Understanding Air Sealing and Its Importance
Air sealing is a fundamental step in improving the energy efficiency of buildings. Uncontrolled air leakage can lead to increased heating and cooling costs, moisture problems, and reduced indoor comfort. Traditional insulation methods like fiberglass batts or cellulose may not effectively block air movement, making spray foam insulation a superior solution.
How Spray Foam Works as an Air Sealant
Spray foam insulation expands upon application, filling cracks, gaps, and voids that traditional insulation cannot reach. This expansion creates a continuous barrier that prevents air leakage, enhancing thermal performance and indoor air quality. Its ability to conform to irregular shapes makes it ideal for insulating attics, walls, crawl spaces, and other hard-to-reach areas.
Benefits of Spray Foam for Air Sealing
1. Superior Energy Efficiency
By eliminating air leaks, spray foam insulation significantly reduces energy loss. Homes and businesses experience lower heating and cooling costs, often resulting in energy savings of up to 50% compared to traditional insulation methods.
2. Enhanced Indoor Comfort
A properly air-sealed home maintains consistent indoor temperatures. Spray foam prevents drafts, hot and cold spots, and humidity fluctuations, creating a more comfortable living and working environment year-round.
3. Moisture and Mold Prevention
Air leaks allow moisture to infiltrate walls, leading to mold growth and structural damage. Spray foam acts as a moisture barrier, reducing the risk of mold and improving indoor air quality. Closed-cell spray foam, in particular, provides added moisture resistance, making it suitable for humid climates.
4. Improved Indoor Air Quality
By sealing gaps and cracks, spray foam prevents outdoor pollutants, allergens, and dust from entering the indoor space. This is particularly beneficial for individuals with allergies or respiratory conditions.
5. Increased Structural Integrity
Closed-cell spray foam strengthens walls and roofs by adding rigidity. This added support enhances the durability of the structure, offering extra protection against strong winds and extreme weather conditions.
6. Long-Lasting Performance
Unlike traditional insulation, which can sag, settle, or degrade over time, spray foam maintains its effectiveness for decades. Once applied, it remains intact, ensuring long-term energy efficiency and air-sealing benefits.
Choosing the Right Type of Spray Foam
Spray foam insulation comes in two primary forms:
Open-Cell Spray Foam
- Expands more, making it ideal for filling large cavities.
- Provides excellent soundproofing.
- More affordable than closed-cell foam.
- Offers some air sealing but allows moisture permeability.
Closed-Cell Spray Foam
- Denser and more rigid, adding structural strength.
- Highly effective as an air and moisture barrier.
- Higher R-value per inch, making it ideal for maximizing insulation in limited space.
- Suitable for exterior applications and flood-prone areas.
Where to Use Spray Foam for Maximum Air Sealing
Spray foam can be applied in various parts of a building to enhance energy efficiency:
Attics and Roof Decks
- Prevents heat loss in winter and heat gain in summer.
- Reduces the risk of ice dams.
- Enhances roof durability by minimizing moisture buildup.
Walls and Wall Cavities
- Stops drafts and temperature fluctuations.
- Improves soundproofing between rooms.
Crawl Spaces and Basements
- Prevents cold air infiltration from the ground level.
- Reduces moisture-related issues, such as mold and mildew.
Gaps Around Doors, Windows, and Electrical Outlets
- Enhances overall insulation efficiency.
- Seals small cracks that contribute to air leaks.
Why Homeowners and Businesses Prefer Spray Foam
Spray foam insulation is increasingly popular among homeowners and businesses due to its long-term benefits. While the upfront cost may be higher than traditional insulation, the energy savings, durability, and comfort improvements make it a worthwhile investment. Many property owners find that spray foam insulation pays for itself over time through reduced utility bills and maintenance costs.
Professional Installation Matters
While DIY spray foam kits are available, professional installation ensures optimal performance. Experts apply the foam evenly, avoiding over-expansion or gaps that could reduce effectiveness. Certified installers also follow safety protocols, ensuring a secure and efficient application.

Frequently Asked Questions (FAQs)
How long does spray foam insulation last?
Spray foam insulation is designed to last for decades without sagging or deteriorating. Its durability makes it a long-term solution for air sealing and energy efficiency.
Is spray foam insulation safe for indoor use?
Yes, once cured, spray foam insulation is safe and does not emit harmful chemicals. Proper ventilation during installation ensures any fumes dissipate quickly.
Does spray foam insulation increase home value?
Yes, energy-efficient upgrades, including spray foam insulation, can enhance property value by reducing utility costs and improving overall comfort.
Can spray foam be applied over existing insulation?
In some cases, spray foam can be applied over existing insulation, but it is best to consult a professional to determine the most effective approach.
What is the cost of spray foam insulation?
Costs vary depending on the size of the area and type of spray foam used. Contacting Polyco Spray Foam Insulation for a quote ensures accurate pricing for your specific needs.
Is closed-cell or open-cell spray foam better?
Closed-cell spray foam provides a higher R-value and moisture resistance, making it ideal for exterior applications and humid environments. Open-cell foam is better for soundproofing and interior walls.
Does spray foam insulation prevent pests?
While spray foam does not repel pests, it seals gaps that insects and rodents might use to enter a building.
How soon can you re-enter a home after spray foam is installed?
Most installations require a 24-hour curing period before re-entry to allow the foam to fully expand and any fumes to dissipate.
