When considering insulation, a commonly-used term is R-value. R-value measures how well the insulation can resist heat movement through it. However, R-value cannot measure heat movement carried in the air. Adding thicker insulation or higher R-value in your new home does not necessarily mean improved thermal comfort and air-sealing. In fact, you may still experience higher-thanaverage heating and cooling bills. Therefore, it’s important to consider how your new home’s insulation will perform over the long-term. An insulation and air barrier system such as Icynene spray foam insulation ensures that your home does not lose lots of heated or cooled air and provides an effective and building-code compliant R-value.
