Built On Film Quality
Kepler is a window film manufacturer first, and everything else follows from that. The ranges, the technical data and the tools we give dealers all exist so that an installer can specify the right product and explain it plainly to the customer. Film is chosen by measurement rather than by name: visible light transmission describes how much light passes through the glass, while solar heat performance is a separate property, which is why the only fair comparison is the same film in the same shade. That is the standard we build the range around, in Massachusetts and anywhere else Kepler film is fitted.
