Copper insulating

Insulating the copper pipes in a crawl space. The pipes did freeze once this year already.

My question.. i wrapped all the pipe with the 6 foot pieces of foam. Zip tied every few feet. On the elbows i just continued the foam around and made slits in the insulation to make it fit best and zip tie.

Will very small exposed copper cause an issue in some spots?

I am thinking about going back and taping where all the new 6 foot pieces butt up to the other. Also taping around the corners just in case. What tape should i use?

It's all degrees and shades of gray... Is some bare copper showing good, no. It's a place where the pipe is exposed to the cold and may freeze. Is it the end of the world, no. If it's just a little spot it will be partially protected by the adjacent, insulated pipe but it is a point of weakness where it is more likely to freeze in the future. Taping joints and seams is a good idea as it can help stop air infiltration. I generally use high quality electrical tape.
