Kepler Rowland Heights, CA

Kepler builds its reputation on the film itself: the materials, the coatings and the consistency of every roll that leaves the factory. That work sits behind a range used by professional tinters in many markets, from automotive nano-ceramic film to architectural products for glazing in homes and workplaces. The aim is straightforward. Give installers film they can stand behind, and give their customers glass that is more comfortable to live with.

Choosing a tinter can be harder than choosing a film. Online advertising makes every operator look equally experienced, and the finish you actually get depends on the skill of the person cutting and fitting the material. Kepler's role is to supply the film; installation is handled by independent businesses. Ask a local tinter whether they carry Kepler film or can get it. If you are approaching a shop yourself, it is worth asking whether they can source and install Kepler film for the job you have in mind.

Window film has moved a long way from simple dyed sheets. Kepler's focus has stayed on manufacturing quality, because a film that holds its color, clarity and adhesion is what makes an installation worth having years later. That principle runs through the automotive ranges and the architectural products alike, and it is the reason installers keep the brand on their shelves. Ask a local tinter whether they carry Kepler film or can get it.
