Ventilation challenge when insulating with spray foam

It is never easy to achieve a perfect balance when you decide to use spray foam as your chosen insulation method. While it makes your HVAC unit function more efficiently and with less energy consumption, it can be stressful when it affects the home’s air quality. Usually, the spray foam seals all potential outlets where air leaks may occur. This means that your heating and cooling will improve significantly. Unfortunately, there is a downside to this since the air in the room will easily get contaminated when there is no fresh air coming infrequently. It interferes with adequate ventilation, especially in the attic. While you may not have known this before, the chances are that the leak in the attic allowed fresh air to flow into your home space. Now that there are no more leaks, there is a high likelihood that impurities accumulate in the air. It may be necessary to introduce controlled mechanical ventilation. You should consider shopping for dehumidifiers or energy recovery ventilators to balance the air again. Choosing to use spray foam insulation comes with both gains and demerits that users should be willing to accommodate. However, you should only consider installing either of the two gadgets at home if the blower test you carry out registers negative results. It is possible that the foam insulation may have reduced ventilation about not to unacceptable levels. Only turn to drastic air balancing measures if the ventilation levels have dropped beyond acceptable healthy levels. Alternatively, speak to your HVAC experts to know if you may need to change the entire ventilation altogether.
