Great DIY video....on how to burn your house down! You can NOT encapsulate a non-IC recessed luminaire fixture. You trap heat which can pyrolize surrounding combustibles and ignite. The simple solution is cheap, quick and easy: replace all your cans with ICAT fixtures. These are Insulation Contact Air-Tight rated. You can pick up 6 for less than $60 at your home center. Get a licensed electrician to swap them out. These come with a weatherized trim to meet the code requirement for
Thank you for this video. We just passed the blower test for final inspection.... barely. I think that we will take down and seal around all of our can lights . We have about 100!
What about an IC box that is drafty but no access from above? (i.e. no attic above). I'm thinking about insulating with foam board and sealing the box itself from underneath, and then going to an LED bulb to reduce heat generated. Any input would be appreciated.
I have this issue in my Finished garage. Can Lights and I get some mold coming thru sheet rock...near the lights...I imagine condensation issue because of light gaps...but I have no access to above the ceiling...is there a way I can insulate of fix the issue from below...instead of above?
Its been a year and couldn't find the answer. So.... I would replace my can lightings with IC rating ones. Then you can completly cover the unit with insulation. The good things is that modern homes already have IC can lights
If you are not running LED lighting by now, it is time to switch. These older cans take to LED just fine. These non IC ratings are for in contact, the cover shown does not contact fixture what so ever and the material it is made out of will handle temps well above what the highest wattage lightbulb is capable of putting out.... Considering the amount of old 1950's dual socket light fixtures I've torn out running 100w incandescent bulbs, I wouldn't worry about these. No point on wasting money on a certification when you can just learn the science. Also if you want to bring up halogen, just because something makes a lot of heat in a tiny space doesn't mean it is a lot of heat. 25watts of heat is still 25 watts of heat. 25watts of heat in a 1" space is a lot more than in 8" of space. And just because something goes hot does mean it is dangerous, a metal acting as a heatsink being hot is doing its job, even at 125f. I'd never recommend any type of can light when thin recessed lights now exist and are nearly air tight from the get go.
If those can lights get hot and need the free area around them then how does covering them with basically air-sealed insulation stop them from overheating?
That can light cover is really easy solution but what if you don't have an attic and you can't get to it. How can you deal it from the inside of the house? Caulk? Will that catch on fire or melt causing damage?
The can light wasn’t actually cold. The IR camera falsely assigns it a cold color because of the low emissivity of the metal and glass vs the surrounding drywall. The camera was probably set to a high emissivity level. Great videos.
Good idea. In Louisiana with can lights in second floor. Summer heat is brutal, a/c is $$$. nice option. Thx. I didn't have trouble with the sound of the background music, seemed like a nice balance to me.
Good presentation, makes sense. The only issue I see is I put wood decking in the attic, over the 2x6 stringers. The can lights I bought are specicically made for this- they are about 5 3/4in tall. It appears these covers are much taller than 6in. I'd hate to have to cut 12 huge holes in the deck..
I noticed in every video I watched nobody ever talks about the type of spray foam or sealant (brand or fire/mold/water resistant). This should be an important talking point being that you are using a fire retardant cover but not fire retardant foam. Some say it's not in direct contact but the heat does come in contact with the foam/sealant when the gaps are filled. For those that care, pay attention to warranty on the foam/sealant. I found both have little to no warranty and some don't accept any responsibility even if their product fails. Some have a 1.5 year warranty. I'm a do it yourselfer that has done all my own research and found the following, DAP brand has a "Fire Block" spray foam and caulk which I find lacking in product warranty. There is 1 DAP product that I chose to use on my electrical outlets , HIGH TEMP 100% RTV SILICONE SEALANT. The 10.3 fl. oz. caulk tube has a red tip and it is hard to find, even in my major city, but I did find a place that will special order it at $9.99 a tube. Again, I'm no spokesperson but I will not go cheap when it comes to my families safety even though I'm a penny pincher.
