ACOUSTIC CURTAIN 4B<\/strong><\/p>\n

Acoustic Curtain 4B for sound absorption, highly durable, protects against light, sound, temperature and fire.<\/p>\n

LIGHT \u2013 OPACITY:<\/strong> The light-blocking properties of the Acoustic Curtain 4B are based on the nature of the materials in its sheets, particularly their density and thickness.<\/p>\n

SOUND \u2013 ACOUSTIC ABSORPTION:<\/strong> The sound absorption and attenuation properties of the Acoustic Curtain 4B are based on the nature of the materials in its sheets, particularly their density, flexibility and porosity. Tested to UNE-EN ISO 354:2004, it absorbs over 90% of sound and insulates 8 dB. <\/p>\n

TEMPERATURE \u2013 THERMAL INSULATION:<\/strong> The Acoustic Curtain 4B offers thermal insulation properties thanks to the low thermal conductivity and resistance to airflow of the materials in its sheets.<\/p>\n

FIRE \u2013 REACTION TO FIRE:<\/strong> The Acoustic Curtain 4B is classified as Class 1 according to UNE EN 13773:2003.<\/p>\n
