Heat insulation for wavelengths above 1000nm + building insulation film with excellent weather resistance: the optimal solution is a multi-layer Magnetron Nano Ceramic Film. This means using ceramic compounds such as titanium nitride (TiN) to replace easily oxidized metals like silver/aluminum, achieving metal-like IR reflectivity through multi-layer structure via magnetron sputtering, while maintaining the chemical inertness of ceramics.
Why is it not a ‘pure heat-absorbing ceramic tint,’ but a more advanced architectural window film?
Many people think of heat-absorbing when they hear ‘ceramic film’ — that’s a single-layer coated nano ceramic particle film, which indeed isn’t sufficient for wavelengths over 1000 nm. But magnetron-sputtered multilayer ceramic reflective films are a different matter:
TiN (titanium nitride) is a golden ceramic conductor with optical properties close to metals, capable of reflecting and blocking near-infrared, rather than simply absorbing heat.
Through multilayer stacking design, effective IR blocking can be extended to over 2000 nm.
Since it is a ceramic compound, it does not oxidize, corrode, or block signals, and its weather resistance far exceeds that of metal films.
Weather resistance: Since it is 100% metal-free, it does not oxidize or corrode; it has extremely strong resistance to salt spray and acid-base corrosion, with a service life of over 10 years.
