Rule Your Attic Lest It Rule You! 

If you have a home with recessed light fixtures –those lightbulbs in the ceiling – and bathroom fans, you need CanCoverIt.

All metal fixtures, including air-tight ones, leak energy! 

All metal fixtures, including air-tight ones, leak energy! 

Those fixtures are metal, so even insulation covering them cannot stop their intense conduction. So when the attic is hot, those can-lights and bathroom fans are bringing heat in directly, when the attic is cold that cold is infiltrating through the fixtures. Even if you have used air-sealed IC rated can-lights, you still have this problem. In fact, with air-sealed can-lights homeowners often have deeper problems show up when they’re most inconvenient: from moisture build-up to lightbulb failure.

CanCoverIt can eliminate drafts that persisted even after air-sealing work was done. Many drafts in your home are caused by the thermal transfer of metal fixtures moving the air inside your home around, not necessarily outside air coming in.

You need to protect your metal ceiling fixtures from the wild temperature swings of your attic, and the fastest, easiest, most effective way to do so is with CanCoverIt. It’s so easy that you can do it yourself, provided you can get up into the attic. If you don’t want to crawl around, hire a local contractor and get them to install CanCoverIt. A CanCoverIt and blown insulation upgrade will take just one afternoon.

Make sure to demand any installer use CanCoverIt. There are other recessed light covers on the market, but they all fail in one dimension or another. The ones that look like flower pots still let moisture, air and thermal energy through; all they do is keep insulation off of the fixture. The flower pots cannot and do not solve the core problem of ceiling fixtures, they are a waste of your time and money.

Cardboard boxes and flower pots will fail over time, and don't have enough insualtion anyway.

Cardboard boxes and flower pots will fail over time, and don't have enough insualtion anyway.

Also watch out for cardboard boxes, even ones that say they are chemically ‘treated.’ These will sag over time under the weight of insulation, and still pose a greater fire risk due to their main material being cardboard. Moreover, cardboard boxes, even chemically treated ones, do not have the correct insulation properties to actually solve any problems. They too are just to keep insulation away from the fixture, and they will fail that job over the course of time.

You need to demand that only CanCoverIt goes up in your attic.

CanCoverIt brings your metal ceiling fixtures out of the attic and into the house air, so they no longer cause you problems and are much more protected.

Only CanCoverIt has the correct combination of insulation and radiant barrier to protect your interior home from all weather conditions, moisture buildup, mold and pests. Only CanCoverIt will prolong the life of LED bulbs installed in recessed light fixtures. Only CanCoverIt has the correct load-bearing shape to keep its form even after years of insulation pressing down on it.

CanCoverIt is the easiest to install which means the job will take less time while delivering you superior results. You will notice increased comfort, lower bills and over time with LED bulbs see their lifespan maximized.

Before you do any other home upgrade, rule your attic to create a perfect platform for all your other upgrade desires.

You deserve a comfortable and efficient home, and you can get it in just one afternoon with CanCoverIt.

CanCoverIt for every metal fixture in your ceiling.

Halo Effect For Home Upgrades

It is a great intention to try getting better scores and metrics to help homeowners, but so many people are trying to approach this angle that it is now starting to overwhelm homeowners. 

A metric is less impactful than using a ‘halo effect’ around a few fast, tangible upgrades. Look to Apple’s success getting people into an ecosystem of products using one key product.

Over here at CanCoverIt we see our solution as an ideal halo effect product - do it first and then approach other specifics later.

It’s low-cost/high-impact so it will win over the homeowner to more advanced concerns later, but delivers the majority result immediately so that even if they never go further it’s still a win at scale.

We really need to get people retrofitting their homes NOW, and I want to propose that we try: 

“Homeowner, we can fix your attic for savings on your heating/cooling and increased comfort, it will take one afternoon.’ 

vs the current:

‘Homeowner, first we will get a metric reading which will define the performance of your home which will then allow you to choose a range of options congruent with the metric... etc etc’ 

One of those messages will resonate, the other has not historically and still isn’t today.

The great news is that we can still get homeowners interested in technical specifics and metrics, but let’s do it after they have actually upgraded the structure of their home.

