At Green Attics HVAC & Attic Insulation, located at 4645 Wyndham Ln Suite 110, Frisco, TX 75033, we often hear this common question: “What is the average cost of attic insulation?” Understanding attic insulation costs is critical for homeowners aiming to improve energy efficiency, reduce utility bills, and maintain indoor comfort year-round. This guide offers a detailed cost breakdown, including the types of insulation, influencing factors, long-term savings, and why attic insulation is a smart investment.

Why Attic Insulation Matters for Frisco, TX Homes


In Frisco, Texas, our scorching summers and fluctuating winters make attic insulation a critical element of a home’s energy system. Proper attic insulation helps reduce HVAC load, improve indoor air quality, and significantly cut down electricity bills. It also increases home resale value and prolongs the life of your HVAC system.

Average Cost of Attic Insulation in 2025


The average cost of attic insulation in the U.S. ranges from $1.50 to $3.50 per square foot, depending on the insulation type and your attic's size and condition. For most Frisco-area homes, the typical investment falls between $1,500 and $4,000.

























Home Size (sq. ft.) Estimated Cost Range
1,000 $1,500 – $2,500
1,500 $2,250 – $3,500
2,000 $3,000 – $4,500
2,500+ $3,750+

These costs include materials, labor, cleanup, and removal of old insulation (if needed).

Types of Attic Insulation and Their Costs


Each insulation material has its pros, cons, and price range. Below is a breakdown of the most commonly used attic insulation types in Texas.

1. Blown-In Fiberglass Insulation



  • Cost: $1.00 – $2.20 per sq. ft.

  • R-Value per inch: 2.2 – 2.7

  • Ideal for: Attics with irregular joist spacing and obstructions


Blown-in fiberglass is a cost-effective, non-flammable, and easy-to-install material widely used in retrofitting existing attics.

2. Cellulose Insulation



  • Cost: $1.50 – $2.80 per sq. ft.

  • R-Value per inch: 3.2 – 3.8

  • Eco-friendly: Made from recycled paper treated with fire-retardant


Cellulose insulation is excellent for sealing air leaks and works well in older homes where thermal performance is crucial.

3. Spray Foam Insulation



  • Cost: $3.00 – $6.50 per sq. ft.

  • R-Value per inch: 6.0 – 7.0 (Closed-cell), 3.5 – 4.5 (Open-cell)

  • Best for: Maximum air sealing, moisture protection, and HVAC efficiency


Though more expensive, spray foam delivers superior insulation performance and can drastically reduce energy costs.

4. Batt Insulation (Fiberglass Rolls)



  • Cost: $0.80 – $1.80 per sq. ft.

  • R-Value per inch: 2.9 – 3.8

  • Use case: New construction or large attics with open joists


Batt insulation is ideal for DIY installations and budget-conscious homeowners, though it may not seal gaps as effectively as other methods.

Factors That Influence the Cost of Attic Insulation


1. Attic Size & Accessibility


A large attic or one with tight access points, HVAC ducts, or low ceilings may require more labor, increasing costs.

2. Type of Insulation


Spray foam costs significantly more than cellulose or fiberglass, but it offers higher energy efficiency and longer lifespan.

3. Removal of Existing Insulation


Old or damaged insulation—especially if it contains mold or pests—must be removed before installation. This can add $1 to $2 per sq. ft. to your total cost.

4. Labor and Local Rates


Professional installation is often the best choice to ensure code compliance and optimal performance. Labor rates in Frisco, TX typically range from $0.60 to $1.20 per sq. ft. depending on complexity.

Signs Your Home Needs New Attic Insulation


If you're unsure whether to insulate your attic, watch for these warning signs:

  • High energy bills during winter or summer

  • Inconsistent room temperatures

  • Drafts or cold air near the ceiling

  • Pest infestations or damaged insulation

  • HVAC system running longer than usual

According to the U.S. Department of Energy:

  • Proper insulation in an attic can reduce heating and cooling bills by up to 20%.

  • Spray foam insulation may offer ROI in less than 5 years through energy savings alone.
