GLASS WITH CERAMIC PRINT IN THE ARCHITECTURE

New technological innovations of Glas-Tech S.A.

Glas-Tech S.A. has started the first in Poland and one of the few in the world industrial technology employing direct, colorful printing on glass using ceramic inks. Using this unique method allows to subject glass with ceramic print to the tempering process and to other kinds of heat treatment. As a result we get a product that can be used for elevation as well as for lamination or double glazing in units. The produced coating is durable and weatherproof.

Digital print provides new, unlimited possibilities of creating colorful patterns on glass maintaining toughness and others properties of the tempered glass. This technology allows to make unique patterns on the facades (e.g. decoration of facade, limited insulation indoors, large format printing), inside glazing, indoor refurbishment as well as glass for all means of transport.

Only an image file is necessary to produce digital overprint on glass.

SPECIFICATION:

• resolution up to 360 dpi
• hardening-proof printing inks
• printing size: max 4200 mm x 2400 mm, min 200 mm x 300 mm
• thickness of glass to be processed- from 3mm to 19mm
• acceptable image files’ formats : PDF, PS, EPS, TIFF, BMP, JPG

TEMPERED GLASS – ESG

Tempering is a process of thermal treatment during which the glass is heated to the temperature above its annealing point and then it undergoes a very rapid cooling. The purpose of this treatment is to create balanced internal stresses in the glass sheets. It increases their mechanical strength up to about 5-7 times when compared with the normal glass.

When broken, tempered glass (also called safety glass) crumbles into small particles, which reduces the risk of injury. The following types of glass can be tempered: float, tinted glass, selective glass, solar control glass, low emission glass, sand-blasted glass, chemically etched glass, ornamental glass, and glass with ceramic coating. We offer tempering of glass of the following thickness: 3, 4, 5, 6, 8, 10, 12, 15, 19 mm.

Toughened glass has increased resistance to mechanical factors as well as to the stresses associated with temperature changes in sheet. Grinding, drilling holes, and imposing silk screen printing or enamel coating has to be made before tempering process.

SEMI-TEMPERED GLASS – TVG

Semi-tempered glass – TVG, also called heat strengthened glass, is produced in a similar process to tempered glass- ESG, but it requires a longer cooling time. Semi-tempered glass differs from the tempered glass in the kind of cracking patterns which appears during glass panel damage. The glass stays in a frame when broken. It reduces the risk of injury.

However, semi-tempered glass is not the same as safety glass.

HEAT-SOAK-TEST – HST

During the manufacturing process of float glass, when glass mass is poured into special tanks, a risk that nickel sulfate can precipitate may appear. It can cause an increase of residual stresses in glass, which lead to accidental ruptures. This occurs rarely, but glass used for structural components has to be safe. Consequently, tempered glass should be subjected to HST during which the panes of glass containing nickel sulfate are eliminated from the supply.

Tempered glass is offered in products:

• safety glazed units
• glass for land and maritime transport
• solar control glass
• glass for structural and semi-structural glazing
• glass with ceramic silk screen-printing
• roller coated glass
• structural glass such as roofs, stairs, floors, fin glazing
• spider glass
• decorative glass e.g. crash-glass
• internal glazing (walls, doors)
• glass for shower cabins
• glass for home appliance and furniture

LAMINATED GLASS – VSG

Laminated glass consists of two or more layers bonded by an interlayer of polyvinyl butyral resin (PVB) or ethylene-vinyl acetate (EVA) using heat and pressure. If laminated safety glass gets broken, the fragments will adhere to the interlayer and generally they will not change their position which reduces the risk of injury.

Glass and interlayers may have different colors and thickness and they are designed to meet the standards and requirements of building regulations.

All kinds of glass can be used for lamination. The properties of different interlayers provide safety and protection against burglary, explosives and explosive shock wave, sound insulation etc. To increase the resistance of laminated safety glass, tempered glass (ESG) or semi-toughened glass (TVG) can be used.

We offer laminated glass in the following products:

• laminated safety and anti-burglar glass
• bulletproof glass
• decorative glass
• soundproof glass
• glass for land and maritime transport
• glass resistant to explosives and explosive shock wave
• glass for structural and semi-structural glazing
• spider glass
• structural glass like roofs, stairs, floors, fin-glazing

GLAZED UNITS

A double glazing glass unit consists of at least two panes of glass. Their edges are glazed and sealed by a spacer bar and internal insulation, which creates a closed space between the panes.

Glazed units are the most effective method of reducing heat flow through the glass. The energy efficiency of glazed glass is better when it is combined with low emission glass or/and selective coated glass. Following the increase in the effectiveness of low emission coatings to reduce heat flow, the efforts are made to improve the properties of spacer bars. Currently aluminum spacers are replaced with “warm edge” spacers that reduce heat loss.

Important! Value “U” of a window represents the heat transfer coefficient, that is the range to which the windows keep the room warmth. The heat transfer coefficient has the SI unit in Watts per squared meter (of the glass) -Kelvin: W/(m2K). The lower the U value, the better the insulation value of the glass. So called „low emission glass” has improved thermal insulation, expressed by very low value of U.

At present, basic low emission units have U=1,1 [W/m2 K] and the lowest heat transfer coefficient for tripple glazing is = 0,5 [W/m2 K].

Glazed glass is divided of the basis of its functions:

• low emission glass
• safety and antiburglar glass
• acoustic glazed units
• decorative glass
• solar control glass
• glass for structural and semi-structural glazing
• fire-resistant glass
• glazed units- Spandler- with ceramic enamel
• units for spider glazing
• glazed units with self-cleaning cating
