Blown In Insulation Cost: A Comprehensive Guide for Homeowners in Long Island, Brooklyn, and Queens

When it comes to improving energy efficiency and reducing heating and cooling costs, insulation plays a crucial role. One of the most effective and affordable insulation options available today is blown-in insulation. But how much does it cost? If you’re in Long Island, Brooklyn, or Queens and wondering about blown in insulation cost, this guide will provide you with all the details you need.

What Is Blown-In Insulation?

Blown-in insulation, also known as loose-fill insulation, consists of tiny insulating particles made from fiberglass, cellulose, or mineral wool. These materials are blown into walls, attics, and other spaces using specialized equipment, ensuring full coverage and improved thermal performance.

Factors Affecting Blown-In Insulation Cost

The cost of blown-in insulation can vary depending on several factors. Understanding these will help you estimate how much you might need to invest in insulating your home.

Types of Blown-In Insulation Materials & Their Costs

Blown-in insulation comes in three primary types: fiberglass, cellulose, and mineral wool. Each material has different properties, benefits, and price points, making it essential to choose the right one based on budget, performance, and insulation needs.

 

1. Fiberglass Blown-In Insulation

Fiberglass is the most widely used and affordable type of blown-in insulation. It consists of tiny glass fibers that are lightweight and provide decent thermal resistance (R-value).

Benefits:
✅ Cost-effective – Cheapest among all blown-in insulation materials.
✅ Non-combustible – Doesn’t catch fire easily.
✅ Lightweight – Puts less pressure on attic structures.
✅ Moisture-resistant – Less prone to mold growth.

Drawbacks:
❌ Lower R-Value per inch compared to cellulose and mineral wool.
❌ Can be itchy to handle – Requires protective gear for installation.
❌ Not as eco-friendly – Made from synthetic materials.

Cost:

• Material cost: $0.50 to $1.00 per square foot
• Installed cost (including labor): $1.00 to $1.50 per square foot

Best For:

• Budget-conscious homeowners
• Attics, walls, and crawl spaces
• Areas with moderate insulation needs

 

2. Cellulose Blown-In Insulation

Cellulose insulation is made from recycled paper products treated with fire-resistant chemicals (like boric acid). It has a higher R-value than fiberglass and is an excellent choice for eco-conscious homeowners.

Benefits:
✅ Higher R-value per inch (R-3.2 to R-3.8) – Provides better insulation than fiberglass.
✅ More eco-friendly – Made from up to 85% recycled materials.
✅ Good fire resistance – Treated with flame retardants.
✅ Better at sealing air gaps than fiberglass.

Drawbacks:
❌ More expensive than fiberglass
❌ Heavier material – May require additional attic support.
❌ Can absorb moisture – Leading to potential mold issues if not properly installed.

Cost:

• Material cost: $0.70 to $1.50 per square foot
• Installed cost (including labor): $1.50 to $2.50 per square foot

Best For:

• Older homes (great for retrofitting)
• Attic insulation (better air sealing than fiberglass)
• Environmentally-conscious homeowners

3. Mineral Wool (Rock Wool) Blown-In Insulation

Mineral wool (also called rock wool or slag wool) is made from natural rock or industrial byproducts melted and spun into fiber form. It is the most expensive of the three but offers superior soundproofing, fire resistance, and durability.

Benefits:
✅ Highest R-value per inch (R-3.7 to R-4.2) – Better thermal insulation than fiberglass or cellulose.
✅ Superior fire resistance – Can withstand temperatures above 1,800°F.
✅ Excellent soundproofing – Ideal for urban areas like Brooklyn and Queens.
✅ Moisture-resistant – Does not retain water or promote mold growth.

Drawbacks:
❌ Most expensive option
❌ Heavier than fiberglass and cellulose
❌ Limited availability – Fewer contractors specialize in it.

Cost:

• Material cost: $1.00 to $2.00 per square foot
• Installed cost (including labor): $2.00 to $3.00 per square foot

Best For:

• Homes in noisy areas (Brooklyn & Queens)
• Fire-prone areas
• High-performance insulation needs

Which Blown-In Insulation Should You Choose?

🔹 On a budget? → Go with fiberglass
🔹 Want eco-friendly & better air sealing? → Choose cellulose
🔹 Need maximum fire resistance & soundproofing? → Opt for mineral wool
