1. Tinted Glass Pane
The tinted glass pane absorbs part of the incoming solar radiation, helping reduce glare and solar heat gain. Common colour options include grey, bronze, green, and blue, subject to glass type, thickness, and availability.
UV transmission varies according to the tint colour, glass thickness, coating, and complete glazing configuration. Where verified UV performance is required, use the corresponding product test data. Heat treatment may also be required after evaluating panel size, solar exposure, edge condition, and thermal-stress risk.
2. Insulating Cavity
Tinted insulated glass consists of two or more panes separated by a spacer and sealed to create an insulating cavity. The cavity may contain dry air or an inert gas such as argon or krypton, depending on the required specification.
Cavity width, gas type, glass composition, spacer system, and Low-E coating all influence the thermal performance of the finished IGU.
3. Edge-Sealing System
The spacer, desiccant, primary seal, and secondary seal work together to limit gas leakage and moisture penetration. A correctly manufactured edge system helps maintain a dry cavity and reduce the risk of condensation forming between the panes.
Long-term performance depends on sealant compatibility, production control, installation quality, drainage, and environmental exposure.
4. Thermal and Solar-Control Performance
The insulating cavity helps reduce heat transfer, while the tinted pane can reduce solar heat gain. U-value and Solar Heat Gain Coefficient (SHGC) are determined by the complete glass configuration rather than the tint alone.
For projects with specific energy-performance targets, the selected IGU should be evaluated using configuration-specific U-value, SHGC, and visible light transmittance data.
5. Acoustic Performance
Multiple glass panes and a sealed cavity can improve sound insulation compared with a single pane of similar glass. Acoustic performance depends on pane thickness, asymmetric glass construction, cavity width, laminated interlayers, framing, seals, and installation.
Where a specific STC or Rw rating is required, select a complete tested glazing configuration.
