Glass and infrared light: protection against infrared radiation

18/01/2023

 

 

Nowadays, glass is designed to perform multiple functions rather than just protect against the elements.

One of them is protection against infrared radiation, ensuring significant comfort in terms of light and heat.

In this case we speak of coated glass, which is used to limit radiation from the sun in passenger compartments by calibrating the amount of incoming infrared radiation.

Through this very effective technology we can actually control the amount of infrared radiation that filters through the glass. Let's take a look at the main phases of this manufacturing process.

 

Coating, one of the main glass design phases

 

One of the most interesting new developments applied to glass in line with the latest technological advances is undoubtedly protection against infrared radiation.

That's because glass that isn’t susceptible to radiation-induced coloration or discoloration seems a contradiction in terms, and yet it is possible.

How? By specifically coating the surface with deposits of metal. Not just any metal, however. Depending on its physical and chemical characteristics, the metal employed can give the glass different physical properties.

 

Why coating is the right choice for glass intended to protect against infrared radiation

 

The most interesting feature of coating is its range of applications.

Glass designed to protect against infrared radiation has two very specific purposes:

-                     The first is to significantly reduce the electromagnetic emissions of infrared radiation, granting greater control over the temperature inside the passenger compartment and, therefore, greater comfort.

-                     The second concerns the metal deposited. With suitable electrical connectors, this may be used as a resistor, thus enabling the coating to perform a glass de-fogging or de-icing function.

In short, a particularly creative and innovative use, enhanced by the fact that we do not produce standard films or interlayers for the automotive industry; instead, we design custom coatings delivering optimal performance.
