Structural bonding composite

1. A glazing system comprising:

a fenestration unit having opposed first and second major surfaces;

a frame member having a first major surface facing the first major surface of the fenestration unit;

a structural bonding composite interposed between the first major surface of the frame member and the first major surface of the fenestration unit, the structural bonding composite comprising:

a compressible base member having a first adhesive layer applied to a first side of the base member to define a first structural adhesive surface bonded to the first major surface of the frame member and a second adhesive layer applied to a second side of the base member to define a second structural adhesive surface opposite the first structural adhesive surface and bonded to the first major surface of the fenestration unit; and

a reinforcement member secured to a portion of the base member to maintain a predetermined thickness of the base member against compression between the first major surfaces of the fenestration unit and the frame member, the predetermined thickness corresponding to a required face clearance between the first major surfaces of the fenestration unit and the frame member;

wherein the structural bonding composite independently provides a sufficient bond of the fenestration unit to the frame member without other fastening materials; and

wherein the reinforcement member comprises a spacer bonded to a lateral edge portion of the base member, the spacer including a first side engaging the first major surface of the frame member and a second side engaging the second major surface of the fenestration unit.

2. The system of claim 1 , wherein the spacer comprises a gasket.

3. The system of claim 2 , wherein the gasket comprises a pre-set gasket.

4. The system of claim 2 , wherein the gasket comprises at least one of rubber and thermal plastic.

5. The system of claim 1 , wherein the base member comprises at least one of silicone and acrylic.

6. The system of claim 1 , wherein the first and second adhesive layers comprise at least one of silicone and acrylic.

7. The system of claim 1 , wherein the frame member comprises at least one of aluminum and stainless steel.

8. The system of claim 1 , wherein the reinforcement member comprises a first reinforcement member, the system further comprising a second reinforcement member disposed within the base member.

9. The system of claim 8 , wherein the second reinforcement member comprises a rigid shim.

10. The system of claim 1 , wherein the fenestration unit comprises an insulation glass unit having a first glass panel defining the first major surface and a second glass panel defining the second major surface.

11. The system of claim 1 , wherein the frame member comprises a flange portion extending around a lateral edge of the fenestration unit and defining a second major surface facing the second major surface of the fenestration unit.

12. The system of claim 1 , wherein the structural bonding composite has a bonding tensile strength in accordance with ASTM C1401.

13. The system of claim 1 , wherein the structural bonding composite has a shear strength in accordance with ASTM C1401.

14. The system of claim 1 , wherein the predetermined thickness is about 0.25 inches.

15. The system of claim 1 , wherein the first and second adhesive layers comprise at least one of an addition-cured silicone, a radiation cured silicone, and a condensation cured silicone.

16. A glazing system comprising:

a fenestration unit having opposed first and second major surfaces;

a frame member having a first major surface facing the first major surface of the fenestration unit;

a structural bonding composite interposed between the first major surface of the frame member and the first major surface of the fenestration unit, the structural bonding composite comprising a compressible base member having a first adhesive layer applied to a first side of the base member to define a first structural adhesive surface bonded to the first major surface of the frame member and a second adhesive layer applied to a second side of the base member to define a second structural adhesive surface opposite the first structural adhesive surface and bonded to the first major surface of the fenestration unit; and

a reinforcement spacer secured between the first major surfaces of the fenestration unit and the frame member, adjacent to a first lateral edge of the base member, to maintain a predetermined thickness of the base member against compression between the first major surfaces of the fenestration unit and the frame member, the predetermined thickness corresponding to a required face clearance between the first major surfaces of the fenestration unit and the frame member;

wherein the structural bonding composite independently provides a sufficient bond of the fenestration unit to the frame member without other fastening materials.

17. The system of claim 16 , wherein the reinforcement spacer comprises a gasket.

18. The system of claim 17 , wherein the gasket comprises a pre-set gasket.

19. The system of claim 17 , wherein the gasket comprises at least one of rubber and thermal plastic.

20. The system of claim 16 , wherein the base member comprises at least one of silicone and acrylic.

21. The system of claim 16 , wherein the first and second adhesive layers comprise at least one of silicone and acrylic.

22. The system of claim 16 , wherein the structural bonding composite has a bonding tensile strength and a shear strength in accordance with ASTM C1401.

23. The system of claim 16 , wherein the predetermined thickness is about 0.25 inches.

24. The system of claim 16 , wherein the reinforcement spacer is bonded to the first lateral edge of the base member.

25. The sytem of claim 16 , wherein the first adhesive layer, the second adhesive layer, and the reinforcement spacer comprise silicone material.

26. The system of claim 16 , wherein the first and second adhesive layers comprise at least one of a radiation cured silicone and a condensation cured silicone.
