Mineral Wool Insulation: What You Need to Know

Mineral wool insulation, also known as stone wool or rock wool, is a high-performance material used for thermal, acoustic, and fire-resistant applications. Manufactured from natural stone and recycled materials, it offers exceptional durability, energy efficiency, and versatility for residential, commercial, and industrial projects. Mineral wool insulation is an ideal choice for improving building performance while maintaining safety and comfort.

Key Features:

  • Superior Thermal Resistance: Mineral wool provides high R-values, maintaining indoor comfort by reducing heat transfer. Its dense structure traps air effectively, making it a reliable option for year-round energy savings.
  • Exceptional Fire Resistance: Non-combustible and capable of withstanding temperatures up to 1,800°F, mineral wool acts as a critical barrier in fire-sensitive areas, offering enhanced safety for residential and commercial buildings.
  • Acoustic Performance: The dense fibers of mineral wool absorb sound, reducing noise transfer between rooms or floors. This makes it particularly effective for multi-family homes, office buildings, and other noise-sensitive environments.
  • Moisture Resistance: Naturally hydrophobic, mineral wool repels water while allowing vapor to pass through. This feature helps prevent mold and mildew growth, ensuring long-lasting performance in damp or humid spaces.

Batt Insulation:

  • Pre-Cut Batts: Mineral wool batt insulation is pre-cut to fit standard wall and ceiling framing, simplifying installation and minimizing waste. These semi-rigid batts maintain their shape and stay in place without sagging, ensuring consistent performance over time. Batt insulation is ideal for DIY projects or professional installations in areas like soundproof walls, ceilings, and attics.
  • Batt Construction: Mineral wool batts are semi-rigid, maintaining their shape during installation and ensuring consistent insulation performance over time.
  • Sizes: Mineral wool insulation is available in pre-cut batts, designed to fit standard framing dimensions for walls and ceilings. Dimensions such as 15-1/4 inches x 47 inches or 15.25 inches x 47 inches, covering approximately 59.7 square feet per package.

R-Values:

  • R-13: Ideal for walls and floors in moderate climates, R-13 insulation provides effective thermal resistance without adding bulk. It’s a practical choice for interior walls, crawl spaces, and retrofits where space is limited.
  • R-15: Offering higher thermal resistance, R-15 is perfect for colder climates or areas needing enhanced energy efficiency. It performs exceptionally well in exterior walls, reducing heat loss while also providing added acoustic and fire-resistant benefits.

Applications:

  • Exterior Walls and Facades: Provides a thermal and acoustic barrier, reducing heat loss and sound transfer in building envelopes.
  • Roofs and Attics: Improves insulation in both flat and sloped roofing systems, ensuring consistent temperatures and energy savings.
  • Interior Partitions: Enhances acoustic privacy in homes, hotels, and offices by reducing sound transmission through walls.
  • Industrial Use: Used in high-temperature environments, such as industrial furnaces and pipelines, where fire and heat resistance are essential.

FAQ

 Do you offer same-day mineral wool delivery in Los Angeles?

Often yes. Place early orders for same-day delivery to areas like Glendale, Pasadena, and the South Bay. For bulk multifamily drops, book a scheduled window so material lands just-in-time floor by floor. This limits on-site storage and keeps trades moving without waiting on trucks.

Why is mineral wool common in Los Angeles multifamily and hillside projects?

It pairs strong acoustics with excellent fire resistance, useful for demising walls near transit corridors and for homes near wildland-urban interfaces. The batts friction-fit into stud bays, speed up installs, and tolerate higher temperatures, helping builders meet assembly requirements without specialty applicators.

Can mineral wool be carried inside during interior buildouts?

Yes. White Gloves bring batts through the first doorway to a ground-level room, ideal for occupied remodels or narrow sites. If your crew will handle the move-in, Curbside places the pallets within five feet of the truck at street or driveway level.

Are there minimum order requirements for mineral wool delivery in Los Angeles?

No strict minimums apply for most orders. Smaller residential projects in places like Highland Park or Santa Monica can be fulfilled with just a few bundles. For larger multifamily developments, pallet orders are common and allow for more efficient truck routing and unloading. Scheduling these bulk drops ensures crews receive continuous material flow without delays.
