2 part split frames for subsequent installation are the best solution for renovation sites. These frames can be installed either into a finished wall opening during the building phase or into a completed room or even on top of the old frames on request.
2 part split frames are available in a wide range of designs and fittings, for example with oblong cut outs for foaming, or as a corner frame with a special diagonal attachment for the wall. We highly recommend our well-tried and tested BOS powder coating in all RAL colours for the renovation frames.
The 15Z Bud is particularly easy to install because of
the patented levelling anchor with anchor guidance. The simple anchor
adjustment where necessary makes padding superfluous.
