Polyurethane Foam Application: Lighting Equipment
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.
