Attic Insulation in Saint-Hyacinthe, QC
Challenge
During his inspection, our specialist observed that mold was widespread in several areas within the attic, a classic indicator of humidity and ventilation issues. Mold thrives in environments where warm, humid air accumulates without proper ventilation, often due to air leaks and inadequate insulation. In fact, the old insulation had lost its effectiveness, allowing thermal exchanges between the interior and exterior, thus reducing the energy efficiency. Additionally, multiple entry points for outdoor air, particularly around ventilation ducts, pipes, and wires, contributed to the accumulation of moisture.
Solution
The renovation of the attic began with the removal of the old insulation, allowing the mold-affected areas to be exposed and treated. Next, air leaks were sealed with ZypFoam to stabilize the indoor temperature and prevent moisture buildup. Finally, new TruSoft cellulose insulation was installed, providing fire-resistant, mold-resistant protection and ensuring high thermal efficiency with an R-value of 60.
