Rock Wool and Products FAQ
Q: What makes rock wool and products better than fiberglass insulation?
A: Rock wool and products offer superior fire resistance (Class A1 vs fiberglass's Class B), better sound absorption, higher temperature tolerance, and improved durability. Unlike fiberglass, rock wool maintains its shape and doesn't sag over time. The higher density of rock wool provides better thermal mass and acoustic performance in most applications.
Q: How should I handle rock wool and products during installation?
A: Always wear appropriate PPE including gloves, long sleeves, and a dust mask when handling rock wool and products. Cut materials with sharp tools on stable surfaces to minimize dust generation. Ensure proper ventilation during installation. For best performance, install without compression and seal all joints properly. Follow manufacturer guidelines for specific applications.
Q: Are rock wool and products environmentally friendly?
A: Yes, rock wool and products are made from abundant natural materials (basalt rock and recycled slag) and are themselves recyclable. The manufacturing process has become more energy-efficient in recent years. Additionally, the energy savings from proper insulation significantly offset the production footprint. Many of our rock wool products contain up to 75% recycled content and are certified by leading environmental standards.
Installation Guidelines
- Measure and mark the insulation area accurately
- Use appropriate cutting tools for clean edges
- Ensure tight fitting without excessive compression
- Seal joints with appropriate tape or adhesive
- Wear proper protective equipment during installation
- Follow local building codes and regulations
