Aluminum silicate fiber paper has many important functions in building insulation, mainly in heat insulation, fire prevention, sound insulation and so on. The following are its specific applications and functions:

I. Thermal insulation

Reduce heat transfer: Aluminum silicate fiber paper has very low thermal conductivity (usually between 0.03 and 0.17 W/m k), which can effectively prevent heat transfer from high temperature area to low temperature area. In building thermal insulation, it can significantly reduce indoor and outdoor heat exchange, reduce indoor heat loss in winter and increase indoor heat in summer.

Improve energy efficiency: By reducing heat loss, aluminum silicate fiber paper can reduce the energy consumption of buildings and improve energy efficiency. This will not only help to save energy and reduce emissions, but also reduce the cost of heating and cooling.

II. Fire performance

High temperature resistance: aluminum silicate fiber paper can withstand high temperature up to 1300℃ and has excellent fire resistance. When a fire breaks out, it can effectively stop the spread of the fire and prolong the fire-resistant time of the building structure.

Fire prevention and heat insulation: aluminum silicate fiber paper can be used as heat insulation material for fire doors, firewalls, cable bridges and other parts to improve the fire prevention performance of buildings. For example, it can be used for thermal insulation cotton strips of fire doors to prevent the fire from spreading through the crack of the door.

III. Sound insulation and noise reduction

Sound insulation effect: aluminum silicate fiber paper has certain sound insulation performance, which can effectively reduce the interference of external noise to the room. In buildings, it can be used as the sound insulation layer of walls, roofs and floors to improve the sound insulation effect of buildings.

Improve the indoor environment: By reducing the transmission of noise, aluminum silicate fiber paper can provide a quieter and more comfortable living and working environment for the interior of the building.

IV. Chemical stability

Corrosion resistance: aluminum silicate fiber paper has good chemical stability and can resist the corrosion of many chemicals. In the building environment, it is not easily affected by environmental factors such as humidity, acid and alkali, and has a long service life.

Environmental protection and pollution-free: aluminum silicate fiber paper contains no harmful substances such as asbestos, which is harmless to human body and environment and meets the requirements of modern buildings for environmental protection materials.

V. Construction convenience

Good flexibility: aluminum silicate fiber paper has good flexibility and machinability, can be easily cut, folded and installed, and adapts to various complex building surfaces.

Fast installation: the construction process is simple and fast, which can shorten the construction time and reduce the impact on the use of buildings.

VI. Application examples

Roof insulation: In building roofs, aluminum silicate fiber paper can be used as a thermal insulation layer to reduce the transfer of solar radiation heat in summer and reduce the indoor temperature.

Wall insulation: used in external wall insulation system, it can effectively reduce the exchange of indoor and outdoor heat and improve the thermal insulation performance of buildings.

Floor insulation: laying aluminum silicate fiber paper under the floor can reduce heat loss from the ground and improve indoor comfort.

Fire doors and firewalls: As thermal insulation materials of fire doors and firewalls, it can improve the fire performance of buildings and extend the time for evacuation and fire rescue in case of fire.

VII. Summary

Aluminum silicate fiber paper has many important functions in building insulation, such as heat insulation, fire prevention, sound insulation and corrosion resistance. It can not only improve the thermal insulation performance of buildings, reduce energy consumption, but also significantly improve the safety and comfort of buildings. With its excellent performance and construction convenience, aluminum silicate fiber paper has become one of the ideal materials for modern building insulation.
