Johns Manville (JM), a Berkshire Hathaway company and building products manufacturer, has added commercial and residential mineral wool to its full spectrum of insulation products, allowing customers to meet an even broader range of project demands.
JM mineral wool insulation offers a variety of performance benefits in both commercial and residential construction. With a high melting point in excess of 2000 F, mineral wool can help delay fire spread, create quieter buildings and homes, increase privacy between rooms and reduce heating and cooling costs by keeping structures warm in winter and cool in summer.
JM mineral wool is made from inorganic fibers using an advanced manufacturing process that ensures a high-fiber density and a low amount of shot material, resulting in consistent product quality and excellent performance.Dense and durable, the products can be easily and accurately cut and are available in a range of thicknesses and sizes. JM is the only manufacturer to offer compression packaging for mineral wool products for efficient storage and transport.
JM¹s line of mineral wool products include:
- TempControl Batts and Sound & Fire Block Batts are both lightweight, noncombustible and contribute to high fire-resistance ratings in wood-stud cavities. TempControl batts are available in R-15 and R-23 for exterior walls. Sound & Fire Block batts deliver excellent acoustical performance for interior walls. Ideal for residential applications, TempControl and Sound & Fire Block batts are also available in retail locations, including Lowe’s.
- MinWool Sound Attenuation Fire Batts (SAFB) are ideal for noise control in metal stud wall cavities of interior partitions, floor cavities and above suspended ceiling systems, improving wall assembly Sound Transmission Class (STC) ratings by up to an entire decibel level or 10dB.
- MinWool Safing insulation creates a fire-rated seal when installed between the spandrel panel and floor slab in commercial curtainwall systems, and prevents flame and smoke from passing through openings that penetrate fire rated assemblies.
- MinWool Curtainwall provides fire resistance and thermal properties in glass, metal and masonry curtainwall spandrel systems and can be placed between or over framing members.
The North American Insulation Manufacturers Association (NAIMA) touts mineral wool as essential to a high-performance insulation system that has been a proven choice for builders, architects and code officials. In fact, either mineral wool, fiber glass or both is found in more than 90 percent of U.S. homes.
According to NAIMA’s Insulation Institute website, “Mineral wool delivers a solution for every insulation and application need. It’s available in a comprehensive range of products and some of the highest thermal values possible, giving the right thermal performance and comfort for every environment.”
