Insulating Glass
Double insulating glass is obtained by sealing the two panes of glass separated by an aluminum rod spacer of different thicknesses, which has small perforations to the inside where it was first introduced in silica (a silicate amorphous form of granules small that acts like a sponge absorbing moisture from a large capacity).
Sealing is accomplished in two stages, a primary seal with butyl (to paste each piece of glass rod spacer) and an end tiokol (which is a sealed elastic polisulfid) that insulates the perfect medium between the two panes of glass and has to withstand high time.
Very important is the environment of gas between two glass sheets and also the distance between them 16 mm is considered optimal for obtaining a good "Uw" value.
Between the two panes of glass certainly is no vacuum , that would break the glass windows (the implosion) under atmospheric pressure outside. Therefore to obtain good results in terms of minimizing energy loss is inserted between sheets of glass a rare gas such as argon or Krypton.
Not all glass windows contain a rare gas, it working considering the equipment of each manufacturer, the technology used, or the performances followed.
Common types of insulating glass
Low-e + Clear, 24 mm
Low-e glazing + Clean argon gas, with a thickness of 24 mm package, is the ideal choice - optimal in terms of price relative to the economy further investment of energy - when seeking a loss as little heat from inside to outside.
Package in the joinery assembly is enclosed under the cover figure "soft" on the front 3, so low-e glass on the inside.
In the table below can track properties of this insulating glass depending on width of the glass used, space between the sheets and the gas used:
Very important is the value "U" which should be as small as if watching a good thermal.
| Glazing low-e | Coating on surface | Light Trans- mission [%] |
Light Reflection [%] |
Colour rendering index Ra |
Solar factor EN 410 [%] |
Value U EN 673 (15K) [W/(m2K)] |
|---|---|---|---|---|---|---|
| 4-16-4 (Argon) | 3 | 80 | 12 | 98 | 66 | 1,2 |
| 4-16-4 (Air) | 3 | 80 | 12 | 98 | 66 | 1,4 |
Glazing: Solar4S + Clear, 24 mm
(similar:4Seasons,SunGuard,DualProtect)
Glazing with solar control, with a thickness of 24 mm package, preserve the qualities of type low-e glass, but has a higher degree of protection against sunlight outside to inside. Is the right choice when you wish to eliminate greenhouse flats by reason of their natural energy from the sun. This can reduce cooling costs in summer.
Package in the joinery assembly is enclosed with cover according to figure magnetron soft face 2, so the sheet of protective glass on the outside.
The following table can follow the combination of glass properties depending on thickness, space between the glass panels and gas used:
Very important is the amount of light reflection but also the value of coefficient "U".
| Glazing Solar4S | Coating on surface | Light Trans- mission [%] |
Light Reflection [%] |
Colour rendering index Ra |
Solar factor EN 410 [%] |
Value U EN 673 (15K) [W/(m2K)] |
|---|---|---|---|---|---|---|
| 4-16-4 (Argon) | 2 | 66.9 | 26.6 | 96.1 | 42.5 | 1,1 |
| 4-16-4 (Air) | 2 | 66.9 | 26.6 | 96.1 | 42.5 | 1,3 |
Glazing: Clear + Clear, 24 mm
Glazing Clear + Clear, with total thickness 24 mm, is used as insulating glass when you do not follow an isolation or a superior thermal protection. For example the interior or house without demanding in terms of significant energy losses.
Assembly in the carpentry package is standard.
Achieving this type of insulating glass is made by the same process with other types of quality float glass, the difference being given by the price (less the acquisition) but also the package properties.
In the table below may follow this type of insulating glass properties:
| Glazing Solar4S | Coating on surface | Light Trans- mission [%] |
Light Reflection [%] |
Colour rendering index Ra |
Solar factor EN 410 [%] |
Value U EN 673 (15K) [W/(m2K)] |
|---|---|---|---|---|---|---|
| 4-16-4 (Air) | NA | 82.8 | 15.3 | 98.5 | 79.5 | 2,7 |
Values 'U' of glazing used
The coefficient "U" in accordance with EN 673 if glazing express the amount of energy (measured in Watt unit) that is lost through the surface of 1m 2 every second, in conditions where the inside are outside the 20 °C and -10 °C.
The different value of coefficient "U" all the window (which is calculated separately taking into account the profiles carpentry and k values used), but the more small the better.
| Glazing 24 mm | Configuration | Value U EN 673 (15K) [W/(m2K)] |
|---|---|---|
| Low-e + Clear + Argon | 4-16-4 (Argon) | 1,2 |
| Low-e + Clear | 4-16-4 (Air) | 1,4 |

| Solar 4S + Clear | 4-16-4 (Argon) | 1,1 |
| 4Seasons + Clear | 4-16-4 (Argon) | 1,1 |
| Smoked + Low-e | 4-16-4 (Air) | 1,4 |
| Krizet (Mat) + Clear | 4-16-4 (Air) | 2,7 | Ornament (any model) + Clear | 4-16-4 (Air) | 2,7 | Ornament (any model) + Low-e | 4-16-4 (Argon) | 1,2 | Reflexiv Bronze + Low-e | 4-16-4 (Argon) | 1,2 |
