Hi almuart,

Marvelseal 1311 was specifically designed for attaching to wood crate walls and wood storage surfaces. It has the same barrier materials found in 360, plus a textured polycotton-scrim facing that is meant to grip adhesives better than the smoother product. The texture shows on both sides. We keep a roll of 360 in stock, and have tried a roll of 1311. My shop did not notice a compelling difference with the roll we tried. Both attach to wood crate walls fairly adequately with simalfa, a squeegee and plenty of drying time. (We also wrap it just over the edges prior to assembly for a little extra grip.) Both hold ethafoam pads in place with a generous application of hot glue. I did not try the 1311 with plastazote or XPS insulation before we finished the roll.

Still, the texture of 1311 should give it an advantage over 360 with applied adhesives. We are not yet convinced there is a pressing need to make the switch, but I recommend checking it out.
