Insulating glass windows Douglass


Insulating glass for thermal and acustic insulation

Insulating glass windows are made up of two or more glass sheets within which air is immobilized making possible scarse thermal conductivity.

The sheets are united to each other by means of a metallic or polymeric  space frame and are separated by a layer of air or noble gases.

Within the frame dehydrated salts are inserted which are needed to eliminate any trace of vapour created within the cavity assuring maximum transparency and avoiding any type of condensation phenomenon.

The glass window perimeter is then sealed with a polysulphide  barrier which avoids water vapour formation and then is fixed together with an ulterior silicon barrier.

Advanages regarding insulating glass windows

  • Elimination of cold areas with the room
  • Condensation reduction
  • Heat saving costs
  • Air conditioning saving costs
  • Co2 emission reduction
  • Radical external noise reduction.

Glazing glass functioning

Ug Value:  This indicates thermal transmitting. This means that the average heat flux which goes through the glass which separates two rooms having different temperatures.

g Value: This represents the relation between total energy transmitted within the room in which the glass window is found and the solar energy impact on that glass window.
