You have probably thought about how to improve the thermal insulation of your home without having to carry out invasive works. Keeping the walls well insulated is key to optimising both the interior temperature and the energy used in the air conditioning of the home. For these cases, an innovative and efficient solution is thermal paintThis relatively recent technology helps to increase insulation on a surface thanks to its unique properties.
Below, we'll explore in depth the features, special properties of thermal paint, how to apply it, and the benefits it offers. Read on to find out if this solution is right for your home.
Thermal paint characteristics
Thermal paint is a revolutionary element in the world of insulation and energy saving. The most interesting thing is that does not require modifying the wall material to improve insulation. This means that you can apply this paint on any surface without having to make significant structural reforms.
A well-insulated home helps protect us from changes in outside temperature. This means that it will help us to retain heat in winter and to keep cool in summer. Understanding how thermal bridges work is essential here: they are the areas where heat or cold enters or leaves more easily. Thermal paint acts by breaking these thermal bridges thanks to its special composition.
Made from ceramic microspheres, these tiny particles create an air chamber when dry, thus forming an insulating layer that minimises heat transfer. Although the paint is usually white, it is possible to apply a layer of decorative paint without losing the insulating properties.
It is recommended to apply between 2 and 3 layers of this paint to ensure optimal and long-lasting insulation. In addition, you will not lose the thermal properties if you decide to place a decorative layer on top, which adds an aesthetic advantage combined with its functionality.
Special properties
For homes that suffer from insulation problems, thermal paint is a effective and accessible solution. This product not only offers better insulation, but also reduces energy usage. In many cases, energy savings can be up to 40% on heating and air conditioning. Furthermore, by reducing the use of air conditioning systems, the environmental impact is reduced.
Among its special properties is its ability to prevent the appearance of moisture on the walls. This is especially useful in old buildings or those where pipes generate moisture in the walls. Thermal paint acts by blocking condensation, preventing the appearance of moisture and associated problems such as mold and mildew.
Another highlight is that this paint has properties fire retardant, which means that in the event of contact with fire, the paint will not burn. This provides an additional layer of safety, especially in industrial environments or in areas at risk of fire.
Where can thermal paint be applied?
The versatility of thermal paint is another of its great advantages. It can be used both indoors and outdoors, adapting perfectly to any type of surface. This makes it an excellent option for homes, commercial areas and even industrial spaces.
In the case of industrial applications, is particularly sought after for its resistance to both moisture and fire, as well as for its ability to keep the surface waterproof. It is commonly used in warehouses or areas where walls are exposed to extreme environmental conditions. It is also used in roofs and coverings to improve energy efficiency.
It can even help reduce outside noise, as it helps to dampen sound waves. In cities, where traffic and other noises are a constant, this property is very useful for increasing comfort in the interior environment.
How does thermal paint work?
One of the most frequently asked questions is how a coat of paint can replace other insulation systems. The answer lies in the way ceramic microspheres compact as they dry, forming an air chamber that breaks thermal bridges.
In addition to this, thermal paint has properties refractory, which means that it reflects a large part of the heat received. In fact, it can reject up to 90% of infrared radiation and 85% of ultraviolet radiation. This is essential in hot climates, where direct solar radiation contributes significantly to the heating of interiors.
With thermal conductivity values similar to those of classic materials such as glass wool or polystyrene (around 0,05 W / mK), thermal paint can offer thermal insulation solutions comparable to these more traditional systems.
Another advantage is that this paint works bidirectionally, that is, it reflects heat in both directions. This means that in the winter months it will help you keep the heat inside, while in the summer it will prevent the outside heat from entering the home.
How much does thermal paint cost?
Price is one of the factors that generates the most interest. Thermal paint has a cost that may seem high compared to traditional paints. A litre of thermal paint costs around 25 euros a liter, depending on the manufacturer and color (white is usually cheaper).
Considering that this paint can have a performance of 0,8 to 1 liter per square meter, the cost of painting a 10 x 3 meter wall can amount to about 700 Euros, applying the recommended layers to ensure good insulation.
When calculating the cost, it is important to consider savings in heating and air conditioning, since in many cases, the product pays for itself thanks to the reduction in energy consumption.
Thermal paint is an innovative solution that offers multiple benefits in terms of insulation and energy savings. Not only does it help reduce home air conditioning costs, but it also improves indoor comfort and is an environmentally friendly option. With additional properties such as the ability to prevent the formation of humidity and its fire resistance, this paint is positioned as an excellent choice for those looking to increase the comfort, safety and energy efficiency of their homes.
