Insulating fireproof glass is a composite glass product composed of two or more pieces of glass, spacers, sealants, etc., with a closed air layer in the middle. This structural design makes hollow fireproof glass have good heat insulation and sound insulation performance, and can also improve the strength and stability of the glass to a certain extent.

The fireproof performance of hollow fireproof glass mainly comes from the fireproof layer, which is usually made of special fireproof materials. These fireproof materials can expand and foam at high temperatures to form a dense insulation layer to prevent the transfer of flames and heat.

The difference between single-sided and double-sided fireproof glass

• Single-sided insulating fireproof glass

- Single-sided insulated fire rated glass means that only one side of the glass has fireproof performance, and the other side is ordinary glass. This type of hollow fireproof glass is usually suitable for some places with relatively low fire protection requirements, or when the installation space is limited.

- The advantages of single-sided insulating fire resistant glass are relatively low cost and easy installation. At the same time, since only one side of the glass has fireproof performance, it is similar to ordinary hollow glass in appearance and will not have much impact on the overall beauty of the building.

- However, the fireproof performance of single-sided insulating fireproof glass is relatively weak, and it can only prevent the spread of fire to a certain extent. In the event of a fire, if the fire is large or lasts for a long time, the single-sided hollow fireproof glass may not be able to fully guarantee the safety of people and property.

• Double-sided insulating fireproof glass

- Double-sided insulating fireproof glass means that both sides of the glass have fireproof performance. This type of hollow fireproof glass is usually suitable for places with high fire protection requirements, such as high-rise buildings, large commercial centers, hospitals, schools, etc.

- The advantage of double-sided insulating fire resistant glass is that it has excellent fireproof performance and can effectively prevent the spread of fire when a fire occurs, buying precious time for personnel evacuation and fire rescue. At the same time, the heat insulation performance of double-sided insulated fireproof glass is also better, which can reduce the impact of fire on the surrounding environment.

- However, the cost of double-sided insulating fire rated glass is relatively high and the installation is also more complicated. In addition, since both sides of the glass have fireproof performance, the appearance may be different from ordinary hollow glass, which needs to be fully considered in the architectural design.

How to choose single-sided or double-sided hollow fireproof glass

1. Choose according to fire protection requirements

- If the building has high fire protection requirements, it is recommended to choose double-sided insulating fireproof glass to ensure better protection in the event of a fire. If the fire protection requirements are relatively low, you can consider choosing single-sided hollow fireproof glass to reduce costs.

2. Consider installation space and appearance requirements

- If the installation space is limited, or you want to maintain the overall beauty of the building, you can choose single-sided insulating fireproof glass. If the installation space is sufficient and the appearance requirements are not high, you can choose double-sided hollow fireproof glass.

3. Refer to professional opinions

- When choosing insualting fireproof glass, you can consult professional architects, fire engineers or glass suppliers, who can provide you with professional advice and selection options based on the specific situation.
