1. International Window Corporation
Website: whttps://www.intlwindow.com/
Location: Illinois, United States
Phone: 800‑477‑4032
International Window Corporation has been around for more than 70 years. They are based in the U.S. and focus on jalousie and other window systems that work well in hot, humid places.
Their windows are often used in villas, guest houses, and small hotels, especially in coastal areas. I’ve seen their products perform well in real projects. They’re built to let air flow through while still keeping rain and heat out. That’s key if you run a property where natural ventilation matters.
The company also understands bulk orders. If you’re replacing many windows at once, they know how to handle it.
Product Line
- Vinyl Jalousie Windows
- Aluminum Jalousie Windows
- Acoustic Vinyl Windows
- StormGuard Series
- Replacement Window Units
Research & Development (R&D)
Their R&D is mainly handled in-house. They test their jalousie systems for strength, airflow, and rust resistance. This helps when the windows are used in areas with salt air or heavy rain.
They focus more on improving what they already make, instead of launching new styles all the time. While this means fewer new designs, it also means their current models are reliable. I’ve noticed that their windows often have the same specs across years, which helps with long-term planning for larger projects.
Sustainability & Ethics
- Material Selection: Uses aluminum and vinyl but doesn’t highlight recycled content or green sourcing practices. Material choice leans toward long-life usage over eco-certification.
- Energy Use: Offers sealed glass systems that help reduce indoor heat, which can lower cooling costs for villas, B&Bs, or guest lodges in warm areas.
- Waste Management: No detailed public data, but simple product design means fewer off-cuts during manufacturing and lower waste during installation.
- Community Support: Jobs stay local within the U.S. factory system. This supports domestic employment and helps avoid long overseas shipping routes.
- Longevity: Their windows are built to last many years. That helps reduce waste from frequent repairs or replacements.
Pricing & Cost Structure
Pricing is mid to upper mid-range. On average, their jalousie window systems cost between $400–$500 per unit. That’s before bulk discounts.
They work well with business buyers. If you’re placing a large order, you can get better pricing and clearer lead times. Their MOQs may apply, but they’re often flexible for projects involving full-house replacements.
Final Verdict
International Window Corporation is a good fit for villas, hotels, and coastal homes needing dependable ventilation windows. Their biggest strength is long-term durability and reliable service.
However, if you’re looking for modern styling or eco-certified materials, their product line might feel a bit behind today’s newer brands.

2. Pella Corporation
Website: https://www.pella.com
Location: Pella, Iowa, United States
Phone: 877‑473‑5527
Pella Corporation has been in business since 1925. They’re one of the largest window and door manufacturers in the U.S., with a strong track record in both residential and commercial supply.
If you’re managing a building project that needs consistent quality, Pella is a name you’ll likely come across. Their jalousie-style systems are part of their wider custom and architectural product lines. I’ve seen them used in boutique hotels, inns, and multi-unit properties across North America.
Their large manufacturing scale means they’re prepared for bulk orders, and they work well with trade clients.
Product Line
- Architect Series Wood & Aluminum-Clad
- Lifestyle Series with Integrated Blinds
- Vinyl Windows with Adjustable Louvers
- Aluminum Jalousie Systems (via custom program)
- Storm-Resistant Windows
Research & Development (R&D)
Pella handles its R&D in-house through a dedicated innovation team. Over the years, they’ve secured more than 150 patents, covering window hardware, frame systems, and energy features.
Their testing process is well-documented. Each product goes through air, water, and structural tests that meet or exceed U.S. performance standards. This adds a layer of trust, especially if your projects are in areas with strong winds or storms.
They also respond quickly to changing building codes and customer needs. Their adjustable systems are often modified to meet regional rules or design preferences, which helps in both urban and rural settings.
Sustainability & Ethics
- Material Selection: Uses FSC-certified wood and high-grade aluminum. This helps reduce environmental impact while meeting long-lasting performance standards.
- Energy Use: Many window systems are Energy Star certified. These help building owners reduce HVAC use and energy bills.
- Waste Management: Has recycling stations at plants. Materials like glass and scrap aluminum are sorted and reused in the production cycle.
- Community Support: Runs workforce programs, charity housing projects, and local engagement through its foundation.
- Longevity: Their windows come with strong warranties. Longer lifespans mean less waste and fewer replacements.
Pricing & Cost Structure
Pella sits in the premium price tier. Their jalousie-compatible systems are priced higher, especially when custom configurations are involved. But in return, you’re getting a well-built product with tested performance and warranty support.
They accept large orders and work through dealer networks or direct sales teams. You’ll also find flexible payment terms, especially if you’re managing multi-unit or long-term projects. Bulk orders often come with pricing adjustments.
Final Verdict
Pella is best for buyers needing durable, U.S.-made window systems with strong warranties and support. You get trusted performance with each order. On the other hand, if you’re after lower-cost or fast-turnaround options, Pella may be slower and more expensive compared to regional suppliers.

