Attic Insulation in Vaudreuil-Dorion, Quebec

A homeowner contacted us regarding issues with cold air infiltration and elevated energy consumption, which indicated a deficiency in the attic’s thermal insulation. Upon thorough inspection, we identified the existing insulation as inadequate, and further detected mold growth on the wooden rafters and underneath the insulation layer, attributed to insufficient ventilation and moisture entrapment.

To address these deficiencies, we commenced by removing the compromised insulation to expose the full extent of air leakage points. We applied Mold-X2, a specialized mold treatment, to completely eradicate the spores from the wooden structure. Subsequently, we used ZypFoam to precisely seal all air leaks, effectively preventing future energy loss and air drafts. Finally, we installed 17 inches of TruSoft cellulose insulation, achieving a thermal resistance value of R60. This upgrade significantly enhanced the attic’s energy efficiency, providing improved thermal regulation and moisture protection. The homeowner expressed satisfaction with the resulting increase in home comfort and the anticipated reduction in energy expenses.
