A Dutch company called PXA Nederland sent me these samples of Isobooster insulation which might be the most fun and innovative product I’ve received. It consists of 3 repeating layers. The first is low density polyethylene or LDPE bubble wrap with small air cushions. The second has large air cushions and the third is a polyester or PET film treated with evaporated aluminum.
Let’s look at the three modes of heat transfer.
- Conduction is the flow of heat through solids. Materials with high density conduct heat faster than materials with low density because air is a poor conductor.
- Convection is the flow of heat through a gas or liquid. Heat warms air molecules which expand, become less dense and rise.
- Radiation is the transfer of heat through infrared rays which is a band on the electromagnetic spectrum between visible light and microwaves.
Isobooster insulation addresses radiation with multiple layers of aluminum foil, and addresses conduction with multiple layers of bubble wrap.
The reflected infrared radiation vibrates water molecules and evaporates them. This makes the air in the wall cavity and in interior spaces drier and it decreases the relative humidity. This constant layer of hot, dry, rising air always moves along the surface of the reflective foil - a phenomenon called the Coanda effect. Dry air insulates twice as well as humid air, leading to a healthier environment, and preventing mold.
ADVANTAGES
Installation is very simple. It can be cut to size with scissors or a box cutter. It’s attached to wood studs with staples or capped nails. All the seams must be taped up. It doesn’t release any harmful fibers or dust, it doesn’t cause any skin or airway irritation and it doesn’t give off any toxic fumes. Since it’s flexible, It can be easily wrapped around pipes and outlets in stud bays. It’s great for both renovations and new projects.
It is 8 times lighter than conventional insulation materials, so transportation and labor costs are cheaper. It is maintenance free and DIY friendly. It’s especially useful on houseboats where every kilo or pound counts. It can also be used on the remodel of old homes and buildings with space constraints. It’s very versatile. It can be on walls, floors, basements, ceilings and roofs, both inside and outside.
It is environmentally friendly. The manufacturing of LDPE and PET film is clean and efficient, it has low CO2 emissions, and it doesn’t create much waste or harmful substances. It is also not an energy intensive process like traditional insulation. Isobooster not only reduces the energy consumption of a building, it is also 100% recyclable. It also has no thermal drift or loss of R value over time. It is also insect and rodent repellent.
DISADVANTAGES
Its R value is 2.4 per inch, comparable to fiberglass. However, if you’ve watched my R-value video, you know that the testing method favors fibrous insulation. If you look at the actual thermal resistance due to reflection of radiation, rather than conduction, it probably performs much better.
I was disappointed with the material’s fire resistance. It singed initially, but after prolonged exposure to the flame, it ignited. It costs 13.77 euros per m2 or 1.55 dollar per square foot. It’s even more expensive than rockwool which is $1 per sq ft. Most importantly, this is a vapor barrier with a very low perm rating. In older buildings that don’t have an HVAC system, you need to vent the cavity to allow water vapor to escape.

I’m 64 years old and when I grow up, I want to be as smart as Belinda
You have to be born Indian😜
I'm not sure I'll be grown up by 64, it might never happen 😁
Man I love this channel. She is always on the cutting edge of architecture and building materials. One of the most underrated channels on CZcams.
This is what I love about the internet. Exchanging of ideas and good conversations about the subject at hand. Thanks for sharing your experience.
Hard AF right now
The fashion argument was the strongest. I’m sold.
And if you don't like the house, you can ship it away. No need to worry about wrapping.
I added the Home Depot product to my new home during construction 10 years ago for additional radiant and thermal purposes, lowest energy bills in neighborhood 🤗🤗
I will only install this when I am comfortable with the neighborhood kids coming over to constantly pop my walls.
I keed, I keed.
I did post a comment about a guy building a ICF home - totally. Walls, floors, roof, the works. Jesse Muller.
**it doubles as high fashun**
I laughed really hard xD
"plastic is an incredible human invention."
hells yes. thank you!
It's weird that it's so thin, but I've used an emergency blanket before. Those are super thin, but reflective and VERY warm.
and entertaining... you can pop the air cells all night long
Someone recently told me he used emergency blankets to insulate his attic
I saw a homeless guy sleeping in a city park, in Anchorage Alaska, that had wrapped himself up in a sheet of bubble wrap and was sleeping like a baby all snug and cozy. It was winter. And I remember thinking *hmmm, that'd make an interesting insulation for a remote hunting cabin. It rolls up tight, is light and easy to transport on a four-wheeler or small bush plane where space and especially weight is critical. I was considering a remote piece of property at the time and I remember how excited I was, like I had thought of something nobody else had. The cabin never happened and I had forgotten about it, til now. Anyway, cheers from Alaska.
