To what does the term "retrofit" refer in the context of reflective film?

The term "retrofit" in the context of reflective film specifically refers to the installation of the film on existing surfaces. This practice involves adding or modifying components to enhance functionality or performance without the need for a complete overhaul or replacement of the original structures. In essence, retrofitting allows for upgrades and improvements, such as increased energy efficiency or glare reduction, by applying new materials or technologies to the existing systems.

In the case of reflective film, this could involve applying a special film to existing windows. The film serves to reflect heat and light, improving energy conservation and comfort in a building. This approach saves both time and resources compared to complete replacements, making it a practical solution in many situations.
