What is Home Insulation?
Home insulation is a big deal for keeping your home warm and saving energy. I’ve seen how it can turn a cold house into a warm one. It works by slowing down heat flow between inside and outside.
Did you know most homes in the U.S. don’t have enough insulation? It’s a shocking fact! Let’s explore how insulation can make your home better.
Insulation’s quality is measured by its R-value. The higher the R-value, the better it works. For example, R-38 insulation needs 12 inches of thickness. If you only have 5 inches, you need 7 more inches to meet the standard.
There are many types of insulation:
- Blown-in insulation: Great for hard-to-reach areas
- Batt insulation: Easy to install and less prone to settling
- Foam board: High R-values for various areas in your home
- Spray foam: Offers excellent air sealing properties
Let’s look at some common insulation materials:
| Insulation Type | R-value per inch | Recycled Content |
|---|---|---|
| Blown-in Fiberglass | 2.2 – 2.7 | 30% |
| Blown-in Cellulose | 3.2 – 3.8 | 75-85% |
| Standard Fiberglass Batts | 2.9 – 3.8 | 20-30% |
| High-Performance Fiberglass Batts | 3.7 – 4.3 | 20-30% |
Picking the right insulation can save a lot of energy and make your home more comfortable. It’s important to think about your needs and talk to a pro to find the best insulation for your home.

| Batt | R-13 to R-21 | DIY possible | Standard wall cavities |
Both types are good for home insulation. Your choice depends on your home, budget, and whether you’re doing it yourself or hiring experts. Good insulation makes your home comfortable and energy-efficient.
Comparing Blown-In Insulation vs Batts
Choosing insulation for your home is important. You should know the differences between blown-in insulation and batts. Each has its own benefits, and the right choice depends on your needs.
Core Differences
Blown-in insulation is great for filling odd spaces, like attics and crawl spaces. It’s fast to install and fills small gaps well. Batt insulation, pre-cut and uniform, fits standard spaces easily but needs cutting for odd shapes.
R-Values and Thermal Performance
R-values show how well insulation keeps heat in. Fiberglass batts have 2.9 to 4.3 per inch. Blown-in fiberglass ranges from 2.2 to 3.8. Cellulose blown-in is 3.2 to 3.8 per inch. Blown-in insulation often covers more space, which can make your home more energy-efficient.
Durability and Longevity
Batt insulation keeps its shape longer, needing less upkeep. Blown-in insulation might settle, so it might need topping up sometimes. Both can be affected by moisture, but cellulose settles more when wet. The choice between blown-in and batts for your attic or crawl space depends on your home’s conditions.
| Feature | Blown-In Insulation | Batt Insulation |
|---|---|---|
| Installation Speed | Faster | Slower |
| Coverage | Better for irregular spaces | Better for standard spaces |
| R-Value Range | 2.2-3.8 per inch | 2.9-4.3 per inch |
| Settling | May settle over time | Maintains shape |
| Best For | Attics, crawl spaces | Walls, between joists |
Cost Analysis: Installation and Long-Term Value
I’ve looked into the costs of attics insulation, and it’s quite interesting. We’ll explore the upfront costs and long-term savings of various insulation types.
Initial Installation Costs
Fiberglass batts are the cheapest option, costing $0.85 to $1.25 per square foot. For a 2000 square foot attic, you’ll spend about $1,700 for R-30 insulation. Blown-in insulation, which needs a special machine, is more expensive at first.
Fiberglass costs $1.25 to $1.75 per square foot, while cellulose is $1.35 to $1.85. This means you’ll pay $2,500 to $3,000 for the same area.
Long-Term Value and Energy Savings
The U.S. Department of Energy says you can save up to 15% on heating and cooling with good attic insulation. Upgrading insulation can help you get back the cost when selling your home. One homeowner spent $1,900 on blown-in insulation for 950 square feet, doubling their R-value from 26 to 52.