They should fill the bubbles with Nitrogen, so that it acts as an extinguisher in case the house catches fire.
There is a brand that does. I use it when insulation wrapping duct work. I can't remember the name but by itself has a listed R value of 6 when wrapped over R-8 unbacked insulation it totals R-16.
Good idea
A waste of time it will diffuse away over time although polyethylene is extremely low permeability it is not zero permeability. If it is really worrying just cover it in a layer of plaster or drywall. Though that would be a weight problem for boats.
I doubt it would be enough to matter even if it didn't diffuse
Or CO2. That will have the same effect but also capture heat better. It is a larger molecule so it might diffuse slower as well.
Belinda, informative and interesting video as always. Thanks for being upfront about the manufacturer requesting the video and supplying the product. I hope to see you do a video on spray foam insulation soon.
I love your take on plastic being eco-friendly. It's up to us to find the best use for the materials that are available to us!
Last year during our heatwave I bought some of that foil-coated bubble wrap you featured for a moment in the video. My metal window frames were reaching 140° and the windows were letting a ton of heat and light into the room. Just a thin layer of that stuff blocked most of the heat radiating off the window. It’s surprisingly effective. I mounted it to the window using Command strips, so it can be easily removed and replaced whenever needed.
This looks like a 21st century product. Hope the building industry is paying attention. They are so slow to evolve into better ways of doing the same old thing. 👍
Belinda we missed you!
You can encapsulate it (mostly) to improve its fire rating in standard installation scenarios (between studs, etc.). Even spraying with a flame retardant would help.
I'm curious about its sound transmission compared to other materials. An overlooked aspect of insulation is sound deadening, especially in urban areas.
For sound proofing I belive a fibrous material will preform much better, this is just a bunch of thin membranes that won't really absorb sound very much at all.
For sound reduction you can best use a double layer of sound reducing plasterbord with a special kit in between them. this works better than any minieral wool
Nikdo is correct. This insulation is used in my Yurt and 0 sound insulation is generous. Heating and cooling insulation properties are good.
WHAT?
I had this idea a few months ago, they could potentially make shipment much cheaper by inflating the film on site. Machines that can inflate packing film exist and are inexpensive.
Seems like that would introduce too much complexity for average consumers, and for larger projects with contractors, the cost of labor and waste due to improper inflating would eat away at any shipping savings.
I would guess that those machines only work for very-large-cell or continuous-interior inflatables. The dense sealing pattern of small-cell bubble wrap is likely to be a major hurdle.
I'm starting a van conversion and I have been looking for a lightweight product like this to insulate with. I will keep you informed if I use it . Thank you.
I am converting a bus, I think this is the way to go for our build.
George, please update us, if you did this. Would be very interesting to understand more about it.
@@albaugh1818
Did you use it, or choose something else?
Make sure you leave a small air gap between the wall of the van and the rolled stuff like this at home depo. It helps keep the damp out. We also use it for our window shades. Keep the silver on one side and we made the other side black for night use.
Another winning video, Belinda! Thank you!
We use bubble wrap for some twenty years as insulation in winter. We have a plastic skylight in our second bathroom that looks out in our garage, which is seven meter high and in winter we where losing too much heat thru that skylight and for that reason I put several layers of bubble wrap on it. Works very well and it is the same wrap for all these years, so it lives a long time.
Loved your final scene. We all love to pop bubble wrap 🤩
Thank you. I am in the middle of conditioned loft project. I bought some bubble wrap insulation for encasing awkward hip purlins, reflecting on the material properties, so this has reinforced my decision.
Another great video Belinda!
Belinda Carr , The rolls of bubble insulation you show in your video is actually used by a lot of Van lifers and road trip campers. My friend and I shared a huge roll and made window covers for both of our cars windows for our last road trip vacation. It was really nice how it kept the cars interior heat way down. We’d put the window shades up when we left in the morning and it was still cool when we came back in the afternoon. We left one side silver and made the other side black.
