Choosing the Right Interlayer: PVB, SGP, EVA, and PU in Laminated Glass

Laminated glass is essential for modern construction, offering safety, durability, and versatility. The choice of interlayer—PVB, SGP, EVA, or PU—defines its performance.

Here’s a look at these interlayers and their benefits:

• PVB (Polyvinyl Butyral)

Applications: Windows, doors, automotive windshields.

Benefits:

Safety: Holds glass fragments together.

UV Protection: Blocks harmful UV rays.

Sound Insulation: Reduces noise.

Versatility: Available in various thicknesses and tints.

• SGP (SentryGlas Plus)

Applications: Structural applications, balustrades, skylights.

Benefits:

Strength: Five times stronger than PVB.

Durability: Resistant to delamination.

Safety: Maintains integrity after impact.

Clarity: High optical clarity.

• EVA (Ethylene Vinyl Acetate)

Applications: Outdoor environments, solar panels, decorative glass.

Benefits:

Moisture Resistance: Ideal for exterior use.

Thermal Stability: Performs well under high temperatures.

Adhesion: Strong bonding with various glass types.

Versatility: Compatible with decorative materials.

• PU (Polyurethane)

Applications: Security glazing, automotive, aerospace.

Benefits:

Impact Resistance: Superior protection.

Elasticity: Withstands deformation.

Adhesion: Strong bonding with glass.

Clarity: Maintains optical clarity.
