Composite Grouting Fire Rated Glass and Nano-silicone Fire Rated Glass

Composite grouting fire rated glass and Nano-silicone fire rated glass are two different types of heat-insulating fire-resistant glass. Their main difference:

Composite grouting fireproof glass is made by pouring fire-retardant liquid between two layers of glass. When the fire-retardant liquid is heated, it will expand into a white insulation layer to prevent the transfer of flames and heat.

Advantages of Composite grouting fireproof glass: high transparency, light transmittance of more than 80%, beautiful appearance, and less prone to defects such as bubbles.

Its disadvantage is that it is surrounded by black sealing tape and is not suitable for direct splicing, drilling, cutting, etc. The installation is limited to the four-sided inlay method.

In addition, grouting glass is not suitable for use on the west facing side of exterior windows and exterior curtain walls, because long-term ultraviolet rays will cause the color of the internal glue layer to become turbid, affecting the aesthetics.

Nano-silicone fire rated glass is made of inorganic transparent fire-proof glass and crystal silicon fire-proof glue. When the crystal silicon fire-proof glue is heated, it will harden into an opaque insulation layer to prevent the transfer of flame and heat.

The advantage of Nano-silicone fireproof glass is that it has good weather resistance, does not yellow, bubble or discolor, and can be used indoors and outdoors. Crystal silicon glass contains silica, which can improve the gloss of the coating film, has good fireproof and heat-insulating and transparent effects, and can also block most of the ultraviolet rays.

The disadvantages are that the price is higher, the production process is more complex, and raw materials need to be imported.

Due to the material used, Composite grouting fire resistant glass cannot be used outdoors where it is exposed to the sun for a long time. The fire retardant liquid will bubble, turn yellow and even leak when exposed to high temperature ultraviolet rays, affecting the appearance and certain fire resistance. This is a defect of composite grouting fire resistant glass.

If you need to use fire-resistant glass, it is recommended that you choose other types of composite fire-resistant glass, such as Nano-silicone silicon fire-resistant glass, which has good weather resistance, does not yellow, bubble or discolor, and can be used indoors and outdoors.
