DESCRIPTION
Johns Manville Attic Protector ® is premium blow-in fiber glass insulation that can be used to cover attics and hard-to-reach areas within attics, like corners, edges and around framing. When it’s applied in an air-sealed attic to the recommended thickness and specifications, you can be assured that your attic is energy efficient, with minimal heat loss. Attic Protector won’t appreciably settle, decay or provide food for animals or microbes. It’s effective for the life of your home.
USE
Attics – can be installed up to R-70 over ½" ceiling drywall without exceeding ceiling weight limits.
INSTALLATION
Attic Protector fiber glass makes it easy to insulate an attic of any size or shape without any cutting or fitting. It’s installed with a blowing machine and flexible hose, making it easy to insulate hard-to-reach areas in an attic. Large areas and small gaps can be filled quickly and completely.
PACKAGING
Attic Protector insulation is compression-packaged for savings in storage and freight costs.
DESIGN CONSIDERATIONS
Store insulation indoors. Keep insulation clean and dry at all times. When transporting, cover completely with a waterproof tarpaulin as necessary.
Refer to the JM guide specifications for further design considerations and required installation instructions.
LIMITATIONS OF USE
Check applicable building codes.
PERFORMANCE ADVANTAGES
Formaldehyde-Free: will not off-gas formaldehyde in the indoor environment.
Thermal Efficiency: provides effective resistance to heat transfer.
Sound Control: reduces transmission of sound through ceiling assemblies.
Fire Resistant and Noncombustible: see Specification Compliance.
Resilient Inorganic Glass: will not rot, mildew or deteriorate and is noncorrosive to pipes, wiring and metal studs.
Complete Coverage: effective in tight spaces, areas with large amounts of cross-bridging and areas with small gaps and voids.
