Insulated glass (Double /Triple Insulated Glazed Glass Panels)are hermetically sealed combinations of two or more panes of glass separate by a dry airspace. The air trapped between the two pieces of glass acts as an insulator slowing the rate at which heat and cold can pass through the unit. The more air sandwiched between the glass,the better insulator effect you have.

 

 

  

Double insulating glass is obtained by sealing two panes of glass separated by an aluminum spacer rod of different thicknesses, with small perforations to the inside and were silica was inserted (an amorphous silicate, made of small granules, that acts like a sponge, having a large capacity to absorb moisture).

 

Sealing is accomplished in two stages, a primary seal with butyl (to paste each piece of spacer rod) and a final one with tiokol (which is a sealed elastic polisulfid) that insulates perfectly the medium between the two panes of glass and has great time resistance.

 

Very important is the gas environment between the two glass sheets and, also, the distance between them, 16 mm is considered optimal for obtaining a good U-value.

 

Between the two panes of glass certainly there is no vacuum, that would break the glass windows (implosion) under external atmospheric pressure. Therefore, to obtain good results in terms of minimizing energy loss is inserting a rare gas such as argon or Krypton between the sheets of glass. Not all glass windows contain a rare gas, it depends on each manufacturer's equipment, technology used or desired performances.

 

Common types of insulating glass

 

Low-e + Clear, 24 mm

 

 

Low-e + Clear with argon gas, with a package thickness of 24 mm, is the ideal choice - optimal in terms of investment price relative to the further energy savings - when seeking very little heat loss from inside to outside.

 

Mounting the glass package in the joinery is done according to the figure, with the "soft" layer on face 3, with low-e glass on the inside.

 

In the table below we can track properties of this insulating glass, depending on the width of the glass, space between the sheets and gas used.

 

The U-value is very important and should be as small as possible if we desire a good thermal insulation.

Low-e + Clear, 24 mm

 

The solar contraol glazing, with a package thickness of 24 mm, preserves the qualities of low-e glass, but has a higher degree of protection against sunlight. It is the right choice when you wish to eliminate the greenhouse effect caused by natural solar energy. This can reduce conditioning costs in summer.

 

Mounting the glass package in the joinery is done according to the figure, with the magnetron layer on face 2, with the sheet of protective glass on the outside.

 

In the following table we can see the combination of glass properties depending on thickness, space between the glass panels and gas used.

 

The amount of light reflection is very important but also the U-value.

Clear + Clear, 24 mm

 

 

Clear + Clear glazing, with total thickness of 24 mm, is used as insulating glass when you do not need a superior isolation or thermal protection. For example, on the interior or in a house undemanding in terms of significant energy losses.

 

Assembly in the joinery system is standard.

 

This type of insulating glass is produced by the same process as other types of quality float glass, the difference being given by the smaller price but, also, by the package properties.

 

In the table below we can see the properties of this type of insulating glass.

U-values of glazings used

 

The "U" coefficient (U-value) for glazing, in accordance with EN 673, expresses the amount of energy (measured in Watts) that is lost through the surface of 1m2 every second, when the temperature is 20°C inside and -10°C outside.

 

The value differs from the "U" coefficient of the window (Uw) (which is calculated separately taking into account the U-values of the profiles used in the joinery), but shares the same result: the smaller, the better.
