Gold-Sputtered Film
Gold-sputtered film uses a microscopically thin gold layer for solar control, producing a distinctive warm appearance and good heat rejection at the cost of signal transparency.
Gold-sputtered films are a niche product. The gold layer reflects infrared efficiently and resists corrosion, but the warm tonal cast and the signal attenuation make it a poor fit for modern Singapore vehicles.
Some commercial buildings have used gold-sputtered glazing for aesthetic effect. In automotive, it is essentially a legacy technology.
We do not recommend gold-sputtered films for cars in Singapore — between ERP interference and the legal VLR limits, the practical drawbacks outweigh the spectral benefits.
