Insulation Materials

Materials which have substantially greater ability to absorb sound than other conventionally used materials (wood, glass, concrete) are called acoustic materials.

Types of Sound Proofing materials

Acoustic materials can be classified into three main groups

ACOUSTIC TILES:

A majority of tiles used for acoustic purposes are made from wood, cane fibers matted and bonded into sheets of various thickness ranging from (3/16) in to (5/4)in. The sheets are cut into tiles of different sizes.

ASSEMBLED UNITS:

Assembled units consist of some types of sound absorbing materials such as rock-wool or fiber-glass blankets fastened to an acoustically transparent facing. This facing is generally some kind of rigid board, such as hard board or a metal sheet.
