JM Spider® Plus blow-in insulation, now featuring interlocking fiber technology, is the next evolution of the JM insulation family.
Interlocking fiber technology allows the fibers to spring and lock into cavities to fill all gaps and voids with no adhesive or netting. And with a simple installation that is typically faster than other spray systems and unprecedented drying times, Spider Plus saves professional installers time and money on every project.
With up to 30% better air resistance than competitive products, Spider Plus achieves R-15 in 2x4 and R-23 in 2x6 walls and a Sound Transmission Class (STC) rating of 43 in a standard 2x4 wood-framed wall to achieve Grade 1 installation.
The Formaldehyde-free™ and naturally mold-resistant clean-fiber insulation produces minimal dust during installation and features a quicker jobsite cleanup compared to other spray-in systems.
Spider Plus works well in all types of building cavities, filling interior and exterior walls, floors and cathedral ceilings more completely with no shrinking or settling. Simply spray and shave for a full, quick cavity fill. And it uses minimal water to install quickly, and dries fast for same-day drywall installation — saving time and money.
