Open cell spray polyurethane foam insulation being applied in wall cavities. Open cell insulation can be crushed in your hand and has a lower insulation value. Closed cell is rigid to the touch and each air cell is completely sealed. While closed cell foam has a higher R-value, it is more costly to buy. [9] Medium-density closed-cell spray foam ...
Closed cell polyurethane foam can be used as backfill in applications where the high density and compression strength of concrete are not necessary. [22] In addition to being considerably lighter than concrete, the closed cell nature of the material prevents the transfer of moisture to the structure being supported which can reduce the risk or ...

Closed-cell foam is non-porous, and not moisture-penetrable, thereby effectively forming a semi-permeable vapor barrier. (N.B., vapor barriers are usually required by the Building Codes, regardless of the type of insulation used. Check with the local authorities to find out the requirements for your area.) Closed-cell foams are superior insulators.
Styrofoam insulation extruded polystyrene foam (XPS), owned and manufactured by DuPont. Styrofoam is a genericized trademarked brand of closed-cell extruded polystyrene foam (XPS), manufactured to provide continuous building insulation board used in walls, roofs, and foundations as thermal insulation and as a water barrier.
A foam is considered open-celled if at least two of its facets are holes rather than walls. [18] In this case the entirety of the load on the foam is on the cross-beams that make up the edges of the cell. [6] If no more than one of the walls of the cell are holes, the foam is considered closed-celled in nature. [18]
