Potential Symptoms

  • Irritation of eyes, skin, mucous membranes; 
  • blocked nose, dry nose, sneezing; 
  • hoarseness, cough and phlegm; 
  • exercise-induced dyspnea

Safety and health checklist

  • If there is existing insulation that is deteriorated, wet or moldy, it should be removed. 
  • If there is already blown-in insulation in place, cellulose can be blown over the top. 
  • In attics with fiberglass batts, the batts should either be removed, or the cellulose blown under the batts to make contact with the ceiling below. 
  • For best performance, the cellulose should cover any existing insulation and framing.
