BB460
Self-Adhesive Butyl Damping Sheet
Self-adhesive damping sheet that stops metal panels ringing. Peel, press, done: 2 mm butyl with an aluminium face, 3.86 kg/m², for ducts, hoppers, machine guards and vehicle panels. BB460 BlastVib is a black butyl rubber constrained-layer damping sheet with an aluminium foil face and a self-adhesive back. It damps the structure-borne vibration of the panel it is stuck to, so sheet metal, ducts, hoppers, machine housings and guards, enclosure panels and vehicle door skins and floor pans stop resonating. It is not a mass loaded vinyl barrier and does not replace MLV for blocking airborne sound through a wall: use BB460 on the ringing panel, plus BB830 or BB830LF where airborne sound must be blocked.

About BB460: Engineered for Acoustic Excellence
BlastBlock BB460 BlastVib is a self-adhesive vibration damping sheet: 2 mm of black butyl rubber with an aluminium foil face, weighing about 3.86 kg/m² and supplied in 500 × 10,000 mm rolls of 5 m².
Its job is to stop thin panels ringing. Sheet metal, ducts, hoppers, machine housings and guards, enclosure panels and vehicle body panels resonate when machinery, airflow, impacts or the road excite them, and a resonating panel radiates noise from its whole surface. BB460 works as a constrained-layer damper: when the panel flexes, the butyl is sheared between the panel and the aluminium face, so the vibration energy is dissipated in the butyl instead of being radiated as sound. The panel stops drumming, booming and rattling.
BB460 damps the structure-borne vibration of the panel it is stuck to. It is not a mass loaded vinyl barrier, and it does not replace MLV where airborne sound has to be blocked through a wall, floor or enclosure. The usual approach uses both: BB460 on the panel that rings, and BB830 or BB830LF where airborne sound must be blocked.
Installation is peel, press, done. Clean and degrease the panel, cut the sheet to size, remove the release liner and press it down firmly, rolling it so the butyl is in full contact with the metal. At 2 mm it conforms to curved and ribbed panels and adds very little build-up inside door cavities, under carpet or on machine guards.
The weight is easy to plan for: about 3.86 kg for every square metre treated. Put BB460 on the panels that actually ring, such as duct walls, hopper sides, guard panels, door skins and floor pans, and the added weight stays in proportion to the problem.
BB460 Panel Damping Installation
- 1Identify the panels that ring: tap them and listen for drumming. Typical targets are duct walls, hoppers, machine guards, enclosure panels, door skins and floor pans.
- 2Clean surfaces thoroughly - the self-adhesive back needs a clean, dry, oil-free surface.
- 3Measure and cut the sheet using a utility knife or heavy scissors.
- 4For curved surfaces, use heat gun to increase flexibility during application.
- 5Peel backing and apply firmly, rolling with J-roller to ensure complete contact.
- 6Butt adjoining pieces neatly; BB460 works by bonding to the panel, so full contact matters more than seams.
- 7Keep drain holes, fixings and access points clear.
- 8For marine applications, seal edges with BA890 for moisture protection.
- 9Where airborne sound must also be blocked, add BB830 or BB830LF as the barrier layer.
Technical Advantages
- Constrained-layer damping: butyl rubber sheared under an aluminium foil face
- Stops thin metal panels ringing, drumming and rattling
- Self-adhesive back: peel, press, done
- 2 mm thick, so it fits inside door cavities, under carpet and behind trim
- About 3.86 kg/m², so the added weight is easy to calculate
- Conforms to curved and ribbed panels
- Works alongside BB830 and BB830LF, which block airborne sound
- Supplied in 500 × 10,000 mm rolls (5 m²)

Read the full methodCommon Use Cases for BB460
BB460 on door skins, the floor pan and the trunk floor stops those panels resonating, which takes the drumming and rattle out of road and engine noise. Add BB830 where airborne noise must be blocked as well.
Metal casings, panels and hatches around engines and generators ring when the machinery runs. BB460 damps those panels; BB830LF blocks the airborne engine noise.
Sheet-metal ducts, plenums and air handler casings drum and radiate noise. BB460 on the casing damps the panel resonance; add BB830 where airborne break-out must be blocked.
Thin panels in vans, show cars and custom builds ring with road input and audio. At 2 mm, BB460 damps door skins, floor pans and roof panels and still fits behind the trim.
Enclosure panels, machine guards and hoppers can resonate and become noise sources themselves. BB460 damps the panel; BB830LF provides the airborne barrier.
