ROBER CURVED
Characteristics: CURVED GLASS
Description
Rober Curved Glass glass allows a vast array of applications, due to the wide range of thicknesses and laminations for a curved pane, and the possibility of vertical or horizontal product installation.
Suitable for both indoors and outdoors, curved panes can be used in architecture to construct verandas, skylights, domes, bus stop shelters, stairways and railings; For interior decoration, it can be used to construct tables, mirrors, aquariums, partitions, faux ceilings. With its own technical organization, Rober Glass is capable of considering the validity of any project proposal and suggesting solutions to particular technical problems.
The technical department of Rober Glass is available to discuss the realization of any idea and suggest solutions to specific problems.
Due to its vast experience in the sector, Rober Glass can make large quantities of curved forms available, to save on development costs of curved glass. The savings is significant on the production of one or more items.
For the manufacture of curved glass, it is possible to use any kind of glass on the market, with the exception of magnetronic glass. Therefore, items with different composition and lamination may satisfy any type of demand:
- plain glass with a thickness that varies from 3 to 12mm for applications where particular resistance and soundproof characteristics are not necessary (partitions, tables, shop windows, aquariums...)
- safety glass laminated with two or more panes with PVB interspace, for use in environments where impact-proof glass is necessary (railings, public transportation shelters, stairways, ticket windows, doors, elevators and elevator shafts, skylights…)
- bulletproof glass laminated with three or more panes with PVB interspace for use where protective and bulletproof security is necessary (glass doors and windows, bank entrances and teller windows, skylights…)
- insulated glass for use in environments that require soundproof and thermal insulation (windows, façades, ventilated façades, domes, skylights…)
- soundproof safety glass combinations of laminated safety glass with a thermal-acoustic chamber, (mainly used in banks, jewelry stores, insurance companies, hospitals, churches and in particularly noisy places)
- low-E glass combinations with special glass to limit solar rays; used on façades and external stairways for offices and stores
- low-E glass combinations with special glass to limit solar rays; used on façades and external stairways for offices and stores

Curvatures and shapes
Rober Curved Glass can be realized in a variety of curvatures and shapes, even in specific designs. Here are some examples.
The maximum set Fe possible is 600 mm.
The minimum radius of curvature varies according to the thickness of the glass (see table)
Lower radii can be developed upon request.
Curved glass can be realized in a variety of curvatures and shapes, even in specific designs.
The figure shows some of the most common types of curvatures and shapes.
Assemblage
To install curved glass, one must observe special assembly rules:
- avoid the transmission of mechanical pressure onto the edges of the glass, in order to prevent mechanical shock. For assembly on metal casements, it is advisable to make sure the structure is not subject to settlement before assembling;
- avoid tension or pressure deriving from thermal expansion
To install curved glass a superior tollerance is necessary with regard to the installation of flat glass.
For curved glass with thickness s <= 12 mm the encasement depth must be at least 25 mm, whereas for thickness s >2 mm the encasement depth must be over 30 mm.
For colored glass, the encasement depth must not be more than 25 mm, in order to avoid thermal shock.
The peripheral space must be over 10 mm.
Allowances
The allowances requested for the manufacture of curved glass are superior to those of flat glass and gradually increase according to the thickness of the glass.
The allowances on the radius are more sensitive and may exceed 6 mm, according to the degree of difficulty of the workmanship and the dimensions.
To determine the “installation width”, the relative allowances must be kept in mind, in order to avoid costly modifications of the doors and windows.
