BlastBlock vs Tecsound — Acoustic MLV Comparison
Tecsound is a high-density viscoelastic acoustic membrane manufactured by Soprema, a major French construction materials company. Tecsound is widely distributed in Europe and is commonly specified for soundproofing walls, floors, and ceilings in commercial and residential construction. It is available in several weight variants and is known for its consistent quality within the European market.
Summary
Both Tecsound and BlastBlock are quality acoustic membrane products used in professional soundproofing applications. BlastBlock differentiates through its ASTM E90 independent acoustic testing documentation, a dedicated fire-rated product line (BB830FR, tested to AS/NZS 1530.3 without brominated flame retardants), and a specialized heavy-duty low-frequency variant (BB830LF, 10 kg/m², 5mm) for demanding bass-blocking applications. BlastBlock also distributes from Rotterdam, Netherlands with Asia-Pacific stock in Bangkok, Thailand.
Tecsound's primary strength is its establishment in the European market and Soprema's extensive distribution network. The product performs consistently in standard construction applications. BlastBlock's acoustic optimization approach — engineering the compound specifically for acoustic performance rather than using a generic dense polymer — delivers verified STC 32 dB performance from BB830 and targets the specific frequency ranges where residential and commercial noise is most problematic. For project teams requiring fire-rated documentation, BB830FR offers a specification-ready fire-rated MLV with available ASTM test reports. For projects requiring low-frequency heavy-duty isolation (home theaters, studios, industrial machinery), BB830LF provides a purpose-built solution that Tecsound's standard lineup does not specifically address.

Frequently Asked Questions
How does BlastBlock compare to Tecsound in acoustic performance?
BlastBlock BB830 achieves STC 32 dB in ASTM E90 testing. Tecsound products achieve comparable performance in their respective weight categories. The key difference is BlastBlock's acoustic optimization formulation, which is specifically engineered for sound blocking rather than being a general-purpose dense polymer membrane. BlastBlock ASTM test reports are available on request for project specification.
Is BlastBlock or Tecsound better for fire-rated construction?
BlastBlock BB830FR is specifically tested and certified to AS/NZS 1530.3 fire safety standards with available ASTM fire documentation. For projects requiring a fire-rated acoustic membrane with documented certification, BB830FR provides a specification-ready solution with eco-friendly fire-retardant chemistry that avoids brominated flame retardants.
Where can I buy BlastBlock as a Tecsound alternative?
BlastBlock is distributed from Rotterdam, Netherlands for European buyers and Bangkok, Thailand for Asia-Pacific buyers. Contact info@blast-block.com for distributor information, pricing, and sample requests in your region.
Can BlastBlock be installed the same way as Tecsound?
Yes. BlastBlock MLV installs using the same methods as other acoustic membrane products — applied with BA990 adhesive, overlapped at seams, and sealed with BA890 acoustic sealant at all perimeters and penetrations. The material cuts easily with a standard utility knife. Installation guidance and technical datasheets are available from BlastBlock.
