All Attic Protrusions Need CanCoverIt™
UCSD Engineering Capstone Project Conclusion:
“Based on both the summer and winter conditions, the CanCoverIt improves the insulating efficiency of the home. This means that less energy is required to sustain a comfortable household temperature, leading to savings in both electricity costs and greenhouse gas emissions.”
CanCoverIt Is Essential For:
Non-IC & IC Can Light Fixtures
Bathroom Vent Fans
Ceiling Fans
Air exchange Fans
In-Wall & In-Ceiling Speakers
Electrical Junction Boxes
CanCoverIt's Radiant barrier combined with non-conduction mold and fire resistant core stops water, air, sound and energy transfer to optimize overall attic R-Value and U-Value.
CanCoverIt is not just for energy efficiency, but also health, safety & overall building performance. CanCoverIt™ even improves the performance and lifespan of LED lights!
“Purchased a home built in 1961. The original (6) recessed lights in the main room are all made of metal and are not IC-Rated, so there was a fair amount of energy loss. The units are functional and accessible from the attic, but replacing them would require a great deal of effort and money. ‘CanCoverit’ presented the best option for stopping the energy loss and improving the Thermal Barrier in my home. Installed the units about a year ago and I have noticed temperature improvements. Good product and works as advertised. Thanks!”

Flexible Airsealing for Attic Fixtures
Data from Johns Manville Research
Built a 24”x24” ceiling section, with a 6” can light in it and ran a series of air leakage tests, at 50 Pa (same as for a blower-door test on a real house)
| Fixture Set Up | Effective Open Area (in") | Leakage @ 50 Pa (cfm) | Reduction in Leakage (%) |
|---|---|---|---|
| IC rated 6" fixture no trim | 2.64 | 33 | |
| IC w/ CanCoverIt Low Profile | 0.95 | 11.8 | 64% |
| IC w/ CanCoverIt Low Profile, sealed | 0.06 | 0.8 | 98% |
| IC w/ CanCoverIt Universal | 1.1 | 13.8 | 58% |
| IC w/ CanCoverIt Universal, sealed | 0.21 | 2.6 | 92% |
| IC w/ CanCoverIt Universal, sealed, vents removed | 1.37 | 17.1 | 48% |
Real World Tested
Study from Dan Ignosci under Comfort Advisors home contractor company:
“We had a blower door available to quantify the measures as they were implemented. The outcomes are listed below:
4534 cfm - Building leakage (leakage) when the attic deck was clean
4387 cfm – Leakage after sealing foam was applied to attic penetrations
3292 cfm - Leakage after CanCoverIts were sealed around 25 recessed light cans
2845 cfm – Leakage after R38 of cellulose was blown onto the attic deck "
CanCoverIt = 27% reduction in airflow
~ 40CFM reduction in leakage per penetration!
Air Sealing & Thermal Conductance Protection
“Before using the product our can lights would drip condensation into the house on very cold winter days when the warm indoor air met the cold attic air at the top of the can lights. I installed the CanCoverIt over a dozen lights, and this winter there was no more condensation dripping. I'm sure we're wasting less heating fuel too. Installation was very easy in the attic; simply unfolding the covers, placing them over the can fixtures and sealing them down using Great Stuff foam.”
- Customer Ben Minshall
Observed problems caused by metal ceiling penetrations:
Radiant hot and cold spots in the ceiling resulting in extreme energy loss.
A/C and Heater cycling and air drafts.
Moisture and condensation build up leading to mold growth.
Water stains, drips and ice crystals on the ceiling around fixture.
Light bulbs overheating, flickering and shutting off - premature failure.
Left untreated, metal fixtures bleed energy due to extreme conduction and convection energy loss, reducing overall home efficiency.
Attempts such as airtight fixtures, insulation contact fixtures, cardboard/drywall boxes all fail to solve the core problem, and in fact create larger unintended problems!
To solve the core problem every single fixture must be isolated from the attic environment.
CanCoverIt Airtight & Thermal Protected
Air-tight IC-Rated Can-Lights were once considered a solution but in fact they create new even worse problems.
Effectively isolating the fixture requires more than just stopping airflow! Because metal is conductive, attracts condensation and leaks radiant energy.
CanCoverIt™ is the ideal fixture companion.
"CanCoverIt allows the customer freedom to choose whicever lighting fixture they want while still achieving the best airsealing possible." - James Mallory, president Environix, WA
Only CanCoverIt™ has the required geometry, radiant barrier and non-conductive core to effectively isolate the fixture from the attic and bring it safely inside the conditioned interior air.
Optional Venting
With Vents Removed CanCoverIt Still Protects & Offers Safe Operation for Older Non-IC Fixtures.
CanCoverIt Universal Series provides optional safe venting for all fixtures, designed for Non-IC, and creates a dynamic thermal equilibrium chamber to control conduction and convection, greatly enhancing overall home efficiency and comfort.
Even with venting CanCoverIt Universal is still mitigating airflow and stopping thermal transfer.
CanCoverIt Low Profile Series is for IC-rated fixtures and has no vent yet offers a large air chamber inside to protect from overheating. Ideal for modern fixtures with LED lights.
Only CanCoverIt, both series, will provide the correct ambient operating temperature to allow LED bulbs to function best and last longest!

Whole System Approach
Other solutions have proven ineffectual, only CanCoverIt is designed to work with the real world and solve all issues related to metal attic penetrations.
As an example:
A Seattle Washington mold mitigation company used CanCoverIt successfully for fixing can-light related mold problems.
But later they tried switching to LED inserts. Soon after they emailed a large order and said:
“We’ll be back on track for ordering more and more of these. The LED retrofit, just didn’t work as well as [we were] thinking, so we’ve gone back to these on a more regular basis. Have a great day!”

Our installers love it because it helps them complete their work faster, and I love it because I now have confidence that my team is using the right product to safely cover can lights in the home."
- Donna, contractor, Virginia Beach, VA
"Before I installed the covers I used a laser temp gun to check the temperature of the light 'buckets' with the light off for a significant amount of time and again after the covers were installed. The temperature dropped around 10º F. The hot air draft in the house has now stopped and the house remains cooler during the day."
- Todd, Midland, TX
"As I prepared to upgrade the efficiency of my home, I wanted to find solutions that would protect the home and be safe for me and my family. After working with my local electrical and fire code officials to find the best product, they both agreed on CanCoverIt. I am happy to have found CanCoverIt, because I sure wasn't looking forward to building boxes out of drywall."
- Michael, owner of a 100-year-old home, Boston, MA
“Love your product, thanks for making a simple affordable project for saving energy any homeowner can do. Now I can afford a great warm tropical vacation.”
- Kris Chernik, Palmer, AK
"No other product addressed my concerns as well as CanCoverIt. All told, I used 21 covers to cover 17 can lights and 4 speakers. It was very easy.”
- Garrick Gallagher, Phoenix, AZ
"The [CanCoverIt™ units] have been working as advertised, we noticed a difference as soon as they were put in, but also did a series of other improvements, radiant barrier in the attic reduced overall attic temp about 10 degree's which helped support the can covers. With both changes the house temperature was cooler and stayed cooler throughout the day."
- Trevor Sim, Hawaii
