Since steel insulated panels form airtight seals, they prevent air from entering and exiting a building. This makes it easier to create a controlled indoor environment. A controlled environment allows you to manage the humidity and amount of air entering and leaving your home. This can create the highest IAQ and healthiest indoor environment. SIPs also limit air exchange to ventilation systems, filtering and dehumidifying incoming air. The process eliminates dust mites, mold spores and other allergens, which can improve IAQ even more.
