Bondex Foam – High-Density Rebonded Foam

Bondex Rebonded Foam

Bondex foam (rebonded polyurethane foam) is a high-density, composite acoustic material engineered for heavy-duty sound insulation, noise isolation, and vibration dampening. Manufactured by recycling and compressing polyurethane foam particles under extreme pressure, Bondex provides significantly higher density and mass than conventional foam panels, making it an exceptional barrier against airborne noise transmission and unwanted sound leakage.

Designed for residential developments, recording studios, industrial plant rooms, and commercial facilities, Bondex foam effectively cuts high-decibel background noise, controls interior acoustic reflections, and eliminates noise pollution between adjacent spaces. Its compact cell matrix also provides auxiliary thermal barrier performance, optimizing heating and cooling efficiency within building envelopes. Durable, rot-resistant, and chemically stable, Bondex delivers a high-performance acoustic lifecycle with virtually zero maintenance.

Where and How Is Bondex Foam Applied?

Thanks to its balanced density and high sound transmission loss, Bondex foam serves as both an exposed acoustic treatment and a concealed core layer:

  • Recording Studios & Production Suites: Applied on perimeter boundaries and control room walls to trap low-frequency energy and prevent bleed into adjacent rooms.

  • Commercial Offices & Workspaces: Integrated into partition walls to prevent speech crossover and keep acoustic privacy intact.

  • Cinemas, Auditoriums & Home Theaters: Blocks external environmental rumble while controlling mid-to-low frequency resonance inside the viewing hall.

  • Classrooms & Educational Facilities: Applied on shared classroom walls and ceilings to control noise transfer and sharpen speech intelligibility.

  • Hospitality & Dining (Cafes & Restaurants): Dampens ambient crowd reverberation across busy open floor plans.

  • Industrial & Plant Equipment Rooms: Used as acoustic lining inside generator canopies, compressor enclosures, and mechanical pump rooms.

Installation Process

  • Acoustic Profiling: Identify targeted decibel drop goals (dB) and determine whether the application requires wall, ceiling, or under-screed floor placement.

  • Substrate Preparation: Ensure base surfaces (brick, concrete block, dry construction frames) are dry, smooth, and free of oil or contaminants.

  • Panel Mounting: Affix panels using specialized high-tack acoustic contact adhesive or water-based polyurethane adhesives. Mechanical anchors may be used for heavy-duty ceiling runs.

  • Surface Finishing: Bondex can remain exposed, covered with acoustic fabric finishes, or fully concealed behind double layers of gypsum boards for drywall soundproofing assemblies.

  • Precision Trimming: Panels cleanly slice and cut on-site using standard utility cutters or foam saws to accommodate electrical runs and wall corners.

Technical Highlights

  • Eco-Conscious Production: Formulated from recycled open-cell polyurethane chips, promoting sustainable circular manufacturing.

  • Flame Retardancy: Treated to comply with rigorous international flammability requirements.

  • Exceptional Sound Transmission Loss: High volumetric mass provides a strong acoustic barrier against both airborne and impact sound.

  • Substrate & Facing Compatibility: Bonds readily with gypsum board, heavy acoustic vinyl barriers (EPDM/Mass Loaded Vinyl), and decorative textiles.

  • Flexible On-Site Shaping: Easy to size, slice, and contour around architectural irregularities without structural crumbling.

Key Features & Benefits of Bondex Foam

  • High-Mass Sound Absorption & Blocking: The compressed cellular structure dampens deep acoustic frequencies and prevents sound breakthrough between rooms.

  • Extensive Thickness & Profile Options: Supplied in various thicknesses and custom-cut slab dimensions to fulfill precise acoustic engineering plans.

  • High Structural Integrity & Longevity: Retains mechanical bounce and acoustic performance over decades without sagging, rotting, or flaking under ambient humidity shifts.

  • Straightforward Installation: Modular slabs mount quickly using contact bonding methods, reducing labor time across broad wall and ceiling surfaces.

  • Safe & Non-Toxic Profile: Free from volatile organic binders, heavy toxins, or airborne fibers, ensuring a healthy indoor environment for installers and occupants alike.

  • Thermal Insulation Value: The dense polyurethane composition doubles as a thermal buffer, stabilizing indoor temperatures and cutting HVAC energy consumption.
