The bifold window is a fancy choice in fenestration systems right now. Bifold windows are a type of window that folds, sliding and stacking concertina style, leaving a clear opening. They work in the same way as bifold doors. They combine the practicality of a standard window with the style and elegance of bifold doors, making window holes the perfect opening size as the door. Yet they have fast become a popular feature with self-builders and renovators searching for window styles that are both modern and traditional. Compared to traditional window opening methods, bifold is far superior in terms of opening size and energy efficiency.
That's where Doorwin aluminum bifold windows come in. We've got you covered with a wide range of styles and sizes, the configuration can be split down the middle or left and right, and opened inwards or outwards, so you can choose exactly what you need for your home or business. So whether you're after wide-opening spaces, unobstructed views, or a stylish and functional ultra-large opening window-we have what you need!
Project Cases No. 1
We know that you're looking for something that stands out from the crowd. You want a window that is not only secure, versatile, and chic-you want one that can be opened to the full width of the opening.
The first one is located in the Caribbean Sea region, bifold windows used in this project can give you a totally refreshing idea. Rather than bifold windows, it is more like bifold doors. The client's unique requirement was to install large, fully openable windows on the second-floor balcony of the villa. Bedroom, study, and recreation room, are all fitted with these ultra-large bifolds.
Because of the direction facing the sea, such large bifolds are used at all openings on the second floor, although there is no access to the outdoor space. The owner of the house has installed a transparent glass fence under the openings to ensure personal safety.
These large opening sashes give great freedom to customize window and door systems for houses in these areas with better environmental conditions. The panoramic opening, without any door columns blocking the view, brings a lot of fresh air inside at any time, and you can't help but be excited about these feelings of zero contact with nature just by thinking about it.

01 / Profiles & Energy Efficiency
Doorwin applies the best thermal break aluminum for ultra-large bifolds, not matter window or door. Thermal break aluminum is a material that applies a polyamide bar (PA66 Nylon) between the interior and exterior aluminum to stop heat transmission, also known as thermally broken aluminum. The polyamide bar is usually non-metal. The polyamide we use is from the world-famous brand Technoform Bautec™. Thermal breaks have decreased aluminum frame U-factors (heat loss rate) from roughly 2.0 to about 1.0 Btu/hr-sq. In hot climates. Our thermal break aluminum is more than 1.4 mm in thickness, which is much thicker and stronger than most companies.
Our energy-efficient integrated glazing units (IGU) are designed to follow NFRC standards and meet US Energy Star ratings. These units feature double or triple pane, warm edge spacers, argon gas fill, and Low-E coatings. They will keep your indoor environment comfortable while also saving you money on your electricity and heating bills, saving you up to 300 USD a month depending on the size of your property.
02 / Hardware
European bifold hardware is a highly integrated system with an open and modular concept that allows for simplified production and maintenance, maximum material and energy efficiency, and a high degree of part compatibility. The right hardware will make a positive difference in appearance and performance.
Doorwin uses world-famous hardware brand Savio multi-point locks, hinges, and handles on bifold systems. With the highest quality hinges, thresholds, and rails on our windows and doors, they have been designed to allow both sides of the door to be opened without compromising the interiors. Certified top-class quality exhaustively tested in line with the strictest of guidelines and quality requirements. At the same time, creativity is another significant added value in products that have the functions of aesthetic comfort, easy assembly, modularity, and sustainability at the same time.
Doorwin's professional packing system guarantees all products are delivered safely and without any damage. We apply a four-point packing system. Firstly, adhesive plastic film is applied on interior wood frames and exterior aluminum frames to avoid scratches on the surface. Then, a paper board is applied after we apply air bubble film surrounding the whole windows/ doors to avoid any destruction or clash. Lastly, we place them into a durable non-fumigation plywood crate to avoid any possible damage during transportation.
With years of experience shipping our products worldwide, we could guarantee to ship our products to their final destinations intact and without any damage.
