This cutting-edge innovation features an advanced IR nano-particle coating, which not only enhances optical clarity but also provides an all-encompassing shield against heat, glare, and damaging UV and IR rays. The exceptional solar control and color stability of our non-metal Excel IRP set it apart from other IR blocking films, while its impeccable aesthetics further elevate its superiority. As with all ASWF products, it comes with a lifetime factory-backed warranty that guarantees its "color stable" performance.
