I have made a hole in a wall to pass through pipes and cables. Now I need to close this hole to prevent cold air from coming in. Which junction box cover/cover cap should I use, or are there other alternatives? I got the diameter to 80mm.

That was a good idea. But it keeps falling off all the time. The clamps don't reach the wall's sides.

Could one use fogskun and then press the socket cover into place?
 
Cut a round piece of styrofoam or ground insulation and put it in the hole, seal with a little soft sealant, so it can be easily opened if needed.

Would foam plastic work?
 
Yes, it works.

Will there eventually be a need to change anything in the hole?

If not, then it's just a matter of filling the hole with foam sealant?