How does CanCoverIt fit into my budget if I'm looking to upgrade my home? Full interview: https://youtu.be/GSgSeDc6cLw

I hope this message resonates with you because, dropping the business persona for a moment, I’m a 27 year old guy who is terrified of how we just keep on adding air conditioner load and heating use to the residential grid while it remains unchanged in efficiency. There is a lot of talk around metrics for testing homes, and great work going on in new construction, but the elephant in the room is that existing homes are the massive majority of the problem, and they aren't getting replaced any time soon!


But I’ve become much more optimistic the more I see homeowners do attic upgrades with CanCoverIt right away. They're cutting their HVAC use in half with just an afternoon of CanCoverIt and some standard blown insulation. This is huge, and it will actually happen because it's low-cost and easy to implement.

I have been shown through working with CanCoverIt that it is possible to get everyone in North America to upgrade their homes nearly overnight, but it has to be a no-brainer or we’ll lose them in the hustle of their daily lives as we have been losing them for the last few decades!

So if you are going to measure someone's house, make sure you fix it too before you leave. 

One afternoon of CanCoverIt upgrade makes a huge difference in each homeowner's life, now let's scale it up!

Characteristics Of A Successful Home Performance Upgrade

As a case study Comfort Advisors Energy Upgrades (CAEU) completed an upgrade on a 1300 square foot Costa Mesa home, that has a crawlspace, which was built in 1961.  The home had the original furnace in a closet, asbestos ducts and a small amount of insulation in the attic that had a lot of rat feces in it.

Our first measure was to have the asbestos ducts removed by AQHI, a company that is licensed to remove, transport and dispose of hazardous material.  

Then we removed the insulation, vacuumed and sanitized the attic.  After cleaning the attic, our HVAC crew came in and installed a new Bryant furnace with a manual fan, R6 Mylar flexible ducts and a NEST Learning Thermostat.  A deck was created in the attic to access the furnace and we also built a catwalk beyond the furnace, so that the homeowner could maintain a radio antenna that is mounted in the attic. 

This same day we had an electrician come in and install two continuous ventilation fans, which constantly exhaust air from the house and are a combustion safety precaution.  Installation of a Carbon Monoxide alarm is another safety measure that we install during each upgrade.

The next stage was sealing the attic floor.  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

CAEU is one of the few companies on the West Coast that utilizes CanCoverIts to cover recessed cans.  Rather than use sheet metal around the cans that do not limit access to attic air (dirty, hot or cold) we use an insulated cover that reduces recessed can leakage, yet still allows them to be insulated and ventilated safely.

Duct leakage is a crucial part of each upgrade we complete.  In more than 2 years of testing ducts, the average leakage that we have found in homes is approximately 32%.  Please note that asbestos ducts are not supposed to be pressure tested so we utilized an Energy Upgrade California approved vintage default table.  We came up with the data below as we tested the duct leakage:

  • 28% duct leakage – Asbestos ducts, as prescribed by Energy Upgrade CA vintage default table
  • 8.5% duct leakage – After new Mylar flexible ducts were installed
  • 2.5% duct leakage – After sealing of boots that are cut into the walls or ceiling

By lowering the building leakage, minimizing the duct leakage and blowing in R38 of cellulose insulation, this Costa Mesa homeowner will have a very comfortable residence 365 days a year.  They also now have a furnace fan to circulate the air in the home as desired, especially on days that are unusually hot.

Please feel free to contact us if you have any questions regarding this home performance upgrade or to schedule an appointment to see how you can make your home more comfortable and energy efficient.

The Common Sense Upgrade Approach to Climate Change

The bill has come due for our excessive use of the planet's resources. We need to become much more efficient and in tune with natural cycles if we are to continue thriving on the planet Earth. We face a Big Problem - so big that it is terrifying and thus causes some to feel overwhelmed and deny. 

Luckily, the Big Problem is actually just networks of smaller inefficiencies and shortcomings - we can get to work solving the Big Problem today!

First we need to understand with a clear head and see the truth, a big part of which is: 

Building energy use, from homes to commercial, is a growing crisis.


In just the US alone buildings already use 39% of all national energy produced and emit over 2,236,000 metric tons of CO2 per year.

