Abstract
An insulating material consisting essentially of fly ash particles and a binder and a method for making the same. In one embodiment of the present invention, fly ash particles are mixed with a dissipating foam which contains a binder. The foam acts to spread the binder and separate the fly ash particles, thereby coating the fly ash particles with the binder. When the foam dissipates the binder acts to bind the fly ash particles together in clusters. The clusters of fly ash particles are then suitable to be used as blown-in insulation.
Claims11
A method for insulating a cavity, comprising:
- providing a plurality of fly ash insulating particles;
- supplying a binder, said supplying step including creating a foam material of a sufficient thickness and said supplying step including separating said insulating particles using said foam material;
- mixing said insulating particles dried to provide sufficiently dry clusters with each of said clusters drying a plurality of insulating particles, said having step including dissipating of said foam material while said insulating particles are located outside of the cavity to be filled with said insulating particles, said drying step being discontinued before said clusters collapse and lose desired separation of said insulating particles;
- containing said insulating particles while maintaining said insulating particles joined together in said clusters using said binder after having dried and before being placed in the cavity;
- and
- installing said clusters into the cavity after said foam material has dissipated.
