How Closed-Cell Spray Foam Insulation Improves Air Quality Indoors
With the naked eye, it is impossible to determine the state of your air quality. This is why indoor air quality often goes overlooked by property owners, even though it is vital to the safety of occupants. When dust, allergens, mold spores and other pollutants enter the air, they can cause health issues, especially amongst those with environmental allergies. But what options are available to improve this? Spray foam insulation in Toronto, particularly closed-cell insulation, offers more than energy efficiency and indoor comfort; it can also improve indoor air quality. Spray foam insulation costs are a valuable investment into your property or home’s comfort, health and safety. Contact EcoStar Insulation to get started!
What Is Closed-Cell Spray Foam Insulation?
Spray foam insulation is a liquid insulation that is spray-applied to the surfaces of your property. Once it dries down, it creates an airtight seal that helps prevent heat loss or moisture infiltration. Closed-cell insulation, in particular, is dense and rigid with closed pores. This gives it an excellent R-value of 7. This closed-cell structure also makes this insulation an excellent water-barrier and vapour-barrier. Overall, closed-cell spray foam insulation is the most effective insulation on the market, allowing it to enhance comfort, efficiency and even air quality.
How Air Leaks Impact Indoor Air Quality
Indoor air quality issues are usually the result of air leaks from a lack of or poor insulation. Unsealed gaps in the structure of your property allow outdoor pollutants, allergens, and humidity to enter your home. Air leaks can spread mold, dust and allergens throughout your home, leading to allergy attacks, itchiness and skin irritation.
How Spray Foam Insulation Improves Air Sealing & Reduces Pollutants
Standard insulations do not offer an airtight seal comparable to spray foam; this is why a closed-cell spray foam insulation is the optimal solution for improving indoor air quality. Spray foam insulation envelopes your entire property, preventing outdoor pollutants from entering your home. The closed-cell structure acts as a barrier against both air and moisture, giving you better control over indoor airflow.
Moisture Control and Mold Prevention
Excess humidity in a property is the leading cause of mold. Since closed-cell spray foam insulation is water-resistant and naturally acts like a moisture barrier, it can help control humidity and prevent mold.
Leak Protection
Closed-cell spray foam creates a seamless, waterproof barrier that blocks air and moisture leaks before they can enter your walls or attic. This helps protect your building structure against rotting and deterioration. By preventing water intrusion and condensation, you also reduce the conditions mold needs to grow. With less mold and mildew in your building, indoor air stays cleaner, healthier, and easier to breathe.
