Glass wool is a type of insulating material that is made from glass fibres that have been bound together with a binder to give them a texture similar to wool. This lightweight partition wall, stairwells, elevator shafts, neighbouring walls, and interior surfaces of outer walls may all be thermally and acoustically isolated with this glass wool inner partition board. It is inserted into the building as a Glass Wool Inner Partition Board. The side of the board facing the inside or both sides, depending on the application space, are affixed.
