Review on 🌽 Warp Brothers SP-4CH10-C Clear Plastic Sheeting: 4 Mil Carry Home Coverall, 10ft x 25ft - High-Quality Protective Coverall for All Your Needs by Alex Jain

So much. Plastic. I had to seal the windows for the winter as they are very drafty. This plastic covered my sliding glass door with a sheet and was able to cover 3 other large windows and 2 smaller windows. I definitely have a good chunk left. It really helped lower my heating bill. For example before my plastic surgery my heater was on (set to 65) about every hour and now the heater turns on about 4 times a day which is great for me! But a word of caution: the sheet is just one giant piece, so you should start by cutting out the largest piece you need and then move on. Also, it's not "transparent" plastic, it's a little cloudy, but you can still see it.