I absolutely agree and commend you for your view on plastic. I also think it is a great material that has been abused and misused. We should not stop the use of it but control the use of it.
I built a workshop in Florida with a layer of Reflectix stretched over the rafters, 1x2 nailed over to the rafters over the Reflectix and a galvanized metal roof over that to create a vented roof. I was amazed at the difference in heat gain that it made. It needed very little air conditioning. It made me a big fan of reflective insulation.
Very much looking forward to a video on spray foams! They’ve fascinated me as the combination air sealer, vapor barrier, and insulator.
I used 1/4" foil bubble wrap on the ceiling of my steel cargo trailer. It worked very well to deter thermal heat from transferring to the inside space. Half way through installing the insulation, I noticed that uncovered areas were emitting intense heat compared with the covered areas. Very impressed with the thermal resistance of the foil bubble insulation.
John
As always a really good and ambitious video. Thanks Belinda!
I have thought about this since a few years but unfortunately came to the conclusion that it must be further developed to be usable for an architect or a builder. Besides the poor fire properties, the main problem is the big molecular size of plastic material in the bubbles. This causes the much smaller air molecules to leak out and bubbles to collapse. My tests has shown that after 3-5 years the bubbles are almost empty amd unusable for isolation. This is also why all tires on cars and bicycles regularly must be refilled and pumped again. Rubber molecules cant stop the small air molecules from slowly leaking out.
But I think this concept might have a great potential if further developed.
Air is going to leak out in order to equalize the pressure between the bubble and the atmosphere.
I know that some brands of bubble wrap have lower pressure than others (you know those types of bubble wrap that are unsatisfying to pop? it's because they have low air pressure)
Bending the insulation around corners, putting other heavy materials on top of it, the air inside heating up and expanding, are all going to increase the pressure inside the bubble and speed up leaking.
I can see how even if you had very low pressure in the bubbles at manufacture, in application you are going to have problems.
I hope they can figure out a way to make it more air-tight because it looks like an awesome concept!
I've been waiting for this episode - very informative and excellent, as always. I'm sure the fire retardant issues will be sorted, and overtime the prices will drop.
I wouldn't be surprised if some people made their own DIY versions to keep the costs down.
This product is a perfect solution to the issues I have seen in older 40-80's houses especially in the craw space or foundation space areas with inferior insulation or vapor barrier under the first floor. I lived in many such houses and this product would have been such an easy install/solution to issues we faced. I once considered rockwool batts with netting to support the batts in one house but moved on. If this Bubble wrap & foil home insulation product was available I would have installed it. I held off with the rockwall because I thought it was just not going to prevent the crawlspace air from moving up through the house and may have created a mold issue.
Always so thoroughly explained.
Thanks
I used a similar product under the steel roof of my shed, it works very good for keeping heat out in summer and the inside of the roof doesn't condensate when it gets frosty in winter.
The DIY camping community has used Refletex for as long as it's been out. I've insulated everything from my camp chairs to water bottles with it in order to save weight on the trail
Oh WOW! I found a new use for all my popped bubble-wrap. I would love doing this type of insulation.
leave the air in!!
Belinda Carr for president! I will vote for you. Love this channel and the common sense it brings to construction issues. I guarantee this way of looking at things would solve most of the world's problems.
Yay welcome back!
Excellent well researched presentation. Thank you for your valuable contribution.
I have concerns of the product lasting 70 years. That is a lot of heat cycles, and I'd say the climate variance in the US is quite different than Denmark. At least with conventional products about the worst that happens over time is slumping, and that is more installation error than product. At least in my experience.
To contribute, I've experience of standard bubble wrap surviving the elements of the UK in external use for twenty years in use on commercial greenhouses. In that time and unprotected there was deterioration, but it was still functional and not in need of replacement. From the same roll kept in an open barn (roof, but only walled on two sides) there was no discernible difference to new bubble wrap.
There's an awful lot of difference between 20 and 70 years, so I'm not arguing with you, just inputting my experience.
@@callum_boss Thanks for the information. I think it has value as your example would be more on the worst case scenario side.
I have a similar experience to Callum. 11 years ago, we built a small greenhouse in our backyard and sandwiched bubble wrap between two layers of corrugated polycarbonate roofing to make the roof more insulated. Our yard is in a high elevation desert and gets intense heat, UV, and cold; 50° temperature differences between day and night are fairly common. The bubbles still look just fine and haven't deteriorated. I thought the UV would destroy it after a few years but it still looks surprisingly good.