Three-quarters of all homes in the United States have air conditioners. Air conditioners use about 6% of all the electricity produced in the United States, at an annual cost of about $29 billion to homeowners. As a result, roughly 117 million metric tons of carbon dioxide are released into the air each year. - https://energy.gov/energysaver/air-conditioning

This inefficiency gets worse when the weather gets extreme, and extremes are the new norm.

Suburban homes are extremely energy inefficient. The Berkley CoolMaps project reveals the scope of the suburban problem.

While urban areas are improving, the suburban zones were considered trickier to solve.

The current suburban home has a big problem in its can-lights and other metal penetrations. If you have not covered your can-lights with CanCoverIt then heating/cooling your house is like trying to fill your bathtub up while leaving the drain open!

Air-tight is not the core issue, radiant energy transfer through metal is what's costing you!


Thankfully new homes do not feature this dynamic as strongly, although we still see many builders out there in the field over-focusing on air-sealing and not paying enough attention to metal conductance to their customers' detriment (that's a topic for another post!)

Let's just assume all new homes are perfectly efficient. They still won't arrive in time to fix the problem.

In the US we build around 575,000 homes a year, which means that in the next five years we will build 2,875,000 new more efficient homes. Great! But there are over 130,000,000 existing homes. Oh... at current rates it would take over 200 years to replace all existing homes... 

Replacing old homes won't scale. We need to make the old homes more efficienc!

Replacing old homes won't scale. We need to make the old homes more efficienc!

So we say don't focus on replacing everything. Instead make what's already here better - instead try a Common Sense Upgrade approach. This means start where it's most impactful: your attic! 

There's a diminishing return to extensive home upgrades, so let's focus on doing the 80-90% improvement work TODAY which will get homes ready to accept more advanced upgrades later down the line. An 80-90% improvement NOW is what is needed, then we can get to 100% tomorrow, and even keep going to energy production

Installing CanCoverIt combined with insulation improvements is the most impactful / lowest cost path to a better energy future in North America.

Other approaches to fixing the energy leakage caused by metal ceiling fixtures all fail when they're needed most: the extreme days. Even if you live in a moderate climate, that one heat spell or cold snap could cost you months worth of previous savings, and not to mention will tax the local infrastructure and cause you personal discomfort. Only CanCoverIt is designed to work in the most extreme conditions because it has taken every element of air and energy transfer into account.

Extreme weather increases the trouble that your can-lights cause, and only CanCoverIt can effectively solve the problem.

CanCoverIt solves all can-light energy transfer - reduces bills in half and improves comfort!

CanCoverIt can reduce A/C cycles by more than half in almost every building. 

Being off is as good as being gone.

This means that the 110 million A/C units installed today functionally get reduced to just 50 million units!

By installing CanCoverIt on every metal ceiling penetration we can eliminate millions of tons of pollution and save billions of dollars - NOW!

And CanCoverIt improves the operating efficiency of fixtures too – without CanCoverIt, LED bulbs installed in can-light fixtures are starting to fail in just a few years, even months, due to the intense thermal fluctuations of attic conditions. Protect your valuable LED bulbs, fans and speakers with CanCoverIt and save big on heating/cooling bills while reducing your carbon footprint dramatically! 

Plus, widespread installation of CanCoverIt minimizes the need for flex alert behavior changes since peoples' homes no longer bleed energy. This will free our minds up from that obligation so that public officials can start new programs for raising awareness on other ways of saving, like reducing plastic use. 

The Common Sense Upgrade approach is to improve the structure of every building at minimal cost and scale it out to everyone, not try to hammer away at behavior change and costly 'perfect envelopes'. Over the last six years we have seen our customers install CanCoverIt to solve their problems, then get interested in other upgrades.

Deliver results with a low-cost/high-return upgrade then get buy-in for more expensive upgrades, not the other way around!

CanCoverIt is the keystone element in a network of common sense upgrades - a smart thermostat will report the issue and try to adjust temperature but it cannot change your home's actual structure so the energy will still leak. CanCoverIt improves the actual structure, which lets other upgrades work much better!

Our big climate problems are actually millions of little problems - fix enough little problems and the big one goes away!

Start with your own home, get your neighbors to join in and we can start a movement to improve your local world and improve the whole world in the process!
