insulating glass

Prázdny

The history of insulating glass began in 1865, when a patent was granted to Thomas Stetson in the USA. Since then, it has come a long way in development. Today, window panes are generally formed by two or more panes of glass, with a spacer frame, a cavity filled with air and inert gas and complemented by coatings with thermal insulation properties or special glazing.

PROPERTIES OF INSULATING GLASS

The current technological potential of glass production and processing does not limit the ideas of architects and builders. Window panes of various shapes and sizes are created. Large glass areas are popular, offering a visual connection of the interior with the surrounding world and bring a flood of natural daylight to our homes.

However, design is just one of the many requirements for panes placed on them by current trends. Thermal insulation and energy efficiency of glass play a key role here.

Windows that are overexposed to sunlight will require protection from the sun If you want to enjoy the silence, it will be necessary to look at sound insulating glass. Last but not least, safety must be taken into account, so that glass can also to some extent protect buildings from unwanted negative impacts.

The answer to these requirements is insulating glass, in the production of which different types of glass, coatings and foils are combined to achieve
the desired result.


THERMAL INSULATING
GLASS

It is important to focus not only on heat loss but also on heat gain. In the colder period, the glass does not let the cold into the interior and, thanks to a special layer on the inner glass, it turns the sunshine into heat, reflecting it back into the room.

We monitor the heat transfer coefficient of the glazing - UG. The lower its value, the better the thermal insulation properties of the glass.


GLASS WITH SUN
PROTECTION

Light without heat. This glass prevents the interior from overheating due to the exposure of sunlight to the window panes. It provides a combination of high transmission of natural light with sun protection.

We monitor the values of light transmission - LT. The lower its value, the more light is retained by the insulating glass.


SOUND INSULATING
GLASS

It protects against unwanted noise from the outside environment. It is used for glazing buildings with high exterior noise. It should be installed in the direction of the noise source. It is an excellent solution for houses near busy roads, railways, airports, etc. 

We monitor the values of sound insulation expressed in decibels - Db. The higher the number, the more effective the sound insulation.


FIRE GLASS

It protects people and property from fire and its spread. But thanks to its properties, it brings much more. It provides excellent sound insulation, sun protection and UV protection. Its use is necessary in the event of a potential hazard from a building or room in the event of a fire.


SAFETY GLASS

Thanks to the special treatment of the glass, it is possible to protect people from injury or falling and to protect property against burglary and vandalism. In the field of safety glass, it is possible to use mainly laminated safety glass and tempered glass, but also wire glass, or using safety bars.


ORNAMENTAL GLASS

Ornamentally decorated glass in various designs and with different transparency can also be combined into window frames. We offer models in clear and bronze. They find their application wherever it is desirable to create an intimate space without unwanted views from the outside, but with the preservation of the penetration of natural light.
 

COMPOSITION
AND GLASS MARKING

 

 

Double glazing

A - standard glass – float
B - spacer frame – TGI
C - plated glass in position 3
F
- cavity filled with air or gas

For example, the composition:

4 Float | 16 TGI | 4 LowE
A B C

The number in the composition notation expresses the thickness of the glass and the spacer frame in mm.

Triple glazing

A - plated glass in position 2
B - spacer frame – TGI
C
- standard glass – float
D
- spacer frame – TGI
E
- plated glass in position 5
F
- cavity filled with air or gas

For example, the composition:

4 LowE | 16 TGI | 4 Float | 16 TGI | 4 LowE
A B C D E

The number in the composition notation expresses the thickness of the glass and the spacer frame in mm.
