Glass types

IGLASS – standard glass

IGLASS - standard glass

Standard insulating glass is comprised of two or three sheets of float glass with a thickness of 3-10mm and and air pocket between the panes 6-24mm. The surface of the insulating glass can be optically split by the ornamental mesh located in the air space.

The thermal-insulating ability of the product is expressed by the value of the coefficient of heat conversion U (W.m-2.K-1). As compared with regular glass this insulating double-glass allows the heat loss to be reduced by 40-50%. If there is required either a high light permeability, or perhaps limiting the permeability, ornamental glass may be used in the structure of the insulating glass. Shapes of the insulating glass may be regular or irregular.

SOLARGLASS – antisolar insulating glass

SOLARGLASS – antisolar insulating glass

With a growing glass surface, there increases transillumination and warming of the interior influenced by the suns rays, which from the perspective of comfort in the environment might be to some extent unfavorable. These undesired features can be balanced with a special insulating glass.

If we replace on the standard insulating glass the outer clear pane of glass, with glass with a reflective absorbtive character, it halts the unfavorable effects of excessive sun rays.

A wide range of antisolar insulating types of glass exist, divided into three groups:

  1. Glass with an absorptive character, this is glass colored in material (planibel, parsol) in the colors bronze, green, grey, blue.
  2. Glass with a reflective and absorptive character (stopsol, antelio) in colors clear, bronz, green, grey, blue. Reflective effects can be regulated by orienting layers of metal oxides on the glass. Reflective effects are more evident when orienting layers on impingent rays. As long as the layer is oriented toward the air space of the insulating glass, the reflexion value is significantly reduced.
  3. Reflected glass with a heightened thermal insulation (stopray) ensures protection against the undesired entrance of solar energy and also markedly improves the thermo-insulating characteristics of double-pane. Value of the coefficient of heat transfer U < 1,3. The layer of precious metal on the surface of the glass must always be oriented toward the air space, as to not result in it being damaged.

THERMOGLASS – thermal-insulating glass

THERMOGLASS - thermal-insulating glass

Thermal-insulating glass lowers, in comparison with standard insulating glass, heat loss. If we replace in a standard window an inner pane of glass with low emissivity (the surface of the glass coated with a special metal layer), the heat tranfer can be markedly lowered. Another reduction of these values can be achieved by exchanging the air in the cavity of the insulating glass for gas with a low thermal conductivity. This insulating glass is distinguished by another interesting effect. High permeability in the visible section of the solar spectrum allows a relatively high transfer of solar energy into the place where the sun`s rays change to thermal, which by the tiny layer of metal oxide is transfered to the inner glass and reflected back. This increases heat gains over cooler periods.

To achieve even higher functionality and aethetic properties of this special insulating glass, the outer clear glass may be replaced with antisolar or safety glass.

SONORGLASS – sound insulating glass

SONORGLASS - sound insulating glass

Sound insulating glass are special insulating types of glass which lower the admittance of noise from the outside to the interior. From the perspective of acoustic characteristics of the glass, very often used is the magnitude index of sound Rw expressed in dB units. The Rw index determines the insulating ability element against sound spreading by air. Sound insulating glass is used to cover objects near rail lines, airports, intersections and the like.

Sound insulating characteristics are reached in double-glazed glass in several manners:

  1. Insulating double-glaze with asymetrical thickness of the window panes
  2. Filling with heavy gas
  3. Expanding the air space between the panes
  4. Using a layer of glass coated with resin
  5. Using a layer of glass with a special sound insulating foil

Sound insulating glass which has in its composition toughened glass can be used for safety purposes.

SECURGLASS – safety insulating glass

SECURGLASS - safety insulating glass

We acquire safety insulating glass by replacing regular glass with laminated glass, toughened glass, wired glass or by using safety metal mesh.

Kombinácia s vrstveným sklom:

Laminated glass lowers the risk of injuries, for the shards of glass remain within the plastic covering. Laminated glass protects against robbery and gunfire.

Combination with toughened glass:

Toughened glass is several times stronger than regular glass of the same thickness. It is used under stronger wind conditions and heat stress. Sharp shards do not result from its destruction.

Combination with glass with wire inlay:

Integrity of the glass is maintained under mechanical strain and the effects of fire.

Combination with metal safety mesh:

Metal mesh is inserted between panes of glass and has both safety and decorative functions.
