Insulation material and method of making same

An insulation material formed of a composition, the composition comprising:

• magnesium oxide;
• at least one of magnesium chloride, magnesium sulfate, and hydrates thereof;
• water;
• a foaming agent;
• a thickener;
• and
• a foam stabilizer
• wherein the foaming agent is an alkyl ammonium chloride;
• optionally the foaming agent has a concentration of 5 wt % of the water content.

A method of manufacturing an insulating material, the method comprising:

• providing a solution comprising:
• at least one of magnesium chloride, magnesium sulfate, or hydrates thereof;
• a foaming agent;
• a thickener;
• a plurality of polymer fibers;
• a foam stabilizer;
• and
• water;
• foaming the solution with a gas to provide a foamed mixture;
• optionally adding additional MgCl2 to the foamed mixture;
• providing a cement component mixture comprising:
• MgO;
• at least one of MgCl2;
• MgSO4;
• H2O;
• mixing the cement component mixture with foamed mixture to form a cementious mixture, wherein the mole ratio of magnesium oxide, magnesium chloride, and water in the cementious mixture is 5-12:1:14-31, wherein the mole ratio includes hydrates;
• and
• curing the cementious mixture.
