Opinion on insulating paint like Thermacote, info or poison?

[owen]

Hello,

I have heard of insulating paints with exceptional insulation properties.

Reflective insulating paint

Reflective insulating paint: an innovation in thermal insulation!

The insulating paint was developed for space use, due to its low thickness. Originally used on space shuttles, it is now on sale for individuals.

Insulating paint is used to insulate interior walls, facades and even roofs.
Insulating paint: composition

Insulating paint is a water-based acrylic paint, composed of four ceramic elements linked by different resins.

Its insulating and reflective power provides strong thermal insulation to the painted surface, since the heat is not absorbed, the conductivity of the support is no longer an important factor for insulation.

Despite its very low thickness (250 microns), the thermal insulation performance of ceramic insulating paint is equivalent to 12 cm of polyurethane or 20 cm of rock wool!

The insulating paint contains little VOC (about 20 g / L), so it is environmentally friendly.
Use of insulating paint

Insulating paint is used to insulate:

* cold rooms, air-conditioned rooms and refrigerated vehicles,
* storage tanks, silos,
* hangars and buildings housing animals,
* metal roofs.

To ensure its effectiveness, the insulating paint exists mainly in white.
Exterior insulating paint

Outside, insulating paint is suitable for thermal insulation of facades and roofs:

* in winter, it prevents heat loss;
* in summer, it isolates heat by reflecting the sun's rays;
* it is in the form of a white plaster;
* it is resistant to bad weather, mold and dirt;
* it holds well over time, without yellowing.

Interior insulating paint

The insulating paint is suitable for indoor use. It has several advantages:

* it prevents heat loss;
* it reinforces sound insulation;
* it regulates the humidity level and does not condense;
* it corresponds to the needs of an interior paint (choice of colors, absence of unpleasant odors).

Attention: The insulating paint can be applied indoors and outdoors; in this case, the wall will remain cold.
Apply insulating paint

Insulating paint is suitable for all types of support: concrete, wood, metal, PVC, etc.

Before applying insulating paint, the wall must be perfectly dry and clean. In addition, a primer must be added on porous surfaces such as concrete.

To obtain good coverage, apply two coats of insulating paint, leaving a drying time of two hours between each coat. But beware, the drying time at heart takes two to three weeks.

Insulating paint is usually applied with a spray gun, but a brush or roller can be used. The tools are cleaned with soapy water.
Reflective paint: price

Insulating paint is expensive: around € 35 per liter (for a covering power of 2,45 m² / L).

I'm having trouble finding a brand of product.

I can hardly imagine that a coat of paint is equivalent to 12 cm of EPS.

So my question is this info or intoxication?

I ask to test ...

Already, the use of the word "ceramic" is confusing: a ceramic being in principle recognized as being a heavy material, therefore conductive: only light materials, low density ... are good insulators. If the paint film is insulating and has special properties, why not, but insulate like 12cm of expanded polystyrene! They do not go with a dead hand.

Being an acrylic paint, everyone knows that it behaves like a polymer and makes a film. I have already asked. Although not one of this type, it looked like latex (Dulux for exterior). Although it attenuated the heat transfer, it was not completely insulating, I would say that it was partly, but rather "refraining" (if we consider a house as a kind of "pile" .. it ends up going elsewhere, no). Could nanotechnology have evolved so much? Should try.

In any case, if it works, it's a revolution ... yet not to be used without precautions or everywhere amha.

It is not impossible, but I can hardly see a 250µ film remaining in the pile effect of a frame. I rather see the use of this as a sealing film ... because I fear that the condensation will take off the paint itself ... Since it will necessarily seek to settle between this film and the support ... with time...

By cons it is absolutely excluded that it can "Reinforce sound insulation". The people who wrote this are not serious, or do not know their job.

At most, can we speak of "phonic correction»

Because of its weight, a light thermal insulator, cannot offer sound insulation against vibrations caused by sound, which will only be stopped by heavy, high density materials! It's not for nothing, in my corner, if the rock groups rehearse in atomic shelters ...

I also note this sentence, curious in many respects:

Attention: The insulating paint can be applied indoors and outdoors; in this case, the wall will remain cold.

Finally, why are they hiding the mark ...?

It smells like intoxication full nose ... I haven't even read the cited article but it smells like the argument of thin insulators worse !!!

So read this topic on thin insulation tests: heating-insulation / objective-testing-of-thin-thermo-reflector-insulators-t3069.html

Corresponding article: https://www.econologie.com/isolants-min ... isolation/

The only thing that a paint COULD be insulating with is electricity or electromagnetic waves (charged with flakes of aluminum or other metal to make a farraday cage) ... it can also be conductive and heat (ca we've been talking about it for years but I still don't know if it has been approved) but at what cost in terms of ambient electromagnetic pollution?

