BlastBlock vs Green Glue
Green Glue is a viscoelastic soundproofing compound used between layers of drywall to convert sound energy into heat. Unlike MLV (mass loaded vinyl), Green Glue is a layer-applied compound — not a standalone barrier. Many soundproofing projects use both MLV barriers AND Green Glue for maximum noise reduction. BlastBlock MLV can be used alongside or as an alternative to Green Glue depending on your application.
| Feature | BlastBlock | Green Glue |
|---|---|---|
STC Rating | BB830: STC 32 | BB830FR: STC 28 | BB830LF: STC 32+ | Works additively in drywall assemblies |
Thickness Options | 3mm (BB830/FR) | 5mm (BB830LF) | Applied as thin compound layer |
Surface Weight | BB830: 5 kg/m² | BB830LF: 10 kg/m² | Negligible — compound application |
Fire Rating | BB830FR: Fire tested to AS/NZS 1530.3 | Non-rated — check building codes |
Eco-Friendly | BB830FR formulated without brominated flame retardants | Water-based formulation |
ASTM Testing | ASTM E90 test reports available on request | ASTM E90 tested in drywall assemblies |
Acoustic Optimization | Formulated for frequency response optimization | Damping compound — reduces resonance |
- ASTM E90 laboratory tested - test reports available on request
- Fire-rated option available (BB830FR)
- BB830FR formulated without brominated flame retardants
- Multiple thickness options: 3mm and 5mm
- Low-frequency variant (BB830LF) for bass and machinery noise
- European headquarters (Netherlands) with Asia-Pacific distribution
- Technical support and datasheets available
Strengths
- Effective at reducing mid to high frequency resonance
- Easy to apply between drywall layers
- Good test data in drywall sandwich assemblies
- Low profile — no added thickness beyond drywall
Considerations
- Works only in drywall-to-drywall assemblies
- Cannot be used as standalone barrier
- No benefit for structure-borne or low-frequency noise alone
- Must be combined with MLV for best results
- Requires complete wall rebuild to apply properly
Green Glue and BlastBlock serve different but complementary roles. Green Glue is a damping compound applied between drywall layers to reduce resonance — it requires structural installation. BlastBlock MLV is a standalone acoustic barrier that can be added to existing walls, ceilings, floors, HVAC ducts, automotive panels, and marine applications without rebuilding. For maximum soundproofing, many professionals use MLV barriers together with Green Glue for a complete system.
