Twin-Wall Sheets can be processed by the same methods as those used for solid materials.

SMONA® Twin-wall sheets offer the following features:

• Higher physical strength due to variable web spacing (54 and 108 mm)
• Construction of larger tanks (5 m³ and more) possible without steel reinforcement
• Custom specification of outer skin thicknesses (6 and 8 mm)
• Number of webs can be varied according to requirements (10 or 19 webs/m)

Design-specific advantages:

• Rectangular tanks possible without steel reinforcement
• Lighter weight than solid material due to cavities
• Excellent sound insulation (DIN EN ISO 140-3)
• High rigidity and strength High break resistance
• Many different fields of application
• Low heat transfer coefficients (k-value/U-value) based on ISO 8301, EN 1946-3

Plastic-specific advantages:

• High thermal insulation
• Good electrical insulation
• Good slip properties
• High wear resistance
• High chemical resistance
• Low water absorption
• Resistant to microorganisms
• Excellent processing capability
