Acoustical panel

An acoustic building panel having a first major surface opposite a second major surface and a third major side surface extending there-between, the acoustic building panel comprising:

• a body having an upper surface opposite a lower surface and side surfaces extending there-between;
• a fiberglass fleece having a first side opposite a second side and a basis weight ranging from about 40 g/m2 to about 100 g/m2;
• wherein the first side of the fleece is in contact with the upper surface of the body and at least a portion of the side surfaces of the body;
• wherein the body and fleece are laminated;
• and
• wherein the fleece has a flow resistivity of about 826,100 to about 1,090,900 Pa*s/m2.

A surface covering system comprising:

• a plurality of acoustic building panels, each of the panels comprising a first major surface opposite a second major surface and a third major side surface extending there-between, the acoustic building panel further comprising:
• a body having an upper surface opposite a lower surface and side surfaces extending there-between;
• a fleece having a first side opposite a second side and a basis weight ranging from about 40 g/m2 to about 100 g/m2;
• wherein the first side of the fleece is in contact with the upper surface of the body;
• wherein the body and fleece are laminated;
• and
• wherein the fleece has a flow resistivity of about 826,100 to about 1,090,900Pa*s/m2;
• and
• an adhesive tape configured to detachably couple the panels to a substrate, the adhesive tape comprising:
• a substrate-side adhesive component comprising at least one adhesive layer;
• a panel-side adhesive component comprising at least one adhesive layer;
• and a release component;
• wherein the panels are detachably coupled to the substrate by the adhesive tape in a side-by-side arrangement to cover the substrate, the at least one adhesive layer of the substrate-side adhesive component being adhered to the substrate, the at least one adhesive layer of the panel-side adhesive component being adhered to the rear surfaces of the panels, and the release component being positioned between the substrate-side adhesive component and the panel-side adhesive component.
