Low emission glass
Thermal comfort thanks to perfect thermal insulation.
Solar heat gains in wintertime or protection against heat in summertime
In winter
Thermal protection is the basic task of glazing units designed for windows. Thanks to our partnership with suppliers, resulting in development of new glass coats, PRESS GLASS is able to offer glass panes with even lower heat transfer coefficient Ug= 0,4 W/m2K. This value is close to the value of heat transfer coefficient of walls. Cold feet near the window are in the past.
All the people who want to save on heating in winter thanks to solar heat gains from the sunlight coming through window panes and are not concerned with overheating in summer, can now purchase heat insulating window panes with increased coefficient g=73%.
In summer
In summer the sun emits much large quantities of thermal energy, as compared with winter. Overheating is observed, mostly due to heat transfer through window panes. The grade of summer overheating protection is expressed in coefficient g. Its lower value defines better efficacy of the protection against overheating.
Our offer of heat-insulating glass panes includes also such structures that reduce the overheating effect with coefficient g=37%. Today the technology so far reserved for facades can be also be used in all houses. Now everybody can improve their thermal comfort while reducing the operating costs of mechanical air conditioning system installed. It is worth to remember that costs of cooling the premises are higher than costs of heating.
Design
One chamber heat insulating glazing unit comprises two glass panes, including one Thermofloat glass pane with invisible layer of inert metals combination (so-called “low emission layer”). Two chamber heat insulating glazing units comprise two Thermofloat glass panes.
The space between glass panes is filled with argon or krypton gas, which further reduces heat transfer coefficient Ug. Protection against gas leak at the glass pane perimeter is ensured by warm distance frame with two-step sealing of plastic.

PERFECT HEAT INSULATION OF GLASS PANE EDGE
We recommend using warm distance frame bent in corners, acc. to EN ISO 10077, with heat insulating glass panes.
Application of a warm frame improves heat insulating properties on edges, resulting in increase in glass pane temperature in that area and reduction in temporary condensation of vapour.
LONG LIFE WITH TIGHTNESS CERTIFICATE ACC. TO EN 1279
The basic criterion considered when assessing glazing units should be tightness, preventing ingress of moisture and gas leaks. The distance frame on glass panel perimeter should be bent, in order to ensure such tightness parameters acc. to standard EN 1279 in force.
Cutting and joining of frames reduces glass pane tightness and accelerates degradation of heat insulating properties. Glazing units with frames cut in corners can fail to meet the tightness requirement acc. to EN 1279.
ADVANTAGES
Optimal temperature in rooms
The level and distribution of air temperatures has a significant impact on our comfort while indoors. Until recently it was possible to feel a dramatic drop in temperature near a window during the winter, which could produce a strong feeling of discomfort. Thanks to the application of thermally insulated glass which amounts to 70% of the window surface it is possible to eliminate this problem the range of temperatures are not subjected to any heat discomfort.
A different problem can arise in the summer, when the sunrays overheat the inside of a building. This problem can be rectified by reflexive solar control and selective solar control glass which, thanks to its special construction, limits overheating while maintaining a high level of light transmission. A similar function is also provided by thermal control glass, but to a lesser degree; this is compensated by the benefit of higher heat retention performance during winter that thermal control glass offers.
High level of light transmission
One of the particularly important qualitative characteristics of glass is light transmission. This has a particular influence on the well-being of people who use the room in question.
As research shows, poor light transmission into a room can be the cause of a bad frame of mind. PRESS GLASS pays particular attention to this characteristic when preparing a market offer.
Reducing the costs of heating
Everyone who receives the heating bill wonders about ways to reduce such expenses. At present economizing on heat energy is the main task which faces producers of double-glazed units.
PRESS GLASS perfectly understands these needs and offers a few solutions thanks to which it is possible to significantly reduce the costs incurred when heating a building.
