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.

@sunspot42 3 года назад

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.

@neverwinsthegame 3 года назад

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.

@travellingslim 2 года назад

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.

@trogdorstrngbd 2 года назад

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.

@quintessenceSL 3 года назад

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.

@jakobrosenqvist4691 3 года назад

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.

@heelgraag 3 года назад

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

@jasonlassen7599 3 года назад

Nikdo is correct. This insulation is used in my Yurt and 0 sound insulation is generous. Heating and cooling insulation properties are good.

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.

@straitcomfortsystems170 3 года назад

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.

@rabuanmantine5137 2 года назад

Good idea

@DavidPaulNewtonScott 2 года назад

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.

@joshuacheung6518 2 года назад

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.

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.

@user-vp1sc7tt4m 3 года назад

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.

@skeletonboxers7336 2 года назад

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.

@Kedarsangam 2 года назад

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.

@sagittarius_ 3 года назад

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.

@adrianjas284 2 года назад

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!

@classifiedinformation6353 2 года назад

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

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.

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.

@callum_boss 2 года назад

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.

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.

@ernestbywater411 2 года назад

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.

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 literally can just staple or glue it to the walls and be done with it.

@DonTruman 4 месяца назад

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.

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.

@garethbaus5471 2 года назад

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.

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.

Can you compare the performance to blow insulation in an attic? I am looking to improve my attic insulation for ice damming. Thx

Hi Belinda, can you do a comparison between vented and sealed crawlspaces. I've seen lots of advertisements that describe large energy savings when a crawlspace is sealed and turned into a conditioned space with insulated walls, but with the floor insulation removed. Thanks!

Serious question. Wouldn't the best thermal break under a slab be under gravel with a material similar to this over compressed foam board?

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'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.

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.

@jimurrata6785 3 года назад

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.

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.

Will this out perform the sale thickness of foam with foil face ?

Very interesting :)

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.)

@GaryYoung-eq1ph Год назад

2 questions can u put bubble wrap over another insulation? And can u use only small bubbles instead of mix bubbles?

@bobbyshaftoe 3 года назад

single use.. great point. Plastic is VERY reusable. Great points!

I've come across this material a lot in van-life build videos.

@jenniferbeveridge131 3 года назад

The DIY channel recently ran a show about a couple building an off-grid home with a "9 inch wall": instead of 2x6 studs for the exterior walls, the framer used two 2x4's with an inch of space in between them. It was described as being a "house within a house." The idea was that spray foam insulation would fill the gap in between the studs, increasing the r value of the wall. Would that actually work? And how would it affect the overall integrity of the structure?

@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.
