Laminated Glass Panels

Laminated glass panels (Triplex glass) are manufactured by bonding two or more panes – glass sheets, together with PVB interlayers under conditions of increased heat and pressure, to create a single sheet of glass. That is, Triplex glass refers to the bonding of 2 or more panes (e.g., bonding two 5 mm panes, which we call 5+5 Triplex).

In case of glass breakage, the interposed PVB interlayer keeps the sheets connected and prevents the glass from shattering, creating a “spider web” effect. The interposed interlayer also increases the sound insulation capacity of the glass panels.

There are dozens of PVB interlayers with different properties. The PVB interlayers used can be sound-absorbing, thus creating sound-insulating glass panels (see more about interlayers in sound-insulating glass), or they can be interlayers with increased safety and impact resistance or greater shading and privacy.

Laminated glass panels are available in various thicknesses and a huge variety of colors.

What do 5+5 or 4+4 Triplex glass panels mean?

Triplex glass panes have code names depending on the thickness of the panes that are joined. That is, when we have 5+5 Triplex glass, it means that 2 panes of 5 mm are joined, while when we have 4+4 Triplex, 2 panes of 4 mm are joined.

In the case of double energy-efficient glass and when you hear that you have been offered 5 / 16 / 4+4 Triplex energy-efficient glass panels, this means that you will receive glass with a cross-section of 5 mm / with a 16 mm gap / and two bonded 4 mm Triplex glass panels.
