A glazing method and system for upgrading an existing single glazed window installation includes providing an insulating glass unit comprising a first glazing lite and a second glazing lite. Providing a spacer located between the existing lite and the insulating glass unit. The spacer is formed from a material which is capable of forming a seal between the insulating glass unit and the existing lite and forms a cavity between the insulating glass unit assembly and the existing glazing installation. Providing a supplemental holder for holding the insulating glass unit in place against the existing glazing installation.

What is claimed is: 1. A field installable glazing system for upgrading an existing glazing installation which comprises an existing window lite and sill, said glazing system comprising: an insulating glass unit comprising a first lite and a second lite; and an integrated spacer seal located between the existing lite and the insulating glass unit; and a fastener for mechanically securing the insulating glass unit in place; wherein the spacer seal is a tape further comprised of polyisobutyline, foam, desiccant and adhesive, said tape contacting only one side of the insulating glass unit. 2. The glazing system according to claim 1, wherein the tape is applied around the perimeter of the existing lite. 3. The glazing system according to claim 1, wherein the adhesive is on two exterior surfaces of the tape. 4. The glazing system according to claim 1, wherein the insulating glass unit is further comprised of a spacer seal between the first and second lites. 5. The glazing system according to claim 1, wherein the fastener applies a force against the sill for holding the window assembly in place and another force towards the existing window lite for compressing the spacer seal. 6. The glazing system according to claim 1, wherein the insulating glass unit is a pre-assembled assembly. 7. The glazing system of claim 1 wherein the polyisobutyline is on two exterior surfaces of the tape. 8. The glazing system of claim 1 wherein the desiccant is embedded within the foam. 9. The glazing system of claim 1 wherein one of the insulating glass unit includes a low emissivity coating on one of the lite surfaces. 10. A field installable glazing system for upgrading an existing glazing installation which comprises an existing window lite and sill, comprising: an insulating glass unit comprising a first glazing lite and a second glazing lite and a first spacer located between the first and second lites; a second spacer seal located between the existing lite and the insulating glass unit forming a seal between the insulating glass unit and the existing lite and forming a cavity between the insulating glass unit and the existing glazing installation; and a fastener for mechanically holding the insulating glass unit in place against the existing glazing installation, the fastener applies a force against the sill for holding the insulating glass unit in place and another force towards the existing window lite for compressing the second spacer; wherein the second spacer seal is a tape is a tape further comprised of polyisobutyline, foam, desiccant and adhesive, said tape contacting only one side of the insulating glass unit. 11. The glazing system according to claim 10, wherein the insulating glass unit is a pre-assembled assembly.
