ᐅ Empty conduit from the utility room to the attic, 50 mm – sufficient

Hello,

I am currently wondering if an empty conduit with a diameter of 50mm (2 inches) from the utility room to the attic is sufficient. The satellite system cables are to be installed through it.

Does anyone have experience with this?

Thanks

Expanding foam is not airtight – if you use HT pipes, you can simply seal them.

In our case, the empty conduits are laid as corrugated pipes. How can I seal them airtight? Another option might be duct tape, but that probably won’t be a long-lasting solution either.
Maybe spraying acrylic or silicone? But with the 40mm (1.6 inches) pipe, that might not work very well either, right?

Yes, I would use tape – plenty of it, but no expanding foam, it’s messy anyway...
