Heat insulation: effectively block sunlight infrared radiation and shielding ultraviolet rays, the temperature difference before and after construction is 3℃~8℃. Thermal insulation: Nano-materials for indoor hot air infrared radiation high reflection, blocking heat through the glass conduction heat. Transparency: The visible light transmittance is about 80%, which is not only transparent, but also does not hinder the daylighting field. Environmental protection: For water-based System products, environmental protection, tasteless, harmless. Durability: Film uniformity and integrity, strong adhesion, high hardness, excellent durability.
