The standard reinforcing insert, the box end rail and the fixing strip integrated into the insulating wedge promise even greater stability and support. Particular attention has also been paid to the visually revised external panel. This has the same height inside and out and thus ensures a uniform appearance. Ideal for combined use with a roller shutter.
A clean appearance as well as high stability are made possible by the new side panel, which is produced by PVC injection moulding.
