Does doubling insulation Double R-value?
Doubling the thickness of insulation will double the insulation’s R-value, cutting heat loss in half. Each time the insulation layer is doubled in thickness, this rule applies.
Is it worth replacing old insulation?
Fiberglass insulation typically needs to be replaced 15-20 years into it’s life, as it can easily become dirty, wet, moldy, and ineffective if there’s a roof leak or water damage of any kind.
