On one project I had in China, a hotel owner asked me why the windows didn’t match the quote specs. I had no good answer. The factory had switched models without telling us.
That moment made me change how I picked suppliers.
Now, I work hands-on with window manufacturers, reviewing samples, confirming factory standards, and talking with their sales teams before placing any order.
This guide will show you seven Chinese uPVC window companies that are worth your time. You’ll get the facts with no extra fluff on how they actually perform with business clients.
If you don’t want surprises mid-project, this list will help you stay ahead.
So, let’s get started!

1. Vallisco
Vallisco is a newer name, but the people behind it have over 20 years of experience in the windows and doors business. The brand was officially launched in 2024 as a global-facing division spun out from Qeeka Home, one of China’s well-known interior building material companies. Based in China, Vallisco focuses on business customers like villa builders, hotel owners, and construction teams across Southeast Asia, Europe, and beyond.
From what I’ve seen, Vallisco takes a more modern, service-focused approach compared to other suppliers. They understand what international B2B clients need, clear specs, smooth ordering, and reliable lead times. While Vallisco itself is new, its background gives it a strong base to grow fast in the global market.

Key Takeaways
Oridow fits well if you’re managing villa or hospitality projects that need proven uPVC window products and flexible designs. But if your priority is extremely high monthly volume or deep automation, you may want to explore bigger industrial suppliers.
5. Hihaus Windows and Doors
HiHaus was founded in 2004 and is based in Foshan, Guangdong Province, China. Their factory spans 123,000 m² and includes German and Italian automated production lines. With over 800 employees and an output that serves clients worldwide, they’ve built a strong reputation in both aluminum and uPVC window manufacturing.
One thing I like about HiHaus is how they’ve scaled without losing control of the details. You can expect consistent product quality, even with large repeat orders.

Key Takeaways
HiHaus performs well for projects that need repeat volume, clean aluminum finishes, and structured delivery timelines. But if you’re focused mainly on uPVC windows or need low-volume flexibility, smaller suppliers might offer more personal handling.
6. George Buildings
George Buildings was established in 2006 and is based in Foshan, Guangdong Province, China. They manage a broad portfolio including windows, doors, cabinets, tiles, and more. With showroom support and export experience, they’re suited for full-package material sourcing in villa and hotel projects.
I’ve worked with sourcing teams who prefer fewer vendor touchpoints, and George Buildings fits well into that approach. You get access to uPVC windows along with other building materials, all from one supplier. That kind of setup can help streamline logistics and reduce coordination time for your projects.
