4m window front with a breathtaking view
The 4m-wide window draws everyone’s attention. The breathtaking view gives the impression that you can be in the fresh air in just one step. The effect on the atmosphere of a room is correspondingly significant. The 4m window is imposing as a panoramic window with full glazing. It can also be realized with several wings and a central post as well as rung decorations. There are many options for opening type and window design.
Examples of maximum glazing surfaces
The calculation of the maximum glazing surface depends on various factors such as wind load, ambient temperature, or height above sea level. Not all glazing options are feasible for one piece width of 4m. In the case of large glazing, it is also advisable to use toughened safety glass (ESG) to protect people. ESG glass has increased shock and impact resistance compared to normal flat glass. Due to the greater thickness, large glazing surfaces are more expensive than standard glazing. A cost-effective alternative is dividing the glass surface using multi-leaf elements or a transom (transverse beam).

Look into the distance with large windows
Large windows are every homeowner’s dream. They not only provide bright and warm light but also plenty of space and a harmonious atmosphere. Whether as a panoramic window or casement window, the effect on the house is unique!
Even wide window models can be brought together to form a large window front using certain coupling elements. If a window sash is fixed, the large window itself can be opened with a sliding function and saves you additional space in the room.
But do not assume that large windows lead to heat loss. A high level of thermal insulation can be guaranteed with special functional glass. The so-called thermal float protects against heat loss in winter and against overheating in summer.
Frequently asked questions about 4m-wide windows
In which price range are 4m-wide windows?
The 4m-wide window is in a higher price class due to its size. Depending on the glazing surface, a unique glass structure may be necessary, which pushes the price up. An alternative is the division of the glass surfaces by a so-called impost. This means that inexpensive standard glazing can be used again.
What treatment should the glass of a 4m-wide window undergo?
For particularly large glass surfaces without a stabilizing transom, we recommend ESG glazing. With ESG glazing, the glass is quasi-shocked by high-temperature differences and is highly shock and impact resistant. The glazing protects against burglary and reduces the risk of injury with broken glass.
Can I choose aluminum instead of steel as the window profile for my 4m panoramic window?
Yes, that is possible. It depends much more on the glazing surface and other factors, such as wind load, temperatures, and the facades’ stability, to what extent a panoramic window can be realized.
