PRODUCT DESCRIPTION
STADIP SILENCE® is a laminated safety glass with acoustic performance. It consists of at least two glass sheets bonded together with one or more Polyvinyl Butyral (PVB) interlayers including a special acoustic PVB interlayer (PVB Silence), providing excellent insulation against noise.

BENEFITS & APPLICATIONS
Acoustic comfort in buildings is crucial for undisturbed work, relaxation and living. Controlling glazing acoustic performance improves health, productivity and concentration. STADIP SILENCE® is designed to reduce intrusive sounds and create calm, safe environments.

• The special acoustic PVB interlayer filters sound waves around the critical frequency of glass to effectively reduce intrusive sounds.
• When combined with standard PVB, STADIP SILENCE® provides the standard safety performance of laminated glass and protection against UV to reduce bleaching effects from sunlight.
• Can be used as monolithic glass or integrated in double or triple glazed units to reach higher levels of sound insulation in residential or non-residential buildings.
• Suitable for both internal and external use.
• Typical applications: glass facades and windows near noisy areas (streets, airports), overhead glazing (reduces impact noise from rain and hail), internal partitions in offices or meeting rooms (single pane variants can reduce sound up to 47 dB depending on thickness).

APPEARANCE
STADIP SILENCE® has the same appearance expected from standard laminated glass. Once transformed, PVB and acoustic PVB are perfectly transparent and essentially invisible to the naked eye and do not alter the appearance of the product, especially when coatings are applied.

TECHNICAL INFORMATION
RANGE
Available in standard jumbo size (PLF) comprising:

• 2 glass sheets with thicknesses from 2 mm to 12 mm (substrates can be coated)
• Up to 6 interlayers (totaling 2.28 mm when applicable) with at least one acoustic PVB interlayer

STADIP SILENCE® is proposed on common Saint-Gobain Glass substrates (e.g., PLANICLEAR®, DIAMANT®, ORAÉ®) and can be combined with other glass functionalities such as solar control, thermal insulation or self-cleaning coatings.

PROCESSING
STADIP SILENCE® can be cut and processed in the same way as regular laminated glass. The acoustic PVB interlayer may be combined with one or more standard PVB interlayers to provide enhanced mechanical properties comparable to other laminated safety glass ranges.

PERFORMANCE
The following acoustic performance examples are representative Rw, C and Ctr values for STADIP SILENCE® configurations (labels indicate product designation and nominal thickness):
Header: Product | Rw (dB) | C (dB) | Ctr (dB) | Nominal thickness
STADIP SILENCE® 22.1 | 33 dB | -1 dB | -3 dB | 5 mm
STADIP SILENCE® 33.2 | 35 dB | 0 dB | -3 dB | 7 mm
STADIP SILENCE® 44.2 | 37 dB | -1 dB | -3 dB | 9 mm
STADIP SILENCE® 66.2 | 39 dB | 0 dB | -2 dB | 13 mm
STADIP SILENCE® 88.2 | 41 dB | -1 dB | -3 dB | 17 mm
STADIP SILENCE® 1010.2 | 42 dB | 0 dB | -2 dB | 21 mm

Rw, C and Ctr explanations:

• Rw (Weighted Sound Reduction Index): assesses reduction of noise transmitted through glazing; higher values indicate better sound insulation.
• C and Ctr: spectrum adaptation terms adjusting Rw for specific noise sources; Ctr accounts for low-frequency noise (e.g., road traffic) and is typically negative, reducing the effective insulation value when relevant.

COMPLIANCE
STADIP SILENCE® complies with EN 14449 (Glass in building) and is CE marked where applicable.
