Glass canopy without posts - What kind of attachment is used in ETICS?

...

It is also one of my topics, so I’m going to cheekily join this thread. ;-) Would it be reasonable for you to take a photo for us and show it here? Thanks in advance, but of course you can also say "no." :)

we have 24 cm hollow brick (Poroton)

The type of fastening would then be the "specified" dowels for the bricks.

The size of the porch roof depends, among other things, on the entrance situation. North/South/West...
A side panel is often advantageous. Then the idea of "no posts" is already off the table.

I would choose what I like, the fastening will follow.

We have combined porch roof + side panel with stainless steel and railing (since there are steps to the entrance).
Gutter with chain.
Today I would solve it differently. Instead of a chain, a drain integrated into the carrier.

It is usually advisable to drill into the suspended ceiling. Or do you have a bungalow?

Right, dowels in the concrete intermediate ceiling would certainly make the most sense. Because above the front door not much structural stability would be expected.

I'll see if I can find more photos. I can't say any more details off the top of my head.

You can see the beam there. A bit of sealing seems to have been applied. Nothing else was insulated. The insulating effect of the wood is certainly much worse than that of the [WDVS] - but it's still better than nothing. So far (six years) nothing noticeable can be seen inside. Outside, there is the conservatory in front. How professional this is, I do not know.
