The invention relates to a noise-protection wall-segment, for example for roads, motorways or railways and such like, said noise-protection wall-segment including transparent sheets, preferably a transparent plastic sheets, and means fixing the sheets. The transparent sheet is shaped around a perpendicular to the installation surface of the assembled noise-protection wall, the term 'shaping' being understood to mean vaulting and/or folding. Moreover, in the case of plastic sheets, preferably made of acrylic glass, threads of synthetic material can be embedded in the sheet which counteract splintering in the event of fracture and constitute a recognized bird impact protection device.

Noise-protection wall-segment

A fireproof transparent pane panel is disclosed which comprises a plastic pane core disposed between panes of inorganic glass. Support elements in the form of plastic threads or strips, arranged unidirectionally or in a lattice, are embedded within the core.

Fireproof transparent pane panel

A light-admitting plastic sheet component is used for rigid roofing. PVC or PC is chosen as the material for the plastic sheet, and the side not exposed to weathering is coated with a non-combustible material that is resistant to flying sparks and radiant heat.

Light-admitting component as rigid roofing

Transparent plastic panels, particularly those used in noise-reducing barriers, are provided with bird-protecting means comprising plastic threads which are embedded by casting in the panels and are of such high-contrast that they can be seen by birds. The threads also prevent the panel from fracturing. Preferably the plastic threads are of black dyed polyamide and have a thickness of about 2 mm.

Transparent plastic panels having bird protection, and use thereof as

Noise-abatement panels of acrylic glass are secured against fragmentation by plastic threads, plastic bands or a plastic net embedded in them approximately in the middle. If the acrylic glass breaks, the threads, bands or nets hold the fragments together.
