Aerogel containing construction board

A construction product comprising:

• a fiber core comprising a plurality of entangled glass fibers;
• a binder that bonds the plurality of entangled glass fibers together;
• and
• an Aerogel material homogenously or uniformly disposed within the fiber core;
• wherein:
• the fiber core includes between 40 and 80 weight percent of the Aerogel;
• the construction product has an R-value of at least 6.5 per inch;
• and
• the construction product has a flame spread index no greater than 5 and a smoke development index no greater than 20 as measured according to ASTM E-84 tunnel test.

A method of forming a construction product comprising:

• providing an aqueous solution that includes glass fibers and an Aerogel material homogenously or uniformly dispersed within the glass fibers;
• pouring the aqueous solution onto a porous surface;
• removing water from the aqueous solution to form a wet laid mat or material mixture of the glass fibers and Aerogel material atop the porous surface;
• applying a binder to the wet laid mat or material mixture;
• and
• curing the binder to bond the glass fibers and Aerogel material together and thereby form a fiber core of the construction product;
• wherein:
• the fiber core includes between 40 and 80 weight percent of the Aerogel;
• the fiber core has an R-value of at least 6.5 per inch;
• and
• the fiber core has a flame spread index of no greater than 5 and a smoke development index of no greater than 20 as measured according to ASTM E-84 test.
