Introduction
Curtain walls are widely used in modern architecture, especially in commercial buildings and high-rise structures. As a key part of the building envelope, curtain wall systems require materials that ensure safety, durability, and performance.
One of the most important decisions in curtain wall design is selecting the right type of glass.
Many project buyers and contractors often ask:
What glass is best for a curtain wall system?
This article provides a clear guide to help you choose the most suitable glass based on safety, performance, and project requirements.
What Is Curtain Wall Glass?
Curtain wall glass refers to the glass used in non-structural outer building facades. It does not carry the building load but must withstand:
Wind pressure
Temperature changes
Impact and safety risks
Therefore, curtain wall glass must meet higher standards compared to regular glass.
Common Types of Glass Used in Curtain Walls
1. Tempered Glass
Tempered glass is widely used due to its high strength and impact resistance.
Advantages:
High mechanical strength
Good thermal resistance
Cost-effective
Limitations:
Breaks into small pieces and may fall
Lower safety compared to laminated glass
2. Laminated Glass
Laminated glass is considered one of the safest options for curtain walls.
Advantages:
Holds together when broken
Prevents falling glass hazards
Provides sound insulation
Applications:
High-rise buildings
Areas with high safety requirements
3. Insulated Glass (Double Glazing)
Insulated glass consists of two or more glass panes separated by an air or gas layer.
Advantages:
Excellent thermal insulation
Energy efficiency
Reduces heat transfer
Applications:
Energy-saving buildings
Commercial curtain wall systems
4. Tempered Laminated Insulated Glass (Recommended)
In most modern curtain wall projects, a combination structure is used, such as:
Tempered + Laminated + Insulated glass
This type of glass provides:
High strength
Maximum safety
Energy efficiency
Noise reduction
It is widely considered the best solution for large-scale commercial buildings and high-rise curtain walls.
How to Choose the Best Glass for Curtain Walls
1. Safety Requirements
For high-rise or public buildings, laminated or tempered laminated glass is strongly recommended to prevent falling risks.
2. Energy Efficiency
If the project requires energy-saving performance, insulated glass (especially with Low-E coating) is a better choice.
3. Project Budget
Tempered glass offers lower cost
Laminated and insulated glass increase cost but improve performance
Choosing the right combination helps optimize total project cost.
4. Application Scenario
Different projects require different solutions:
Office buildings → Insulated laminated glass
Shopping malls → Laminated safety glass
Residential buildings → Tempered or insulated glass
