High-Performance Spray Foam Insulation

Stop Energy Loss with High-Performance Spray Foam

Most homes lose energy through small gaps and air leaks you can’t see. Traditional insulation only slows that down—spray foam stops it completely.

Spray foam expands to seal every crack and opening in your attic, walls, and rim joists, creating an airtight barrier that keeps heat in during winter and out during summer.

If you’ve noticed high energy bills, uneven temperatures, or drafts, upgrading to spray foam can make a major difference.

Spray Foam Insulation

Spray foam insulation creates a sealed barrier that stops air leaks, moisture intrusion, and energy loss at the source. Unlike traditional insulation, it expands to fill every gap—helping your home stay warmer in the winter and cooler in the summer.

At Winnebago Exteriors, we install spray foam systems designed for Wisconsin homes, giving you better comfort, lower energy bills, and long-term performance.

✔ Seals air leaks and drafts

✔ Improves energy efficiency

✔ Helps prevent moisture and mold issues

Insulation FAQ

Spray foam is most effective when applied to areas with the highest air leakage and heat transfer.

Common high-impact areas include:

Attic roof deck (creating an unvented conditioned attic)

Rim joists and band boards

Wall cavities in remodel or new construction

Crawl spaces and basement walls

Targeting these areas helps create a continuous thermal and air boundary, which is critical for performance.

Spray foam insulation provides both thermal resistance (R-value) and an air barrier, which is something fiberglass and cellulose do not fully achieve.

Air leakage is responsible for a large portion of energy loss in most homes. Spray foam expands to seal penetrations, joints, and gaps, reducing uncontrolled air movement.

Key performance advantages:

Higher effective R-value per inch

Air sealing in one application

Reduced thermal bridging when properly installed

Improved indoor humidity control

This results in a more stable indoor environment and improved overall building efficiency.

Yes—especially with spray foam.

Homes with poor insulation can lose a significant amount of heated or cooled air, forcing your HVAC system to work harder. That means higher monthly bills.

Traditional insulation can settle, shift, or lose effectiveness over time.

Spray foam insulation is different—it doesn’t sag or break down like fiberglass, and it maintains its performance for decades.

That means:

Long-term energy savings

Consistent comfort

Less need for future upgrades

It’s a one-time upgrade that continues to pay off.
