The process of making the insulated glass units

An insulating glass unit is a glass panel consisting of at least two sheets of glass separated by a spacer, hermetically sealed to avoid heat loss by air circulation.

The space between the glass sheets can be filled with Argon, an inert gas, which improves the thermal performance of the panel.

The insulating glass can be mounted in any type of frame: aluminum, PVC, laminated wood, etc.

Performance indicators of a thermal insulation panel

1. Thermal Conductivity Uw (W/m2K)

It represents the amount of heat passed off by a insulated glass panel, with an area of ​​one square meter, during one hour, under the conditions of an external temperature of 0ºC, an internal temperature of 20ºC and a wind speed of 4.4 m/s

For an heat transfer efficient insulating glass, this indicator must be as low as possible.

2. Light Transmission TL (%)

It represents the amount of light allowed to pass through an insulating glass panel.

A high value of this indicator denotes a high-performance insulating glass that transmits more light.

3. Light Reflection R (%)

It represents the percentage of light reflected by the surface of the glass.

A high percentage of this indicator means more light is returning to the environment from which it came.

The glass can be treated to reflect both light from the visible spectrum, thus ensuring privacy, and also light from the infrared spectrum, thus ensuring the thermal comfort of the interior space.

For windows facing south, it is recommended that the insulating glass has a high light reflection in the infrared spectrum in order to reduce the heating of the interior spaces during the summer.

4. Sound insulation Rw (dB)

This indicator defines the insulated glass panel’s ability to reduce noise transmission.

An increased value denotes a superior sound insulation capacity of the panel, necessary to ensure sound
