Window Chambers

A key component of any uPVC window is the glazing, which can account for anywhere from 25% to 95% of the total window surface, depending on size, design, and configuration. To meet individual customer preferences, modern windows can feature single, double, triple, or even quadruple-glazed units, each designed with specific, tested performance characteristics.

Glazing Chambers:

During the manufacturing process, glass panes are assembled at precisely defined distances from one another. The spaces between the panes are hermetically sealed and separated using edge seals to enhance insulation and prevent condensation.

Here are the most common types of insulated glass units used in uPVC windows:

• Single-chamber (Double-glazed): Consists of two panes of glass with one sealed air space.
• Double-chamber (Triple-glazed): Made of three panes separated by two sealed air spaces.
• Triple-chamber (Quadruple-glazed): Features four panes with three insulating air spaces.
• Four-chamber (Five panes): Includes five panes separated by four sealed chambers.

Insulated Glass Units (IGUs)

Every uPVC window is composed of the following core elements:

• Glazing (IGU)
• Sash and frame
• Hardware (locks, hinges, etc.)
• Seals and gaskets

These components work together to ensure thermal efficiency, sound insulation, durability, and security. The choice of chamber configuration should be based on the building’s insulation needs, climate conditions, and desired energy performance.
