Safety: Pass | Performance: Fail

• Most common fixture type with more than 500 million in use

• Heat entrapment prevention requires no Insulation contact

• Early versions have no thermal shut off mechanisms

• Later models may have thermal shut off set for high heat

• Metal fixture is highly conductive and can attract condensation

• Designed to draw air through fixture to prevent overheating

• Critical energy waster - severely compromises insulation envelope

Safety: Pass | Performance: Fail

• Efforts to improve energy efficiency added insulation thickness above fixture

• Safety code evolved to read: “no insulation above in a manner to entrap heat”

• Chimney effect phenomenon can draw more air through than untreated fixture

• Metal fixture remains highly conductive and can attract condensation

• Open attic space creates hot and cold spots and drafts in the ceiling  

• Critical energy waster - severely compromises insulation envelope

• Barrier use can negate overall R-Valve benefit of added insulation thickness

Safety: Fail | Performance: Fail

• Can effectively stop air flow through the fixture, but not around fixture

• Potential overheating hazard in hot ambient temperature attic conditions  

• Metal fixture remains highly conductive and can attract condensation

• Open attic space creates conductive hot and cold spots in the ceiling

• Can entrap heat and shorten the lifespan of CFL and LED light bulbs

• Not compatible with original Non-IC airflow intent to prevent heat entrapment

• Does not address conductive energy loss and compromises insulation envelope

Safety: Fail | Performance: Fail

• Flat top box terminates within insulating layer to improve R-Value

• Weak structure can sag or even collapse under the weight of insulation  

• Limited size provides insufficient air volume above and/or around fixture

• Incandescent bulb generates heat at a faster rate than it can dissipate

• Insulation blocked openings provide slow air venting and entrap heat

• Addresses conductive heat transfer, but is moisture and airflow permeable

• Concentrates high heat around fixture and sensitive electrical components

Safety: Fail | Performance: Fail

• Flat top box terminates within insulating layer to improve R-Value

• Provides insufficient air volume above and/or around fixture

• Flat horizontal top creates dam effect that impedes airflow and entraps heat

• Weak structure can sag or even collapse under the weight of insulation 

• Concentrates high heat around fixture and sensitive electrical components

• Incandescent bulb generates heat at a faster rate than it can dissipate

• Addresses conductive heat transfer, but is moisture and airflow permeable

Safety: Fail | Performance: Fail

• Flat top box (typically drywall) terminating above insulation layer (envelope)

• Size provides more air volume to dissipate heat, but compromises insulation

• Addresses airflow (convection), but not conduction and moisture conditions

• Non insulated top transfers energy and compromises overall home insulation (R-Value)

• Conduction alone may not dissipate heat at a fast enough rate to prevent overheating

• High heat concentrations within box may damage sensitive electrical components

• Closed box can entrap heat, with peak hazard occurring during hot attic conditions  

Safety: Fail | Performance: Fail

• Tent style sides can sag or even collapse under the weight of insulation

• Angled sides allow hot air to rise with less restriction than a flat top box

• Angled sides allow top area to be better insulated than a tall box

• However, the shape does limit top insulation thickness along panel width

• Shape limits compartment size and air volume in critical area around fixture

• Size to air volume ratio above and/or around fixture is not optimum  

Safety: Pass | Performance: Pass

• Stable base optimizes air space safety and makes installation a breeze

• Converging top panels provide thermal performance and strength  

• Turning the light on activates the safety mode to prevent overheating

• Materials are non-conductive fire and mold resistant, air and watertight

• Secondary covers protect the vents even when blowing in insulation

• Innovative design provides a lifetime of fail-safe energy efficiency