I have used the "double bubble" products you can get from venders that is about 3/8" thick that has a foil layer on one side and white layer on the other side, and that stuff is ridiculously tough. Seriously durable in my experience using it for a variety of purposes.
I continually learn new things on this channel, things that I probably don't seek out to know about. However, the best thing about it is that I derive a lot of enjoyment while learning new things. These things are what I consider dry and not interesting, but Belinda makes them interesting. She should be a teacher, not an engineer. What do you do for a living, Belinda? I wish other channels can be this educational and enjoyable, yet practical.
Whare have you been all my life? This is knowledge that humans need to know. All your stuff.
It will be interesting to know the longevity of the PE material in the super-high heat of an attic. Only time will answer that question.
Seems like a great idea in concept. I have considered it since the early 1980's. I have seen similar products at home and garden shows for nearly as long. However, I have always stopped when I considered the flammability of the materials commonly used in this.
I live in the desert and I was using reflective sheeting to cover my windows during the summer months. Our parks management prohibited me from using reflectives on my windows so I now use bubble wrap sheeting! Not only does it work just as well if not better, I don't have to experience dark rooms anymore for the summer months! Great video! All the best :)
Your park management what ?
Incredible !

Great video.
This insulation solution is great.
Kids would be eager to help (pop.. I mean install) this stuff too!
i love your videos and your transparency so much. its been so refreshing to come across your channel, ive definitely been recommending your videos left and right!
the carbon emissions from plastic are counter intuitively, really low! you're right there, its just they take forever to degrade, why not put it into a house that should (ideally) last for a long time! thats why i still support plastic, but only for certain uses, and realistically, recycling plastic isnt as easy as its made out to be, and only very specific kinds can be recycled. the petroleum industry was so successful on putting the burden of us to deal with the responsibility of recycling and reusing and "reducing" when in fact theyre the ones profiting off of using cheap packaging materials that wont break down.
Thank you for this! I was considering the bubble insulation (the one from Home Depot) for my shed and I was on the fence about it. Now that I have more information I can make a better decision.
This one is really intriguing!
It is cool but moisture build up seems like a big issue.
This seems like a good product I love your channel, I'm building a 500sqft home and I'm starting to make it as close to passive as I can afford this may be a good option to replace the vapor barrier plus provide a little more R-value with less chance of thermal drift.
having multiple vapor barriers in a wall assembly is a mold problem waiting to happen. if i ever used this i would make sure its inside the insulation for a cold climate and really well sealed. i had only seen the one layer type before. thanks Belinda
My dad Is a pre engineered steel builder (sentry builders) in AZ. He use to use a foil backed bubble wrap type of insulation in his buildings for those that only wanted a low r value insulation.
Thinking about putting in insulation in the roof of my garage, this might be the product for me. Theres not much room in the rafters and I don't want to handle toxic/dangerous/irritating materials
Lay it across the rafters not with them. Then Tape it off. No More heat loss out thru the roof. Use the 4 foot wide with a staple hammer. Staple one side to the rafter than smack the ADB SO IT HAS AN INCH OF SLACK THEN STAPLE THE OTHER SIDE KEEP GOING ACROSS THE RAFTERS.
4:08 THANK YOU! Finally, someone who agrees with me!
Single-use plastics are the problem, not plastic in general.
I learned from a physicist in the 70s who once worked for NASA, that aluminum reflects 94% of the infrared energy. They built satellites with this idea, multiple layers of aluminum foil. The key was that the layers had to be isolated from touching each other. The first layer has 94% reflection. In the second layer, 94% of the escaped 6%, etc... The heat of the electronics kept the interior warm enough to continuously work in the cold space where no heat exists. I lined the interior of my boat with foam and aluminum for the winters of AK. The foam also provided for flotation too.
I don't know if things are done the same way in the USA as they are done here in Australia. However, here it's common for builders to lay a thick plastic sheet down as a moisture barrier when they prepare and area for a cement slab to be poured. At one construction site I passed a few times on the way to work I saw them laying double sheets of bubble wrap on top of the moisture barrier plastic, so I stopped and asked about it. The builder said the bubble wrap was a cheap way to greatly reduce heat loss through the cement slab into the ground, and thus keep the house warmer in winter. That was a good idea as they were building ins a snow prone area.
