Avery Dennison® SP e-Lite i Interior is a spectral selective window film. It's a bit of a magician. It rejects solar energy by reducing invisible light on both ends of the visible light spectrum (infrared and UV). Surprisingly, however, it still lets in lots of natural daylight.
SP e-Lite i has two main purposes and advantages over regular dual reflective window films: interior brightness and exterior appearance. By allowing greater visible light transmission than other window tint, this film keeps interior spaces bright and airy. Sunlight has been shown to improve mood and help regulate circadian rhythms. It also reduces the need electric lighting. These features are beneficial for residential buildings such houses, apartments, and dormitories. Extra light can also be advantageous in schools, classrooms, libraries, and offices.
SP e-Lite i window film does not discernibly alter the exterior appearance of windows. It doesn't produce a mirror effect. This characteristic is great for heritage and historic buildings. No tacky combination of modern-looking glass with centuries' old architecture. SP e-Lite i reduces solar heat gain while keeping the original appearance of the building. Rejecting solar heat is particularly helpful when old buildings have outdated, undersized, or non-existent cooling systems.
This spectrally selective window film blocks 99% of UV light. This slows the fading process of fabrics, paint, and other delicate items. This material also has low reflectivity, which preserves visibility to the outside both day and night.
This is an interior window film. It applies to the interior side of windows. It is ideal for retrofits and remodels.
