Acoustic structural building panels

An acoustic structural panel having a first exposed major surface opposite a second exposed major surface and side surfaces extending between the first and second exposed major surfaces, the acoustic structural panel comprising:

• a first protective layer comprising at least a portion of the first exposed major surface;
• a second protective layer comprising at least a portion of the second exposed surface;
• a core structure located between the first and second protective layers,
• wherein the first major exposed surface of the acoustic structural panel comprises a plurality of apertures exposing the fibrous body, wherein the side surfaces comprise a first side surface opposite a second side surface, the first side surface comprises a first interlocking profile and the second side surface comprises a second interlocking profile, the first interlocking profile being complimentary to the second interlocking profile.

An acoustic structural panel having a first exposed major surface opposite a second exposed major surface and side surfaces extending between the first and second exposed major surfaces, the acoustic structural panel comprising:

• a first protective layer comprising at least a portion of the first exposed major surface;
• a second protective layer comprising at least a portion of the second exposed surface;
• a core structure located between the first and second protective layers, the core structure comprising
• a first body having a first major surface opposite a second major surface, whereby the first body does not allow for airflow between the first and second major surfaces of the first body under normal atmospheric conditions;
• and
• a second body having a first major surface opposite a second major surface, whereby the second body allows for airflow between the first and second major surfaces of the second body under normal atmospheric conditions;
• wherein the first major exposed surface of the acoustic structural panel comprises a plurality of apertures adjacent to the second body.
