What Is the California Unvented Code?

Most industries must adhere to guidelines set up by governing bodies designed to ensure safety and best practices. Insulation in Sacramento, CA is no exception. The California Unvented Code features recommended practices for insulated roof assemblies and other conditioned spaces.

These guidelines offer standards that should be followed for unvented attics. By following these regulations, property owners can improve their attic conditions and protect themselves from potential hazards. Following is an overview of this code:

  • Wood shingles and shakes: If this material is used for the roofing of the building, then a ¼-inch vented space should separate the shingles/shakes and the underlayment of the roof.
  • Air permeable/air impermeable: If air permeable insulation is applied, it should be rigid installation and must be applied above the structural roof sheathing. If air impermeable insulation is used, it should be applied directly to the interior surface of the roof sheathing.
  • Permitted spaces: Unvented attic assemblies are only permitted if certain conditions are met. First, it must be completely contained within the building. Second, the space must not have any interior vapor retarders on the ceiling side. Third, it must adhere to the previous two guidelines mentioned regarding shingles and air permeable conditions.
  • Climate zones: Regulations under the California Unvented Code differ slightly based on the climate zone of the region. The guidelines for insulation in Sacramento, CA may not be exactly the same as those for other parts of the state. Sacramento is situated in Climate Zone 3, which makes it exempt from some of the additional regulations regarding vapor permeability of the insulation.
