How to Install

How to Install : Step Four

GreenFiber Insulation installs easily over any existing insulation, filling gaps and voids. 

To achieve the desired R-value it is important to install the correct thickness of GreenFiber Insulation. 

Be sure to keep GreenFiber Insulation from filling soffits. Use a soffit vent baffle as shown below.

Install

  • Put on safety eyewear and NIOSH-approved dust mask (N95)
  • Turn on the blowing machine. The product will begin to flow through the hose. Adjust the product slide gate to wide open or the air setting as needed.
  • Begin to insulate at the corner farthest from the attic access and work back. Be careful to step on top of and not between the ceiling joists.
  • Hold the hose approximately 3 feet above the installation surface and distribute the insulation evenly.
  • Do not block soffits or cover heat sources with insulation unless they are type IC rated for contact with insulation.
  • Fill to the desired depth, using attic markings and rulers as guides.
  • Use all the bags required to achieve your desired R-value.
  • Empty the blowing machine when you are finished and clean up the surrounding area.
  • Return machine to the same retail location you rented it from.

Tips

Do not fill soffits with insulation. Use soffit vent baffles to allow the soffit to stay open above the insulation for proper air flow. Insulate the inside of the access hole cover with batt or foam board insulation to complete the job.

CAUTION:

To help avoid fire: Keep insulation at least three inches away from the sides of recessed light fixtures. Do not place insulation over such fixtures so as to trap heat unless they are type IC rated for contact with insulation. Also keep insulation away from exhaust flues of furnaces, water heaters, space heaters or other heat-producing devices. To be sure that insulation is kept away from light fixtures and flues, use a barrier to permanently maintain clearance around these areas. Check with local building or fire officials for guidance on installation and barrier requirements. (US Federal Regulation 16 CFR Part 1404.4).
