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. :D
