1. A method for forming a tri-layer laminated window comprising: a) assembling a mold comprising two plies that make up a laminated window, the plies being a predetermined distance apart and the plies selected from glass, plastic, or one of each;b) filling the mold by a non-extrusion process with a
1. A method for forming a tri-layer laminated window comprising: a) assembling a mold comprising two plies that make up a laminated window, the plies being a predetermined distance apart and the plies selected from glass, plastic, or one of each;b) filling the mold by a non-extrusion process with a reaction mixture for forming a polymer material;c) adding one or more solar control components to the reaction mixtures while the polymer material is being formed, the solar control components selected from the group consisting of molybdenum dibutyl phosphate, hydroxyl phenyl benzotriazole, organometallic tungsten dyes, lanthanum hexaboride (LaB6) nanosized particles, and combinations thereof; andd) curing the reaction mixture to adhere the two piles together with a degree of adhesion in the range of 1 pound to 10 pounds per lineal inch, wherein the laminated window has a visible light transmittance of at least 70% and haze no greater than 0.5%, and wherein the reaction mixture forms an interlayer between the two plies. 2. The method according to claim 1, wherein the polymer material has a modulus of elasticity ranging from 500 psi to 200,000 psi. 3. The method according to claim 1, wherein the solar control components are selected from lanthanum hexaboride (LaB6) nanosized particles. 4. The method according to claim 3, wherein the nanosized particles are added to the reaction mixture in an amount ranging from 1 to 20 wt.% of the reaction mixture. 5. The method according to claim 1, wherein the solar color component is selected from organometallic tungsten. 6. The method according to claim 1, wherein the organometallic tungsten comprises dibutyl tungsten phosphate. 7. The method according to claim 5, wherein the organometallic tungsten ranges from 0.5 to 3 wt.% of the reaction mixture. 8. The method according to claim 1, wherein the solar control component is selected from molybdenum dibutyl phosphate. 9. The method according to claim 8, wherein the molybdenum dibutyl phosphate ranges from 0.5 to 4 wt.% of the reaction mixture. 10. The method according to claim 1, wherein curing the reaction mixture is accomplished by thermal curing, curing using ultraviolet light, or a combination of both thermal and ultraviolet light curing. 11. The method according to claim 1, wherein the polymer material comprises at least one of a polyurethane, a polyurethane acrylate, a polyacrylate, or mixtures thereof. 12. The method according to claim 1, wherein the solar control components are selected from organometallic tungston dyes prepared by reacting tungsten hexachloride with alkyl esters of phosphoric acid, wherein the organometallic tungsten dyes are UV stable. 13. A method for forming a multi-ply laminated window comprising: a) assembling a mold comprising two plies that make up a laminated window the plies being a predetermined distance apart and the plies selected from glass, plastic, or one of each;b) filling the mold by a non-extrusion process with a reaction mixture for forming a polymer material;c) adding one or more solar control components to the reaction mixture while the polymer material is being formed the solar control components selected from the group consisting of molybdenum dibutyl phosphate, hydroxyl phenyl-benzotriazole, organometallic tungsten dyes, and combinations thereof; andd) curing the reaction mixture to adhere the two piles together with a degree of adhesion in the range of 1 pound to 10 pound per lineal inch, wherein the laminated window has a visible light transmittance of at least 70% and haze no greater than 0.5%, and wherein the reaction mixture forms an interlayer between the two piles. 14. The method of claim 1, wherein the solar control components are selected from the group consisting of molybdenum dibutyl phosphate, organometallic tungsten dyes, and combinations thereof. 15. The method of claim 13, wherein the solar control components are selected from the group consisting of molybdenum dibutyl phosphate, organometallic tungsten dyes, and combinations thereof.
