Types of Housings
Halo Recessed Lighting
"T" Housing – Non-Insulated Ceiling (Non-IC)
Type (T) thermally protected housings (Non-IC) are designed for
use in non-insulated ceilings. When installed in a ceiling with
insulation, the insulation must be kept 3" from all sides of the unit
and there must be a least 1/2" clearance from the top of the fi xture
to any ceiling material. The integral thermal protector or insulation
detector on Halo recessed fi xtures provides positive protection
against misuse of ceiling insulation and overlamping by cycling
the lamp on and off until the problem is corrected. Halo fi xtures
with ballasts or drivers are thermally protected in the unit. To meet
specifi c municipal standards, many fi xtures in this category carry
an "IP" rating.
Insulated Ceiling (IC)
Insulated Ceiling type (IC) rated luminaires are tested to UL 1598
standards for installation with blown-in or batting-type dry
insulation materials. This allows the insulation layer to remain
unbroken and prevent heating and air conditioning losses. These
housings are also equipped with thermal protectors to guard
against overlamping by cycling the lamp off and on until the
problem is corrected.
The blown-in or batting-type dry insulation allows convective
heat transfer away from the recessed light fi xture, and allows
direct access to the luminaire for inspection and servicing. Type
IC luminaires are not for use in direct contact with spray-in foam
insulation. Spray-in foams should be kept 3" from all sides of
recessed luminaires. Alternate installation when spray-in foam is
used, might include but not be limited to, wrapping the luminaire
in fi berglass batting to maintain energy effi ciency while preserving
access to the luminaire. Refer to National Electrical Manufacturing
Association document: NEMA LSD57-2013, "Polyurethane Foam
Application: Lighting Equipment."
Air-Tite
™
(AT)
•
Air-Tite fixtures are designed to reduce airflow between
heated or air conditioned spaces and unconditioned areas
•
Standard recessed housings may allow up to 5.0 cubic ft. per
minute of air leakage to escape into unconditioned spaces
•
Air-Tite fixtures reduce this leakage by sealing air pathways
•
Air-Tite fixtures may be IC for use in insulated ceilings
or they may be Non-IC for non-insulated ceilings
•
When an IC housing is Air-Tite that combination meets
California Title 24 residential compliance
•
Other state energy building codes now have restricted
airflow requirements for recessed lighting fixtures
•
Air-Tite fixtures are test certified to the American Society for
testing and materials procedure ASTM E283 as having an air
leakage rate not more than 2.0 cfm (0.944 L/s) when tested
at a 1.57 psf (75 Pa) pressure differential
•
Additional benefits include: Savings in HVAC bills, preventing
moisture damage to attic areas, reduced sound transmission
between floors, and eliminating drafts for greater comfort
