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.
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.