3. Vallisco
Website: https://vallisco.com
Location: No. 1926, Cao An Highway, Jiading District, Shanghai, China
Email/Phone: kelly@vallisco.com | +86 18502136587
Vallisco is a fresh name in the door and window industry, but it comes with years of experience behind it. The brand was launched in 2024 by the team behind Qeeka Home, one of China’s top home improvement platforms.
They focus on helping business clients like you, whether you’re building villas, upgrading hotels, or replacing windows across multiple units. Their team supports custom requests, bulk orders, and project-specific guidance. I’ve seen how they manage product samples, provide CAD support, and follow up after delivery.
For Southeast Asia and Europe, they’re positioning themselves as a flexible and service-focused supplier.
Product Line
- Aluminum Jalousie Windows
- Slim-Frame Casement Windows
- Integrated Door & Window Systems
- Tilt & Turn Windows
- Sliding Door Systems
Research & Development (R&D)
Vallisco handles R&D in-house. Their engineers work directly with architects and project managers to fine-tune product specs. This makes their systems easier to adapt for different climates or building codes.
They test samples for wind resistance, waterproofing, and thermal insulation. Their team also checks surface treatments like powder coating or anodizing to make sure the finish holds up over time.
Their product development is shaped by market needs. If you’re working on a project with non-standard sizing or layout, their design team can help develop a matching system.
Sustainability & Ethics
- Material Selection: Uses high-grade aluminum and tempered glass sourced from vetted local suppliers, helping reduce over-transportation and material waste.
- Energy Use: Focuses on insulating frames and multi-layer glazing to reduce building energy use and control interior temperature.
- Waste Management: Manages factory waste internally and follows clean-cutting methods to limit material loss during production.
- Community Support: Works with local labor and vendors in Shanghai, keeping its operations regionally supported.
- Longevity: Offers build-to-last window frames and mechanical systems, reducing how often parts need to be repaired or changed.
Pricing & Cost Structure
Vallisco targets the mid-range market, with pricing that balances quality and flexibility. If you’re sourcing for small hotels, villas, or multi-home upgrades, their rates are competitive.
Minimum order quantities apply, but they’re open to working with phased orders. You can request samples, custom sizes, and bundled shipments. Payment terms are often discussed case-by-case, depending on order size and project stage.
Final Verdict
Vallisco is a great fit for builders and developers needing a responsive, design-friendly supplier in Asia or Europe. Their team is flexible, and their product quality is strong.
That said, as a newer brand, they may still be building up their supply chain and support systems. So timelines or regional reach might not yet match larger global firms.

