Best Practices for Installing Spray Foam Insulation in Older Homes

Older homes have history, charm, and character, but they also have drawbacks, particularly in terms of energy efficiency. Older insulation, uneven walls, and drafty attics can result in uncomfortable living quarters and high energy costs. Spray foam insulation is among the best ways to address these issues. However, proper installation in older homes necessitates preparation, skill, and attention to detail. Here’s a guide to the best practices.

5 Best Practices for Installing Spray Foam Insulation in Older Homes

1. Understand Spray Foam Insulation Benefits

Spray foam insulation is not just another way to insulate—it offers multiple advantages over traditional insulation:

• Superior Air Sealing: It expands on application, sealing gaps and cracks that older homes often have.

• Energy Efficiency: By reducing air leaks, it can lower heating and cooling costs significantly.

• Moisture Barrier: Helps prevent mold and mildew, a common problem in older homes.

• Structural Support: Closed-cell spray foam can add rigidity to walls and roofs.

Knowing these benefits helps homeowners appreciate why professional installation is crucial.

2. Inspect and Prepare the Space

Before installation, inspect your home for:

• Existing insulation: Remove or assess old insulation to ensure proper adhesion.

• Structural issues: Fix leaks, rot, or damaged wood to avoid trapping moisture.

• Electrical and plumbing systems: Make sure wires and pipes are safe and accessible.

Preparation ensures the spray foam works effectively and lasts longer.

3. Choose the Right Type of Spray Foam

• Open-Cell Spray Foam Installation: Soft, flexible, and ideal for interior walls and areas where moisture control isn’t critical.

• Closed-Cell Spray Foam Installation: Dense, water-resistant, and perfect for attics, basements, and exterior walls.

For older homes, a combination of both might be ideal—attic spray foam insulation with closed-cell foam for energy efficiency and moisture protection.

4. Hire the Best Spray Foam Installers in DFW

Spray foam insulation is a precision job. Hiring experienced professionals ensures:

• Correct application thickness and coverage.

5. Safety First

• Ensure proper ventilation during and after installation.

• Follow manufacturer guidelines for curing and occupancy.

• Protect yourself with gloves, masks, and safety glasses if doing minor DIY inspections.

Safety precautions prevent health risks and preserve indoor air quality.
