Johns Manville’s Spider® Plus is a cavity spray fiberglass insulation with high performance at a competitive price point that is installed – and engineered to completely fill – open cavities such as walls before drywall installation.

JM Spider Plus is manufactured with interlocking fibers. When installed, these fibers spring and lock into place without adhesive or installing behind netting. This technology allows JM Spider Plus to completely fill any gaps and voids in a cavity with quick drying times. This gives your project high-energy performance and keeps your project moving ahead on schedule.

JM Spider Plus is a formaldehyde-free and a naturally mold-resistant clean fiber insulation. During installation it produces minimal dust, which means quicker job cleanup than other spray in systems.
