Fiberglass Insulation Board | Fireproof Glass Wool Board for Wall and Ceiling
Jinsa glass wool board is an ideal choice for building energy-efficient, safe, and comfortable modern buildings due to its excellent insulation, sound absorption, fire resistance, and environmental performance. Choosing Jinsa mea
ns choosing a reliable professional guarantee and lasting value return.
Thanks to its comprehensive performance, Jinsa glass wool board has become the preferred material in multiple fields:
Indoor sound insulation and decoration: Used in internal partitions and suspended ceilings of offices, hotels, hospitals, schools and other places. While dividing spaces, it effectively isolates airborne sound and impact sound between rooms, improving privacy and comfort.
Industrial and equipment insulation: widely used for insulation of walls and roofs in steel structure factories and cold storage facilities; it is also a standardized material for thermal insulation and sound insulation in air conditioning and ventilation ducts, hot water pipes, equipment casings, etc.
Glass wool fibers are fine and interwoven, forming a complex three-dimensional structure containing a large number of pores filled with stagnant air. Air is an excellent thermal insulator, and these layers of stagnant air that are difficult to convect effectively block the conduction, convection, and radiation of heat, thus giving glass wool boards an extremely low thermal conductivity. Its thermal conductivity can usually be as low as 0.035-0.042 W/(m·K) (at room temperature), which means it can significantly slow down heat transfer. It is highly effective both in preventing indoor heat from escaping (thermal insulation in winter) and in blocking outdoor heat from invading (heat insulation in summer).
Glass wool board is a typical porous sound-absorbing material. When sound waves enter the interior of the material, they cause the vibration of air molecules in the gaps between the fibers. Due to friction and viscous resistance, sound energy is continuously converted into heat energy and consumed. This characteristic enables it to have a good absorption effect on medium and low frequency noises (such as traffic noise, equipment operation sound), which can effectively reduce the indoor reverberation time, improve speech clarity, and create a quiet office, living or entertainment environment.
