"Older [can] lights run hot, and attic insulation cannot come within three inches of the light due to fire hazard. [CanCoverIt] both brings the light to code and adds legal/safe way to add some R value to the [can] light."

How It Works

CanCoverIt goes to work right away and keeps working for the life of the home. The secret is a unique combination of high-quality FSK and truly innovative engineering that is designed to work with the heat, not against it.

Left untreated can fixtures bleed energy due to extreme conduction and convection energy loss, reducing overall home efficiency.

CanCoverIt provides safe venting and creates a dynamic thermal equilibrium chamber that controls conduction and convection, greatly enhancing overall home efficiency.

The Science of CanCoverIt

The insulation layer is a non-conductive buffer zone that separates the extreme outside air from the conditioned inside air. However, effective treatment around Non-IC fixtures presents a safety vs. efficiency dilemma.

The breakthrough in solving this challenge was treating the insulation layer as two distinct zones and balancing their perspective requirements.


The area directly around the fixture, Zone 1, is the safety zone and must provide open air space to safely diffuse high levels of heat generated from the light bulb. The large square base geometry provides optimal air volume within the space confinements to best disperse heat for maximum safety.

Conversely, Zone 2 must optimize energy efficiency. The converging panels geometry allows for safe air circulation, while reducing exterior exposure area and allowing for optimum insulation.


Designed To Work With Thermodynamics


The innovative design reduces open, exposed area from previous treatment options by over 98%, effectively isolating the conductive can-light fixture mass from the extreme attic air.

When the light is off, the system achieves a passive equilibrium with the conditioned air inside the home resulting in increased comfort and exceptional energy savings.


Turning on the light activates the controlled airflow mode that safely vents out excess heat, preventing overheating while maintaining insulation.

CanCoverIt's innovative application of geometry and thermal principles join forces to create a passive device that functions as an active system.

Requiring no mechanical parts, the system utilizes the light bulb heat itself as the On/Off switch.

The result is an extremely energy efficient, maintenance free, safety compliant and fail-safe lifetime solution.


What About IC-rated fixtures?


All fixtures, even IC rated, should avoid insulation contact. Best practice requires an appropriate airtight cover that isolates the fixture from the attic conditions, while still enabling air circulation with the conditioned ambient air.

Why? Although air sealing the fixture itself, or at its substrate contact, may mask some problems, it does not fully address the root cause because the fixture itself is the problem! 

The can-light's largely metal construction is a highly conductive thermal mass that transfers energy and continually seeks equilibrium with its surrounding environment.

Even though insulation forms a gradient buffer zone between the unconditioned and conditioned air spaces, it is still a volatile area subject to the extreme attic conditions of temperature and humidity.

Insulation is temperature, airflow and moisture permeable, thus placing the fixture within this zone subjects it to these extreme conditions, regardless if the fixture is airtight or not. Likewise, merely using a permeable fiber cover does not effectively address the problem. The solution must isolate the fixture itself from the temperature, airflow and moisture issues.

A common problem associated with insulation contact is trapped heat that causes "flickering" lights due to overheating. Besides the obvious annoyance, this inability to dissipate heat can be detrimental to sensitive electronics, particularly expensive LED bulbs. Also, the recent severe winter provided vivid evidence of moisture related problems manifested as “ice-overs” and drafts, but even during more moderate weather the fundamental shortcomings remain.

Our Low Profile series provides an airtight chamber integrated with the homes conditioned air space to promote airflow circulation even from minor temperature fluctuations of an LED light.
