Construction products detail

With linearly supported glazing, the glass panes are continuously fixed via a linear mechanical glass support (e.g. profile) with a glass insertion depth. The glazing system is installed in such a manner that no constraint arises taking into consideration practical construction tolerances. Contact with hard components or other glass panes must be avoided. Linearly supported glazing is used in facades, in roofs, as canopies, as internal partitions or for photovoltaic systems.

Differentiation is made between vertical and horizontal glazing depending on the installation position. Glazing with an angle of inclination of 10° maximum with respect to the vertical plane is referred to as vertical glazing. Horizontal glazing is understood to be glazing with an angle of inclination of more than 10° with respect to the vertical plane.

Glass products requiring verification are primarily special glass products such as:

• Curved glass: Curved glass is curved (deformed) in a hot bending process. The simplest form is a cylinder. Spherically curved constructions are very rare and are not yet covered by the existing technical specifications.
• Other special glass products: The compositions of glass products can deviate from the harmonised European product standards (e.g. EN 572-9). An example of this is 'special drawn sheet glass'.

Regulatory framework

Linearly supported glazing is executed in accordance with DIN 18008-2. For construction techniques which deviate significantly from these provisions, DIBt grants general construction technique permits (aBG). For products used in the construction technique which are not covered by harmonised European standards, DIBt grants national technical approvals (abZ). European Technical Assessments (ETAs) can also be issued for these products.

Regarding this, please also note the relevant provisions of the federal states following MVV TB, A 1.2.7.
