Glass curtain walls usually require the following main materials:

1. Glass type:

Tempered glass: has high strength and impact resistance.

Laminated glass: consists of multiple layers of glass and interlayer materials in the middle, with high safety, and the fragments will not splash when broken.

Insulating glass: consists of two or more pieces of glass with dry gas in the middle, with good heat insulation and sound insulation.

Coated glass: such as low-emissivity coated glass, can effectively control indoor and outdoor heat exchange and improve energy saving.

2. Metal frame material:

Aluminum alloy: light weight, corrosion resistance, good processing performance.

Stainless steel: high strength and strong corrosion resistance.

3. Sealing material:

Silicone sealant: has excellent weather resistance and bonding performance.

Rubber sealing strip: used to seal the gap between glass and frame.

4. Connectors and anchors:

Stainless steel bolts, screws, etc.: used to connect the frame and the main structure.

5. Fireproof materials:

Fireproof rock wool: has good fireproof and heat insulation properties.

Fireproof sealant: can effectively prevent the spread of fire in case of fire.

6. Structural adhesive: used to bond glass and metal frames to withstand external forces such as wind loads.

7. Filling materials:

Thermal insulation materials, such as polystyrene foam boards, etc., to improve the thermal insulation performance of curtain walls.

8. Hardware accessories:

Hinges and handles for opening windows.

For example, in the glass curtain wall of a high-rise commercial building, tempered hollow glass may be used as the main panel material, aluminum alloy frames as supporting structures, silicone sealants for sealing, stainless steel connectors to ensure structural stability, and fireproof rock wool for fire partitions.
