Is spray foam good or bad?



  1. 0 Votes

    Spray foam is good.  Among other things the U.S. Green Building Council considers a product green if it improves energy efficiency and is sustainable.  Spray foam seals a structure in a very efficient manner.  It will not break down over time, keeping an air tight seal.  This allows for much less energy to be used when heating and cooling a building.  Most foam is produced with approximately half of a petroleum based substance.  There are companies like BioBased (linked below) that are manufacturing foam with less petroleum in their products.
