About Spray Foam Insulation

Spray foam insulation has rapidly gained popularity among homeowners and businesses looking to improve energy efficiency, comfort, and long-term performance. At Allied Insulation & Supply, we’re proud to offer professional spray foam insulation services that provide a tighter seal and better protection than many traditional insulation options.

Whether you’re new to spray foam or already familiar with its benefits, our team is here to guide you through the process and ensure you experience the full advantages of this cutting-edge insulation material.

What Is Spray Foam Insulation?

Spray foam insulation is a polyurethane-based material that expands upon application to fill cracks, gaps, and hard-to-reach spaces within walls, attics, crawlspaces, or other structures. This expansion creates a continuous air barrier, preventing unwanted drafts, moisture intrusion, and heat transfer. Its versatility makes it ideal for new construction, retrofits, and remodeling projects where traditional insulation might not offer a complete seal.

Benefits of Using Spray Foam Insulation

Spray foam originated in the 1940s with German chemist Otto Bayer's development of polyurethane. Its lightweight and durable properties led to widespread use for various applications. By the 1970s, the construction industry began utilizing its insulating capabilities to minimize air leaks in buildings. Today, improved materials and techniques have established spray foam as a leading insulation solution.

Spray foam insulation seals gaps, maintaining stable indoor temperatures and reducing heating and cooling strain. This efficiency often leads to significant savings on energy bills, making it a worthwhile investment.
Unlike fiberglass batts or loose-fill insulation, spray foam expands to fill all the hidden voids in your walls, ceilings, or floors. This creates a strong barrier against drafts, pollen, dust, and other airborne irritants, improving indoor air quality and comfort.
Moisture infiltration can lead to mold, mildew, and structural damage over time. Spray foam’s closed-cell variation is particularly effective at resisting water penetration, helping you avoid costly repairs and preserving the longevity of your property.
The density of spray foam helps dampen outside noise, creating a quieter indoor environment. Whether you’re trying to mute the hustle of a busy street or simply want more privacy between rooms, spray foam can help reduce unwanted sound transmission.
Spray foam’s rigid structure and strong adhesive qualities mean it adheres securely to building materials, resisting settling or sagging. Once properly installed and cured, it maintains its insulating properties for years, giving you peace of mind that your home or workplace is protected for the long haul.

Types of Spray Foam Insulation

Open Cell Spray Foam Insulation

Open-cell spray foam insulation features partially open cells that allow air to fill the spaces inside. It expands to fill voids and adapt to uneven surfaces, forming an effective barrier against air and heat. This insulation also dampens sound and improves energy efficiency and indoor comfort.

Closed Cell Spray Foam Insulation

Closed-cell spray foam insulation is a dense, rigid material that prevents air and moisture infiltration. It enhances thermal resistance, improving energy efficiency and indoor comfort, and is suitable for damp or humid environments.
