The difference between hollow glass and laminated glass.

Laminated glass and insulated glass are two common types of glass products currently available in the market.

Laminated glass and insulated glass are two common types of glass products in the market today, and they have some differences in structure, performance, and application.

Number of layers and materials

Laminated glass consists of interlayer materials between two layers of glass, while insulated glass has an air layer formed between two or more layers of glass through sealing.

The interlayer material in laminated glass is generally PVB (polyvinyl butyral), and there are other types of interlayer materials, such as EVA (ethylene-vinyl acetate copolymer).

The thickness of the air layer in insulated glass is generally between 12mm and 20mm, and it can also be filled with inert gases such as argon.

Sound insulation effect

Due to the presence of interlayer materials, laminated glass has better sound insulation properties.

The interlayer material can effectively block the propagation of sound waves, reducing noise transmission.

In contrast, the sound insulation effect of insulated glass is relatively poor, mainly reducing sound wave transmission through the air layer.

Thermal insulation performance

Laminated glass has better thermal insulation performance due to the addition of interlayer materials.

The interlayer material can effectively block the transfer of heat, reducing the impact of indoor-outdoor temperature differences on indoor temperature. Insulated glass, on the other hand, has relatively poor thermal insulation performance, as the air layer has high thermal conductivity, limiting its temperature isolation effect.

Safety

Laminated glass has a greater advantage in safety compared to insulated glass.

The interlayer material in laminated glass has strong adhesion, which can keep fragments attached to the interlayer material even when the glass breaks, reducing the risk of injury.

In contrast, when insulated glass breaks, the glass pieces can fall freely, posing a significant safety hazard.

UV resistance

Laminated glass performs excellently in UV resistance.

The interlayer material can effectively absorb and block UV radiation, protecting indoor furniture, flooring, and other items from UV damage.

In contrast, insulated glass has weaker UV resistance and lacks the shielding effect of interlayer materials.

Ease of maintenance

There are some differences in maintenance between laminated glass and insulated glass.

The interlayer material in laminated glass is easy to clean, but dirt on the glass surface requires professional cleaning agents for treatment.

Insulated glass, due to the presence of the internal air layer, is prone to gas infiltration, leading to condensation and fogging on the glass surface, requiring regular inspection and replacement.

Appearance effect

There are also differences in appearance between laminated glass and insulated glass.

Laminated glass can be specially treated to enhance its light transmittance and transparency, resulting in a clearer and brighter appearance.

In contrast, insulated glass may experience condensation and fogging on the glass surface in certain situations due to the air layer, affecting the clarity of its appearance.

Cost factors, application range, and environmental protection level

Laminated glass is generally more expensive than insulated glass and is mainly used in buildings with high requirements for sound insulation and safety.

Insulated glass, on the other hand, is relatively low in cost and suitable for the thermal insulation needs of general buildings.

From an environmental protection perspective, the interlayer materials in laminated glass are generally made from environmentally friendly materials, while insulated glass may have thermal bridge effects and atmospheric leakage due to the presence of sealed gaps, impacting the environment.
