High-Density Rubber Soundproofing Panel for Partition Walls
MGEL is a high-density (700 kg/m³) recycled rubber soundproofing panel engineered to increase the surface mass of partition walls and reduce airborne noise transmission between rooms. Available in two formats, 1.00 × 1.20 m for direct manual installation and 1.20 × 2.00 m for stud-framed double-wall systems, in 15 and 20 mm thicknesses. Made from recycled vulcanized rubber, MGEL is built for distributors and manufacturers of acoustic drywall panels who need a dependable component available in bulk volumes and easy to integrate into their own wall systems.
What is MGEL: the recycled rubber panel for partition wall soundproofing
MGEL is a high-mass, recycled vulcanized rubber panel designed specifically to reduce the airborne noise that passes through partition walls. Unlike sound-absorbing materials (which manage reverberation inside a room), MGEL works as a soundproofing barrier: its high density in a compact thickness increases sound insulation performance without requiring excessive wall thickness — a decisive advantage in retrofit projects where available space is limited.
The panel is designed to be integrated into dry-wall systems (drywall, stud-framed double walls) or applied directly to existing masonry, making it a versatile solution both for renovation of apartments and offices and for industrial production of prefabricated acoustic panels.

- Made from recycled rubber, aligned with circular-economy criteria increasingly required in public procurement specifications
Installation guide: how to install MGEL panels
Direct installation on an existing wall (MGEL 100×120)
1. Preparation
2. Bonding
3. Sealing
4. Covering
5. Details
Remove any loose or flaking plaster, sand away dust, and check for residual moisture on the wall surface; repair cracks and irregularities beforehand, since an uneven substrate weakens adhesion and can create acoustic bridges once the wall is closed up.
Apply polyurethane foam or a specific high-hold adhesive in spots or continuous beads across the back of the panel, then position it against the wall and press firmly along the whole surface to ensure uniform, air-tight contact with no gaps.
Seal every joint between adjacent panels and the full perimeter against floor, ceiling and adjoining walls with acoustic mastic, since even a small unsealed gap can significantly reduce the overall airborne sound insulation of the finished wall.
Apply two staggered layers of drywall over the MGEL panel, offsetting the joints between the two layers and carefully filling and sealing every seam, in order to maximize the overall mass and continuity of the finished partition wall.
Seal electrical outlets and switch boxes with acoustic putty pads, and check for flanking noise paths such as skirting boards, adjoining stud walls and service penetrations, since these are common weak points that let airborne noise bypass the panel.
Stud-framed double-wall system (MGEL 120×200)
1. Frame
2. Placement
3. Fixing and sealing
4. Finishing
Set up a metal or wood stud frame with adequate spacing between uprights, sized according to the wall height and the loads it will support, making sure the structure is plumb and securely anchored before any panel is fitted to it.
Fix the first drywall board to one side of the frame, bond the MGEL panel directly onto it or onto the studs, then complete the assembly with a second drywall board on the same side, staggering its joints against the first layer.
Fix all boards with screws that comply with the frame type and board thickness, then seal the full perimeter and every joint between panels with acoustic mastic, since unsealed edges create direct paths for airborne noise to pass through.
Apply the chosen surface finish once the boards are fixed, and carefully check that the acoustic sealing is continuous along the entire perimeter of the wall, with no gaps left at corners, floor, ceiling or adjoining structures.
Laboratory testing and Rw certification
The double-wall system with an interposed MGEL 20 panel has been tested at an accredited laboratory according to UNI EN ISO 10140-2:2021, achieving a weighted sound reduction index of Rw(C) = 54 (-1) dB, with Rw = 54.2 dB (±0.6 dB measurement uncertainty).
The test was carried out on a complete double clay-brick wall system with MGEL 20 interposed in a 30 mm air gap, for an overall mass per unit area of 157 kg/m² over an effective acoustic surface of 10.8 m².
Why Rw certification matters
- Rw is the reference index for airborne sound insulation and quantifies noise reduction between spaces.
- An accredited laboratory test guarantees repeatable results, recognized nationally and across Europe.
- The value achieved (Rw = 54.2 dB) allows designers and contractors to size interventions and declare performance in technical specifications with verifiable data.
- The laboratory test has now been completed: discover the detailed results, the tested system’s composition, and the Rw value achieved in our dedicated technical article.

Frequently asked questions about MGEL rubber panel
How do you soundproof a room?
Soundproofing a room requires increasing wall mass, sealing every gap, and reducing flanking noise paths. Effective solutions include applying high-density panels like MGEL combined with two staggered layers of drywall and proper sealing of joints and outlets.
Is rubber a suitable acoustic insulator for partition walls?
Yes. High-density rubber materials provide mass and damping that reduce airborne noise transmission. Performance depends on density, thickness, and how the panel is integrated into the overall wall system.
How much does a rubber panel like MGEL reduce airborne noise?
Reduction depends on the overall system the panel is integrated into. Combined with double drywall and proper sealing, high-mass panels can contribute to a significant insulation improvement. Official Rw/STC figures come from accredited laboratory tests, currently underway for the MGEL system.
Is MGEL suitable for panel manufacturers ordering bulk volumes?
Yes. MGEL is available for B2B bulk supply, including private label, for distributors and manufacturers of acoustic drywall panels who need a recycled rubber component with consistent specifications batch to batch.
What adhesives and finishing materials should be used with MGEL?
Use polyurethane foams or specific adhesives designed for high-mass panels, and acoustic mastic to seal joints and perimeters. Use acoustic putty for electrical outlets. Follow adhesive technical data sheets for compatibility and set times.
