What is claimed is: 1. A variable length plastic wall tie for connecting and separating sheet materials used in casting a concrete wall, comprising: a male part and a female part of the wall tie, the male part having a body having two spaced apart flanges for receiving an insulating sheet, and having a distancing member spaced apart from said two spaced apart flanges and having a neck extending therefrom, said neck being axially slidable in said female part by fitting into an aperture in the female part of the tie, said neck of said male part having two generally parallel surfaces provided with a plurality of male teeth thereon; and wherein said aperture in the female part is provided with two pawls on opposite sides of said aperture, said pawls being positioned to engage with said male teeth of said neck to retain said male part a selected distance from female part, and the female part having two spaced apart flanges for receiving an insulating sheet, and having a distancing member spaced apart from said two spaced apart flanges, and the neck of the male part having wall thickness measurements indicated thereon, the separation of the male part and the female part being adjustable to provide a desired wall thickness by axial sliding movement of said neck of said male part in said aperture of said female part to a separation indicated by the wall thickness measurements. 2. The tie of claim 1, wherein said tie comprises one or more of 90° angled ties, 135° angled ties, and T-shape cross ties. 3. The tie of claim 1, wherein said ties are fabricated from polypropylene. 4. The tie of claim 1, wherein the separation of the male part and the female part is adjustable to provide a desired wall thickness of between 14 to 60 cm. 5. The tie of claim 1, wherein said tie comprises a straight tie. 6. The tie of claim 1, wherein said female part has a first set of two pawls located on opposite sides of said aperture, and a second set of two pawls axially separated from said first set of two pawls and on the same opposite sides of said aperture. 7. A wall assembly, comprising: a plurality of sheet materials held in position by a plurality of variable length plastic wall ties, said wall ties each having a male part and a female part of the tie, the male part having a body having two spaced apart flanges for receiving an insulating sheet, and having a distancing member spaced apart from said two spaced apart flanges and having a neck extending therefrom, said neck having two generally parallel surfaces, and said two parallel surfaces are both provided with a plurality of male teeth thereon, said neck being axially slidable in an aperture in said female part by fitting into the aperture in the female part of the tie, said aperture in the female part having two pawls on opposite sides of said aperture, said pawls being positioned for ratcheting engagement with said male teeth of said neck to retain said male part a selected distance from the female part , the female part having two spaced apart flanges for receiving an insulating sheet, and having a distancing member spaced apart from said two spaced apart flanges and the neck of the male part having wall thickness measurements indicated thereon, the separation of the male part and the female part being adjustable to provide a desired wall thickness by axial sliding movement of said neck of said male part in said aperture of said female part to a separation indicated by the wall thickness measurements. 8. The wall assembly of claim 7, further comprising concrete located between the sheet materials. 9. The wall assembly of claim 7 wherein said ties comprise one or more of 90° angled ties, 135° angled ties, and T-shape cross ties. 10. The wall assembly of claim 7, wherein said sheet materials are foam insulation. 11. The wall assembly of claim 7, wherein the separation of the male part and the female part is adjustable to provide a desired wall thickness of between 14 to 60 cm. 12. The wall assembly of claim 7, wherein said tie comprises a straight tie. 13. The wall assembly of claim 7, wherein said female part has a first set of two pawls located on opposite sides of said aperture, and a second set of two pawls axially separated from said first set of two pawls and on the same opposite sides of said aperture. 14. A variable length plastic wall tie for connecting and separating sheet materials used in casting a reinforced concrete wall, comprising: a male part having a body with three flanges extending therefrom, two of said flanges being axially separated a sufficient distance to receive and retain an insulation foam sheet material, and one of said flanges being a distancing member spaced apart from the other two flanges, and a neck extending from said body, said neck having two generally parallel surfaces, said two parallel surfaces being both provided with a plurality of male teeth thereon; a female part having three flanges extending therefrom, two of said flanges being axially separated a sufficient distance to receive and retain an insulation foam sheet material, and one of said flanges being a distancing member spaced apart from the other two flanges, and an aperture shaped to receive said neck of said male part; said aperture having two opposing aperture walls provided with pawls adapted to engage said male teeth of said neck; said neck being axially slidable in said aperture and female part by fitting into an aperture in the female part of the tie, said neck of said male part at least one side thereof, and said aperture in the female part being provided with one or more pawls for ratcheting engagement with said male teeth to hold said female part in position relative to said male part, and the neck of the male part having wall thickness measurements indicated thereon; the separation of the male part and the female part being adjustable to provide a desired wall thickness by axial sliding movement of said neck of said male part in said aperture of said female part to a separation indicated by the wall thickness measurements. 15. The tie of claim 14, wherein said tie comprises a straight tie. 16. The tie of claim 14, wherein said tie comprise one or more of 90° angled ties, 135° angled ties, and T-shape cross ties. 17. The tie of claim 14, wherein said female part has a first set of two pawls located on opposite sides of said aperture, and a second set of two pawls axially separated from said first set of two pawls and on the same opposite sides of said aperture.
