Rockwool and glass wool are two popular insulation materials, but they have distinct differences. Understanding these can help you choose the right material for your project.
What is Rockwool?
Rockwool, also known as mineral wool, is made from volcanic rock. It is denser and more rigid than glass wool, making it suitable for high-temperature applications.
What is Glass Wool?
Glass wool is made from recycled glass and sand. It is lighter and more flexible, making it easier to install in tight spaces.
Key Differences:
- Material Composition: Rockwool is made from basalt rock, while glass wool is made from recycled glass.
- Density and Strength: Rockwool is denser and stronger, ideal for heavy-duty applications. Glass wool is lighter and more flexible.
- Thermal Performance: Both materials offer excellent insulation, but glass wool has slightly better thermal efficiency.
- Fire Resistance: Rockwool can withstand higher temperatures (up to 1000°C), making it suitable for industrial use. Glass wool is fire-resistant but better for standard building insulation.
Best Uses:
- Rockwool: Industrial insulation, fireproofing, and soundproofing in high-noise environments.
- Glass Wool: Residential and commercial building insulation, HVAC systems, and general soundproofing.
Conclusion:
Both materials have unique advantages. Rockwool is better for high-temperature and heavy-duty applications, while glass wool is ideal for general insulation and soundproofing.
