Spyder Fiber logo

At Harv Ginter Construction we use Johns Manville Spider® Plus fibre glass blow-in insulation. This insulation features interlocking fibre technology which is the next evolution of the JM formaldehyde-free™ insulation family. This technology allows the fibres to spring and lock into cavities with no adhesive or netting. This complete coverage results in superior thermal performance and sound control. With a simple installation that’s typically faster than other spray systems and unprecedented drying times.

Advantages of Spider® Plus

  • Improves Indoor Air Quality

    Formaldehyde free

  • Energy Efficient

    Provides superior resistance to head transfer with R-values up to R-24 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 fibreglass prevents settling

  • Controls Sound

    Reduces transmission of sound through exterior and interior walls and floor/ceiling assemblies

  • Easy to Install

    Insulates twice as fast as other spray-in systems

  • Mold and Mildew Resistant

    Fibreglass is naturally mold resistant

  • Fire Resistant and Noncombustible

  • Noncorrosive

    Does not accelerate corrosion of pipes, wiring or metal studs

  • Durable

    Will not rot, mildew or otherwise deteriorate. 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
