This is the answer to the question Inexpensive large format façade/roofing panels or manufacturer?
Revision 1
Hello, I find the combination of a curtain wall façade of large elements and wood-fiber insulation boards (Pavatex, Gutex, etc.) challenging from a construction perspective. The stumbling block will probably be the fastening. Wood fiber insulation boards are fastened with thermally decoupled dowels and screws. You won't find an approved system for façade panels directly on wood fiber panels. Fixing the facade panels directly to the supporting structure will be difficult: which screws / dowels?
The combination makes no sense. I personally know the developer of the facade panels and have followed the development of this direction a bit. We were talking about industrial/functional buildings here, but by no means should you just screw panels in any way (suction, etc.) If the panel falls from a great height, it poses a great danger.
By the way, Trespa may be the appropriate material.
Light-colored panels are usually cheaper than darker ones because lighter colors and pastel shades are much easier to make UV-resistant than darker (wood-colored) ones. UV protection is extremely important for plastics.
