Gypsum wallboard having multiple blended surfactants

A gypsum board, comprising:

• a set gypsum core disposed between two cover sheets;
• said set gypsum core comprising a gypsum crystal matrix formed from at least water, stucco, and a foam;
• said foam is formed from a blend of a first surfactant, a second surfactant and a third surfactant and water, wherein each said surfactant is independently supplied and is controlled via a designated user-operated control valve for blending and has a distinct composition from the other surfactants;
• said first surfactant is an alkyl sulfate;
• said second surfactant is an alkyl ether sulfate;
• and
• said third surfactant is an alkyl sulfate distinct from said first surfactant and having one of a head group chemistry and a carbon chain length different from said first surfactant and said second surfactant.

A process for producing low density gypsum wallboard panels, comprising:

• providing a first surfactant;
• providing a second surfactant;
• providing a third surfactant;
• wherein each of said first surfactant, said second surfactant and said third surfactant is a distinct composition from the other surfactants;
• each of said first surfactant, said second surfactant and said third surfactant are delivered independently by separate delivery tubes using user-operated control valves for each surfactant into a soap mixing tube;
• blending said first surfactant, said second surfactant and said third surfactant with water in said mixing tube to form foam;
• and
• blending said foam with a wallboard slurry for forming a low density gypsum wallboard.
