Abstract
A method of making a coverboard or wall sheathing, by mixing polyiso waste particles with polymer binder particles, wherein the ratio by weight of polyiso waste to polymer binder is between 1:15 to 1:1, wherein the polyiso waste particles are between 0.01-10 mm in diameter, and wherein the polymer binder particle are between 0.02-5 mm in diameter.
Claims20
A method of making a building product, comprising:
- mixing polyiso waste particles with polymer binder particles, wherein the ratio by weight of polyiso waste to polymer binder is between 1:15 to 1:1, and wherein the polyiso waste particles are between 0.01-10 mm in diameter, and wherein the polymer binder particle are between 0.02-5 mm in diameter;
- placing the resulting mixture into a mold or onto a belt press;
- applying heat to the mixture;
- applying pressure to the mixture;
- and then
- removing the mixture from the mold or press equipment and then allowing it to cool.
