Many homeowners buy windows and doors in a foreign country, you concern about aesthetic, cost, performance and shipping. You probably don’t know the industry terms, term of technology, such as U- value, or warm edge spacer. So I would like to introduce them to you in a more general broad way, so as to help you have a better understanding of our products.
Firstly, is aesthetic. Good looking or aesthetic is important for windows, that’s the first vision for audience. We have newly designed a slim modern window which is a perfect match for modern homes. The slim modern windows use an exclusive ultra-narrow frame which is 35% slimmer than regular frame to minimize the borders for a maximized view. A slim frame deserves a slim handle. Our escutcheon-free handle is different from the average handles. With the hidden escutcheon, your windows add more modern elements to your home. European SOBINCO concealed hinge creates a streamlined look for modern homes.
What’s more, window and sash are roughly equal onsame level while the sash are usually higher than frame in most of the windows.

The Sobinco products are exported to 60 countries in 5 continents. The visual difference between opening windows and fixed windows will be minimal and this contributing to the total aesthetic of your interior.)
We offer our customers diversified color options for profiles, so it could perfectly match the color of handle, window frame and sash, even some rare colors like metallic and pearl color.

It gives customers more choice, offering an impressive selection of chemistries and a wide range of colors and finishes for all your powder coating needs.)


Secondly is cost. As we have exported a lot of windows and doors to US for long time, we have better understanding of local windows/doors market. Familiar with the local building codes and climates, we offer various solutions to meet your budget.
(According to your project location, we design the window specification for your project based on the local building codes, climates and your preference. You get what you exactly need from us.)
Not just the best performance that we can offer you. The top performance usually comes with a higher price, which might be not always necessary for your specific project. What we try to design is a suitable solution, not a most expensive one. With the same quality and performance, our production cost is comparatively 60% lower than local companies in America.
Meanwhile, we produce our windows with a nailing fin or flange to provide easy installation, to save more potential installation cost. The longer the project takes, it means more money is losing. Besides easy installation, we use 4 layers packing system to make sure our products arrive to their final destinations in time without any damage, so it won’t delay the project schedule.
We have three own factories, so we can offer direct sales to our customers with transparent pricing, reducing the expense of “Middleman”. We cut out middleman and pass the saving directly to you.
We are truly custom-made, no additional costs for “Custom” design. You are aware how your money is spent worthy.
Thirdly is about performance. Performance plays an essential role in functions. Belgium Origin Brand SOBINCO multi-point locks have fewer components, with each component capable of sustaining 400lbs for high security and longevity. Its concealed hinges provide excellent strength, durability and great soundproof. To put this in perspective, a window that is opened and closed 10 times a day should last at least 100 years before failure.

The Sobinco products are exported to 60 countries in 5 continents. The hinges have a inventive, secure turn movement. The hinges have an anti-finger trap function.
