During a recent attic insulation project in Saint-Nazaire-D'acton, Québec, the homeowner who was still experiencing discomfort in his home despite having both fiberglass and cellulose insulation in the attic. Upon inspection, we explained that the amount of insulation present was still not sufficient to achieve the recommended thermal resistance of R60. Additionally, air leaks were still present beneath the existing layers, compromising the insulation’s effectiveness. To provide a permanent solution to this issue, we removed all existing insulation, thoroughly sealed every air leak, and then installed our high-performance TruSoft cellulose insulation in the adequate quantity to reach an R60 value, ensuring optimal comfort and energy efficiency.
