Acoustic Batts

Inno-Therm®/Metisse® meets or exceeds quality and performance standards of conventional insulation products. Composition 85% recycled cotton. The acoustic eko batts are 45 mm x 600 mm wide x 1.2 m long. The thermal conductivity is 0.044 W/(mK). The  product has a high coefficient of sound absorption (= 0,95) and acoustic fading is 42 dB with a density of 45 kg/m3(+/-10%).

The insulation allows, besides its hydrothermal performance, to provide acoustic comfort and that even with a little thickness. There is also a thermal/acoustic product with a thickness of m+ 50 mm – density of 25 kg/m3 – (0.039 W/(mK) and it achieves a weighted sound absorption coefficient αW = 0.85 and acoustic fading is 42 dB

The results are derived from acoustic measurements in accordance with ISO 11 654 standard made by the ICAM linked to the UTC the 10/05/2008.

Inno-Therm® can supply acoustic rolls of 20 mm thickness x 1.2 m width with a density of 45 kg/m3 with a high coefficient of sound absorption (0.95) and acoustic fading is 20 dB.
