Abstract
A structural bonding composite includes a polymeric base member, a first structural adhesive layer on a first side of the base member, a second structural adhesive layer on a second side of the base member opposite the first side, and a reinforcement member secured to a portion of the base member to maintain a predetermined thickness of the base member against compression applied to the first and second sides of the base member.
Claims56
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 structural adhesive surface bonded to the first major surface of the frame member and 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.
A structural bonding composite comprising:
- a polymeric base member;
- a first structural adhesive layer on a first side of the base member;
- a second structural adhesive layer on a second side of the base member opposite the first side;
- and
- a reinforcement member secured to a portion of the base member to maintain a predetermined thickness of the base member against compression applied to the first and second sides of the base member;
- wherein the first and second structural adhesive layers provide a bonding tensile strength and a shear strength in accordance with ASTM C1401.
In combination, a glass supporting frame member having a first major surface for supporting a fenestration unit, and a structural bonding composite, the structural bonding composite comprising:
- a polymeric base member;
- a first structural adhesive layer on a first side of the base member, the first structural adhesive layer bonding the first side of the base member to the first major surface of the frame member;
- a second structural adhesive layer on a second side of the base member opposite the first side;
- and
- a reinforcement member secured to a portion of the base member to maintain a predetermined thickness of the base member against compression applied to the first and second sides of the base member;
- wherein the first and second structural adhesive layers provide a bonding tensile strength and a shear strength in accordance with ASTM C1401.
A method of installing a fenestration unit, the method comprising:
- providing a frame member having a first major surface with a structural bonding composite adhered to the first major surface, the structural bonding composite including a polymeric base member, a first structural adhesive surface on a first side of the base member and bonded to the first major surface of the frame member, and a second structural adhesive surface on a second side of the base member opposite the first side;
- and
- adhering a first major surface of the fenestration unit to the second structural adhesive surface to permanently bond the fenestration unit to 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.
