Our bi fold doors offer numerous advantages
Advantages of folding sliding glass doors compared to other doors and windows
• Compared to sliding doors (lift-and-slide doors) or French windows, folding sliding glass doors offer a high degree of flexibility.
• The entire door front can be fully opened to let in plenty of air and sunlight.
• You save on heating and energy costs when a lot of natural light enters the interior.
• The interior area can be connected to the garden, balcony or terrace without any obstacles via a flat threshold.
• Even large wall openings can be easily glazed with bifold patio doors, as the individual elements have their own frame.
• Thanks to the stable construction and the latest technology, refined door views and narrow overall depths can be achieved.
• The bifold door hinges can be pushed together to form very small dimensions, so space is saved even with large opening widths.
• Folding patio doors open and close easily and silently in just a few steps.
• Different opening directions are possible: to the right and/or to the left and inwards or outwards.
• Safe, noiseless and easy to use.
• Customizable by choosing different window materials, glass, colors, accessories, etc.
• Because bifold sliding doors consist of many components, they are more stable and secure against break-ins than other door systems that have only one large glass area.
Bi-fold doors for enhanced vision
Since each glass surface element of a bifolding door is built into its own frame, bifold glass doors can cover extremely large areas.
Sliding doors with only one pane of glass as infill, on the other hand, reach their static limits at certain levels.
Exterior bifold doors therefore allow a high degree of transparency and bring a lot of natural light into the room when closed and opened.
On the one hand, natural light is more economical, on the other hand, it looks much warmer than artificial light.
Interior bifold doors can make a valuable contribution to the atmosphere of the living room, especially on sunny days.
In fact, bifold doors offer the option of very large openings and also allow the expansion of adjacent rooms. This feature is very useful both outdoors and indoors. For example, a garden or a terrace can be connected to the bedroom.
High-quality custom bi-fold doors
The frames of our folding sliding glass patio doors are made of aluminum or wood-aluminum. Aluminum is very popular due to its easy-care properties, but the combination of wood and aluminum is also often preferred by customers for its natural look and high insulation properties.
Nowadays, windows and doors do more than just create a lockable passage or keep out the wind and rain.
In addition to burglar protection, energy efficiency is also one of the tasks today. Thermal insulation is becoming a central issue in modern window and door construction.
Special window glass makes a significant contribution to thermal protection, but the frame is also an important part of the entire system.
Even the best glass is useless if the heat escapes through the frame.
This usually happens via so-called thermal bridges, which occur when the thermal conductivity of the materials used is different and allow heat to escape to the outside faster at these points.
This not only leads to annoying energy losses and pollutes the environment, but also causes condensation. This condensation in turn promotes the appearance of mold, which is often harmful to health.
Removing mold - especially when it has already penetrated the adjacent masonry structure - is an extremely complex and expensive task. Therefore, every homeowner should pay close attention to the thermal insulation of their doors and windows when buying them.
We offer the best customizable bifold patio doors, which means that the color design of the bifold sliding door depends entirely on your personal taste: the aluminum-clad wooden frame opens up a wide range of possibilities, while the aluminum frame benefits from a special coating process, all of which are available in RAL colors and perfectly complete your door and window design.

Get Every Answers About bifold doors
Bi folding glass doors vary in price due to their opening mechanism and frame material. Our aluminum bifold doors cost around two thousand dollars. In addition to the material, the size of the folding door and the number of leafs play an important role in the overall cost. In addition, the choice of wood type, color and features of the aluminum clad wood also affect the price.
Glass bifold doors provide spacious openings that turn a terrace or garden into a second living room. The number and width of the sashes are particularly important for the size. In our custom requirements, you can equip the sliding door with up to 7 leafs and a total width of up to 10 meters. You can decide for yourself whether the entire door should be equipped with folding hinges. If required, one wing can also be used as a normal swing door.
Security is particularly important for folding patio doors, as thieves often choose ground-level windows as targets. To increase the protection against theft, you should pay attention to high-quality accessories and suitable security equipment when purchasing. In addition to safety glass, we can also provide higher-grade folding doors locks and hinges according to your requirements.
As a custom window and door manufacturer, we produce almost all of them in non-standard dimensions. Simply contact us and let us know the total width and height of your opening, and you will receive a custom window and door made to the millimeter. Unlike other patio doors, the width of the individual leafs of bifold windows and doors cannot be changed, as they all have to be the same size due to the special opening type.
The folding patio doors we manufacture not only guarantee comfortable operation, but also optimal sealing and thermal insulation. This is ensured by the construction of the running track, in which the individual elements and hinges are guided, so that the door closes absolutely tightly. In addition, all profiles are of course equipped with high-quality seals.
