Claims15
A sash profile having a glass packet comprising a plurality of glass plates, wherein the sash profile has a reinforcing element which is composed of polymer and is installed essentially under the entire contact area of the glass packet on the sash profile, where a substance-to-substance join between the reinforcing element and the glass packet is provided by means of at least two adhesive elements and the adhesive elements have an E modulus in accordance with ISO 37 (at 23° C. and 50% relative atmospheric humidity) of at least 100 N/mm2.
A method comprising applying a combination of adhesive elements and a reinforcing element for improving the flexural strength of a sash profile, wherein a glass packet is joined by substance-to-substance bonding via the adhesive elements to the reinforcing element arranged on the sash profile and the adhesive elements have an E modulus in accordance with ISO 37 (at 23° C. and 50% relative atmospheric humidity) of at least 100 N/mm2.
