Acoustic insulation works by absorbing sound and vibrational energy. The principle is to convert sound energy into kinetic energy.
Glasswool is a good sound insulator because the flexing action of the fibers absorbs the sound and dissipates it in a form of heat energy if
such low density as to be virtually undetectable. Glasswool has excellent sound absorption characteristics and with complementary building
materials. It enhances the performance of a structure by minimizing the passage of sound. Acoustic irritation is reduced and hearing
protected. So glasswool-made products are widely used in large buildings, exhibition halls, hospitals, etc., where special needs for sound
proofing, noises control or acoustic insulation are desired.