Calculating Long-Term Savings
To find your savings, think about the initial cost, maintenance, and lower energy bills. A homeowner in the Midwest spent $1,900 on insulation and noticed a big difference in temperature. Another saw a 10% drop in their power bill after a $650 insulation upgrade.
Remember, going beyond the best insulation might not save you money. The best choice is to upgrade from poor to good insulation for the best return on investment.
Environmental Impact and Sustainability
I always look for eco friendly insulation options. Let’s see how blown-in and batt insulations compare in terms of sustainability.
Recycled Content in Blown-In vs Batt Insulation
Blown-in insulation often wins in terms of recycled content. Cellulose insulation, made from recycled newspaper, has 85% recycled materials. Loose fill fiberglass also has a lot of recycled glass, up to 30%.
Batt insulation has less recycled content. But, rock wool batts can have up to 85% recycled materials.
Carbon Footprint of Each Type
The carbon footprint of insulation types differs. Cellulose insulation has a lower environmental impact because of its high recycled content. Fiberglass production uses more energy, but its long life can make up for it.
Here’s a comparison of R-values per inch:
| Insulation Type | R-Value per Inch | Recycled Content |
|---|---|---|
| Cellulose (Blown-in) | 3.2 – 3.8 | ~85% |
| Fiberglass (Blown-in) | 2.2 – 4.3 | 20-30% |
| Rock Wool (Batt) | 3.0 – 3.3 | Up to 85% |
It’s important to think about both the making process and long-term energy savings. This helps us understand the environmental impact of insulation choices.
Installation Challenges and Considerations
Insulating your home comes with many things to think about. Both blown-in and batt insulation face unique challenges. Let’s explore the key factors to consider.
Moisture Resistance and Vapor Barriers
Moisture is a big problem for insulation. Blown-in fiberglass can hold water for a long time, which isn’t good. Batt insulation gets even worse when it’s wet. That’s why vapor barriers are key. They keep moisture out and your insulation dry and effective.
Ventilation and Mold Prevention
Good airflow is essential. Without it, you risk mold growth. Mold thrives in damp, stuffy places. To prevent it, your insulation setup must allow for enough air movement. This applies to both blown-in and batt types.
Installation Process for Both Types
Installing insulation isn’t always easy. Blown-in insulation needs special equipment and a pro for proper installation. Batts can be a DIY job, but fitting them in odd spaces can be tricky. Spray foam insulation is harder to install but offers a tight seal that’s hard to beat.
| Insulation Type | Installation Difficulty | Best For |
|---|---|---|
| Blown-In | Requires special equipment | Attics, hard-to-reach areas |
| Batt | Can be DIY | Walls, regular spaces |
| Spray Foam | Professional installation needed | Air sealing, high R-value areas |
Each type has its own benefits. Blown-in is best for attics, while batts are good for walls. Also, some types, like cellulose, can act as a fire retardant. Choose based on your specific needs and budget.
Professional Installation vs DIY
I’m thinking about insulating my home and I’m torn between hiring a pro or doing it myself. Insulating areas like the attic floor or crawl spaces is a big decision.
Required Tools and Equipment for DIY
For DIY insulation, I’ll need some basic tools. For batt insulation, I’ll use a utility knife, tape measure, and staple gun. But for blown-in insulation, I’ll need a blowing machine, which I don’t have.
Skill Level and Safety Considerations for Installation
Safety is key when insulating by DIY. I’ll need protective gear like gloves, goggles, and a mask. Working in tight spaces, like attics, can be hard, and there’s a risk of asbestos in old insulation.

DIY can save money upfront, but professional installation ensures it’s done right. Pros handle tricky areas and follow building codes. They’re also ready for unexpected problems like mold or electrical wiring. For complex jobs or spray foam insulation, hiring a pro is safer and more effective.
Conclusion
I’ve looked into the main differences between blown in insulation and batts. Both have their good points. Blown-in insulation covers more space well, fitting into odd shapes easily. It also has a slightly higher R-value, which means it keeps heat better.
But, batt insulation has its own benefits. It’s cheaper to start with and simpler to put in, which is great for those who like to DIY. It also doesn’t settle as much over time, unlike blown-in. Both can last 15-20 years if taken care of right, but need different upkeep.
When deciding between batt and blown insulation, think about your home’s needs. Blown-in insulation fights pests better and is greener, using recycled stuff. Yet, batts are simpler and cheaper. Remember, a lot of heat escapes through the roof, so good insulation is key. Maybe using both types is the best way to keep your home cozy and energy-efficient.
