Dual-Reflective Film
Dual-reflective film is engineered with two different reflectivity profiles for the exterior and interior faces, producing privacy from outside while preserving the night view from inside.
Dual-reflective films use asymmetric coatings — typically more reflective on the outside, more absorptive on the inside. The result during daytime is one-way privacy: outsiders see a reflection, occupants see through normally.
At night, the chemistry reverses subtly — interior lighting can bleed outward more than a uniform reflective film, but dual-reflective designs still preserve more interior visibility than pure mirror films.
Dual-reflective films are more common in architectural applications. Automotive use is less typical because Singapore VLR rules limit visible reflectivity.
