Fiberglass Insulation
Introduction
The fiberglass insulation takes quartz sand and borax as main raw materials. By1400℃ high temperature melting, we get the molten glass. Then with the most advanced centrifuge technology, we fiberize the molten glass and add a certain amount of adhesive into it. Finally, the fiberglass insulation blanket will be finished by the curing process.
The fiberglass batt insulation is the first choice to limit temperature changes and sound transmission inside steel framed buildings. The air is the carrier of sound and heat. Inside our product, there are quantities of super fine fiberglass. The total surface area is also very large, so as to enhance the resistance to the air, making it impossible to flow, and eliminate the convective heat transfer. The enormous friction also results in the fast attenuation of air vibration. The attenuation will endow the fiberglass insulation with excellent sound absorption and heat insulation effect.
Features
1. Whether under conditions of high temperature or low temperature, the fiberglass keeps good thermal insulation properties.
2. The product is fire-retardant, and does not produce harmful gases. It is identified as the legal non-combustible material worldwide.
3. A consistent elastic restoring force.
4. Good absorption of low, medium, and high frequency sound. Good noise reduction effect.
5. Small moisture absorption rate under wet conditions.
6. Small linear expansion coefficient.
7. Low aging rate. After long-term use, the fiberglass insulation still maintains the original performance.
8. Good processing properties.
Heat Insulation Performance Comparison with Other Insulation Materials
The following data show the thickness comparison between the 12 kg/m3, 50 mm thick fiberglass with other materials with the same insulating effect.
