PVB film is the core component of laminated glass; choosing the right thickness doubles its safety. Standard thicknesses are 0.38 mm, 0.76 mm, 1.14 mm, 1.52 mm, and 2.28 mm, with a tolerance of ±0.03 mm. For architectural applications, PVB film must meet the following performance criteria: volatile organic compound content of 0.35%–0.55%, tensile strength ≥ 20 MPa, elongation at break ≥ 250%, and light transmittance ≥ 85%.
Here’s the ultimate guide to selecting PVB interlayer films for laminated glass.
PVB film is the core of laminated glass; choosing the right thickness doubles its safety! Standard thicknesses are available in five options: 0.38 mm, 0.76 mm, 1.14 mm, 1.52 mm, and 2.28 mm, with a tolerance of ±0.03 mm. For architectural PVB film, performance must meet the following specifications: volatile matter content of 0.35%–0.55%, tensile strength ≥ 20 MPa, elongation at break ≥ 250%, and light transmittance ≥ 85%.
When selecting the thickness, consider the following: the type of substrate glass, its thickness and dimensions, the application environment, and any special requirements. General architectural principles: the thicker the substrate, the larger the dimensions; the thicker the PVB. Does tempered glass deform significantly? A PVB thickness of 0.38–0.76 mm is sufficient! Bent tempered glass features a unique curvature, with a minimum PVB thickness starting at 2.28 mm.
Don’t forget special applications: for roofing and canopy glass, the PVB interlayer shall be ≥0.76 mm. The floor glass laminated structure shall have a PVB interlayer thickness of ≥0.76 mm, with a maximum thickness variation of ≤3 mm per sheet. Key quality‑control points include: no bubbles or impurities on the surface, precise thickness measurement, and successful completion of weathering‑resistance testing.
In the future, PVB film will offer high adhesion, minimal yellowing, and UV resistance—making it an excellent choice for ultra-clear glass and energy-efficient buildings! Choose the right PVB—building safety and aesthetics go hand in hand!
