What is Blow In Insulation?
Blow in insulation is a type of insulation sprayed into place using specialized equipment. It’s made from cellulose, fiberglass, or mineral (rock or slag) wool. These materials are highly resistant to heat flow.
Understanding Blown In Attic Insulation
Blown in insulation is ideal for attics with irregular joist spacing or numerous obstructions. It can conform to any space without leaving gaps or voids. This ensures a continuous and effective insulation layer.
It maximizes energy efficiency and thermal comfort in the home. Blown in insulation can also be used on existing finished surfaces.
Types of Materials Used
Cellulose, fiberglass, and mineral wool are the main types of blown in insulation. Each has unique properties and performance characteristics. These differences make them suitable for various applications and requirements.
Cellulose insulation, particularly Nu-Wool, is often considered the best choice for blow-in insulation. It’s praised for its safety features, including fire retardancy and anti-pest capabilities.
Fiberglass and mineral wool blow-in insulation may pose health concerns if not handled properly. They can release microscopic dust particles that are harmful if inhaled.
| Insulation Type | Key Features | Recommended Use |
|---|---|---|
| Cellulose (Nu-Wool) | Fire-resistant, made from recycled materials, safe installation | Best choice for blow-in insulation |
| Mineral Wool | Loose-fill, made from recycled materials, can be sprayed | Suitable for open walls or wall cavities |
| Fiberglass | Available in blow-in variety, requires special handling | Suitable for attics, walls, and crawl spaces |
The thickness and R-value of blow-in insulation are crucial for optimal energy efficiency. Experienced insulation contractors like Valley Insulation can provide expert guidance. They help homeowners achieve desired thermal comfort and cost savings.
The Importance of Proper Attic Insulation
Attic insulation is vital for home comfort and energy efficiency. It prevents heat transfer between your home’s interior and the outdoors. In winter, it keeps warm air in, while in summer, it keeps hot air out.
The EPA says good insulation can cut energy use by 40% in average homes. This leads to big savings on heating and cooling bills. Proper attic insulation can reduce these costs by 10-15%.
Different attic insulation materials offer various benefits. Fiberglass is cheap and common. Cellulose, foam board, and mineral wool provide different levels of thermal and fire resistance. Insulation effectiveness is measured by R-Value, which varies by region.
Good attic insulation improves energy efficiency and home comfort. It prevents water vapor damage and slows attic heat buildup. It also protects roofing shingles from swelling and cracking. Plus, it may increase your home’s resale value.
NAIMA reports that 90% of US homes are under-insulated. By fixing this, homeowners can save energy and money. They’ll also enjoy better indoor comfort and a more efficient home.

Insulation Maintenance and Replacement
Keeping your blown-in insulation in top shape is key for home energy efficiency. It can last decades but may need replacement if wet, compressed, or your energy bills spike. Regular checks and quick fixes help maintain insulation performance.
Being proactive with insulation care maximizes the benefits of this home upgrade. It ensures continued heat transfer resistance and energy savings.
Insulation Lifespan
Different insulation types have varying lifespans. Blown-in fiberglass insulation can last up to 100 years if undamaged. Cellulose insulation typically lasts 20 to 30 years.
Spray foam insulation can endure for a century or more. Fiberglass batts may start falling off after 15 to 20 years.
Signs of Insulation Deterioration
- Drafts and temperature inconsistencies throughout your home
- Noticeable increase in your energy bills
- Visible damage or deterioration of the insulation material
Importance of Timely Replacement
Poor insulation can lead to higher energy costs and uneven room temperatures. It may also affect indoor air quality, causing respiratory issues and discomfort.
Regular attic insulation upkeep can boost your home’s energy efficiency and comfort. It also improves the overall indoor environment.
“Insulation upgrades such as blown insulation in the attic are typically completed in a single day, providing long-term energy-saving benefits.”
Stay on top of insulation care to keep your home energy-efficient and comfy. This approach ensures an eco-friendly living space for years to come.
Sealing and Insulating Rim/Band Joists
Proper attic insulation is vital, but rim or band joists need attention too. These boards cap floor joists and form the floor assembly’s outer box. Sealing and insulating rim/band joists can boost your home’s energy efficiency.
The International Residential Code sets minimum rim joist insulation requirements. R-13 is required for climate zones 1-4, while R-20 is needed for zones 5-8. Fiberglass batts were traditionally used but can cause moisture issues in colder climates.
Rigid foam insulation is preferred for band joist insulation. It prevents air leaks and offers higher insulation values. For climate zones 6 and colder, closed-cell spray foam is recommended.
- Install at least 3 to 4 inches of rigid foam or a combination of rigid foam and fiberglass insulation for rim joists in colder climate zones.
- Two-component spray foam kits for insulating rim joists can cost between $300 to $400 for a 200-bd.-ft. kit, with an R-value of about R-6.5 per inch.
- Narrow gaps between rim joists and parallel joists, around 2 to 3 inches wide, are best insulated using spray foam due to the difficulty of installing rigid foam in such tight spaces.
Consider insulation requirements for cantilevered joists and band joists too. Properly sealing these areas can enhance your home’s energy efficiency. You’ll enjoy improved comfort and lower energy bills.
Spray Foam Options for Insulation
Spray foam insulation is a powerful alternative to blown-in insulation. It comes in open-cell and closed-cell types. Both offer excellent air sealing and thermal performance.
Open-cell foam is light and flexible. Closed-cell foam is denser with a higher R-value. These foams can insulate attics, walls, and other areas.
They improve energy efficiency and home comfort. Spray foam is versatile for various insulation needs.
Spray foam insulation costs $1.50 to $3.50 per square foot. The price depends on thickness and foam type. It’s pricier than blown-in cellulose insulation, which costs $0.75 to $1.50 per square foot.
Installing spray foam insulation takes time. It may need extra safety measures due to chemicals. However, it effectively seals air leaks.
This prevents insect, mold, and water damage in attics. Spray foam also has a higher R-value than other insulations. It offers better thermal performance and energy efficiency.
Spray foam costs more upfront but provides long-term benefits. It can save energy and enhance comfort. Homeowners should compare blown-in and spray foam insulation options carefully.
Consider your insulation needs, home, and budget. This will help you make the best choice.
| Insulation Type | Cost per Sq. Ft. | R-Value | Environmental Impact |
|---|---|---|---|
| Open-cell Spray Foam | $1.50 – $3.00 | 3.5 – 4.5 | Moderate |
| Closed-cell Spray Foam | $2.50 – $3.50 | 6.0 – 7.0 | High |
| Blown-in Cellulose | $0.75 – $1.50 | 3.2 – 3.8 | Low |
