What is Fellert?

Fellert is a hand-crafted seamless sound absorption
system. The Fellert system originated in Sweden
and consists primarily of fiberglass boards and
acoustical plaster.

The fiberglass board is typically attached to gypsum
wall board with a cementitous adhesive; the
acoustical plaster is mixed with water and applied
with a spray machine and troweled to an
approximate thickness of 1⁄8".
