Some time ago, research by AltroConsumo, She appeared a technical comparison between the 4 best thermal paints on the market.
THE 4 products were tested on masonry and equal environments and found the corresponding benefits in terms of effective insulation than promised by manufacturer.
The results? Pointless to anticipate, What I can say straight away is that in Exchange for promises of egregious and miraculous performance, the results were mediocre and extremely far from expectations.
Promise energy savings interesting and absence of condensation the thermal bridge by insulating the inside or outside walls of Home with a highly insulating layer.
For this are called heat-insulating paints (or even thermal coatings) and containing ceramic microspheres, or nanoparticles or glass dispersed on a support resin.
According to the theory of producers, These particles would create a layer of air between the wall and the paint, that would make it possible to reduce heat loss, to reduce thermal bridges and in practice to compensate the surface temperature of the wall, lowering it in summer and increasing in winter.
Given the declared characteristics, many have wondered if similar products can be a viable alternative to thermal insulation for energy saving (because they would be easier to implement and more economical).
Well I have to say that, by testing, It is shown that such products do not reach nowhere near the promises outlined in the label.
Also, it was found that, compared to a regular water-based paint, the best thermal coatings, He manages to raise the average temperature of the wall of less than one degree.
In the test applied products on uninsulated walls with high temperature difference between indoors and outdoors, in order to better highlight the effects that termopitture can ensure.
The results that we list below, show that the producers have gone too far with their promises and that these are not even remotely be found in reality.
Analyzing the results carefully proves without any doubt that the surface temperature is only marginally influenced by these miraculous paints.
AtriaThermika – internal heat insulating
Average cost: 91 Euro per 5 litres of product (approximately 12 euros per square meter)
Product description: Paint for interior use based on resins acrylic mixed with ceramic beads.
Statements: on the label it States a saving of 20% and in the data sheet shows a strong reduction of the heat exchange compared with surfaces treated with traditional painting.
Test results: the tests do not confirm these results. Despite being the best among the audited, the product is able to increase the average surface temperature of only 0.74°(C).
Balogun – heat insulating paint
Average cost: 50 Euro per 5 litres of product (approximately 5 euros per square meter)
Product description: Paints based on synthetic resins in emulsion and hollow glass microspheres.
Statements: a label, it promises the creation of a "barrier effect” that would be capable of inhibiting the thermal variations, the transmission of noise (sound-absorbing effect) while also reducing the formation of condensation and mold (contains "biocides").
Test results: the outcome of the evidence totally repudiates these slogans and thermal enhancement offering is practically insignificant or nil.
ThermoSchield – Exterior
Average cost: 124 Euro per 5 litres of product (approximately 8 euros per square meter)
Product description: Exterior painting, Acrylic based, with hollow Ceramic microspheres.
Statements: on the label is attributed to the product even the same properties of the skin to ensure thermal equilibrium and promises an improvement of thermal insulation up to 40%.
Test results: lack of theoretical studies and practical tests that support alleged qualities. His ability to raise the average temperature of an uninsulated wall is quite modest and manages to increase on average by 0,44 °(C).
Surfapore – Thermodry Exterior Paint
Average cost: 207 Euro per 10 litres of product (approximately 3,45 euros per square meter)
Product description: Acrylic paint for exteriors based on nanotechnology.
Statements: on the label it States a high energy reflection capacity and good resistance to heat loss, qualities that would ensure a "significant” energy saving.
Test results: Squesto last product has been shown to be able to increase the temperature of a wall not isolated of only 0.43°(C). Obviously too little to boast a significant saving in economic terms.
In the light of, although Igrodry not belong to the category of paints nor thermal paint and has never declared thermal insulation properties (as it is more effective in damp walls especially if badly polluted by sali minerals), We can say that these results so mediocre you can overcome very easily simply by applying to any pareter 2 Sun hands of IgroDry with the aim of restoring the natural state of perspiration building.
Should not be forgotten that in fact is still the masonry It is the only true and primary protection system, insulation and thermal storage in a building.
Keep efficient, breathable and dry the perimeter masonry, has proven repeatedly to be the best way to significant energy savings (much of the thermal paintings), offering a good clean air and perfect protection against mold, fungi and bacteria in the home environment ’.
Seeing is believing, IgroDry, Although it has slightly higher costs (compared with the thermal paints), These would be offset by the best healing and insulation effect obtained, the easiest application, less invasiveness, no solvent odor in the House, no need to Dodge furniture and furnishings as transparent, odorless and colorless. Not coincidentally is also the best anti-mold market today.

Update of 31 September 2015
Following the protest of a producer of thermal paintings (I expose you below in green), It seems to be considered unreliable As it is written by other consumption article just exposed.
Understanding that today it seems that the quality is dictated only by those in possession of certifications without looking at the effectiveness of the products (in this case the thermal paintings), We stick to what was decided in legal and publish that adjustment.
the allego ANIT-Manual, which lists the ISO reference for non-CE marked, as in the case of the paintings.
A thirteen page can see the reference to ISO 1934:2000, with whom we SurfaPaint TD Certificate (the allego)
The manual outlines how some materials sold for not having miraculous certifications, but with calculations made by the same distributors, have no value.
Other Consumption, It has proved, far from being trustworthy, Since it took a material with Thermo-reflection characteristics and wanted to make calculations by conduction, measuring then the surface temperatures, where our product has no function… There is still only one answer.. SurfaPaint is the only product certified, and could hardly see other certified materials with this standard that would demonstrate the effectiveness of a product.
The certification allows us to ask for anyone grinding, even in good faith, republish the news millantatoria.
Remaining in a non line controversy, It would be useful if in his blog, publish what the manual ANIT writes, and that SurfaPaint is certified for its efficiency and recognized by applicable law.
This is independent information and technically questionable.
