Soundproof Clear Cast Acrylic Sheet – Noise Reduction Glazing
Introduction
For window manufacturers, office partition builders, and industrial safety firms, Jinan Jinbao Plastic Co., Ltd. presents our Soundproof Cast Acrylic Sheet.
While standard glass vibrates and transmits noise, our Cast Acrylic (PMMA) has a higher damping coefficient, making it an excellent Sound Barrier Material. Specifically, our 2mm to 5mm sheets are widely used as Secondary Glazing (magnetic window inserts) to block street noise without replacing existing windows. Unlike extruded acrylic, our Cast Grade offers superior density and chemical resistance, ensuring better acoustic performance and long-term optical clarity.
Key Features
Effective Noise Reduction: A 5mm sheet provides approximately 30-32 dB sound reduction (STC rating), significantly dampening traffic and voice frequencies.
Superior Optical Clarity: Achieves 94% light transmission, clearer than glass, making it invisible when installed as a window insert.
High Impact Safety: 17x stronger than glass. If impacted, it will not shatter into dangerous shards, making it safe for schools and public areas.
UV Resistant: Manufactured with 100% Virgin Mitsubishi monomer to prevent yellowing for 10+ years, even in direct sunlight.
Thermal Insulation: Acrylic insulates 20% better than glass, helping to reduce energy bills in addition to blocking noise.
Easy Fabrication: Can be laser cut, drilled, and polished without cracking (Cast grade advantage).

Applications
Secondary Glazing: Installed inside existing windows using magnetic strips to create an air gap that blocks traffic noise and drafts.
Office Partitions: Transparent barriers between desks to dampen voice transmission in open-plan offices.
Machine Enclosures: Clear guards around noisy factory equipment (CNC, conveyors) to protect workers' hearing.
Recording Studios: Vision panels and instrument shields (drum shields) where clarity and sound reflection are needed.
Why Choose JINBAO PLASTIC?
Acoustic Grade Quality: We control the casting process to ensure uniform density, which is critical for consistent sound blocking performance across the entire sheet.
Defect-Free Optics: Every sheet is inspected to be free of waves or distortions, ensuring your view remains perfect—just like glass, but quieter.
Protective Masking: We use heavy-duty masking paper or PE film to ensure the sheets arrive scratch-free and ready for laser cutting or installation.
Frequently Asked Questions (FAQ)
Q: How thick should the sheet be for soundproofing?
A: For basic noise reduction (voices), 3mm is sufficient. For traffic noise or machine guarding, we recommend 5mm to 10mm. The thicker the sheet, the more mass it has to block sound waves.
Q: Is "Cast" better than "Extruded" for sound?
A: Yes. Cast acrylic generally has a slightly denser molecular structure and less internal stress, providing better damping properties and optical clarity than extruded sheets.
Q: Can I use this outdoors as a highway barrier?
A: For highway noise barriers, you typically need 15mm to 20mm thickness with specific wind-load engineering. We manufacture these thicknesses as well—please contact us for a heavy-gauge quote.
Q: Does it scratch easily?
A: Acrylic is softer than glass. However, clean it with a microfiber cloth and soapy water (never paper towels or Windex), and it will stay clear for decades. Scratches can also be polished out.
