Preparation for terrace roofing before external insulation systems (Wdvs)

Hello everyone,

I am currently planning to insulate the facade of my house with an 18 cm thick ETICS.
This year, I want to install a 6 m wide aluminum terrace roof with laminated safety glass on this facade.

Since several attachment points will be necessary for the roof, I want to prepare the facade now so that I can later carry out a secure and as thermally bridge-free as possible attachment.

My questions to you:

• How can I sensibly prepare the facade if the exact position of the drill holes is not yet 100% determined?
• Are there proven solutions to safely transfer high loads to the facade later on?
• How would you generally proceed here?

Thanks in advance for your tips!

You need a few heavy-duty brackets that you install beforehand. There are, for example, from Dosteba.

I wouldn’t do anything there beforehand. The risk that it won’t fit height-wise afterwards is far too great. Finish the WDVS and for attaching the wall profile you then get the brackets mentioned in the post before. Anything else would be "putting the jacket on before the undershirt" and is not effective.

Aren't the consoles installed under the facade before the plaster is applied? The facade is definitely supposed to go into the suspended ceiling, so I want to prepare something there.

Thermax dowels/screws from Fischer. Can be done afterwards.

I would do it the way almost 100% of my neighbors do. Put the canopy on 4 feet, 2 of them directly at the facade. You won’t get it without thermal bridges; some brackets are made of steel, the canopy of aluminum. And the bracket must be directly on the masonry stone, how should no thermal bridge be created. They also have to be correspondingly large brackets, as they are supposed to carry snow load, wind load, etc. What is your masonry made of? Is that even statically possible? I would never do it without having a structural engineer calculate it. On a 6x4m² large terrace roof, in a harsh winter, there can be 1.5 tons of snow. That's a car. And as a previous speaker already said. To fix something at that height, house, terrace, etc. finally standing... that can only go wrong. I represent the philosophy of drilling into the facade as little as possible. In 5 years you might want something completely different and then you have the mess.
