Fire Performance

Euroclass B, s2, d0 in accordance with UNE-EN 13823:2002 and UNE-EN-ISO 11925-2:2002. (considered superior to the old BS Class 0 non-flammable rating)
• B – Likelihood of combustion very limited.  The test showed that fire does not go beyond the limited area in which a flame has been applied.
• S2 – Average emission and speed of smoke production.
• D0 – No flammable dripping produced.

The above classification makes Tecsound the superior alternative to most other sound proofing mats in terms of non-flammability.  It is the first soundproofing membrane available to receive Euroclass Certification – Euroclass.

Standards above B (A1 and A2) are given to completely non-flammable products.  Materials between Euroclass A and B are the safest in a fire situation.

Fire testing was conducted with the product hung as a curtain and with no other mechanical support or backing giving an accurate assessment of its fire resistance.
