As the insulation stops external weather conditions from entering the home and the internal atmosphere can’t exit, the inside air becomes contaminated and polluted due to various chemicals. Further, as the building residents inhale oxygen, they exhale carbon dioxide that pollutes the air within the building. The stale air from the washroom, baths, Kitchen, cleaning products, appliances, heating, and cooling systems also add their share to pollute the atmosphere of an insulated residential building. These scenarios lead to health issues, including asthma, allergies, respiratory issues, and other health-related problems. The solution to this is a well-designed and balanced ventilation system that can throw the stale, polluted air out of the house to have a fresh and healthy living environment for building residents.