One recent winter, it was very cold. I put bubble wrap on the glass in my windows for insulation. It helped.
This product is poorly designed by someone who doesn't understand the basics of radiative energy transfer. The reflective aluminum layer is sandwiched between two or more layers of optically clear but thermally (IR) opaque polymer layers (the 'bubble wrap'). When used within a wall cavity as thermal barrier, 100% of radiative heat transfer is in the IR, which is absorbed by the polymer layers. This leaves no thermal energy to be 'reflected' back to the source (interior or the exterior). If the exterior surfaces of the bubble wrap are finished with the aluminum layers, the whole thing will act as a good conductive. convective radiative barrier."'Reflectix" brand insulation better since both exterior surfaces are aluminum and act as a good IR reflector.
This is so good. Agree 100%
Considering I have more issues keeping the heat out in summer than keeping it in in winter, I'll check this out for my south facing roof!
In the Netherlands these kinds of materials have been available for years. I have used a multi foil myself years ago in my little motorboat. works perfect. It is als often used as a second layer of insulatien, in combination with a miniral wool. this is needed in order to get the high Thermal resistance rating that the law requires without an 50 cm thick wall
I love your videos my friend! Thank you! :D
If their is an air gap with drainage between it and the outside of the wall I would probably put a thin layer of something like this under the siding but on the far side of the air gap from the walls. That way it doesn't trap moisture in the walls, and can still reflect radiative heat supplementing a high R-value layer of insulation.
I had 4" fiberglass insulation on my water heater. Took it off and wrapped 2 layers of the mylar bubble wrap from home Depot.
I ment to rewrap over it with the fiberglass, but didn't get around to it.
The 2 layer mylar bubble wrap reduced my energy use on my water heater by a minimum 3 to 4x!
When I get around to it, I plan on fixing the hole in the outside door to the water closet, and insulating the interior of the walls with more of that. I literally can just staple or glue it to the walls and be done with it.
wow, what's the thickness of the HDPE on the bubble wrap? as long as they dont pop, right
Interesting product and detailed commentary. I've installed and removed rockwool (ecowool) in Australia in one of my lives as a labourer and can see many advantages in the handling of this product. Trying to shift public sentiment would be the biggest challenge as you say, especially in such a conservative country like my own.
Have watched most of your videos. Appreciate your work.
Am looking for a way to keep my existing attic cooler in Summer, having seen how hot it gets up there (by use of a remote thermometer. I did put in wool insulation on the ceiling areas, but I figure by insulating the roof rafters that will help even more. Found "Double Reflective Insulation Radiant Barrier" at Home Depot. A 4' x 100' roll is $166, which is $.332/sq ft. Photos show it being stapled to the surface of the rafters, which would make it easy to install. Seems this would create an air pocket between the roof and the foil, which would provide some insulation to the attic. Next challenge (from watching your videos) is making sure there aren't problems with water or fire. I.e., water vapor can evaporate, roof leaks drain in a way that doesn't lead to disaster, and fires aren't made worse. I presume its highly fire resistant so that isn't an issue. As for drainage, maybe it's best to leave some holes and gaps in it. While that defeats the goal of insulation somewhat, I expect it would be minor.
Good analysis
There are applications where this product really shines. Under concrete slab, RV's and tiny homes. Also retrofit or supplemental applications where a vapor barrier that insulates is a real time/money saver.
Interesting suggestion, _under slab_ , as more and more states are banning XPS (or all blown styrene) building products.
Lack of rigidity may be both a plus and a minus. Surely it will want to float, where a board is simply ballasted by the concrete.
I imagine it could be difficult in this application because of ruptures from rebar and installers needing to walk on it, but we definitely need an alternative insulation product.
Sticking literal bubble wrap on windows as a bit of extra insulation is somewhat common in South Korea. Energy pricing is often pretty aggressively 'tiered', so folks tend to be really interested in keeping on that lowest tier of usage and every little bit helps.
Adding in a mylar/mylar-like layer is clever. Good for this company.
BTW: Some museums have had the opposite problem with humidity during the pandemic. No visitors so the air getting too dry for the HVAC system (designed for having visitors) to handle.
