Stop losing heat through your attic. Patriot Spray Foam Insulation provides professional attic insulation for homes and commercial buildings across Delaware and beyond — with same-day and next-day service available.

Introduction / Why Attic Insulation Matters

Why Attic Insulation Is the Single Most Important Upgrade for Your Home

Your attic is responsible for up to 25% of your home’s total heat loss. In the hot summers and freezing winters that Delaware homeowners face, an under-insulated attic means your HVAC system works overtime — and your energy bills prove it.

The good news: professional attic insulation is the highest-ROI home improvement available. Most homeowners see energy savings of 20–40% within the first year. Patriot Spray Foam Insulation specializes in diagnosing exactly what your attic needs and delivering a solution that lasts the life of your home.

Whether your attic is completely uninsulated, using old fiberglass batts that have settled and lost effectiveness, or has moisture problems from poor air sealing — we have the right solution and the expertise to apply it correctly.

Attic Insulation Services Offered

Complete Attic Insulation Solutions for Every Home & Structure

Spray Foam Attic Insulation

The most effective solution for air sealing and insulation in one application. Closed-cell spray foam creates a complete air barrier on your attic floor or roof deck, delivering the highest R-value per inch available. Ideal for attics with significant air leakage, moisture problems, or extreme temperature exposure.

  • Open-cell or closed-cell depending on your attic configuration
  • Seals every gap, crack, and penetration — eliminating drafts completely
  • Adds structural rigidity to your roof deck (closed-cell)
  • Prevents moisture infiltration and mold growth
  • Does not sag, settle, or lose effectiveness over time

Blown-In Attic Insulation

The most cost-effective option for adding R-value to existing attic floors. Blown-in insulation (loose-fill fiberglass or cellulose) fills irregular spaces and covers existing insulation to bring your attic up to current energy code requirements.

  • Ideal for existing homes with partial insulation
  • Fast installation — most attics completed in one day
  • Fills around obstructions and irregular joists automatically
  • Can be layered over existing fiberglass batts
  • Most affordable option for simple R-value improvements

Attic Air Sealing

Before adding insulation, air sealing is the most critical step — and the one most contractors skip. Every gap around plumbing penetrations, electrical boxes, recessed lights, and framing creates a direct path for conditioned air to escape and outside air to enter.

  • Full diagnostic assessment of your attic air leakage points
  • Sealing of all penetrations before insulation is applied
  • Dramatically improves the effectiveness of any insulation type
  • Required for maximum energy savings and moisture control
  • Often overlooked by contractors — never skipped by Patriot

Attic Insulation Removal & Replacement

Old, damaged, or rodent-contaminated insulation must be removed before new insulation is installed. Leaving compromised insulation in place reduces effectiveness and can create ongoing moisture and air quality problems.

  • Full removal of old fiberglass batts, blown-in, or damaged insulation
  • Sanitation and treatment for rodent or moisture damage
  • Inspection for underlying structural or moisture issues
  • Clean install of new, properly specified insulation

⭐ Patriot Difference: We assess your attic as a complete system — not just insulation depth. Air sealing, ventilation, moisture management, and insulation type are all evaluated together before we quote a single dollar.

FAQ

FAQ — Attic Insulation

What R-value does my attic need?

The U.S. Department of Energy recommends R-38 to R-60 for attics in Climate Zone 4 (Delaware, southern New York, and New Jersey). If your current insulation is below R-30, upgrading is likely to pay for itself within 3–5 years through energy savings.

Yes — in most cases. Blown-in insulation and open-cell spray foam can be applied over existing materials as long as the existing insulation is dry, undamaged, and free of mold or pest contamination. We assess this during the free estimate.

Most residential attic insulation projects are completed in one day. Larger homes or projects requiring removal of existing insulation may take two days. We provide a specific timeline before we begin.

Yes. Attic insulation is equally effective at preventing heat gain in summer as it is at preventing heat loss in winter. A properly insulated and air-sealed attic keeps conditioned air inside year-round, reducing HVAC runtime in every season.

Yes. Patriot Spray Foam Insulation handles residential homes, multi-family buildings, commercial warehouses, and industrial facilities. Our equipment and team are scaled for projects of any size across Delaware.