[dedeleco]

NASA may be using it because the space is empty and insulating and only infrared reflective walls are missing, which this painting may do is declared to be reflective, but with air you only gain a little on infrared, and nothing on the thermal conductivity of the air which destroys the vacuum insulation used by NASA !!

Same misleading argument and therefore pure misleading scam referring to NASA §!
!!

It's amazing how long this type of false scientific scam can last !!

[Did67]

Always the same thing !

Heat, in a solid, is transmitted by conduction and by radiation.

That it can act on radiation (like thin insulators), it is possible.

In space (vacuum), this is the only way energy is transmitted (no conduction / convection). So yes, thin insulators and possible "IR reflective" paints are very effective ...

In a house, radiation exists, but so does conduction ...

So agree with dedéléco and Christophe.

[Christophe]

In a house, radiation exists, but so does conduction ...

Yes for the walls but for the whole house, air convection (especially that close to the walls) also exists!

In the subject of forums on thin insulators it has been shown that they are "approximately effective" only if surrounded by 2 theoretically motionless air spaces (tight = no convection = "vacuum", see NASA).

In this case, at best, there is an equivalence of 2 to 3 times their thickness in conventional insulation (but the 2 air layers of 2 cm = +4 cm so in the end we have the same footprint see more than one conventional insulation with equivalent thermal resistance). See summary below ...

Source: Thermal Performance of Thin Reflective Insulations by the BBRI (the Belgian French-speaking equivalent of the CSTB)

Summary: https://www.econologie.com/isolants-min ... isolation/

The total measured thermal resistance of each product associated with two 20 mm thick non-ventilated air layers varies from 1,0 to 1,7 m².K / W (equivalent to 4 to 6.8 cm of 0.04 lambda insulation ) depending on the type of product and the direction of the heat flow passing through it. (...) "

Our conclusion on thin insulators

Under the conditions of the BBRI study, an optimally installed thin insulation has, at best, a thermal resistance of 1.7 m².K / W. This thermal resistance corresponds to a standard insulation thickness (lambda = 0.04) of 6.8 cm, or 68 mm, therefore very far from the 200 mm announced and the air knives must be perfectly formed. It is also very far from the thermal recommendations of RT2005 which requires a thermal resistance of 6 to 6.5 for inhabited roofs!

In conclusion, if the performance of thin insulators alone is insufficient, even with 2 air knives, these can appear as an interesting solution in addition (and only in addition) to a conventional insulator. In 2010, thin insulation alone could not constitute an insulation with acceptable performance in our latitudes.

So thin insulators must be limited to additional insulation with a conventional insulator since as you say, they only intervene for the part of the radiation.

However, radiation is a minority in domestic heat losses except near heat sources ...

So placing thin insulation between the wall and the radiators is a rich idea (but a simple aluminum foil will do almost as much ...)

To return to insulating painting, it would therefore be necessary to do the same (2 immobile blades) to obtain a "minimum" result in terms of insulation ... can you imagine the site?

In any case, offering paint that insulates like 12 cm of wool is untrue. What does the police?

ps: I clicked and copied / pasted the article in the 1st message. Indeed it is anything ... we had seen right without reading

It's not a scam:

http://specoating.com/fr/supertherm/Sup ... Europe.pdf

Surely not as effective as 12 cm of polyurethane but does very well to repel the heat of the sun therefore a complement to the insulation not to be used as sole insulator!

[Christophe]

There is a scam as soon as you promise something that is impossible to keep, and the 12 cm it is at least in thermal insulation "winter".

The page you are quoting is serious and only talks about solar radiation in summer:

Typical uses
As a one-coat insulation system:

* on exterior and interior substrates (roofs and walls) to reduce energy costs from cooling or heating and increase comfort
* on refrigerated containers, mobile homes, coaches and railroad cars to protect goods and reduce costs
* on HVAC systems, oil pipes and tanks, storage systems and ships to stop condensation and corrosion
* in grain silos to prevent mold and mildew and to increase longevity
* on animal shelters to prevent heat stress
* over RUST GRIP® on metal roofs

The "summer" case is very different (solar thermal gains = 100% of radiation and surface T ° quickly higher than in domestic heating!) And it is not the one that was mentioned in the article which talks about interior painting !

Moreover, one could very well say that a beast white paint "insulates" more than a black paint !!

[dedeleco]

does very well to repel heat from the sun

A survival blanket is also good for cheap !!

In a house, radiation exists, but so does conduction ...

Yes for the walls but for the whole house, air convection (especially that close to the walls) also exists!

Yes, yes: three lines above, I was talking about "solid"to properly situate the debate at the level of the walls, since it is about painting. You are not going to paint the air!

Otherwise, of course, okay ...
