What is Fusun Heat-Insulating PVB Film?

• A high-performance interlayer designed for laminated glass, combining the safety and durability of PVB with advanced thermal management technology.
• Integrates selective infrared (IR) blocking and UV protection, while maintaining exceptional visible light transmittance.
• Ideal for reducing cooling loads in buildings and enhancing the efficiency and lifespan of solar panels.

• Superior Thermal Insulation: Blocks up to 70–90% of near-infrared radiation, significantly reducing heat transfer and lowering energy consumption.
• High Optical Clarity: Delivers visible light transmittance (VLT) of ≥90%, ensuring clear, natural light transmission without color distortion.
• Maximum UV Protection: Filters out ≥99% of harmful UV rays, preventing interior fading and protecting PV module components from degradation.
• Structural Safety & Durability: Maintains the industry-leading impact resistance and glass containment properties of standard PVB.
• Versatile Compatibility: Works seamlessly with annealed, heat-strengthened, and tempered glass, as well as standard lamination processes.

The Science Behind Fusun Heat-Insulating PVB

• Selective Light Transmission: Our proprietary formulation incorporates nano-sized particles (e.g., ATO/ITO) that selectively absorb and reflect infrared radiation, while allowing visible light to pass through unobstructed.
• UV Absorption: Built-in UV stabilizers convert harmful ultraviolet radiation into harmless heat, protecting both interiors and the PVB film itself.
• Diagram Placement: Embed the "Optical & Thermal Principle Diagram" here to visually explain the IR/UV blocking mechanism.

Where Fusun Heat-Insulating PVB Excels

• Architectural Glazing: Curtain walls, skylights, canopies, and windows for commercial and residential buildings.
• Solar Photovoltaics: Encapsulation for double-glass and BIPV modules, improving efficiency and durability.
• Automotive & Transportation: Windshields and side windows for enhanced passenger comfort and reduced AC load.
• Specialty Glass: Refrigerated display cases, sunrooms, and marine glazing where thermal control is critical.
