"Anti-reflective coating": Interference system for reducing the reflection on glass surfaces. The remaining reflection level at each glass surface is less than 1%

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

Colour-neutral Borosilicate glass with high temperature and chemical stability produced using a floating process.

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

Float glass with low iron oxide content to avoid the "green tint" of the glass.

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

Colour filter which can be used to modify the colour temperature of the light towards blue (colder) or red (warmer) or to carry out colour corrections. Is, e.g., used for product lighting.

Calculation of coating systems, sample production of coating solutions and systems in the laboratory with the goal of meeting new customer-specific requirements (order development).

Sol-gel coating method where the substrate is drawn out of the coating solution under constant conditions. Due to the effect of the air humidity, the sol becomes a gel, which is then transformed into a metal oxide via a tempering process.

Ethylene-vinyl acetate plastic: Intermediate layer in laminated safety glass.

Category of colour effect filters with medium colour saturation.

High-quality, transparent flat glass manufactured using the so-called "floating process".

Category of colour effect filters with low colour saturation.

Category of colour effect filters with high colour saturation.

Colour-neutral, adsorption-free, partially transparent mirrors with reflection of a certain percentage of light and transmittance of the rest.

Dichroic mirror, which reflects the IR part of the light but lets the visible radiation pass.

Partially toughened glass: Toughened flat glass with enhanced impact and bending strength. The breakage structure is similar to float glass.

Item made of at least two glass panels. The distance between the glass panels is ensured via spacers.

Heat insulating glass

Insulating glass with improved heat insulation characteristics through the application of low e-coatings and inert gases.

Sound insulating glass

Insulating glass consisting of two or more glass panels with expediently coordinated thicknesses and distances, filled with air or special gas mixes.

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

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.

Dichroic mirror, which reflects the IR part of the light but lets the visible radiation pass.

Infrared radiation (thermal radiation): invisible radiation that heats up absorbing materials.

Laminated safety glass consists of at least two flat panels, which are laminated together with a PVB intermediate layer.

Limited sizes of panels can be bonded on a glass plate truss through a special bonding process, thus achieving greater dimensions. Additionally, this technique enables the design of mosaics in different colours and sizes.

Polyvinyl butyral: Synthetic intermediate layer in laminated safety glass.

Synthetic intermediate layer in laminated safety glass.

Method for producing thin layers on glass substrates. The glass is dipped into different solutions of organic metal compounds and drawn out at a defined speed. The film on the glass surface is transformed into adhesive metal oxide layers in the subsequent thermal process. By varying the materials, the number of layers and the layer thickness (depending on the drawing speed), it is possible to adjust the optical effects of the layer systems.

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

Static effective adhesion of glass on a metal frame construction.

Optical filter that, when combined with a suitable light source, simulates the solar spectrum to the best possible degree. Application: for electrical characterisation of photocells and material testing.

Thermal tempered glass whose impact and bending strength is enhanced through a strengthening process. Tempered glass will shatter into blunt-edged pieces in case of destruction.

Enhancement of the mechanical and thermal strength of the glass through thermal treatment (heating up, followed by fast, defined cooling down).

Heat transfer coefficient: Measuring unit for the heat lost through the glazing. Is specified in W/sqm K.

It is differentiated between UV absorbing and UV reflecting filters.

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

Ultra Violet range: 200-380 nm; VISible range VIS: 380-780 nm; Near (short wave) InfraRed NIR: 780-3000 nm.
