Spectral selective inside window film

Pleolit® SP Window Films – Redefining Spectral Selectivity

Pleolit® SP window films represent a breakthrough in advanced glazing technology, offering a new benchmark in spectral selectivity. Engineered for exceptional performance, these films deliver outstanding solar energy rejection while maintaining high levels of visible light transmission—far exceeding the expectations of even the most demanding installers.

Thanks to their ultra-low solar absorption rate, Pleolit® SP films can be safely installed on the interior side of even the most complex glazing types, including double, laminated, low-e, and triple-pane units. This flexibility makes them an ideal solution for both retrofit and new-build applications.

One of their key advantages is their ability to maintain a bright and naturally lit interior. Because the reduction in visible light is so minimal, it's virtually imperceptible—ensuring that indoor spaces remain vibrant and comfortable. As a result, there’s no increase in reliance on artificial lighting, helping to keep energy consumption and electricity costs in check.

Combining cutting-edge technology with subtle aesthetics, Pleolit® SP films offer a smart, sustainable solution for enhancing both building performance and occupant comfort.