Thank you for all your great videos! Well done. What brand(s) / type(s) of spray foam do you recommend for sealing the tenmat covers on the attic? I have a few fixtures to do
Had them come out.... There was a cost of around 250 dollars to do the energy audit... Then he gave a quote to do the job... Install insulation... Etc.... Very expensive... Had our contractor do the job for a third of the cost... But it was a good idea anyways.. Lol
Just had an energy audit done. Lots of issues. I had 2 LED lights installed that are suppose to be air tight. Well not quite. The auditor told me to spray foam around the edging. Then later am having insulation blown in and it will go over top. They are IC Rated.
You first need to seal with foam or polyurethane caulk & then insulate. Remember insulation alone does not stop air leaks. He mentions that in other videos
@dr. energy saver What can you do to insulate and recessed lights from in the room below? I have a small dining room with 6 or so can lights that need insulated but there is no attic so there is no access to the space above them. I also need to protect the lights from blown in cellulose insulation that I would like to add soon. Thanks!
+cpkelley617 For the trim ring you could use foam padding, much like for electrical outlets. For the interior of the light I would probably use foil tape (the same kind they use on ductwork.)
+crimsonsamuraiftw be careful about putting tape on the can itself, the manufacturer has put the "holes" in the can for it to "breathe" and by installing tape on the can you have "altered" it. If the can light were to catch on fire you could be held responsible or your homeowners insurance may not cover it because of this alteration to it. Here in Louisiana we can not cover the cans with the hats or boxes anymore we have to use the seal tight trim ring kits.
jjmarz1001 what you mean whats the point. The rock wall is touching the light can its an insulator and the foam is not going to go up in flames its not in direct contract and once its cured and dried its safe
I think the point is that the inverted flower pot is going to trap all of the heat and the foam is in direct contact with the heat. If it is not in direct contact, why even bother using foam. Wonder what the fire marshal thinks about these pots. Oh, and since the temperature is going to rise drastically in the pot, what happens to the overheat device for the lamp.
Very informative video highlighting a major and often overlooked problem in homes. We created a solution to easily address this very problem. Our product is a unique FSK-faced insulating can light cover that ships and stores flat, a huge advantage for bigger installs. Our Universal series has a passive venting system which lets Non-IC cans be safely and efficiently insulated with no fire hazard. There's a few brief videos on our channel about the product. Thanks for your time!
another lousy patch to a problem caused by lousy lamps and lousy workmapship.. I'd just find nice soft plastic clear bezels and cut it to exact dia of light opening and press it in. Can be done without getting into the attic.. i have about 50 such recessed lights and worried this idea will cost a fortune in material and labor. Not good Sir.. too much thermal imaging detail too.
"1926.1053(b)(21) Each employee shall use at least one hand to grasp the ladder when progressing up and/or down the ladder." I sure hope he is not sitting on the ladder. Sitting on top of the Ladder, is totally against proper ladder protocols.
That video was infuriating. Your only solution was to get in the attic and put a cardboard cover over the light? After watching 5 minutes? Pitiful. Plenty of can lights don't have attic access. What about those? What if your only access point is from below? You should have made that video 30 seconds long.

