ASWF Commercial Window Films come with a 15-year warranty backed by the manufacturer, which covers bubbling, blistering, peeling, and de-laminating from the glass and will maintain its appearance for years to come.ASWF Ceramic Window Film is completely dye-free and metal-free. Being dye-free, it will provide the most natural hue and lookout instead of a “blue shift” caused by dyed films. Equally important, the color and shade of the ASWF Films are built throughout the film rather than the top layer as with competitors’ films, resulting in the dye’s fading, scratching, or changing colors over time.
