Woolfelt improves acoustic conditions in spaces which makes it suitable to use on floors, walls and ceilings. Woolfelt can be glued directly onto walls. First the glue is applied on the walls, then the Woolfelt is pressed into the glue. 

 

The natural properties of Woolfelt (non-flammable, insulating, dirt- and water repellent) make it suitable to use in public buildings such as hospitals, theatres, restaurants and museums, even without additional treatments.
