Yaomiao3 Sheets Customizable Polyethylene Foam 54" x 16" x 2" Thick Black Packing Foam Inserts for Cases Thick Polyethylene Foam Sheet for Packaging and Crafts

I cut this material into smaller rectangles to fit in my foundation vents for the winter. Fills the hole and insulates at the same time. I had some vents that were not perfect 90 degree corners so this being flexible it was easy to fit them. Easy to cut with a decent insulation value. Easily pulled out in the spring and stored for next fall/winter. Work so much better than the rigid foam blocks.

This foam worked out great for protecting my equipment in the rolling pack-out. I have a 3 box pack out that consumed this entire pack. Happy with the results. Make sure to pick up the Kaizen foam cutting kit to make things easier on yourself.

Worked great for my product packaging

Does not hold up to any kind of sun or heat, even for an hour. It will blister and shrink badly.

Listing was for 54" length, all three sheets I received were just under 53". In addition, one sheet had a great number of imperfections, rendering it unusable. Now I have to deal with returning this?! How hard is it to measure and cut a piece of foam?! 2 stars is being generous...
