Construction

Built to Withstand, Designed to Perform

Every Sonic Access Acoustic Door is designed for durability and consistent use in industrial settings. Each Sonic Access acoustic door includes:

  • 80mm thick door leaf with high-density core (91.9 kg/m²)
  • Double-runner perimeter seals for maximum sound isolation
  • Reinforced steel frame and welded ball-bearing hinges
  • Factory-applied powder coat finish
  • Weatherproof, dustproof and vermin-resistant construction
  • Supplied as a complete unit with our SonicFix ready-to-install system

Need a Fire-Rated Option?

If your project requires fire compliance as well as noise control, we’ve got you covered. Our SonicGuard acoustic fire door provides a certified fire rating with reliable acoustic performance.

While the acoustic rating is reduced compared to Sonic Access, SonicGuard is engineered for applications where both fire safety and noise reduction are essential.

Ask our team about how SonicGuard can fit into your acoustic design.

Why Acoustic Doors Matter

Noise rarely stays in one place. But your operations often need it to. Sonic Access doors provide a practical way to contain unwanted sound while maintaining access and security.

  • Maintain compliance with workplace noise standards
  • Prevent sound leakage into surrounding areas
  • Improve comfort and communication in adjacent spaces
  • Avoid unnecessary downtime with doors ready for immediate use after install

Frequently Asked Questions

  • Industrial acoustic doors are specialised doors designed to minimise the transmission of noise in industrial settings. They typically feature heavy-duty construction and specialised soundproofing materials to achieve this goal, distinguishing them from regular doors.

     

  • Industrial acoustic doors employ various soundproofing techniques, such as multiple layers of dense materials, acoustic seals, and specialised construction methods to reduce noise transmission. These features help create a barrier preventing noise from passing through the door effectively.

     

  • Factors such as the level of noise reduction required, the size and dimensions of the doorway, environmental conditions, and any specific regulatory requirements must be taken into account. Additionally, considerations such as durability, maintenance requirements, and compatibility with existing infrastructure should also be considered.

     

  • Yes, industrial acoustic doors can often be customised to fit specific industrial environments. This customisation may include adjustments to size, materials, finishes, and additional features to meet the unique needs of the application.

     

  • The noise reduction ratings of industrial acoustic doors can vary depending on construction materials, thickness and design. However, they typically have high Sound Transmission Class (STC) ratings ranging from 40 to 60 or higher, indicating their effectiveness in reducing noise transmission.
