According to its manufacturers, only two or three coats of this paint will be enough on a wall, ceiling, facade or roof to achieve a useful thermal insulation for a lifetime. And do not be afraid, we can change the color, since even if we paint over it, it does not lose properties.
How does it work
The basis of this material is an ecological white water-based paint. Ceramic microspheres are added to this, something like "a kind of microscopic hollow marbles, which form a layer of air in the paint itself," according to one manufacturer. This layer of air is precisely the one that insulates from the cold and heat outside. This quality of the material also prevents water condensation, which helps prevent dampness and mold. And the good news is that not only does it help save energy, it also makes your home cool down more slowly in winter and heat up more slowly in summer, leading to more consistent temperatures.
As demonstrated by a trial at the University of Zaragoza, Spain, using thermal paint can lead to a change of up to 3.5ºC in the ambient temperature of a room.
Why is it ecological?
Thermal paint is composed only of organic and environmentally friendly substances. Therefore, it is not toxic and can be used in children's bedrooms.
Where can we use it?
This paint can be used in homes and in industry, both on walls, such as ceilings, facades, roofs ... For roofs, there are waterproofing variables that also serve surfaces exposed to the sun, since precisely the roofs are one of the parts of the house that accumulate more heat. And while your roof is more waterproof, the house is better insulated.
Why does it remove moisture?
Thermal paint prevents water from condensing on the wall if the indoor and outdoor temperatures are very different. This, in expert language, is called a thermal bridge break. With this, no humidity due to condensation or the dreaded mold appears.
And if we already have mold, it can be removed: it will be enough to carry out a small cleaning with diluted bleach and then apply the paint. Then the insulation itself will prevent the new appearance of mold on walls and ceilings.
Thermal paint is not much more expensive than a good quality conventional paint. But its advantage is that we will amortize your investment, since in one or two years we will have saved on heating and air conditioning. On the other hand, it is durable: for a lifetime, its manufacturers say. And you can paint on it as many times as you want.
It is painted, by the way, like any other paint, with a roller or brush. And in addition to isolating from heat and cold, it reduces the noise we receive from outside. And it does not burn or ignite.
