1. Andersen Corporation
Andersen has been making windows since 1903. That’s more than a century of experience.
I first worked with them during a hotel renovation. The job needed dependable materials, and Andersen delivered without delay.
They’re known for offering strong window solutions. Their products work well in homes, villas, and guest properties. Their name is trusted, and I’ve seen them used in different regions with consistent quality.

- Location: Bayport, Minnesota, USA
- Phone: 1-800-426-4261
Product Range
- 400 Series Wood Clad
- Fibrex Composite Windows
- A-Series Architect Line
- E-Series Aluminum Clad
- Casement & Gliding Windows
Pricing & Cost Structure
- General Pricing Strategy: Andersen sits in the premium segment. Their prices reflect product quality, performance, and a long history of trusted service.
- Factors Influencing Pricing: Costs change based on window material, size, glazing, and finish. Custom shapes or wood options will raise your total.
- MOQ (Minimum Order Quantity): Orders typically need to meet a minimum project size. Small single-unit requests are not a focus.
- Bulk Order Discounts: Large orders often qualify for price breaks. You can get better deals through authorized distributors or trade programs.
- Payment Terms And Financing Options: Most dealers ask for partial payment upfront. Full payment may be required before delivery unless financing is arranged locally.
Supply Chain & Logistics
- Sourcing And Procurement Process: Andersen uses U.S.-based sources for wood and composite materials. They work with long-term suppliers of consistent quality.
- Raw Material Suppliers And Partnerships: Their supplier relationships are well-established. This helps keep production steady and reliable.
- Warehouse And Distribution Network: They have multiple hubs across the U.S. This supports better inventory flow and helps avoid job site delays.
- Shipping Methods and International Delivery Options: Orders are shipped by freight or truck. International shipping is available, but usually managed through dealer partners.
- Freight and Customs Handling Support: Customs and import help depend on the dealer. Andersen doesn’t directly manage this but works with international agents.
Takeaway Note
If your project calls for trusted performance and reliable support, Andersen is a solid choice for villas, homes, and guest buildings. That said, pricing may not suit tight budgets, and they aren’t ideal for small or low-volume orders. Choose them for stability, not speed or savings.
2. Oknoplast
Oknoplast has been making windows since 1994. I remember learning about them during a villa project in Croatia. The client needed windows that could handle wind and salt air. Oknoplast held up well.
They are based in Poland but supply to many countries across Europe. Their strength lies in PVC windows and accessories. They’re also known for neat finishes and clean designs.
- Website: https://oknoplast.com
- Location: Ochmanów, near Kraków, Poland
- Email: biuro@oknoplast.com.pl
Product Range
- PVC Casement Windows
- Sliding Windows
- Tilt & Turn Windows
- Aluminum Clad Windows
- Roller Shutters
Pricing & Cost Structure
- General Pricing Strategy: Oknoplast sits in the mid-range category. It’s a good balance between cost and durability for mid-size building projects.
- Factors Influencing Pricing: Prices change based on frame material, glass type, insulation level, and opening system. Style choices can also shift cost.
- MOQ (Minimum Order Quantity): Most dealers require orders to meet a small project size. One-unit orders are not standard for this brand.
- Bulk Order Discounts: Larger volume brings price reductions. For hotel or multi-unit housing, better pricing is usually available.
- Payment Terms and Financing Options: Terms vary by country. Most dealers ask for partial payment upfront, with final payment before or at delivery.
Supply Chain & Logistics
- Sourcing and Procurement Process: Oknoplast uses European-sourced PVC and aluminum. Their suppliers meet CE and quality standards for safety and performance.
- Raw Material Suppliers and Partnerships: They partner with VEKA for profiles. This helps keep window strength and consistency across product lines.
- Warehouse and Distribution Network: Warehouses are spread across Europe. Products are delivered through local dealers, making logistics smooth within the region.
- Shipping Methods and International Delivery Options: Shipping is by truck inside Europe. Outside Europe, orders go by freight and require advance planning.
- Freight and Customs Handling Support: Customs support depends on your dealer. Some offer full assistance, while others leave this to the buyer.
Takeaway Note
If you’re sourcing for homes, hotels, or small buildings in Europe, Oknoplast is a strong fit with good flexibility and reliable finishes. However, if your project is outside Europe, logistics can take longer, and local support might be limited.
3. Vallisco
Vallisco is a newer name, but it comes from years of manufacturing experience behind the scenes. I first learned about them during a project in Malaysia. The owner wanted modern frames, fast answers, and solid packaging. Vallisco handled it well from start to finish.
Even though the brand is new, its background in production goes back to 2007. What stands out to me is their direct factory model. You speak with the team behind the product, not layers of middlemen.
