packaging. Their windows come boxed with foam corner protection and shrink-wrap to keep everything safe. For export, they work with freight partners who help reinforce packaging for long travel.
You can request labeled packaging for multi-unit projects. That includes room numbers, project codes, or delivery groups. Their labeling meets U.S. and international shipping standards.
Some packaging has been upgraded to use less plastic. They’re moving toward better materials, especially for eco-conscious clients.
Customer Support & After‑Sales
- Support Channels: You can talk to them by phone, email, or in-store. There’s always a contact point nearby.

Final Thoughts
Pella is a dependable brand that blends good design with energy performance. You’ll find their windows in many commercial builds. That said, lead times can vary by product and location, so plan ahead, especially for large or custom orders.
3. Vallisco
Website: https://vallisco.com/
Location: No. 1926, Cao An Highway, Jiading District, Shanghai, China
Vallisco is a newer name, but their team has been in the door and window business for years. I’ve seen them work closely with project owners, especially across Southeast Asia and Europe.
They focus on full-house window and door systems. Their team understands the flow of a large build, from early design to site delivery. That makes them easy to work with if you’re managing villas, boutique hotels, or home upgrades.
Their factory handles everything in-house. That means better control over quality, pricing, and timelines. I’ve had clients say they liked how clear and simple the whole process was.
Product Range
- Slim Sliding Windows
- Floor-to-Ceiling Window Walls
- Double-Glazed Glass Systems
- Thermal Break Casement Windows
- Pivot and Folding Door Sets
Packaging & Labeling
Vallisco handles packaging at their own facility. Each product is wrapped in foam sheets, sealed with corner guards, and placed in export-rated wood crates.
If you’re ordering in bulk, they can mark each package by room number or section. This is helpful when you’re managing a multi-unit project. They also offer logo printing and custom branding on request.
Their packing uses recycled wood and avoids plastic when possible. It’s neat, safe, and meets shipping rules in Europe and Southeast Asia.

- After-Care: Their team checks in after delivery and follows up during your installation phase.
Final Thoughts
Vallisco is a solid option if you want factory-direct pricing with full project support. Their setup works well for villa upgrades or hotel builds. However, since they’re a newer brand, you might not find many reviews or long-term case studies yet. So, early orders may need closer coordination.
4. Alside
Website: www.alside.com
Location: Cuyahoga Falls, Ohio, USA
Alside has been serving builders and contractors since 1947. They focus on vinyl-based systems and supply across the U.S. I’ve worked with housing developers and remodel teams who like Alside for reliable stock and fair pricing.
They’re especially strong in residential markets. But if your project involves a group of homes, villas, or rental units, Alside can be a solid partner.
Their windows are easy to install, low maintenance, and cost-friendly. If you need to control material costs while keeping timelines tight, this brand could help.
Product Range
- Vinyl Replacement Windows
- New Construction Windows
- Sliding Glass Doors
- Bay and Bow Windows
- Casement and Awning Windows
Packaging & Labeling
Alside works with in-house and logistics partners to package windows for national delivery. Products arrive in padded cartons or bundled frames, depending on size.
For larger jobs, they offer grouped shipments by model or size. Each unit comes labeled, and project-level identification can be requested. Packaging is simple but functional for on-site sorting.
They’ve been moving toward better recycling standards in packaging, which is good for cleanup and disposal.
Customer Support & After‑Sales
- Direct Support: Phone and email support from headquarters and local dealers. Fast help for standard service needs.

Final Thoughts
Alside is a smart choice for mid-size projects focused on cost and consistency. They shine in residential builds and vinyl-based systems. However, for high-end or custom designs, their product line may feel limited—so review your spec needs first.
5. Marvin Windows
Website: www.marvin.com
Location: Warroad, Minnesota, USA
Marvin started over 100 years ago in a small town. Now, they serve projects across North America and beyond. I’ve had clients who pick Marvin when design matters just as much as performance.
Their products feel more premium. That makes them a good fit for luxury villas, resorts, or any project where the windows are part of the visual story.
They focus a lot on energy efficiency and build durability. You can tell they’ve thought through the details. But they still keep support straightforward and easy to work with.
Product Range

For project deliveries, Marvin offers labeled packaging. You can ask for zone tags or unit numbers to help sort by floor or room. Their export packaging meets both U.S. and international shipping rules.
They’ve been switching to greener materials too. Expect more cardboard, less plastic, and cleaner pallets.

6. Milgard Windows
Website: www.milgard.com
Location: Tacoma, Washington, USA
Milgard has been making windows since 1958. They’ve built a strong name on the U.S. West Coast and continues to grow. I’ve worked with customers who like Milgard for their simplicity, availability, and price stability.
They own their production process, from glass to the frames. That makes their delivery times reliable, especially for projects in the western U.S. or Mexico.
For hotels, multi-unit homes, or villa projects that need solid performance but don’t need high-end finishes, Milgard hits a good balance.
Product Range
- Vinyl Windows
- Fiberglass Windows
- Aluminum Windows

Packaging & Labeling
Milgard uses in-house packing for most orders. Their process includes foam padding, shrink-wrap, and corner protection. For larger shipments, they use heavy-duty wrap and wood base crating.
If you’re buying for a building with many rooms, they can group and label items for easier unloading. Their packaging follows U.S. standards, and they include handling instructions and tags.
While their default packaging is basic, it gets the job done. Some options are available for projects needing more labeling or customization.

Final Thoughts

7. Oknoplast
Website: www.oknoplast.com
Location: Ochmanów, near Kraków, Poland
Oknoplast started in 1994 and has grown into one of the top window brands in Europe. I’ve spoken with builders who like their clean look and reliable product range.
Their factory is in Poland, but they export widely, serving over 20 countries. That makes them a good fit if your projects are in Europe or nearby. They focus on PVC and aluminum windows, which are cost-effective and easy to maintain.
For hotels, greenhouses, or housing upgrades in Europe, Oknoplast brings modern styling without making things too complicated.

8. Internorm
Website: www.internorm.com
Location: Traun, Upper Austria
Internorm has been building high-performance windows since 1931. They are one of the leading European brands for composite and energy-efficient window systems.
I’ve worked with design teams who choose Internorm for villas and boutique hotels that want top-quality finishes. Their products are made in Austria but available across much of Europe.
They offer a mix of classic wood, aluminum, and PVC, giving you flexibility based on design and climate. If you’re building in colder regions or aiming for top insulation, they’re worth looking at.
Product Range

Internorm is a strong pick for luxury or energy-efficient builds in Europe. Their composite windows look great and perform well. However, because they focus on premium markets, pricing may be higher than basic PVC brands. Planning early helps avoid long lead times.
9. VELUX
Website: www.velux.com
Location: Hørsholm, Denmark
VELUX has been building roof windows and skylights since 1941. They’re one of the most trusted names for daylight and ventilation solutions. I’ve worked with hotel and villa clients who use VELUX to add natural light in hard-to-reach places.
