There are a number of reasons that you should have the old insulation removed from your roof cavity.
First and foremost, it will remove years, even decades, of toxic build-up of lead, insecticide and pollutants that settle in your roof cavity. Old types of insulation are very ineffective compared to today’s technology. Loose fill insulation in contact with heat sources and electrical fittings is a big fire hazard to your property. Air currents moving through the roof cavity cause loose fill insulation to shift causing hot and cold spots. Get rid of the major cause of dust in your home and reduce the allergens in your air.
If your insulation in your roof is more than 15 years old, there is a good chance that it is not doing a very good job. Old insulation was made to a very low standard with a low R value and blow in or loose fill insulation has a real chance of the chemical, Boron, leaching out with heat and condensation leaving you with shredded newspaper as your insulation. We’ll let you think about that one!
