Spider® Plus Blow-In Custom Fiberglass Insulation

Johns Manville Spider® Plus Formaldehyde-Free™ blow-in fiberglass insulation uses interlocking fiber technology to fill all gaps and voids quickly with no adhesive or netting for a faster installation. Spider Plus provides complete coverage, with no shrinking or settling, resulting in superior thermal performance and sound control. Designed for use in wood- and metal-frame construction, engineered-wood construction and manufactured homes.

FEATURES:

• Fast Drying - Dries immediately once installed.
• Complete Coverage - Effective in tight spaces, areas with large amounts of cross-bridging or small gaps and voids.
• Thermally Efficient - Effective resistance to heat transfer, with R-values up to R-25 in a 6'' cavity.
• Formaldehyde-Free - Will not off-gas formaldehyde in the indoor environment.
• Sound Control - Reduces sound transmission through exterior and interior walls, floor and ceiling assemblies.
• Fire-Resistant - Flame Spread of 25 or less and Smoke Developed of 50 or less.
• Resilient Inorganic Glass - No rotting, mildew or deterioration. Also noncorrosive to pipes, wiring and metal studs.

APPLICATIONS:

• Thermal and Acoustical Insulation of Interior and Exterior Walls and Ceiling/Floor
• Assemblies (with stud or joist cavities).
• Wood-frame construction – residential homes and light commercial buildings
• Metal-frame construction – residential and commercial buildings
• Manufactured homes – modular or manufactured housing
• Engineered-wood construction – assemblies framed with 12" to 19.2" on-center cavities.

PERFORMANCE ADVANTAGES:

• Improves indoor air quality: because it’s made without formaldehyde.
• Energy efficient: provides superior resistance to heat transfer with R-values up to R-23 in a 2x6 cavity.
• Covers completely: gap-free coverage maximizes thermal and acoustical performance and minimizes air leakage where energy can escape.
• Resilient: interlocking lightweight fiberglass prevents settling.
• Controls sound: reduces transmission of sound through exterior and interior walls and floor/ceiling assemblies.
• Easy to install: insulates a typical 2,700 sq. ft. home in 2–3 hours, twice as fast as other spray-in systems.
• Mold and mildew resistant: fiberglass is naturally mold resistant.
• Fire resistant and noncombustible: see Test Data.
• Noncorrosive: does not accelerate corrosion of pipes, wiring or metal studs.
• Durable: will not rot, mildew or otherwise deteriorate. JM Spider Plus insulation will not hold moisture or permanently lose R-value.
• Fast drying: requires less moisture than other spray-in systems during installation and dries immediately when installed as recommended.
