Spray Foam Vs Blown-In Insulation: Cost & R-Values Compared

2/12/2024 9:00 AM

Key Takeaways

• Spray foam insulation costs between $2.00 and $9.00 per square foot, while blown-in insulation is more affordable, at $1.50 to $4.00 per square foot.

• Spray foam creates an airtight seal, reducing energy costs by up to 50%, whereas blown-in insulation improves energy efficiency but lacks air-sealing capabilities.

• Spray foam requires professional installation, while blown-in insulation is DIY-friendly and simpler to install.

• Spray foam is effective at sealing gaps but is more expensive, while blown-in insulation is cost-effective for large spaces but doesn’t seal air leaks.

• USA Spray Me has been providing expert insulation services in Northern California for over 19 years, specializing in both spray foam and blown-in insulation.

Introduction to Spray Foam and Blown In Insulation

Spray foam and blown-in insulation are widely used to enhance energy efficiency. Choosing the right insulation depends on factors like cost and R-value performance.

Overview

Spray foam insulation:

• Expands to seal gaps and cracks.

• Provides a strong air barrier.

• Best for irregular or hard-to-reach spaces.

Blown-in insulation:

• Made from cellulose or fiberglass.

• Quickly fills large areas.

• Suitable for attics or wall cavities.

Both options reduce heat transfer, improving comfort and lowering energy costs by minimizing heating and cooling system usage.

Cost Comparison

Installation Costs

Spray foam insulation typically costs between $2.00 and $9.00 per square foot, reflecting its complex application and the materials involved. The higher range is due to the professional expertise required for proper installation. Blown-in insulation, at $1.50 to $4.00 per square foot, is more budget-friendly and suitable for DIY projects - potentially reducing labor costs.

Insulation Type	Cost per Square Foot	Installation Complexity
Spray Foam	$2.00 - $9.00	High (Professional Installation Recommended)
Blown-In	$1.50 - $4.00	Low (DIY Friendly)

Long-term Savings

Despite the higher upfront cost, spray foam often pays off over time due to its superior air-sealing properties. It minimizes air leaks, enhancing the efficiency of heating and cooling systems - potentially recouping the initial investment through lower energy bills within a few years.

Pros and Cons: Blown-in insulation

• Cost-effective for large areas

• Quick and easy installation

• Made from recycled materials

• Provides good soundproofing

Blown-in insulation is a lower-cost option for large spaces - it works well in attics and walls, nd is made from materials like cellulose or fiberglass. However, it doesn’t seal air leaks like spray foam, which can reduce efficiency over time in older homes with gaps.

Advantages

• Cost-effective for large areas without high expenses.

• Sustainable option using recycled materials.

Disadvantages

• Can settle over time, reducing its insulating capacity.

• Doesn’t seal air leaks, resulting in drafts and potential energy loss.

Energy Efficiency

Energy efficiency affects how well a building retains heat in winter and stays cool in summer - directly impacting energy bills. Spray foam and blown-in insulation offer different energy-saving benefits.

Spray Foam Efficiency

Spray foam insulation fills every crevice - creating an airtight seal that reduces heat transfer and prevents air leaks.

• Can reduce energy costs by up to 50%.

• Higher upfront cost, but significant long-term savings.

Blown-In Insulation Efficiency

Blown-in insulation improves energy efficiency but lacks the sealing capabilities of spray foam.

• Effectively covers large areas, filling attics and walls.

• Doesn’t form an airtight seal, which may lead to energy loss.

• Regular maintenance and sealing help reduce this issue.

• Cost-effective for spaces with limited access.

Installation Process

• Spray Foam: Requires specialized equipment and expertise.

• Blown-In Insulation: Can often be installed as a DIY project.

Steps for Installing Spray Foam Installation

Spray foam installation requires multiple stages:

1. Assessment: A professional evaluates the area to determine the right type and quantity of foam.

2. Preparation: Large gaps are sealed, and non-target surfaces are covered to prevent foam contact.

3. Application: Foam is sprayed into the designated area, expanding to create a solid barrier.

Steps for Installing Blown-In Insulation

Installing blown-in insulation is a simpler process:

1. Acquire Blower Machine: Rent or purchase a blower machine.

2. Feed Insulation: Feed the insulation material into the machine.

3. Apply Evenly: Direct the material into the desired area, such as an attic or wall cavity, ensuring even coverage without gaps.

Blown-in insulation suits DIY enthusiasts since it requires less specialized equipment.

Choosing the Right Insulation for Your Project

Spray foam provides superior energy efficiency and long-term results, making it ideal for those focused on maximum performance. In contrast, blown-in insulation is cost-effective and easier to install, especially for large spaces.

Recommendation

• Spray Foam Insulation: Best for those seeking maximum energy efficiency and long-term benefits. While it requires professional installation, it offers exceptional insulation properties and reduced energy costs over time.

• Blown-In Insulation: Ideal for those on a budget or tackling large areas. It’s affordable and suitable for DIY installation.
