Frequently Asked Questions:

We apologize, but we are happy to provide our prices upon request. Please understand that every construction and every piece of glass is individual and requires different attention.

Glass in which a permanent surface compressive stress is induced by a specially controlled process of heating and cooling, in order to significantly increase resistance to mechanical and thermal stress while achieving prescribed breakage characteristics.

Due to the internal stress introduced during the thermal tempering process, when the glass breaks, it forms a large number of small, blunt fragments with a maximum size of 100 mm.

According to the definition of the EN 12543 standard, laminated and laminated safety glass is defined as an assembly consisting of one pane of glass and one or more panes of glass or flat glazing materials, bonded together by one or more interlayers.

Laminated glass also includes glass that has not achieved its fire resistance through interlayers that react to high temperatures (laminated glass with fire protection properties) and glass in which at least one interlayer reacts to high temperatures to provide the product with its fire resistance (fire-resistant laminated glass).

Insulating glass according to EN 1279 is a product consisting of at least two panes of glass, separated by one or more spacer frames, hermetically sealed around the perimeter, mechanically stable and durable.

Two types of glass can be classified as safety glass. One is thermally toughened safety glass manufactured according to EN 12150, and the second group includes laminated safety glass according to EN ISO 12543, up to the resistance class defined in EN 12600.

By degree of processing:

• rough ground glass edges
• fine ground glass edges
• matt ground glass edges
• polished ground glass edges

By shape of processing:

• bevels
• C-edge
• classic edge
• chamfered edge
• oblique edge

In order to correctly price the glass including installation, we need to know:

1. Where the glass will be placed and what it will be used for.
2. Glass dimensions.
3. Type of load and environment.
4. Method of mounting and anchoring.
5. Safety and functionality requirements.
6. Optical and visual requirements.
7. Maintenance and replacement method.
8. Hygiene and legislative restrictions.
