Experts tell us that fibreglass and cellulose are dated insulation methods that have certain limitations. For instance, the large gaps and permeability of traditional insulation allows for significant heat loss in the winter and air conditioning loss during the summer. These products may have a cheaper up-front cost than spray foam, but in the long run, money is lost due to increasing energy bills as a result of air leakage. Additionally, traditional insulators have poorer sound barriers and are less effective against controlling airborne moisture.
Spray foam, either open or closed-cell, is now the leading insulation method. This innovation gives homes and buildings effective protection against air penetration, moisture build-up and sound penetration. The long-term benefits of spray foam trump fibreglass and cellulose. You can be assured that your energy bill will be reduced by as much as half when you replace a traditional insulation with spray foam.
