Corner windows - costs and benefits


The cost of a corner window depends on several factors. If a corner window completely without visible frame and without a support to be installed in the corner, the cost, of course, increase significantly. However, this is not always absolutely necessary, because even conventional windows can be made into a corner window. Here are some prices and the price factors.

Frameless - levitating

If the corner window with the invisible frame is well cleaned, the ceiling seems to float freely in the corner. However, the opposite is of course the case and the special design increases the cost of this construction very much. The corner of a building has important static tasks; if it simply lacks, the load must be diverted elsewhere.

Aluminum corner windows

Of course, frameless corner windows have never been installed without a frame. However, the frame disappears in the wall or consists only of a thin aluminum frame. The less frame you choose, the more likely you will not be able to open the window later. So if the window is used for ventilation, you will never get a completely frameless appearance.

Examples of different construction methods

In addition, you have to keep in mind that most window manufacturers only offer the optically frameless windows in the already more expensive aluminum version with wood core.
