Here we come to our 5th group of wall types -- special facades -- those for which trellises cannot be mounted using standard mounts or fittings. Specifically, these are: cladding, panels and plates, metal profiles and tubing, etc.. (thin concrete walls are treated separately). Modern buildings with both insulation *and* external cladding belong to this group. Most trellising technology can also be applied to special and wooden facades. We'll first introduce you to nine typical substrates, followed by 8 subpages describing mounting variations ('methods'). Most solutions are also valid for wooden trellises. Please note: with some climbing plants, the shoots can climb into cracks and crevices and affect the integrity of the building (possibly leading to structural damage).
