Spray Foam Insulation: The Ultimate Barrier Against Summer Heat

As summer temperatures rise across the Delaware Valley, many homeowners are looking for ways to keep their homes cool and comfortable without skyrocketing energy bills. One of the most effective solutions? Spray foam insulation. Known for its superior sealing power and thermal resistance, spray foam insulation has quickly become a top choice for energy-conscious property owners.

In this blog, Koala Insulation of Delaware Valley explores how spray foam acts as the ultimate barrier against summer heat, why it outperforms traditional insulation materials, and how it can save you money and improve comfort in your home.

What Is Spray Foam Insulation?

Spray foam insulation is a type of insulation material that is sprayed into walls, attics, and crawl spaces. It expands on contact, filling gaps, cracks, and crevices to create an airtight seal. At Koala Insulation of Delaware Valley, we offer two primary types of spray foam: open-cell and closed-cell.

• Open-cell spray foam is lighter and more flexible, offering excellent sound dampening properties.
• Closed-cell spray foam is denser and provides a higher R-value (thermal resistance), making it ideal for extreme temperature control and moisture resistance.

Both types offer unique advantages, and the team at Koala Insulation of Delaware Valley can help determine which is best suited for your specific application.

Why Spray Foam Beats the Summer Heat

The Delaware Valley can experience hot and humid summers, which means your home’s insulation needs to do more than just sit in the walls—it needs to actively combat heat transfer. Here’s how spray foam excels in that role:

1. Superior Thermal Resistance

The R-value measures an insulation material’s ability to resist heat flow. Spray foam, especially closed-cell, has one of the highest R-values per inch of any insulation type. This means it can more effectively prevent hot outdoor air from infiltrating your home and keep your cool indoor air from escaping.

2. Air Sealing Power

Traditional insulation like fiberglass batts can leave gaps around outlets, wiring, and wall joints, allowing warm air to seep in. Spray foam expands to fill all these gaps, creating a near-perfect air seal. This reduces drafts and helps your HVAC system work less, especially during peak summer months.

3. Moisture Control

Humidity is a major issue in the Delaware Valley. Spray foam insulation acts as a moisture barrier, reducing the risk of mold, mildew, and structural rot. Closed-cell foam is especially beneficial in crawl spaces and basements, where moisture problems are most common.

4. Durability and Longevity

Unlike other forms of insulation that can sag, settle, or degrade over time, spray foam insulation maintains its structure for decades. Once installed by Koala Insulation of Delaware Valley, it continues to perform without needing maintenance or replacement.

Key Areas to Install Spray Foam Insulation

To maximize your home’s resistance to summer heat, strategic installation is key. At Koala Insulation of Delaware Valley, we often recommend installing spray foam in the following areas:

▪ Attics

The attic is one of the biggest sources of heat gain in a home. Spray foam can be applied to the underside of the roof deck to create a thermal envelope that keeps attic temperatures significantly lower.

▪ Walls

Walls, especially in older homes, can leak a lot of air. Spray foam insulation in wall cavities creates an air-tight barrier that improves temperature consistency throughout your home.

▪ Basements and Crawl Spaces

These areas can be cool in the winter but humid and muggy in the summer. Spray foam helps control both temperature and moisture.
