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
