What is the greatest limitation of retrofitted reflective film?

Retrofitted reflective film is designed to improve energy efficiency by reducing heat gain and glare from sunlight, but it has certain limitations, with one of the greatest being its susceptibility to scratching. This limitation can significantly impact the durability and aesthetic appearance of the film after installation. Scratches may not only affect the visual clarity but can also lead to diminished performance in terms of energy efficiency and UV reduction.

While the reflective film can enhance energy efficiency and is often cost-effective to install, these benefits do not negate the potential for damage caused by scratches. Similarly, while some reflective films can provide a degree of UV protection, they do not offer complete UV protection compared to other more robust window treatments. Thus, understanding this limitation allows contractors and homeowners to make informed decisions about installation, maintenance, and expectations for the longevity of the material.
