Polyurethane Foam Application: Lighting Equipment


Status: Active
Document ID: 100662

There are numerous luminaire types on the market that have been tested and are rated for use in contact with insulation material utilized in building construction.  However, the testing procedures and assumptions of this rating are associated with blown-in or batting-type dry insulation.  The insulation material which covers the luminaire reduces heat flow from the luminaire that would normally be transferred to the surrounding air.  Equipment safety testing takes such reduced thermal flow into account during the testing to achieve an IC rating. The use of liquid spray-in place expanding foam has started to see application as another type of insulation used in buildings in the past few years.  Although it has excellent insulating capabilities, its characteristics are markedly different than blown-in insulation. This white paper provides information regarding practical aspects of applying spray foam insulation that may come into contact with luminaires in various building applications.
