Installation: Loose-Fill Insulation

Although you can rent a blowing machine from lumberyards and install loose-fill insulation yourself, CertainTeed recommends that you hire qualified professionals.

In an attic, installation of blown-in insulation includes these steps:
  • Run a hose from the blowing machine through any available attic opening.
  • Blow insulation in the direction of the joists, keeping the hose close to the floor.
  • To achieve the desired R-value, the insulation must be installed to the manufacturer’s recommended minimal thickness using the recommended number of bags.
