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.”
Without CanCoverIt not even air-sealing can help: thermal transfer runs wild!
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!
Problems of Unprotected Fixtures
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.
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
Airtight IC Can-Lights still allow radiant energy transfer through your ceiling!
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 solves can-light and all other metal attic penetration problems.
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
With Vents Removed CanCoverIt Still Protects & Offers Safe Operation for Older Non-IC Fixtures.
Optional Venting
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.
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!
CanCoverIt: Designed For The Real World
Other solutions have proven ineffectual, only CanCoverIt is designed to work with the real world and solve all issues related to metal attic penetrations.
Go hands on with professional installers Comfort Advisors and see why CanCoverIt is the best energy upgrade for your home!
Learn more about CanCoverIt from the inventor David Hanacek
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!”
Testimonials from Pros & Homeowners
"The covers are easy to work with and we managed to get in and out in a single day with the added blown insulation. A nice safe & snug home and a happy client."
- Dean Alm, Napa Valley Home Inspectors
"Finding CanCoverIt has been amazing for me. It’s been a long time since something has come along that is as good and easy to use as CanCoverIt. Travels well, even comes shipped in a nice heavy box. Cut the product with a knife and scissors. Makes my life so easy and delivers the best results. I don't work without CanCoverIt.”

The Ideal Solution
CanCoverIt was designed after extensive research around the operations of can light fixtures, the bulbs that go in them, and the installers tasked with sealing them. As a result CanCoverIt is the ultimate solution to one of the home efficiency field's most pressing and difficult problems.
CanCoverIt controls fluctuations in temperature and ensures safe heat transfer with no excess waste.
CanCoverIt is the first practical, safe, cost effective, efficient solution for insulating non-IC can light fixtures providing complete residential solutions for both contractors and DIYers. CanCoverIt fills an overwhelming need for a safe economically viable and uniform insulating solution.
Our Universal Series features passive venting technology allows all recessed light fixtures to be insulated, even Non-IC rated fixtures.
The Low Profile Series is an excellent option for IC-rated can light fixtures.
CanCoverIt's design advantages:
| Fixtures Without CanCoverIt™ | Fixtures With CanCoverIt™ |
|---|---|
| Air leaks causing uncomfortable drafts, inconsistent room temperature and wasted energy | Eliminates drafts - Stops air leakage |
| Extreme attic temperature radiates through fixtures | Eliminates thermal energy transfer |
| Light bulbs overheat, flicker, shut off and fail | Light bulb heat safely and effectively diffuses within the CanCoverIt™ conditioned air space |
| LED bulb premature failure due to temperature changes | Provides consistent operating environment to maximize LED bulb life |
| Dew-point - moisture condenses causing ice crystals, water stains, dripping water and mold growth | Eliminates moisture buildup risk |
| Acoustic problems - Sound transfers through fixtures especially when located under hard surface floors | Air volume around fixture & insulation controls sound transfer |
| Compromises overall attic R-value, regardless of insulation thickness | Optimizes attic R-value, allows insulation to work effectively |
| Constant A/C and heater cycling depending on season | Reduces heating/cooling system cycles by over half |
Ships and stores flat.
Pop open and go, no assembly required.
Safe and durable to install and built to last.
An air-tight fit once sealed to the attic floor.
Easy to cut and fit around brackets wires, and framing.
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.
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
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% |
