Thermoreflective paints and plasters combine the usual protective characteristics of decorative coatings with the peculiarities provided by special fillers and specific additives, which increase the Solar Reflectance Index (SRI). This index is a parameter that measures the ability of a material to reflect incident solar energy. It is a standardized unit of measure that combines the values of solar reflectance (SR) with those of thermal emissivity (ε) of the specific material.
Thermoreflective paints can be used on various types of surfaces, such as exterior walls, roofs, floors, and even vehicles. These paints are designed to have low emissivity and low heat absorbance, meaning they reflect most of the solar radiation instead of absorbing it. This has several advantages. Firstly, they reduce heat transfer through the treated surface, helping to keep indoor environments cooler.
This can be particularly useful during periods of intense heat, reducing the need to use cooling systems and, consequently, energy costs. Additionally, thermoreflective paints can also help improve the energy efficiency of buildings. By reducing heat transfer through exterior walls and the roof, they can help maintain a more stable temperature inside the building, reducing the need to use heating systems during colder periods.
It is important to note that the effectiveness of thermoreflective paints depends on various factors, such as the type of surface treated, the orientation of the surface relative to the sun, and local climatic conditions. In the thermoreflective finishes produced by AZICHEM, identified with the suffix THERM, the following are present:
- siloxane-based finishes: PROTECH SIL,
- mineral finishes with potassium silicates: SANAXIL.
To provide a wide range of material solutions, the range includes:
- paints, indicated with the letter P,
- plasters, indicated with the letter I.
Therefore, regarding paints, the products in the range are:
- PROTECH SIL P THERM
- SANAXIL P THERM
While, regarding plasters, the products in the range are:
- PROTECH SIL I THERM
- SANAXIL I THERM
There is also a primer with water-repellent and thermoreflective functions:
- PROTECH FIX AC THERM
All finishes have excellent water vapor permeability values and low water absorption values, in addition to being pigmented with stable pigments, predominantly of mineral nature.
