If you’re like most homeowners in Las Vegas, you're focused on keeping your home cool in the summer and energy bills under control year-round. One of the most effective upgrades you can make is in your attic. Choosing the right attic insulation type can significantly improve comfort, lower energy costs, and even extend the life of your HVAC system.

But not all insulation is created equal. In this guide, we’ll break down the most common attic insulation types, their pros and cons, and why proper insulation is so important—especially in Southern Nevada’s desert climate.

Why Attic Insulation Matters

Your attic plays a key role in how your home retains or loses heat. Without the right insulation, heat seeps in during summer and escapes in winter, forcing your HVAC system to work harder. That means higher energy bills and more wear and tear on your equipment.

Proper attic insulation:

• Helps regulate indoor temperatures year-round
• Improves overall energy efficiency
• Reduces the workload on your HVAC system
• Adds value to your home
• Enhances comfort in all seasons

Most Common Attic Insulation Types

When it comes to attic insulation types, there are several popular options—each with its own performance benefits, materials, and installation considerations.

1. Blown-In Fiberglass Insulation

Best for: Attics with existing insulation that needs a boost

Blown-in fiberglass is one of the most widely used attic insulation types. It consists of fine glass fibers blown into place, providing excellent coverage—even in hard-to-reach areas.

Pros:

• Quick installation
• Cost-effective
• Resistant to moisture and fire
• Ideal for topping off existing insulation

Cons:

• Can settle over time
• Requires proper ventilation to avoid moisture issues

2. Batt (Roll) Insulation

Best for: Easy-to-access attics with standard joist spacing

Batt insulation comes in pre-cut panels or rolls and is usually made from fiberglass or mineral wool. It’s ideal for unfinished attic floors or between rafters and wall studs.

Pros:

• Easy to install in open spaces
• Budget-friendly
• Available in different thicknesses for R-value customization

Cons:

• Less effective in irregular or tight spaces
• Can leave gaps if not installed carefully

3. Spray Foam Insulation

Best for: Maximum energy efficiency and air sealing

Spray foam expands to fill every gap, crack, and crevice. It’s one of the most effective types of insulation—but also one of the most expensive.

Pros:

• Excellent thermal resistance (high R-value)
• Creates an air and moisture barrier
• Long lifespan

Cons:

• Higher upfront cost
• Professional installation required
• Not always ideal for all attic structures

4. Cellulose Insulation

Best for: Eco-conscious homeowners looking for recycled material options

Made from recycled paper treated for fire resistance, cellulose insulation is blown into place like fiberglass but has a higher density.

Pros:

• Environmentally friendly
• Good at blocking air flow
• Fire-resistant due to chemical treatment

Cons:

• Can absorb moisture
• May settle over time and lose effectiveness

Which Attic Insulation Type Is Right for You?

The best insulation for your attic depends on several factors:

• Your home’s age and construction
• Your budget
• Energy efficiency goals
• Existing insulation conditions
• Accessibility of the attic space

Las Vegas homeowners often choose blown-in fiberglass or batt insulation due to affordability and suitability for the dry desert climate. However, spray foam is gaining popularity for its performance and long-term savings.
