How do I best seal these pipes?

Hello,

How can I best seal these pipes that are embedded in a concrete wall? I have an insulated heated utility room under the terrace, and I am mainly concerned about two things:

1. That pests will get in and damage the technology
2. That heat will escape through the pipes.

I have a can of foam sealant at home, but I guess it won't stop any rodents. Some kind of cap for the pipe would be nice; are there any that can be put on after pipes and cables are already installed?

You fold chicken wire into suitable pieces 👍

You fold chicken wire into appropriate pieces 👍

What do you mean? Fold and push into the hole?

And expansion foam in the pipe as insulation I assume?

You can mix steel wool with the foam sealant. Spray in foam, then press the steel wool into it.
