CD Reef V4 CSTB 2021: A Comprehensive Technical Deep Dive into the Acoustic Underlayment Standard

Accessories & mounting

• Included: wrist strap, mount, USB cable, manual, neoprene cover
• Optional: chest strap, transmitter for tank pressure, scooter mount, docking cradle

Step 4: Screed Application

• Minimum screed thickness: 50mm (cementitious) or 55mm (anhydrite).
• Maximum screed thickness: 100mm (beyond this, dynamic stiffness benefits diminish).
• Apply a separation film (200-micron PE) over the Reef if using fluid anhydrite to prevent binder migration into the elastomer matrix.

CD Reef V4 vs. Traditional Alternatives

To appreciate the value of the CSTB 2021 certification, compare the CD Reef V4 to other 2021-era solutions:

If you are specifying acoustic insulation for a new build or renovation, understanding the nuances of the CD Reef V4 CSTB 2021 technical dossier is non-negotiable for code compliance and occupant comfort. Included: wrist strap, mount, USB cable, manual, neoprene

Environmental & compliance

• Operating temperature: (e.g., -10°C to 40°C)
• Storage temperature: (e.g., -20°C to 60°C)
• Certifications: CE, RoHS, FCC, and any diving-specific approvals (e.g., EN250 for breathing devices)
• Pressure test / hydrostatic test ratings (if applicable)
