I had my first insulation replacement. The section that went into the wall was such a tight space; I didn't believe I could wrap my new insulation around it. How was the old insulation so much thinner? I left that old insulation in there and used electrical tape to join the old with the new. It felt incomplete. Any recommendations? or just leave it alone?
On a side note, my tape wrapping skill is level 0. I found it hard in that space to have a clean smooth wrap. I'm thinking to use a duct tape (one wide piece) to cover the imperfection. 😀

We have sheets of neoprene insulation as thin as 1/8” all you need to do in reality is prevent condensation even spray foam in the hole allowing it to encapsulate the lines will be enough. Don’t worry about your tape skills you are really just preventing uv exposure as this breaks down the insulation. Tape also seals from air movement again helping to prevent condensation. You are ahead of some DYI by asking,,, good job.
