Ahead Film presents a range of high-performance window films designed to significantly enhance energy efficiency, comfort, and sustainability in buildings. These ultra-thin films, measuring just 50µm in thickness, boast a 100% UV cut and up to 99% IR cut, actively contributing to Sustainable Development Goals. A core feature is their complete UV-A (up to 400nm) blocking capability, achieving a 0.0% UV transmittance rate. This effectively prevents skin damage, fading of interior furnishings, and deterioration of the film itself. Furthermore, the films provide substantial heat insulation by broadly cutting infrared radiation across the 780nm-2500nm range, reducing solar heat gain by up to 40%. This ensures a noticeable cooling effect, leading to significant energy savings, with potential CO2 emission reductions of approximately 5% and annual utility cost savings comparable to or exceeding Low-E double glazing. Manufactured from polyester resin and acrylic-coated polyethylene terephthalate resin film, Ahead Films are certified as non-combustible (NM-5484) and comply with JIS A 5759 (2016) standards. Key models like TSM-87C offer an 88% visible light transmittance, 0.0% UV transmittance, and 0.3% IR transmittance, with a shading coefficient of 0.79. The TSM-80C model provides 81% visible light transmittance and 3.7% IR transmittance, with a shading coefficient of 0.65, offering enhanced heat shielding. These films are versatile, suitable for various applications including energy saving, safety, and shading, providing superior thermal performance and comprehensive protection against solar radiation.
