  1. It’s interesting that foam insulation could be a good way to prevent pipes from freezing. It makes sense that insulation would be a good way to keep them from getting so cold because it doesn’t require maintenance. I’ll have to remember this for my crawl space because having it done after the repair is finished would be a good way to prevent problems in the future.
