Product Name: One-Way Perspective Flame-Retardant Thermal Insulation Window Screen Fabric Suggested Use Scenarios: Ideal for living rooms, balconies, reception rooms, and studies. Functionality: Provides effective UV protection and sunblock in summer, and windproof warmth in winter. During the day, it maintains interior brightness while making it difficult to see indoors from the outside, allowing those inside to see the exterior outlines—achieving the “one-way perspective” function, protecting home privacy. Offers all-day privacy protection, blocking outside views during the day and enhancing indoor safety at night. Principle Explanation: This fabric uses a metal coating process, where aluminum is evenly applied through vacuum sputtering technology. Using digital splitting techniques, the aluminum is transformed into fine threads. Combined with flame-retardant polyester yarn and shuttle-weaving techniques, the fabric is woven meticulously. The raw materials are precisely calculated for density and thickness to ensure the one-way perspective effect. The product reflects heat from long-wavelength infrared rays and short-wavelength ultraviolet rays, offering permanent flame resistance, thermal insulation, temperature control, and UV protection.