This is the type of insulation used in modern yurts. We live in a 30 foot yurt with 10 foot walls and this insulation works great. Blue Ridge Yurts.
I love your content. In this comparison, no mention of sound insulation is made. Buildings in urban areas and multifamily buildings would benefit from sound insulation. I would enjoy hearing your take on the subject.
That stuff's been available in N. America for a while. It's good for making window shades to protect the interiors of vehicles, boats, and aircraft. (Easy to cut and doesn't create nasty fibres.)
Seems like a good thing for the roof of my house in Portugal. It would also be good for use as a layer in solar heaters so long as it is protected by say rock wool.
On that subject I would like to hear your opinions on pop or beer can solar heaters. On the subject of recycling plastic I am a strong believer in either burning it for energy or converting it to fuel oil.
Recycling requires that some new plastic be added making an inferior product and if you think about it that is a mathematically absurd proposition tending to infinity.
Really love your channel and all the videos on insulation. Have you done any investigating on vacuum insulated panels as home insulation?
I've come across this material a lot in van-life build videos.
Excellent! thank you!
You're funny! Thanks for your research and presentation. Oh and high fashion suggestions too!
It's funny, I've used this stuff to insulate the new bath on the underside (I'm from the Netherlands). It's easy to work with, no dangerous particles are released when cutting it and you just tape it on there.
IN australia, the foil backed insulations was installed in part , nation wide as part of bungled rebate programme. Aswell as the mould issues mentioned, 2 workers died from electrocution as a result of exposed wires in a roof. Another issue to consider here.
ive put this isolation on to the lower part of my windows since the cold streams low and heat goes high.. if you have cold windows in your hallways doublewrap it.. i use magnet tape to remove it in the summer.. 5 years and still works great, also alot less burning gas in the winter..
I love your channel so much! So, you think it’s a suitable material for insulating a bus? I would love to see you do a video on the best insulators for bus and van builds.
I'm surprised to hear it's not commonly used. IIRC we foil-wrapped the house we built (10-15 yrs ago), the product looked similar but was bonded together as a continuous single layer. It was just part of the overall insulation tho, I think we also had fibre-batts in there too.
"Doubles as high fashion," lol.
Awesome video.
This is interesting content!
So, new sub. 😊
What about foil faced fiberglass, how does it compare, particularly in the north.
I used this in my garden cabin 3 years ago, just made it myself, it's just bubble wrap & foil, very cheap, but I wouldn't use this in a larger building due to it's lack of fire resistance.
I think the biggest drawback for me with this product would be the low fire resistance. Up here in Canada, we get cold winters with lots of snow, which means lots of heaters running, which in turn causes a higher risk of fire. I'd be interested to see if doubling up the thickness of this product would increase its thermal insulation value, or if that would be necessary at all. Most homes are built with 2x4 or 2x6 construction, so it being only just over 2" thick might make for larger air gaps in wall cavities.
I've heard of people already using just bubble wrap to insulate their windows.
I always wondered if bubble wrap and aluminum would be a good insulator. Seems to be :)
SOLD! Going to put into my shed. Always feel like i just left my chemistry class! Is there a place you can buy this in the US? can't seem to find anything.
in older buildings it some towns of Japan they freeze bubble wrap onto windows in winter for added insulation. and when it warms up it slides right off
Popping your insulation for stress relief.
I love your content! Do you happen to have any tips on how to insulate an existing home (2 years old) in arizona? I'm wondering how to go about the outside insulation. What do you do with the outside stucco? Do you have to remove it? I'm talking about trying to reach insulation of an earth home or adobe house but with a conventionally built home.
I’ve learned more from this channel than reading an architectural book
@belinda Carr
long-awaited, Thank you.
it's a great product. we are using a double-sided ai bubble sheet in India it does not cath fire easily as you have shown in the Video because plastic is protected by pure aluminium.
its fire resistance is not proof (please don't compare it with Rockwool or e.tc :P )
cheap and best insulation available in India (batter than a traditional radiant barrier )
as you said it's a complete vapour barrier it may case in mould e.t.c same problem we also faced.
Need a video that shows R value and cost for all types of insulation you have featured. This would help people make better choices more easily.
That's really funny, I was in an insulation shop because I'm doing a van conversion and the guy there recommended some aluminum faced bubble wrap as insulation and I thought he was a clown and a con man... but apparently there's something to this.
Very interesting :)
