Hello
Our facade is constructed as follows:
15cm (6 inches) sand-lime brick
19cm (7.5 inches) external thermal insulation composite system (ETICS)
Exterior render
A scaffold was set up at our building for photovoltaic installation.
How are the drill holes properly sealed afterwards to prevent thermal bridging or other issues?
I have the original render and paint and will provide them.
Is there a specific type of foam, acrylic, or something else used for this?

What material should it be made of?

Should it be the plug from Knauf, or does it not matter? It doesn’t matter. There are dozens of suppliers—however, the workers should use the plugs intended for the specific system (Knauf was just an example for the warm wall system) ==> this is only important for warranty purposes. Otherwise, it really doesn’t matter. Usually, it is a soft polyurethane (PUR) foam. You compress it by hand, insert it into the hole, and then it immediately expands (similar to a compressible sealing tape/window sealing tape). This is already considered to be rainproof.

FrankChief15 Apr 2024 19:34OK thank you
I had also seen some made of rigid foam
We have KfW55 standard, so I want it to be done properly
Then I'll tell them to use a PyuR soft foam plug
How long do you have to wait before you can dab paint onto fresh plaster?

Or is the backer rod better?
