Description

"Mosaic" assembling

Limited sizes of plates can be bonded on a glass plate truss through a special bonding process. This technique enables the design of mosaics in different colors and sizes.

Absorption free dichroic filter, dichroic glass  Interference-coated glass, with light transmission for certain wavelength ranges (one certain color) and reflection of the remaining ranges. The color effect of the filter varies with the wave angle.
Achromatic beam splitter Color neutral beam splitter (grey filter) with reflection for a certain percentage of light and transmittance of the rest.

AR-coating

Abbreviation for anti-reflective-coating.

Argon / Krypton

Inert gas for the enhancement of heat insulation by insulation glass.

Borofloat

Color neutral borosilicate glass produced in a floating process and with high temperature and chemical stability.

Chemical strengthening

Enhancement of the mechanical and thermal strength of the glass by a special salt bath treatment.

Cold light mirror

Dichroic mirror, which reflects the visible part of the light and lets heat radiation pass.

Conversion filter

Color filter with which the color temperature of the light can slightly be modified towards blue (warmer) and red (cooler).

Dichroic glass

See absorption free dichroic filter

FE-types

Category of color effect filters with a medium color saturation.

Float glass

High quality, transparent soda lime flat glass manufactured in the so called "float process".

FS-types

Category of color effect filters with a high color saturation.  

Heat strengthened glass

Toughened flat glass with enhanced impact and bending strength. The breakage structure is similar to float glass but is more difficult to break.

Insulating glass

Item made of at least two similar or unlike glass sheets. The air space will be determined trough spacers between the glass panels.

- Heat insulating glass

  Insulation glass with improved heat insulation characteristics through   

  low-e-coatings and inert gas.

- Sound insulating glass

  Insulation glass consisting of two or more glass sheets with expedient

  coordinated thickness and distance, filled with air or special gas.

Interference

Interaction of two light beams, where - depending on the relation between them - amplification or annihilation results.

Interference principle, interference layer technology

Transparent thin layers with certain thickness and optical features are applied in a special sequence on a glass substrate. The reflected light fractions of the individual layers interfere with each other which leads to amplification or reduction of certain wavelength ranges - depending on the layer system design.

IR-light

Abbreviation for infrared radiation (thermal radiation). Invisible light, which is to heating up absorbing materials.

Laminated safety glass

Consisting of at least two flat sheets, which are laminated together with a PVB-intermediate layer(s).

Low iron glass

Float glass with low iron oxide content, thereby no "blue/green color".

PVB (=Polyvinyl-Butyral)

Synthetic intermediate layer in laminated safety glass.

Sol-Gel-Dip-coating

Production process for thin film layer on large surfaces of glass panels. The glass is dipped into different solutions of metal compounds and drawn out with defined speed. The film on the glass surface is transformed into a metal oxide layer in the following heating process. By variation of the material and the layer thickness, the optical effect of the system can be tailored.

Step insulating glass

Insulation glass unit, which shows an excess length of the panels. Especially used by bevelled and overhead conveyor glazing.

Structural glazing

Static effective adhesion of glass with a metal frame construction, also glass

Tempered or toughened glass

Thermal tempered flat glass, which enhances its impact- and bending strength through the strengthening process.

Thermal tempering

Enhancement of the mechanical and thermal strength of the glass by a temperature cycle (heating up, then fast cooling down); glass breaks into particles.

UV-, VIS- and NIR- range

Abbreviations for ultra-violet range UV: 200-380 nm; visible range VIS: 380-780 nm; near (short wave) infrared NIR: 780-3000 nm

U-value (heat transfer coefficient)

Measuring unit for the heat lost through the glazing. The designation occurs in W/sqm K.

UV-filter edge

Characteristic wavelength for the crossover from the exclusion range (ultraviolet) to the transmission range (longer wavelength) of the filter where the transmission is 50%.
