Why Choose Mineral Wool? Mineral wool is a fibrous insulation material, similar in appearance to fiberglass but made from natural or recycled materials like rock or slag. It traps air, creating a thermal barrier that keeps your home warm in the winter and cool in the summer. Mineral wool also boasts excellent fire resistance, providing an extra layer of safety for your home. By trapping air, mineral wool insulation helps regulate home temperature, lowering your energy bills. Best Mineral Wool Applications:

• Walls & Ceilings: Fills cavities in stud walls and provides superior soundproofing between floors for a quieter living environment.
  
  
• Attics: Provides superior thermal insulation for attics, keeping your home cooler in the summer and warmer in the winter.
  
  
• Floors: Reduces heat loss through floors, especially above crawl spaces or basements, for improved comfort throughout your home.
  
  
• HVAC Systems: Insulates pipes and ducts to minimize heat gain or loss, ensuring your HVAC system operates at peak efficiency.
  
  

What is mineral wool insulation made of? There are two main types:

• Rockwool: Made from spun fibers of molten basalt or similar volcanic rock.
  
  
• Slag wool: Made from recycled industrial byproducts like iron ore slag.
  

Does mineral wool insulation need a vapor barrier? In most cases, yes. A vapor barrier helps prevent moisture from entering the insulation, which can reduce its effectiveness and lead to mold growth. Check with your local building codes for specific requirements.
