Structural subfloor product and method of manufacturing same

A flooring system comprising:

• a plurality of flooring products, each flooring product comprising:
• a first oriented strand board comprising:
• a first surface;
• a second surface opposite the first surface;
• a first profiled edge;
• a first stepped section, where the first profiled edge is angled inwardly and extends from the second surface of the first oriented strand board to the first stepped section;
• a second profiled edge opposite the first profiled edge;
• and
• a first recessed section, where the second profiled edge is angled inwardly and extends from the second surface of the first oriented strand board to the first recessed section;
• a second oriented strand board comprising:
• a first surface;
• a second surface opposite the first surface;
• a third profiled edge;
• a second stepped section, where the second profiled edge is angled inwardly and extends from the second surface of the second oriented strand board to the second stepped section;
• a fourth profiled edge opposite the third profiled edge;
• and
• a second recessed section, where the fourth profiled edge is angled inwardly and extends from the second surface of the first oriented strand board to the second recessed section;
• an acoustic barrier layer positioned between the first oriented strand board and the second oriented strand board, where a first surface of the acoustic barrier layer is secured with adhesive to the first surface of the first oriented strand board and a second surface of the acoustic barrier layer is secured with adhesive to the first surface of the second oriented strand board;
• wherein, upon the securing of the acoustic barrier layer to the first oriented strand board and the second oriented strand board, the first stepped section and the second stepped section are arranged to form a tongue where the acoustic barrier layer extends from the tongue to form a first rounded bulge, and the first recessed section and the second recessed section are arranged to form a groove where the acoustic barrier layer extends into the groove to form a second rounded bulge;
• wherein, when two flooring products are assembled such that the tongue of a first flooring products is inserted into the groove of a second flooring product, the first rounded bulge of the first flooring product is in contact with the second rounded bulge of the second flooring product.
