Exterior

The intelligent skin for your house

Less moisture absorption, better dehumidification, higher solar input into storable substrates — even with diffuse radiation.

Section through a façade: solar energy penetrates the paint layer and is stored in the masonry.

It is not warm air that warms, but warm walls

On a façade or masonry, less moisture absorption and better dehumidification are achieved, and optimal insulating properties are restored. At the same time, a higher solar input into storable substrates is made possible, even with diffuse radiation.

The heating energy demand of a building depends on the thermal sensation of its occupants. If a person feels comfortable and at ease, the so-called feel-good temperature has been reached. The best, quickest and cheapest way to achieve this is not through warm room air, but through the radiation of warm walls.

Summer and winter, two directions

As with Thermoline Interieur, 50 % of the dry substance of the paint consists of microscopically small hollow glass particles. Through this structure, solar energy can penetrate and be stored in massive building components and materials. The result is measurable: the temperature on the inside of the building’s exterior walls increases by up to 1.5 degrees Celsius. This leads to a dry and warm wall and thus to significant savings in heating energy.

In summer, on the other hand, the reverse vapour pressure gradient takes effect. The vapour pressure increases inwards, which results in better evaporation of moisture and a cooling effect on the inside of the outer wall.

Thermally insulated façades with, for example, ETICS, are a major point of contention nowadays — not only among building physicists. They usually do not achieve the promised results or energy savings and have a strong tendency to stain and algae formation on the surface. Due to the insulation layers, solar gain into the masonry is not possible. However, the use of Thermoline Exterieur can extend the renovation intervals of these façade surfaces by up to 100 %.

Thermography: Thermoline on the left, conventional façade paint on the right

Thermographic image of a test specimen coated with Thermoline Exterieur: the stored heat is visible as a warm hue.
Thermographic image of a test specimen with conventional façade paint: the substrate is noticeably colder.

Thermographic images after the test setup with homogeneous masonry units. The right side of the two test specimens was coated with normal façade paint on normal façade plaster: the substrate absorbs very little energy and cools down very quickly. The left side was coated with Thermoline Exterieur. During the day the substrate absorbs solar energy and heat radiation much better; the heat is stored in the building structure and can be slowly released again during the night.
