Our acoustic panel has a weighted absorption coefficient (αw) of 0.25 (class E EN ISO 11654), but its efficiency is much more pronounced against the real danger – the high-pitched noises – where the absorption coefficient (αs) reaches 0.95! Whilst most other desk top screens behave the opposite (absorbance is high for low-pitched noises but low for high-pitched ones).
These acoustic panels are fire-resistant, certified to BS EN 13501 Class B (D0 S1) standards. What is Class B fire rating? In simple terms it means the material has very limited contribution to fire. “d0 s1” are the best performance scores in Class B rating, “D0” means none “flaming Droplets and particles” and “S1” means no or very little “Smoke propagation”. Other performances scores in Class B fire ratings are: D1 = some; D2 = quite a lot; and S2 = quite a lot of smoke; S3 = substantial smoke
