If you are building in any of the high-fire areas of Santa Barbara County, Icynene is perfect because its complete insulation eliminates spots where fire can enter a home. Additionally, it is not necessary to vent the attic space, which is required with normal batt insulation. The money saved not installing attic and eave vents helps offset the cost of Icynene. Because Icynene completely fills any crack or crevice, the complete insulation and air barrier solution is very energy efficient. On average, Icynene typically pays for itself in three to four years – an excellent return on investment for any homeowner.
