Sound Insulation Performance of Fireproof Glass

Glass is an indispensable product in our daily life. It is used almost everywhere, such as doors, windows, cabinets, decorations, etc. Fireproof glass is a common type in the world now, and it has very unique functional characteristics.

Fireproof glass is composed of two or more layers of flat glass. High-strength and high-airtightness composite adhesive is used around to bond and seal two or more pieces of glass with sealing strips and glass strips. Dry gas is filled in the center and desiccant is filled in the frame to ensure the dryness of the air between the glass sheets.

Optical properties depending on the glass material used, insulating glass can have various optical properties. Its visible light transmittance ranges from 10% to 80%; light reflectance ranges from 25% to 80%; total transmittance ranges from 25% to 50%. Insulation properties Insulating glass has excellent insulation properties. Under certain conditions, its insulation properties can be better than concrete walls.

Fireproof glass has good sound insulation function, which is generally related to the type and intensity of noise. It can generally reduce noise, that is, it can reduce the noise of street cars to the quiet level required by school classrooms. When the temperature is too low, condensation will inevitably occur, which will seriously affect the perspective and lighting of the glass and cause some other adverse effects.

Radiation transfer is the transfer of energy through radiation, which includes visible light, infrared and ultraviolet radiation, just like the transfer of sunlight. Reasonable configuration of glass and reasonable thickness of insulating glass and laminated glass spacer can reduce the transfer of energy through radiation, thereby reducing energy loss.
