Thin triple-pane insulated glass units deliver high-performance glass in a thinner, more efficient manner.

These units have a much better U-value than traditional double glazing, while also solving thickness and weight issues.

Thin triple-glazed insulating glass is particularly suitable for new build and refurbishment residential applications. For new construction, its reduced weight simplifies transportation and installation. And it can eliminate functional issues, such as opening and closing force issues on heavy-duty sliding windows.

Perhaps the most significant difference between the thin three-layer IGU and its traditional counterpart is thickness. A traditional three-layer IGU is usually 4-5mm thick glass outer panels and 3-4mm thick middle panel. In contrast, thin units use very thin 0.5 mm glass as the middle panel. (The thickness of the single-layer TPS spacer also decreases). The reduction in thickness makes the glass overall lighter, thinner and more compact.

The thickness of 0.5mm or 0.7mm of Our CHIYAN ultra-thin alumino-silicate glass can be used as middle panels.

Key differences between thin triple-layer IGU and other insulating glass types

IGUs have undergone significant changes since their first use. In the 1980s, double glazed units were typically around 20mm thick. By the 2000s, Low-E three-layer IGUs were available, with a thickness of approximately 36 mm. These three-layer IGUs provide enhanced insulation but are also 50% thicker and heavier.

The thin triple layer IGU has a total thickness of only 24.5mm and still maintains the same high performance as the traditional triple layer IGU.