- Website: https://vallisco.com
- Location: No. 1926, Cao An Highway, Jiading District, Shanghai, China
- Phone/Email: +86 18502136587 l kelly@vallisco.com
Product Range
- Sliding Windows
- Tilt & Turn Windows
- Fixed Frame Windows
- Glass Curtain Walls
Pricing & Cost Structure
- General Pricing Strategy: Vallisco offers mid-range pricing, making them accessible for bulk projects that want good build quality without going premium.
- Factors Influencing Pricing: Prices vary depending on glass type, aluminum thickness, surface treatment, and order size. Shipping distance also plays a role.
- MOQ (Minimum Order Quantity): Projects must meet minimum order volume. They specialize in multi-unit, not single-window jobs.
- Bulk Order Discounts: Discounts are available for full container or multi-building orders. Savings improve with volume.
- Payment Terms And Financing Options: Most orders follow a split payment plan, typically 50% upfront, 50% before shipment. Custom terms may be offered to long-term buyers.
Supply Chain & Logistics
- Sourcing and Procurement Process: Vallisco controls sourcing through in-house and partner factories. This gives them better tracking and quality at each step.
- Raw Material Suppliers and Partnerships: They work with tested regional suppliers for glass and aluminum. All materials follow international export standards.
- Warehouse and Distribution Network: Products are shipped directly from their China facility. There are no regional hubs yet, so lead times should be confirmed early.
- Shipping Methods and International Delivery Options: They handle sea freight mainly. Air shipping is available for smaller loads, but costs more.
- Freight and Customs Handling Support: Vallisco offers help with paperwork, container booking, and export docs. Import customs are handled by the buyer or local agent.
Takeaway Note
Vallisco is a strong fit if you’re handling new builds or upgrades in Asia or Europe and need full control from a factory partner. That said, because they’re still building brand history, you may not find as many reviews or regional support yet. Give them clear specs and timelines to stay on track.
4. Internorm
Internorm has been around since 1931. I got to know them while sourcing windows for a hotel renovation in Austria. The local team wanted good insulation and low upkeep. Internorm delivered both.
They’re based in Austria but have a strong reach across Europe. Their windows are known for strong thermal performance, modern designs, and solid factory finish.
They’re still family-owned, which I think helps with consistency. Internorm builds their own profiles and glazing, so you’re getting a full system, not mixed parts.
- Website: https://www.internorm.com
- Location: Traun, Austria
- Phone: +43 7229 7700
Product Range
- uPVC Windows
- Timber/Aluminum Composite Windows
- Lift & Slide Doors
- French Doors
- Entrance Doors
Pricing & Cost Structure
- General Pricing Strategy: Internorm prices fall in the mid to premium range. Their focus is on energy savings and long-term value, not short-term savings.
- Factors Influencing Pricing: Pricing changes with material type, frame depth, thermal ratings, and color finishes. Triple-glazing or smart tech will raise the price.
- MOQ (Minimum Order Quantity): Most projects are accepted if they include several units. Single replacements or small orders may be routed through retail dealers.
- Bulk Order Discounts: Discounts apply to full-house or multi-unit projects. Local distributors may offer special pricing for builders or frequent clients.
- Payment Terms And Financing Options: Terms depend on the country and partner. Typically 30–50% deposit, with balance due before final delivery.
Supply Chain & Logistics
- Sourcing And Procurement Process: Internorm controls most production in-house, including frame systems and glass units. This improves quality tracking and delivery times.
- Raw Material Suppliers And Partnerships: Their suppliers are all within Europe. They focus on certified wood, glass, and aluminum partners to meet EU standards.
- Warehouse And Distribution Network: Internorm uses multiple production and warehousing sites across Austria and Germany. This supports fast delivery within the region.
- Shipping Methods And International Delivery Options: Orders are mostly delivered by truck across Europe. Export outside the EU is possible but less common and requires planning.
- Freight And Customs Handling Support: European shipments include full tracking. Export help is offered through local agents; customs prep outside the EU is buyer’s task.
Takeaway Note
Internorm is a good match for homes, villas, or hotels that need energy savings, tight sealing, and sharp design. However, since they’re focused mostly in Europe, international buyers may need to plan ahead for shipping, customs, and local support options.
5. VELUX
I first came across VELUX while working on a villa with attic rooms that needed more light. The builder asked for roof windows that wouldn’t leak or overheat. VELUX was the go-to choice, and it worked out well.
VELUX has been around since 1941. They focus on roof windows, skylights, and daylight systems. Based in Denmark, their products are now used in over 35 countries.
