Dark facades

SolReflex – dark colors on External Thermal Insulation Composite Systems

External thermal insulation composite systems play an important role in the energy optimization of buildings because they provide high efficiency at relatively low cost. In the past, dark colors have often been a problem. Our solution: SolReflex.

The problem

A lot of sun, especially during the long days of summer, causes surface heat build-up temperatures of more than 70°C. This can cause cracks in the plaster system or deform insulation material.

The solution

TSR-formulated and standard facade paints are applied the same way.

TSR-formulated and standard facade paints are applied the same way. With SolReflex, Brillux offers a system in which surface heat is reduced thanks to special formulas. This provides more flexibility in the design of external thermal insulation composite systems when using dark colors.

Lightness reference value?

The lightness reference value represents the lightness of a body color as seen by the human eye in relation to pure white (lightness reference value 100) and deep black (lightness reference value 0). However, the human eye can only see electromagnetic radiation in a wavelength range between 400 to 700 nm (nanometers). This range determines the different perception of body colors, with the range between 500 and 600 nm the most important for lightness perception.

Advantages of SolReflex at a glance

  • reduces heat build-up of insulated facade surfaces
  • the simple and safe solution for external thermal insulation composite systems makes using colors with lightness reference values of 20 and less possible thanks to TSR formula colors
  • provides maximum flexibility for the color design of external thermal insulation composite systems
  • protects the reinforcement and top plaster layer against excessive temperatures   
  • no expensive special solutions (i.e. double fabric layer, special reinforcement materials and insulation boards) required – normally, two paint coats are sufficient

TSR values?

TSR stands for Total Solar Reflectance. The values range from 0 to 100 (as in the case of the lightness reference value), with a high value representing good reflection and a low value representing poorer reflection.