4. Internorm
Website: https://www.internorm.com
Location: Traun, Upper Austria, Austria
Email/Phone: contact@internorm.com | +43 7229 770
Internorm is one of Europe’s most well-known window brands. The company started in 1931 and is still family-run today. Their focus is on long-lasting, high-performance windows with modern features.
They build everything in Austria, using automated systems and strict quality checks. I’ve worked with teams who used Internorm for upscale hotels, guesthouses, and green-certified villas. Their products are especially good for energy-conscious builds in cold or mixed climates.
If your project needs both airflow and insulation, Internorm’s smart ventilation systems can be a strong option.
Product Line
- UPVC-Aluminum Composite Windows
- Timber-Aluminum Hybrid Windows
- Slim Jalousie-Integrated Systems (I-tec)
- Fixed Glass Facade Elements
- Sliding Systems with Built-in Louvers
Research & Development (R&D)
Internorm runs all its R&D in-house. They have their own testing labs and innovation departments in Austria. That helps them move fast on new technologies and respond to changes in the market.
One of their standout inventions is the I-tec system. It lets you add controlled ventilation, shading, and even solar-powered window blinds, without extra cables or external power. I’ve seen this work well in homes that want to keep a clean look without giving up comfort.
They also use weather chambers and pressure tests to make sure each window system meets high insulation and air-tightness standards.
Sustainability & Ethics
- Material Selection: Uses FSC-certified wood and recyclable aluminum, keeping materials both high-quality and better for the environment.
- Energy Use: Builds energy-saving windows with high insulation ratings, helping reduce heating and cooling costs for long-term owners.
- Waste Management: Recycles all production waste at their factories and uses clean-cutting machines to minimize offcuts.
- Community Support: Offers long-term jobs in Austria and trains workers through local education programs.
- Longevity: Products are tested for decades of use and come with system warranties, cutting down on replacement waste.
Pricing & Cost Structure
Internorm falls into the premium bracket. Their windows cost more upfront, especially if you choose smart features like I-tec ventilation or hybrid wood-aluminum frames.
That said, they’re a strong long-term value. Most clients I’ve worked with see savings in energy use, and less money spent on maintenance or replacements. They support bulk orders and have regional distributors across Europe. Payment terms vary by country.
Final Verdict
Internorm is ideal for hotels, villas, and energy-focused buildings in Europe. Their window systems combine smart design with strong comfort and insulation performance. However, if your budget is tight or your project needs a fast turnaround, their higher prices and longer lead times may be a challenge.

5. VEKA AG
Website: https://www.veka.com
Location: Sendenhorst, North Rhine-Westphalia, Germany
Email/Phone: info@veka.com | +49 2526 29-0
VEKA AG is one of the world’s largest makers of uPVC window and door profiles. They started in 1967 in Germany and now operate in over 40 countries.
They don’t sell complete windows. Instead, they supply high-quality frames and systems that other manufacturers use to build finished units, including jalousie-style setups. If you’re working with a builder or fabricator in Europe or Asia, there’s a good chance their windows are made using VEKA profiles.
I’ve come across VEKA in several mid-size hotel builds where consistent quality and long-term availability were key.
Product Line
- SOFTLINE 76 uPVC Profiles
- SOFTLINE 82 MD Triple-Seal Systems
- Aluminum-Clad uPVC Frame Solutions
- Sliding and Folding Door Profiles
- Jalousie-Compatible Louvred Frame Profiles
Research & Development (R&D)
VEKA manages R&D from its German headquarters. Their team focuses on material strength, thermal performance, and easy installation. They test all profiles for weather resistance, colorfastness, and long-term use.
They’ve also developed specialty welding and joint systems, which help reduce air leaks and make window units easier to assemble. That means fewer problems later during installation.
Because VEKA supplies to other fabricators, their profile systems need to fit a wide range of local building needs. Their engineering teams work with partners to adjust designs for each region.
Sustainability & Ethics
- Material Selection: Uses virgin and recycled uPVC blends. Their materials meet EU safety and performance standards.
- Energy Use: Profile systems are designed to reduce heating and cooling needs through multi-chamber insulation.
- Waste Management: Operates its own recycling plant in Germany, turning old frames into usable raw materials.
- Community Support: Trains local workers and runs family-friendly employment programs at its headquarters.
- Longevity: Profile designs are tested for 40+ years of use, helping reduce early replacements and waste.
Pricing & Cost Structure
As a supplier of profiles, not finished windows, VEKA’s pricing is based on production scale. Their clients are usually factories or large fabricators. If you’re ordering through a local builder, the price you pay will reflect both the frame and the labor used to build the final window.
That said, VEKA profiles fall into the mid-range category. They’re not cheap, but they offer strong long-term value. If you’re planning a large renovation or multi-building project, you can expect steady supply and bulk options from their partners.
Final Verdict
VEKA is a solid choice if your project relies on local fabricators and you want strong, consistent window frame systems. Their quality and recycling practices are well-proven.
Still, since VEKA doesn’t sell finished windows, you’ll need to work through one of their partner builders or suppliers to get jalousie systems assembled.

