What Is A Glass Wool Sandwich Panel?
Glass wool is a fiber made from silicate minerals. The glass wool sandwich panel is composed of two layers of panels and a core layer of glass wool. It offers fire resistance, thermal insulation, and sound absorption, and is widely used in construction, industry, and other fields, meeting your requirements for large-scale installation.
Main Performance Characteristics of Glass Wool Sandwich Panels
Heat Insulation Performance
The glass fibers of glass wool are surrounded by numerous tiny pores, which cause the heat to be repeatedly reflected and conducted between the fibers. This effectively extends the heat transfer distance and results in a very low thermal conductivity. It can effectively prevent heat transfer.
Moreover, the large air volume in glass wool reduces the core board’s thermal conductivity, slowing heat transfer. This makes it suitable for an insulation material. When it is applied to equipment, it reduces energy consumption during operation.
Flame Resistance Property
Glass wool fibers are non-flammable materials. Their melting point is over 680℃, much lower than the temperature of a general fire. Compared with organic insulation materials, glass wool does not produce toxic gases and is classified as an A-level fire-resistant material.
If a ceramic coating is added to the surface of the glass wool sandwich panel, its fire resistance limit will increase by 30%. If your workshop has stringent fire safety requirements, the glass wool sandwich panel is a good choice.
Humidity Resistance
We achieve a 0.5% moisture content in Pupanel glass wool sandwich panels by controlling moisture during production. An anti-moisture layer is applied on the outer layer to achieve excellent moisture-proof performance and prevent bacterial growth. For glass wool fibers used in high-humidity environments, we recommend hydrophobic glass wool with an absorption rate of ≤3%.
Sound Isolation
For mid-to-high frequency sounds, its absorption coefficient is up to 0.99. To address the low absorption coefficient of glass wool for low-frequency sounds, we incorporate additional high-density materials into the sandwich panel to enhance low-frequency absorption.
This performance reduces machinery noise and reduces environmental noise pollution. It is well-suited for areas sensitive to noise, including industrial plants, warehouses, and residential areas.
Anti-Corrosion Resistance
The core component of glass wool fibers is silicon dioxide, and its chemical properties are stable. It resists corrosion from acids, alkalis, and salts and is suitable for various weather conditions. The corrosion resistance of glass wool varies depending on its sodium oxide content.
For example, non-alkaline glass wool with a sodium oxide content of less than 2% has the strongest stability and is suitable for coastal areas. However, high-alkaline glass wool with a sodium oxide content above 14.8% is unsuitable for use in the electrolysis and metal processing industries. Strong-acid electrolytes and acid wastewater will reduce the service life of high-alkaline glass wool.
Vibration Reducing Performance
The vibration-reducing performance of glass wool sandwich panels is attributed to their loose and porous structure. This structure absorbs vibration energy, ensuring the panels rebound stably.
The fibers inside the glass wool are closely interwoven and evenly arranged, and they can remain undamaged under long-term vibration. This ensures structural stability and performance for long-term use.
The vibration-reducing performance of glass wool sandwich panels makes them an ideal material for reducing vibrations in the construction and transportation industries.
Sustainability
The raw materials of glass wool sandwich panels are recyclable. The discarded glass wool is recycled and reused. Some glass wool sandwich panels use plant-based adhesives, reducing reliance on non-renewable resources such as petroleum.
The general lifespan of glass wool sandwich panels is 20 to 50 years. They have a long service life and less replacement frequency, which can reduce resource consumption.