Insulation set aside,, can one at seal and caulk those leaky holes and cracks on the ceiling side?
Thank you for this video. We just passed the blower test for final inspection.... barely. I think that we will take down and seal around all of our can lights . We have about 100!
Gotta update this video for 2024 :). Good stuff.
This guy is go
Icing out gold today. Thank you for helping others

If you completely cover the fixture, How does the heat escape from the lightbulb so the thermal switch doesn't get damaged?
ANYONE WANNA ANSWER THIS???
Its been a year and couldn't find the answer. So.... I would replace my can lightings with IC rating ones. Then you can completly cover the unit with insulation. The good things is that modern homes already have IC can lights

@@halo37253 so to summarize, put in LED bulbs and it's ok to use that tenmat light cover fixture and seal? Because my 1940s house would love to know
Can light venting was for 90 to 150 watt bulbs which he mentions run at 380F. LED are 10 watt and don't need venting and the conversion is about 104F.
If those can lights get hot and need the free area around them then how does covering them with basically air-sealed insulation stop them from overheating?
What about bathroom fans ? Is there anything specific that needs to be done for those ? Great videos.
That can light cover is really easy solution but what if you don't have an attic and you can't get to it. How can you deal it from the inside of the house? Caulk? Will that catch on fire or melt causing damage?
How should I insulate an old can light in a vaulted ceiling situation?
Thanks!
The can light wasn’t actually cold. The IR camera falsely assigns it a cold color because of the low emissivity of the metal and glass vs the surrounding drywall. The camera was probably set to a high emissivity level. Great videos.
How would you tackle recessed lighting in a cathedral ceiling? I want to remove 9 fixtures from my LR and kitchen, and replace them with LED.
The Tenmat covers are actually only for making the lights IC safe, they are not an air sealing. You will need to find a way to stop air flow as well.
Does the cover cause any problems with the light , I heard that the light fixture blinks if it gets to hot
Neighbors carbon filter smell is leaking through the light fixtures. This problem just got solve! Thank you Doctor!
Why didn't you show an after shot with the thermal so we can compare the unsealed and sealed cans?
onepoket bc it's a load of crap!
because it burned the house down shortly after

I have a vaulted ceiling with no attic above, what's the altenrative
Where can I order those light covers? Also, can spray foam be sprayed to cover the entire cap?
I noticed in every video I watched nobody ever talks about the type of spray foam or sealant (brand or fire/mold/water resistant). This should be an important talking point being that you are using a fire retardant cover but not fire retardant foam.

Thank you for all your great videos! Well done. What brand(s) / type(s) of spray foam do you recommend for sealing the tenmat covers on the attic? I have a few fixtures to do
I think in this case I would go the extra step and replace the fixture with an insulation contact rated fixture. They are fairly inexpensive.
Had them come out.... There was a cost of around 250 dollars to do the energy audit... Then he gave a quote to do the job... Install insulation... Etc.... Very expensive... Had our contractor do the job for a third of the cost... But it was a good idea anyways.. Lol
The newer recessed lights do not have this huge can as I understand. Do i still need to insulate those?
Just had an energy audit done. Lots of issues. I had 2 LED lights installed that are suppose to be air tight. Well not quite. The auditor told me to spray foam around the edging. Then later am having insulation blown in and it will go over top. They are IC Rated.
You first need to seal with foam or polyurethane caulk & then insulate. Remember insulation alone does not stop air leaks. He mentions that in other videos
why cant you use some kind of gasket around a new led fixture, without going in the attic?
That's great, but what to do with recessed lights on the first floor? There's no access to outside of can..
Sir, how we can insulation the flat rcc roof?
I wish there was a company like this in Canada.
can this foam prevent from SF6 gas leak from a container?? will the foam solidifies after sometime of spraying?
How do you use that tenmat for remodel recessed lighting house?
You can also buy air tight trim rings. May not be as perfectly sealed as doing it from above, but it is MUCH easier to fix it from below.

Switch to LED lights and heat is no longer a concern.
What is the point of using the rockwool caps if you are going to seal them with highly flammable spray foam?
jjmarz1001 what you mean whats the point. The rock wall is touching the light can its an insulator and the foam is not going to go up in flames its not in direct contract and once its cured and dried its safe

What if no attic access?
Love your videos
Where can I get some of thoes rockwool bowl's?
+Chad Jones You can order them through home depot, under tenmat recessed light cover, $15/ea
They wanted $6,000+ to insulate the lower and upper attic of my Cape Cod style home with cellulose.
What is that obnoxious background noise?
Tenmat Recessed Light Cover FF135
The music (or noises) in the background make it hard to listen.
Great idea and very good video except for the background music.
Thanks Larry...
Hey, this was pretty useful. Thanks so much!
Also save your roof, moisture internal to attic will wreck your roof

Yeah but show us the results
Geeze was this long winded....
4:18 IS THE ANSWER
4:14 The answer to the video title
Please stop using background music. It's so loud, and distracting. Your video is very informative but hard to watch with the sound on...
At least lower the sound a bit.
"1926.1053(b)(21) Each employee shall use at least one hand to grasp the ladder when progressing up and/or down the ladder."
I sure hope he is not sitting on the ladder. Sitting on top of the Ladder, is totally against proper ladder protocols.
Stop the music during the video. Disruptive.
That video was infuriating. Your only solution was to get in the attic and put a cardboard cover over the light? After watching 5 minutes? Pitiful. Plenty of can lights don't have attic access. What about those? What if your only access point is from below? You should have made that video 30 seconds long.