If your project has sloped roofs, loft conversions, or top-floor guest spaces, VELUX should be on your list. Their systems combine airflow, natural light, and long-term weather protection.
- Website: https://www.velux.com
- Location: Hørsholm, Denmark
- Phone: +45 45164000
Product Range
- Roof Windows
- Flat Roof Skylights
- Sun Tunnels
- Blinds and Shutters
- Smart Home Window Systems
Pricing & Cost Structure
- General Pricing Strategy: VELUX is in the premium range. Their windows are engineered for specific uses like roof installation and smart ventilation.
- Factors Influencing Pricing: Costs depend on window size, roof pitch, glazing type, and control system (manual vs. electric). Flashing kits add to the price.
- MOQ (Minimum Order Quantity): No strict MOQ, but best pricing comes with full-roof or multi-room orders. One-off retail orders go through local stores.
- Bulk Order Discounts: Contractors and developers can access discounts through VELUX Pro partners. Better terms apply for recurring clients.
- Payment Terms and Financing Options: Local dealers offer flexible payment. Most orders need 50% upfront, with balance due at pickup or delivery.
Supply Chain & Logistics
- Sourcing and Procurement Process: VELUX designs and manufactures in-house. Materials like treated wood, aluminum, and glass are sourced from European suppliers.
- Raw Material Suppliers and Partnerships: They partner with certified wood and glass suppliers who follow EU regulations on durability and sustainability.
- Warehouse and Distribution Network: Multiple warehouses across Europe support fast delivery. Most dealers also keep basic models in stock for quick jobs.
- Shipping Methods and International Delivery Options: Orders ship by truck or pallet freight in Europe. Overseas shipping is arranged case by case through partner networks.
- Freight and Customs Handling Support: VELUX can help with customs papers for exports. Final import steps are often handled by local agents or the client.
Takeaway Note
VELUX is the right choice if you’re adding natural light to top floors, attics, or sloped roofs. The design is clean, and the performance is solid. That said, since they specialize in roof systems only, they may not suit projects that need full window sets for all areas.
6. VEKA AG
I first heard about VEKA while sourcing window frames for a beachfront hotel. The project called for uPVC profiles that could handle salt air and strong winds. The windows made with VEKA frames held up better than others.
VEKA was founded in 1969 in Germany. But they don’t make complete windows, they make the profiles that many window brands use. You’ll find their components inside finished windows across Europe, Asia, and the Americas.
- Website: https://www.veka.com
- Location: Sendenhorst, Germany
- Email: info@veka.com
Product Range
- uPVC Window Profiles
- Sliding Door Systems
- Shutter Profiles
- Reinforced Frame Sections
- Surface Finishing Systems
Pricing & Cost Structure
- General Pricing Strategy: VEKA falls in the mid to high-end pricing range, depending on the product line and customization level for color or finish.
- Factors Influencing Pricing: Price depends on profile type, thickness, color foil, thermal layers, and order volume. Delivery region also affects the final cost.
- MOQ (Minimum Order Quantity): Orders are typically in bulk, often by the pallet or container. They supply to manufacturers, not individual users.
- Bulk Order Discounts: Price breaks apply to long-term buyers and full container purchases. Custom runs require higher order quantities.
- Payment Terms and Financing Options: Standard terms include an advance deposit with final balance before shipping. Long-term clients may access flexible options through local agents.
Supply Chain & Logistics
- Sourcing and Procurement Process: VEKA sources raw PVC and additives from certified European suppliers. Production happens in controlled, in-house facilities.
- Raw Material Suppliers and Partnerships: They partner with chemical and plastic suppliers across Germany and Western Europe, keeping quality and compliance in check.
- Warehouse and Distribution Network: VEKA has over 20 subsidiaries and production sites worldwide, helping serve regional markets without long wait times.
- Shipping Methods and International Delivery Options: Profiles ship by truck or sea freight depending on region. Overseas orders are arranged through local sales teams.
- Freight and Customs Handling Support: Most exports are handled with full paperwork. VEKA supports international buyers with logistics, but customs clearance is handled locally.
Takeaway Note
VEKA is a smart pick if you or your supplier fabricate windows in-house and need steady access to high-quality uPVC profiles. However, since they don’t sell finished windows, they may not be the right match if you’re looking for pre-assembled units or one-source delivery.
7. Pella Corporation
I first worked with Pella on a countryside inn project in Italy. The client wanted wood windows but also needed strong warranties. We imported Pella’s products through a regional partner. The look and performance impressed the entire team.
Pella was founded in 1925 in Iowa, USA. They’re known for a wide range of window types, wood, fiberglass, and vinyl. Their focus is on energy savings and long product life.
- Website: https://www.pella.com

