Glass Terminology

Rapsomanikis Glass

Glass: glass is a solid and amorphous material (shows no crystalline structure). It’s semi-transparent or transparent, brittle, inflexible and hard. Due to the lack of crystallinity, the term “glass” or “glassy” refers to all amorphous solids. The transparency regards to visible light because ordinary glass is opaque to UV radiation. As the material is chemically and biologically inert, fully recyclable and therefore, particularly suitable for use in manufacturing food and beverage packaging.

Bulletproof glass: Armoured glass, which has more than 60mm thickness and completely resists penetration by bullets.

Textured Glass: Semi-transparent glass made of clear or coloured glass that has passed between two rollers at the end of the oven and the relief plan is reflected in high temperatures in one or both sides of the glass from the relief rolls. It can be integrated with wire mesh in the mass of glass.

Security glass: Glass that does not crumble into sharp and potentially dangerous fragments when broken. Safety glass can be produced by machining TRIPLEX (see TRIPLEX) or by thermal curing (see tempering)

Glass Float: The excess glass is the product of sand and sodium carbonate heated to over 1500oC flowing over a bath of molten zinc.

Fire Glass: Plate glass with embedded wire mesh, which delays the rupture in case of fire delaying the spread of fire and smoke. Such glazing is classified as a Class G (to resist fire and prevent the spread of fire and smoke for a certain period). Such glazing is classified as a Class G (to resist fire and prevent the spread of fire and smoke for a certain period) or Class F (which has the characteristics of Class G, but also prevents the spread of radiant heat for a certain period). New developments include pre-stressed glass from boron silicon-free metal mesh – and double glazing the cavity space filled expanded material which acts as a heat shield.

Triplex (Expanded) glass: Glass triplex consisting of two or more sheets of glass with one or more layers of plastic viscosity between facades. The solid combination of spectacle takes place in an area called autoclaves sterilizer. In this furnace at a constant heating of layers of glass and plastic enabling the creation of plate glass (ie triplex). When laminated glass breaks, the pieces remain stuck inside plastic layer.

Tempered Glass: Glass which has submitted heat treatment to give a greater degree of mechanical and thermal resistance. The glass is heated to over 600° C and then cooled rapidly (complete cure) or slower (thermal support). In both cases with carefully controlled cooling rate. These processes make the glass surface on a permanent compressive tension giving the glass special features. Resistance to mechanical and thermal shock up to 2 times (thermally enhanced) or 5 times (thermally tempered) more than one ordinary glass. Protects the glass from breakage caused by high temperature difference on the surface of the glass (caused, for example, local shading). This is particularly important for glass types with high-energy absorption exposed to sunlight.

Only for thermally toughened glass: tempered glass, which breaks into small fragments with no sharp edges, ensuring protection against risks of injury. (Doors, furniture, transparent glazing in facades and skylights, any application that requires resistance to thermal and mechanical stress).

Thermally enhanced: No risk of breakage caused by nickel sulphate incarceration. Assay of heat soaking is not necessary. Improved surface flatness and less optical distortion compared to the thermally tempered glass (especially important for high reflectivity glazing in facades). Breaking into larger fragments with less risk of the glass to fall down. (Single glazing in roof lights, external and internal sheets of double glazing in skylights, exterior facades solar control double glazing with a high rate of energy absorption TRIPLEX glazed solar control).

The hardened and heat-strengthened glass can neither cut, nor formatted further.
