A spray insulation is referred to open cell or closed cell because of the difference between the small bubbles (cells) that make up the foam. Open cell foam is full of cells that aren't completely encapsulated. In other words, the cells are deliberatly left open. This makes the foam a softer, more flexable material.

Also, can you spray foam insulation yourself? A: Tom Silva replies: Spray foam is great insulation, but it's fairly demanding to apply; the kit instructions have to be followed exactly. Then fill any gaps between the edges of the foam boards and the joists using the canned spray foam sold at home centers or hardware stores.
