Certain example embodiments relate to improved spacers for insulated glass units. Certain example embodiments relate to corrugated spacers that extend around a periphery of an IG unit. In certain example embodiments, the spacer includes at least one structured concave cavity. When positioned in conjunction with a substrate, the cavity may be filled with a sealant. In certain example embodiments, the sealant may be a thermoplastic sealant. In certain example embodiments, another cavity may be provided that may accept a structural sealant. In certain example embodiments, the thickness of the corrugated faces of a spacer may be less than the thickness of the shoulders of spacer.

1. An insulated glass unit, comprising: first and second substantially parallel, spaced apart glass substrates, the first and second glass substrates defining a gap therebetween;a spacer provided in the gap and around a periphery of the first and second substrates, the spacer including: first and second substantially parallel portions that are corrugated or undulate along the periphery, andfirst and second non-linear shoulders that connect the first and second substantially parallel portions forming a hollow enclosed area, each of the first and second non-linear shoulders being structured to form at least one concave cavity between itself and its respective glass substrate; anda first sealant material including a desiccant and disposed within each concave cavity and structured to form an edge seal between the spacer and the first and second substrates along the periphery of the first and second substrates. 2. The insulated glass unit of claim 1, wherein the first and second non-linear shoulders include one or more roll-formed corrugations that undulate in a direction substantially transverse the undulations of the first and second substantially parallel portions. 3. The insulated glass unit of claim 1, wherein the hollow enclosed area does not include a desiccant. 4. The insulated glass unit of claim 1, wherein each concave cavity is a semi-circular concave cavity. 5. The insulated glass unit of claim 4, wherein a size of each semi-circular concave cavity corresponds to a desired amount of the first sealant material. 6. The insulated glass unit of claim 5, wherein each of the first and second non-linear shoulders is structured to form the semi-circular concave cavity and a partial concave cavity between itself and its respective glass substrate. 7. The insulated glass unit of claim 6, wherein the first sealant material is also disposed within the partial concave cavity, and wherein the first sealant material is a structural thermoplastic sealant (TPS) material that includes the desiccant and that both forms the edge seal and creates a structural bond between the spacer and the first and second glass substrates. 8. The insulated glass unit of claim 7, wherein the structural TPS material including the desiccant is arranged in a layout that creates a path that extends at least one of moisture and gas diffusion. 9. The insulated glass unit of claim 8, wherein the path functions by extending effective permeation distances of at least one of moisture in and gas fill out. 10. The insulated glass unit of claim 6, wherein the first sealant material is a thermoplastic sealant (TPS) material that includes the desiccant, and further comprising a second sealant material disposed within each partial concave cavity, wherein the second sealant material is different than the TPS material and that creates a structural bond between the spacer and the first and second glass substrates. 11. The insulated glass unit of claim 10, wherein the second sealant material is skim coated around the periphery. 12. The insulated glass unit of claim 10, wherein each semi-circular concave cavity is in fluid communication with its respective partial concave cavity. 13. The insulated glass unit of claim 12, wherein the TPS material including the desiccant is arranged in a layout that creates a path that extends at least one of moisture and gas diffusion. 14. The insulated glass unit of claim 13, wherein the path functions by extending effective permeation distances of at least one of moisture in and gas fill out. 15. The insulated glass unit of claim 2, wherein the one or more roll-formed corrugations define the concave cavity and a partial concave cavity between each of the first and second shoulders and their respective glass substrates. 16. The insulated glass unit of claim 15, wherein the first sealant material is also disposed within the partial concave cavity, and wherein the first sealant material is a structural thermoplastic sealant (TPS) material that includes the desiccant and that both forms the edge seal and creates a structural bond between the spacer and the first and second glass substrates. 17. The insulated glass unit of claim 16, wherein the structural TPS material including the desiccant is arranged in a layout that creates a path that extends at least one of moisture and gas diffusion. 18. The insulated glass unit of claim 17, wherein the path functions by extending effective permeation distances of at least one of moisture in and gas fill out. 19. The insulated glass unit of claim 15, wherein the first sealant material is a thermoplastic sealant (TPS) material that includes the desiccant, and further comprising a second sealant material disposed within each partial concave cavity, wherein the second sealant material that is different than the TPS material and that creates a structural bond between the spacer and the first and second glass substrates. 20. The insulated glass unit of claim 19, wherein each concave cavity is in fluid communication with its respective partial concave cavity. 21. The insulated glass unit of claim 20, wherein the TPS material including the desiccant is arranged in a layout that creates a path that extends at least one of moisture and gas diffusion. 22. The insulated glass unit of claim 21, wherein the path functions by extending effective permeation distances of at least one of moisture in and gas fill out.