6. Secco Sistemi
Website: https://www.seccosistemi.com
Location: Preganziol, Treviso, Italy
Email/Phone: info@seccosistemi.com | +39 0422 497700
Secco Sistemi has been creating architectural window and door systems since 1947. Based in northern Italy, they specialize in slim-profile steel, brass, and corten window frames.
They’re not your average window maker. Their designs are used in high-end projects, including hotels, historic buildings, and modern villas. I’ve seen Secco’s systems in both new builds and restoration projects. They offer clean lines, high strength, and fine detail that architects often request.
If you’re managing a project that values both form and function, Secco brings a high-end, crafted approach to jalousie-style and louvered systems.
Product Line
- OS2 Slim Profile Window System
- EBE Thermal-Break Metal Systems
- XT Steel Windows with Integrated Louvers
- SA Louvre Shading and Ventilation Elements

Research & Development (R&D)
Secco’s R&D team blends engineering with design. They’ve created their own patented profile shaping machine called “Alda,” which helps them form clean, thin profiles in tough metals.
They focus on long-term durability and building integration. Their systems are tested for energy efficiency, wind pressure, and air infiltration. I’ve seen them used in both cold and coastal areas, which shows how adaptable their solutions are.
They also work closely with architects to modify or develop systems for specific building codes or design needs. That’s a big plus if you’re planning a custom build or a restoration job.
Sustainability & Ethics
- Material Selection: Uses recyclable metals like brass, steel, and corten, helping reduce waste and support long-lasting building cycles.
- Energy Use: Offers thermal-break designs and insulated glazing that lower the need for indoor heating or cooling.
- Waste Management: Produces in controlled batches with minimal leftover material thanks to in-house shaping tools.
- Community Support: Works with regional suppliers and Italian craftsmen to keep production local and skill-based.
- Longevity: Systems are built for multi-decade use, reducing the need for replacements and lowering total resource use over time.
Pricing & Cost Structure
Secco Sistemi sits firmly in the premium price category. Their products are designed for high-spec projects, so prices reflect the materials and custom fabrication.
If you’re managing a boutique hotel or upscale villa, the cost may be justified by the long-term durability and look. Their systems are sold through select partners or direct architect orders. MOQs are project-based, and custom requests usually involve lead time and design drawings.
Final Verdict
Secco Sistemi is ideal for hotels, villas, or historic projects that need strong design and performance in one system. Their materials are durable and their style stands out. However, due to their premium positioning and made-to-order approach, costs are higher and lead times can be longer than more standard options.

7. Oknoplast
Website: https://www.oknoplast.com
Location: Ochmanów, near Kraków, Poland
Phone: +48 12 278 40 00
Oknoplast is a well-known European window and door manufacturer. Founded in 1994, they’ve grown from a local factory into a major brand serving more than 10 countries across Europe.
They focus on uPVC and aluminum window systems, many of which include options for integrated ventilation, shading, or louvered designs. I’ve worked with builders in Poland and Germany who use Oknoplast for mid-sized hotel upgrades and villa projects. Their strength is offering energy-efficient, modern products at reasonable prices.
Their factory in Ochmanów is fully automated and produces thousands of units each day, so they’re ready to handle large-scale orders.
Product Line
- Prolux uPVC Windows
- Winergetic Premium Passive Windows
- Pixel Slim-Frame Systems
- Aluminum Louvre and Jalousie-Compatible Units
- Roller Shutters and External Blinds
Research & Development (R&D)
Oknoplast runs in-house research and testing. Their engineers focus on thermal performance, frame thickness, and multi-point security systems. Products are tested for water resistance, pressure, and insulation.
They often collaborate with VEKA for their profile systems, which helps keep the frame quality consistent across models. Their team updates window models every few years to reflect new trends or regional needs.
They also conduct glazing tests, including solar control and acoustic performance, which can be useful if your project is in a busy or warm area.
Sustainability & Ethics
- Material Selection: Uses high-quality recyclable uPVC and aluminum; works with VEKA, which follows European eco-standards.
- Energy Use: Offers triple-glazed and passive-house certified options that reduce energy bills and support green building certifications.
- Waste Management: Runs closed-loop production systems and reuses leftover material directly in their factory process.
- Community Support: Trains workers locally and supports Polish manufacturing jobs in their home region.
- Longevity: Windows are rated for 30–40 years with minimal maintenance, making them a good long-term investment.
Pricing & Cost Structure
Oknoplast operates in the mid-range category. Their pricing is often lower than Western European brands but still delivers strong performance and warranty coverage.
If you’re sourcing for multi-unit buildings or guesthouses, you can expect stable pricing and flexible order sizes. Their dealer network helps with quoting, logistics, and on-site support. Minimum order quantities are moderate and suited for business-scale orders.
Final Verdict
Oknoplast is a strong pick for hotels, guesthouses, or villas needing quality windows with energy-saving features at a practical cost. They balance modern design with production speed.
That said, if your project demands highly customized metalwork or smart ventilation features, Oknoplast’s catalog may feel more limited compared to high-end suppliers.