- Phone: 877-473-5527
Product Range

Pricing & Cost Structure
- General Pricing Strategy: Pella sits in the mid to high-end pricing category. Their pricing reflects material type, finish quality, and design flexibility.
- Factors Influencing Pricing: Prices shift based on frame type, glass strength, finishes, and hardware options. Custom sizing and wood types increase cost.
- MOQ (Minimum Order Quantity): MOQ is project-based. Single-unit orders go through retail channels. Multi-window projects receive better terms.
- Bulk Order Discounts: Volume pricing is available through certified distributors. Builders working on repeat orders can negotiate additional savings.
- Payment Terms and Financing Options: Terms vary by dealer. Standard orders require a deposit, with balance due before delivery. Retail outlets may offer financing.
Supply Chain & Logistics
- Sourcing and Procurement Process: Pella sources wood, fiberglass, and glass locally in the U.S. Their production is vertically integrated for better control.
- Raw Material Suppliers and Partnerships: Most suppliers are based in North America. Pella has long-term partnerships for timber, coatings, and glass components.
- Warehouse and Distribution Network: Products are stored in regional centers and delivered through a wide network of dealers and service partners.
- Shipping Methods and International Delivery Options: Orders ship by road freight within the U.S. International buyers use freight forwarding via distributors or partner exporters.

Takeaway Note
Pella is a great fit if you’re working on mid to high-end residential projects that call for style, variety, and reliable product support. That said, for overseas builds, you’ll need to plan ahead. Export lead times vary, and you’ll rely on regional agents for order coordination.
8. Marvin Windows and Doors
I came across Marvin while managing a project near the coast in southern France. The building needed strong windows to handle wind and salty air. The fiberglass frames from Marvin handled the job better than expected.
Marvin has been in business for over 100 years. They’re a U.S.-based company known for durable, energy-saving window solutions. Their products are made for both standard homes and high-performance buildings.

- Factors Influencing Pricing: Cost depends on frame material, size, finish, impact rating, and glazing level. Extra features like coastal hardware increase prices.

9. Milgard Windows & Doors
I first came across Milgard during a small villa upgrade in California. The builder needed something reliable but not too high-end. Milgard’s vinyl windows hit the mark. They were fast to install, and the finish looked clean.
Milgard started in 1962 and is based in Washington, USA. They’re known for producing vinyl, fiberglass, and aluminum windows that are easy to source and install.
What I like about Milgard is their simple process. They have clear product lines and good warranty coverage, making them a favorite among builders who want fast results.

Pricing & Cost Structure
- General Pricing Strategy: Milgard falls into the mid-range segment. They offer solid performance without the high price tag of premium brands.
- Factors Influencing Pricing: Prices depend on window material, size, frame style, and glass options. Vinyl is more affordable; fiberglass costs more.
- MOQ (Minimum Order Quantity): No strict MOQ, but bulk pricing is best for multi-window projects. One-off replacements go through retailers.
- Bulk Order Discounts: Discounts are available for full-home orders or large builds. Repeat clients may receive better rates through dealer programs.
- Payment Terms and Financing Options: Terms vary. Most dealers require a deposit with final payment on delivery. Retail financing may be available through partner stores.

Milgard is a smart choice for builders looking for affordable, easy-to-install window systems that still meet quality standards for residential use. That said, because they focus on the U.S. market, international access may be limited, and export support is basic.
