Review on 🔒 Efficient Insulation: No-Adhesion Conditioner Weather Stripping by Andrew Gomez

I have used these to seal windows as they slide up and down. I have 12 windows in my apartment. I was able to finish 8 and felt the difference. It also muffles noise coming from outside. I cut them in half and it was enough for 2 packs (4 rolls in total). Let's see if I have to use plastic for extra insulation this winter. But these are so great.