8. Duralco
Website: https://duralcoph.com
Location: Quezon City, Metro Manila, Philippines
Email/Phone:info@duralcoph.com | +63 2 8372 3484
Duralco is one of the oldest aluminum window and door manufacturers in the Philippines. Founded in 1987, the company has grown to serve both residential and commercial projects throughout Metro Manila and nearby provinces.
They offer a wide range of products, but their jalousie window systems are a staple, especially for tropical homes and beachside properties. I’ve worked with clients in Southeast Asia who’ve used Duralco for villas and small hotel upgrades. Their products are simple, functional, and built to handle heat, humidity, and salt air.
Duralco also supports full-service delivery, from design to installation, which can save time if you’re managing a local project.

They test frame strength, glass fitting, and corrosion resistance. Their jalousie frames are built to prevent water entry and offer smooth operation, even in coastal areas. While not high-tech, their process is reliable for everyday use.
They also tweak designs based on client feedback. This helps them stay practical and responsive to local building needs.
Sustainability & Ethics
- Material Selection: Uses locally sourced aluminum and standard glass types to reduce transport emissions and support local suppliers.
- Energy Use: Jalousie systems provide passive cooling, reducing dependence on air conditioning in tropical homes and villas.
- Waste Management: Aluminum cut-offs are sorted and reused; excess glass is handled through local recycling channels.
- Community Support: Employs local teams and supports construction jobs throughout Metro Manila.
- Longevity: Frames are built to resist rust and last through rain, sun, and coastal weather conditions.
Pricing & Cost Structure
Duralco positions itself in the budget to mid-range market. If you’re planning a renovation for a guesthouse or B&B in the Philippines, their pricing is very competitive.
They’re also open to custom sizing, and their team often works directly with contractors. Minimum order quantities are flexible, and bulk orders receive volume discounts. For projects within the region, they offer both supply and installation options.
Final Verdict
Duralco is best suited for tropical projects in Southeast Asia, especially villas, beach houses, or inns that need simple, weather-ready windows. They offer dependable quality at a good price.
However, for larger-scale international projects or high-spec builds, their systems may lack the advanced design features found in more export-focused brands.

Ping An is a locally operated window and door supplier based in Metro Manila. They’ve been serving residential and light commercial projects for several years. While they’re smaller than other names on this list, they have a steady following among contractors and small hotel owners in the Philippines.
Their jalousie systems are made for tropical use. I’ve seen them in budget inns, B&Bs, and multi-room villas. If your project is based in the Philippines and needs quick turnaround or flexible orders, Ping An is worth considering.
They also provide installation and on-site measurement, which can simplify your planning process.

They follow proven window construction methods, focusing on durability and airflow. While their jalousie products aren’t built for extreme climates, they do hold up well in tropical weather. Their simple build process also makes repairs and part replacements easier.
They’re best at meeting straightforward project needs where function and fast service matter more than new technology.
Sustainability & Ethics
- Material Selection: Uses standard aluminum and local glass sources to keep costs low and support regional suppliers.

They’re flexible with minimum order quantities. You can place smaller bulk orders or phased purchases depending on the size of your renovation or build. Payment terms are simple and handled locally, which works well for nearby builders or site managers.
Final Verdict
Ping An is best for local projects in the Philippines that need fast, affordable jalousie window systems. Their pricing and service flexibility make them ideal for B&Bs and modest villa builds.
