A low cost, high-performance, and easy to fit solution to providing acoustic performance for ceiling and walls.

The Isosonic Acoustic Ceiling Brackets - 125mm Arm are a versatile and cost-effective solution for enhancing acoustic insulation in both ceilings and walls. Designed to reduce sound transmission and vibration between structural elements, these brackets deliver excellent noise reduction, achieving up to an 18dB improvement in sound attenuation. Whether for residential, commercial, or refurbishment projects, the Isosonic brackets provide superior performance with easy installation, making them a go-to choice for professional and DIY soundproofing applications.

What is an Acoustic Ceiling Bracket?

An acoustic ceiling bracket is a decoupling mechanism used in soundproofing systems to isolate ceilings or walls from the structural framework, reducing noise transfer. The Isosonic Ceiling Brackets feature a 125mm arm that accommodates 50x50mm battens or 50mm wide ceiling channels. These brackets work by decoupling the ceiling or wall from the structural floor or joists, effectively reducing vibration and sound transmission.

Key Features:

  • Designed for use with timber joists or concrete floors.
  • Suitable for both new builds and refurbishment projects.
  • Provides a ceiling drop of 50mm to 135mm.
  • Compatible with both timber battens and metal framing systems.

The Key features of Isosonic brackets:

How Does the Isosonic Acoustic Ceiling Bracket Work?

The Isosonic Acoustic Ceiling Bracket functions as a decoupling mechanism that isolates the ceiling or wall from the main structure. This isolation prevents sound vibrations from transferring directly between surfaces, reducing both airborne and impact noise.

  1. Decoupling Action:
    The bracket separates the structural floor or joists from the ceiling or wall, interrupting the sound path.
  2. Vibration Dampening:
    An integrated acoustic pad within the bracket absorbs vibrations, further enhancing its soundproofing performance.
  3. Flexibility:
    The bracket can hold timber or metal channels, allowing flexibility in installation and compatibility with various construction methods.

By minimising direct contact between structural components, these brackets significantly reduce flanking noise and improve overall acoustic performance.

How Effective Are the Isosonic Acoustic Ceiling Brackets at Stopping Nuisance Noise?

Do Isosonic Acoustic Ceiling Brackets Work? Absolutely. With an 18dB reduction in noise transmission, these brackets outperform traditional resilient bars and other decoupling systems, offering a superior soundproofing solution.

  • Impact Noise Reduction: Excellent at minimising vibrations from footsteps and other impacts.
  • Airborne Noise Reduction: Effectively isolates voices, music, and other airborne sounds.
  • Improved Acoustic Integrity: Adding mineral wool to the ceiling or wall void can enhance performance by an additional 1-2dB.

This makes the Isosonic brackets an ideal choice for applications where effective noise control is essential.

Where Can the Isosonic Acoustic Ceiling Brackets Be Used?

The Isosonic Acoustic Ceiling Brackets are versatile and suitable for a wide range of environments, including:

  • Residential Projects: Ideal for soundproofing between floors or walls in homes.
  • Commercial Spaces: Reduces noise transfer in offices, retail spaces, and meeting rooms.
  • Educational Institutions: Enhances acoustic privacy in classrooms and study areas.
  • Refurbishments: Upgrades existing ceilings and walls without extensive structural changes.
  • Stud or Brick Walls: Works effectively with various wall types, including stud and brick constructions.

How to Install the Isosonic Acoustic Ceiling Brackets

Installation is straightforward, making the brackets suitable for professionals and DIY enthusiasts:

  1. Preparation:
    • Measure the room and calculate the number of brackets needed (approximately 2.5 brackets per m²).
  2. Fixing the Brackets:
    • Attach the brackets to the underside of the structural floor or the side of joists, ensuring a consistent spacing of no more than 800mm.
  3. Installing Battens or Channels:
    • Fit 50x50mm timber battens or 50mm wide ceiling channels into the brackets.
  4. Adding Acoustic Materials:
    • For enhanced performance, insert mineral wool into the ceiling or wall void.
  5. Securing Plasterboard:
    • Attach acoustic-grade plasterboard to the battens or channels, ensuring all joints are sealed with acoustic sealant.

By following these steps, you’ll achieve a high-performing soundproofed ceiling or wall with minimal effort.
