The terms nanotechnology and nano-particle are used quite frequently in today’s discussions of advanced window film technology. Nanotechnology is a term meaning anything that is 100 nanometers or less in size. Many different substances can be broken down to nano-sized particles. In relation to window film, these particles are dispersed in one of the polymer coatings to control solar energy.


Nanotechnology is one of the premier sciences in the world today. From biotech to aerospace, the implementation of nanotechnology has exponentially advanced many industries including window film. In the window film world, we refer to some of these particle as nano-ceramics.

The advanced nano-ceramic coatings that Madico® offers selectively interfere with light. Being selective, the coating allows the visible light to transmit while blocking the infrared light. Each of these components have an impact on heat gain.


Madico scientists can engineer nanoparticles or nanoceramics (which measure 1 billionth of a meter) to identify and absorb vast amounts of infrared energy, 99% or greater of the ultraviolet light, and varying degrees of visible light. It’s why we can refer to films such as our Black Pearl® Nano-Ceramic as spectrally selective.
