Possible distance

Removal can only be achieved by sawing the frames into individual parts with a cutting disc, and then severing the existing anchors (usually 3 per side) one by one. Then the built-in frame can then be removed by force.


Since the removal of a steel frame seems less promising, you should think about alternatives. Possibilities are:

  • the sheathing of the steel frame with a so-called renovation system with standard dimensions of the frame
  • the production of a sheathing of the frame in an individual measure (for example by a carpenter)
  • the foiling of the steel frame with foils in matching wood look

The first two options may be quite costly. For common dimensions in the steel frames can be expected in a renovation system of prices from about 120 - 130 EUR, individual sheathing, however, are significantly more expensive. The cost of a foiling depends on the respective provider and start at around 40 - 60 EUR per frame including cutting.
