If your home still relies on fiberglass or cellulose insulation, it might be time for an upgrade. At Therm-Con, we offer high-performance spray foam insulation for Chattanooga homes and businesses. Spray foam creates an airtight seal, reducing energy waste, improving indoor air quality and helping control moisture. Unlike traditional materials, it won’t sag or settle over time.

What Is Spray Foam Insulation?
Emerging in the 1980s as a game-changer in insulation, spray foam insulation is now known as one of the best ways to seal and insulate Chattanooga homes. It’s made by combining two liquids that expand into a durable foam, filling gaps in walls, ceilings and floors to prevent air leaks.
There are two types: open-cell, which expands to fill every crevice, and closed-cell, which creates a dense, continuous barrier.
Unlike traditional insulation like fiberglass and cellulose, spray foam doesn’t just sit in place — it actively seals gaps around electrical outlets, light fixtures and even where walls meet doors and windows.
This means better energy efficiency, fewer drafts and moisture control to prevent mold. Whether you’re building a new home in Ooltewah or upgrading an older one in North Chattanooga, spray foam insulation makes a noticeable difference.
Benefits of Spray Foam Insulation
Chattanooga’s hot, humid summers and chilly winters make energy efficiency a challenge. Spray foam insulation provides an airtight seal, reducing energy loss by up to 30% compared to traditional insulation. In a Hixson home, for example, upgrading from fiberglass to spray foam will cut cooling costs noticeably, keeping indoor temperatures stable even during 90-degree July afternoons.
Unlike fiberglass, spray foam blocks moisture, preventing mold issues common in older homes near the Tennessee River.
During winter, homes in Signal Mountain often struggle with drafts, but spray foam seals every gap, keeping heating costs down.
The Department of Energy estimates up to 40% of a home’s energy loss is due to air leaks — something spray foam prevents.
Whether you’re upgrading an existing home or insulating a new build, spray foam provides a wealth of benefits. From keeping your home quieter to blocking allergens and pests from getting inside, spray foam installation keeps your home safe and comfortable year-round.

Spray Foam Insulation Process FAQs
Is the spray foam insulation process a good choice for older Chattanooga homes?
Absolutely! Many older homes have inefficient insulation that lets air leak in and out. Upgrading to spray foam seals those gaps, improves energy efficiency and helps control moisture, which is perfect for Chattanooga’s humid summers and chilly winters.
Can spray foam be added to new construction homes?
Yes, and it’s one of the best investments you can make. Our team applies spray foam directly to the walls, roofline and other key areas before drywall goes up. It expands to fill every gap, creating an airtight barrier that boosts energy efficiency and moisture control from day one.
Can spray foam be applied over old insulation?
In some cases, yes, but it depends on the condition of the existing insulation. Our Therm-Con team will assess your current setup and recommend whether removal is needed to ensure the best seal and performance.
