I would like to renovate our detached house built in the 70's in the near future. I plan to expand the living space with additions (wood posts and beams) and repair/insulate the façade and roof. I plan to use wood fiber insulation boards to insulate the façade and roof, as well as the extensions.
Now to my question:
I would like to design the new façade and roof with large (dark) façade panels.
Eternit products have caught my eye, but the price of the material scares me.
So I'm wondering what alternative materials and manufacturers you could recommend? For me, both fiber cement and plastic panels would be fine. Or would you have a clear preference for one material? If so, why? I would like to use panels from 150 x 75 cm ... I would also like them to be larger. The price per square meter should be much lower than Eternit. It could also be a manufacturer from another country.
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.
Alternatively, consider "square wood" at your desired insulation thickness. Insulate the compartments with mineral wool / rock wool. Then black (UV resistant) façade sheeting, to which the façade panels are attached with spacers (painted black counter battens). Small gaps between the panels don't matter, the backing will keep a small amount of rain/wind out of the insulation. We just clad the Trespa attic and a few other places, and I was quite happy with the material, even if it's not "natural". It just has to last almost forever.
Allblack photovoltaic modules?
The color fits. The size fits. Alternative for the roof in any case.
I think it is fundamentally wrong to start such a project with façade panels. Unfortunately, it is a common mistake of non-professionals to start with something you have no idea how to implement, according to the motto "get the stones out of the way". In other words, you brainstorm all the things you want to do, and then see where you can check the "I already know roughly how to do it" box; in the next step, you formulate questions from the unchecked lines of your plan and ask them of the all-knowing Internet. It sounds logical and clever – but, unfortunately, it only seems that way. Because the details remain details, and thus a tail from which you shouldn't stick your horse out. My advice is the tried-and-true order: "Build (the main thing) first, then (the aggregate of the existing building, alterations and additions) do the hair and makeup."
