Review on Black Frost King R538H Foam by Peris Auditore

I needed this to hide the gap between my french doors, not for insulation. It was too thick but too thin for the smaller size and the other options were more expensive than I was willing to pay. My research online has shown that this material naturally yellows over time, so I was prepared for that, but not for it to happen in just a week! But it still serves its purpose and was so cheap that I still give it 4 stars. I can paint over the yellow if it gets worse as I don't need it for insulation, just for privacy.
