Abstract
A wing profile has a glass package including several glass plates, wherein the wing profile has a reinforcement element made of plastic, which substantially is mounted on the wing profile below the entire support surface of the glass package. Between the reinforcement element and the glass package, a cohesive connection is provided by a plurality of adhesive elements.
Claims15
A sash profile comprising:
- a glass packet comprising a plurality of glass plates,
- a reinforcing element which is composed of polymer, and
- at least two adhesive elements,
- wherein the reinforcing element is installed at least partially under an entire contact area of the glass packet on the sash profile,
- the at least two adhesive elements are sandwiched directly between the reinforcing element and the glass packet to form a substance-to-substance join between the reinforcing element and the glass packet,
- the at least two adhesive elements have an E modulus of at least 100 N/mm2, measured at 23° C. and 50% relative atmospheric humidity, and
- the at least two adhesive elements are based on a free-radically curable two-component acrylate or methacrylate adhesive composition.
