USE:
JM Sound & Fire Block batts are designed to deliver noise control in wood-stud cavities of interior walls and ceilings between floors.

INSTALLATION:
In standard wood framing, carefully insert batts between the wood studs or joists to fill the cavities with a friction-fit to framing members. JM mineral wool batts are easily cut with a knife for quick installation and snug fit in nonstandard size cavities.                                    Suspended Ceilings: When approved by the ceiling system manufacturer, lay JM mineral wool batts over the ceiling area so that the insulating material is supported by the ceiling suspension system, not the ceiling panels themselves.

PACKAGING:
JM mineral wool products are compression packed for more efficient storage and transport.

PERFORMANCE ADVANTAGES:
Excellent Acoustical Performance: Lightweight, flexible insulation batts are excellent sound absorbers, efficiently reducing sound transmission. JM wool batts improve the Sound Transmission Class (STC) ratings of interior partition walls and suspended ceilings. The high-density, non-combustible fiber in mineral wool reduces unwanted noise from traveling from room to room, making
homes quieter.

Fire Safety: Mineral wool Sound & Fire Block has a melting point in excess of 2000°F (1093°C). See Applicable Standards for details.

Noncombustible: See Applicable Standards for details.

Durable & Inorganic: JM wool batts do not support growth of fungi, nor do they sustain vermin.
