Overview
The BXI Double Noise Blocker uses a dual-layer construction for sound absorption and vibration dampening. Also, it combines multi-layer space cotton with a dense rubber soundproofing layer.
The material is designed to target airborne sound and vibrational energy in enclosed spaces. It supports noise control around HVAC ducts, machines, pipes, conduits, windows, and interior walls. In addition, its flexible structure supports placement on curved, uneven, or irregular surfaces.
The construction lists an average transmission loss of 24dB and an NRC rating of 0.75. These figures relate to its stated sound transmission and absorption characteristics. The material also supports supplementary acoustic treatment alongside mass loaded vinyl or drywall.
Key takeaways
- The dual-layer sound absorption material combines space cotton with dense rubber.
- The foam layer faces the noise source, while the rubber layer supports vibration dissipation.
- The construction lists a 24dB average transmission loss and an NRC rating of 0.75.
- Pre-applied 3M double-sided adhesive strips and five zip ties support installation.
- The flexible composite supports pipes, conduits, HVAC ducts, machines, walls, and vehicle areas.
- The closed-cell material features moisture resistance, heat resistance, and tear resistance.
What the product is designed to do
The material supports sound absorption and vibration dampening through two different layers. Also, the multi-layer space cotton forms the absorption layer. The dense rubber forms the soundproofing and vibration-dissipation layer.
This construction targets airborne sound and vibrational energy within enclosed spaces. For example, it supports noise control for HVAC ducts, compressor enclosures, pipes, machines, and engine compartments.
The panel also supports echo reduction within small rooms or studios. In addition, it can serve as supplementary acoustic treatment beside mass loaded vinyl or drywall.
Its application range covers windows, interior walls, trunk spaces, and wheel wells. The flexible structure also supports targeted noise control around cylindrical or irregular surfaces.
Materials, dimensions, and technical details
| Feature | Technical detail |
|---|---|
| Construction | Dual-layer foam-and-rubber composite |
| Absorption layer | Multi-layer space cotton |
| Soundproofing layer | Dense rubber |
| Transmission loss | 24dB average |
| NRC rating | 0.75 |
| Material structure | Closed-cell, flexible, pliable, and compressible |
| Fastening components | Pre-applied 3M double-sided adhesive strips and five zip ties |
| Material characteristics | Moisture-resistant, heat-resistant, tear-resistant, and non-toxic |
The foam-and-rubber composite supports trimming with standard cutting tools. Also, its flexible and conformable structure supports fitting around curved, uneven, or irregular surfaces.
The closed-cell construction supports acoustic insulation in residential, studio, automotive, and mechanical settings. In addition, the material supports thermal resistance around temperature-sensitive components.
Installation and placement notes
The foam side is intended to face the noise source. Also, the rubber layer faces outward to support vibration dissipation.
For pipe or conduit applications, the material can wrap around the cylindrical surface. The included zip ties support fastening around piping or tubular elements.
Pre-applied 3M double-sided adhesive strips support mechanical bonding on suitable surfaces. In addition, the pliable and compressible structure supports fitting into irregular cavities.
The material can be trimmed with standard cutting tools before placement. Next, the cut section can conform around HVAC tubing, machinery, walls, windows, or vehicle areas.
Placement depends on the intended noise source and surface shape. The flexible sound deadening material supports both flat areas and curved components.
Performance characteristics described
The construction lists an average transmission loss of 24dB. Also, it lists an NRC rating of 0.75.
Transmission loss relates to the stated reduction of sound passing through the material. NRC relates to the stated absorption of sound energy.
The dual-layer structure targets two acoustic functions. The space cotton supports absorption, while the dense rubber supports soundproofing and vibration dissipation.
This combination supports dampening of airborne sound and vibrational energy. For example, it suits targeted treatment around HVAC ducts, compressors, pipes, engines, trunk spaces, and wheel wells.
The material also supports echo reduction in small rooms or studios. However, the supplied wording places it within supplementary acoustic treatment alongside barriers such as mass loaded vinyl or drywall.
Its closed-cell structure adds moisture resistance, heat resistance, and tear resistance. The foam and rubber soundproofing layer also supports thermal resistance around equipment and piping.
