I put a DIY kit to the test in my friend's studio shed to find out. Get the Mileseey S50 here: https://dada.link/YDxAJr I wanted to avoid fiberglass insulation because of the hassle and the itching, so I bought this Stanley spray foam kit instead. While the foam worked well and was easy to clean up, I made a DUMB mistake during the installation that you need to avoid. In this video, I'll show you: How the Amazon spray foam kit actually performs. The pros and cons compared to traditional insulation. The big safety error I made (so you don't do it too!). Now this shed is well-insulated and ready to finish out!
