Lookup Value?: ICAT Recessed Lighting

From Lookup Field?: ConstructionMaterials Lookups

Definition (May contain conditions that must apply)

ICAT recessed light fixtures are rated both to safely come in contact with insulation and are better airsealed. ICAT is an acronym for Insulation Contact/AirTight. They can be installed safely with insulation and air sealing. These lights are different from IC (Insulation Contact) fixtures, which are not very airtight. They can also be identified by the wording “Washington State Approved.” Documentation on the installation is recommended because ICAT rating often requires multiple components be used as specified by the manufacturer. Substitutions of components can negate the rating. See: and
