Technical Details

Koehnlein Doors come in standard sizes, therefore the building must be adapted to the available sizes.

Width and Height

The dimensions of the internal doors are specified by the size of the door leaf (TBAM). From this, the other dimensions are as follows:

  • TBAM – Door leaf outer dimenson
  • LDM – Clear opening dimenson
  • ZFM – Frame fold dimenson
  • FAM – Lining outer dimension
  • WOM – Wall opening dimension (structural opening)

 

Wall Thickness

The wall thickness determines the thickness of the frame (nominal thickness). The following shows which thicknesses are possible. Some wall thicknesses cannot be accommodated. In that case, it is either not possible to use a Koehnlein Internal door, unless the wall thickness is changed.
