Multiple glazed units Print E-mail
A multiple glazed unit is a combination of two or more glass sheets separated by an aluminum spacer, which is glued to the glass by a butyl tape to form a close chamber. The spacer bar is filled with a granular silica gel, which has the capacity to absorb the residual amount of moisture in the chamber. Important characteristics of modern glazing are: thermal transmittance (U-value), solar factor, light transmittance and, last but not least, sound insulation.
 
The great variety of glass on the market presupposes a great variety of multiple glazed units as well. Today’s energy efficiency requirements necessitate the use of LOW EMISSION GLASS (К GLASS) in the multiple glazed unit.


ADVANTAGES OF A MULTIPLE GLAZED UNIT WITH K GLASS:

• IMPROVES THERMAL INSULATION
• KEEPS THE HEAT INSIDE THE ROOM
• TRANSFORMS SUNLIGHT INTO AN ADDITIONAL HEAT SOURCE
• REDUCES ENERGY CONSUMPTION BY 40%

 

 

 

 

 

 

 

 

 

Thermal transmittance of the double glazed unit (Ug):

       -   from ordinary float glass with a thickness of 24 mm - Ug = 2.8  W/m2.K 
       -   combination with low emission glass with a thickness of 24 mm - Ug = 1.5 W/m2.K

In order to improve thermal insulation, the air inside the unit can be replaced by argon gas, which leads to a decrease in the thermal transmittance by 0.2-0.3 W/m2.K.

Types of glass:
• float, colorless and stained in their mass
• stopsol glass
• mirrors
• triplex
• toughened (reinforced) glass
• low emission glass
• ornament glass
• vitrail glass
