Expert Attic Insulation Services in Las Vegas
In Las Vegas's extreme desert climate, where summer temperatures regularly exceed 110°F, proper attic insulation is your first line of defense against skyrocketing energy bills. The Cooling Company specializes in professional attic insulation installation that can reduce your cooling costs by 20-30% while improving indoor comfort year-round.
Why Attic Insulation Matters in Las Vegas
Your attic can reach temperatures of 150-160°F during Las Vegas summers. Without adequate insulation, this extreme heat radiates directly into your living spaces, forcing your air conditioner to work overtime. Proper attic insulation creates a thermal barrier that keeps heat out in summer and warmth in during winter.
Benefits of Proper Attic Insulation:
- 20-30% reduction in cooling and heating costs
- More consistent indoor temperatures throughout your home
- Reduced strain on your HVAC system (extending its lifespan)
- Improved indoor air quality by sealing out dust and allergens
- Qualify for NV Energy rebates and incentives
- Increased home value and appeal to buyers
Types of Attic Insulation We Install
Blown-In Fiberglass Insulation
Blown-in fiberglass is the most popular choice for Las Vegas attics. Loose fiberglass fibers are pneumatically blown into your attic, filling every gap and creating a seamless thermal barrier.
Advantages:
- Excellent coverage around obstacles (joists, wiring, ducts)
- Cost-effective for most applications
- Non-combustible and fire-resistant
- Doesn't settle as much as cellulose
- Ideal for topping up existing insulation
Cost: $1,500-$3,500 for typical 1,500-2,000 sq ft home
Blown-In Cellulose Insulation
Made from recycled paper products treated with fire retardants, cellulose insulation offers excellent R-value per inch and superior air sealing properties.
Advantages:
- Higher R-value per inch than fiberglass
- Better air infiltration control
- Eco-friendly (80% recycled content)
- Excellent sound dampening
- Naturally resistant to pests and mold
Cost: $1,800-$4,000 for typical home
Batt Insulation (Fiberglass or Mineral Wool)
Pre-cut insulation panels designed to fit between standard attic joist spacing. Best for new construction or attics with few obstacles.
Advantages:
- Lower labor costs for simple installations
- Easy to see coverage and R-value
- No special equipment required
- Good for DIY-savvy homeowners
- Available in faced (vapor barrier) or unfaced
Cost: $1,200-$2,500 for typical home (materials only: $300-$800)
Spray Foam Insulation
The premium option—spray polyurethane foam expands to fill every crack and crevice, creating an airtight seal with the highest R-value per inch.
Advantages:
- Highest R-value per inch (R-6 to R-7)
- Complete air sealing (stops infiltration)
- Structural strength (adds rigidity to roof)
- Moisture barrier properties
- Lasts 80+ years without settling
Cost: $3,500-$7,000 for typical home
Recommended R-Values for Las Vegas Attics
The U.S. Department of Energy recommends R-38 to R-49 for attics in Las Vegas (Climate Zone 3). However, the extreme desert heat means higher R-values provide better returns on investment.
R-Value Guidelines:
| Insulation Type | Depth for R-38 | Depth for R-49 | Recommended |
|---|---|---|---|
| Blown-In Fiberglass | 14-16 inches | 18-20 inches | R-49 |
| Blown-In Cellulose | 11-13 inches | 14-16 inches | R-49 |
| Fiberglass Batts | 12-13 inches | 16-17 inches | R-38-R-49 |
| Spray Foam | 6-7 inches | 8-9 inches | R-49+ |
Our Recommendation: For Las Vegas's extreme climate, we recommend targeting R-49 or higher in attics. The incremental cost difference is minimal, and the energy savings are substantial.

Attic Insulation FAQ
How much can I save with proper attic insulation?
Most Las Vegas homeowners save 20-30% on cooling and heating costs after upgrading to R-49 insulation. For a home with $300/month summer electric bills, that's $60-$90/month or $720-$1,080 annually. With installation costs of $2,000-$4,000, payback typically occurs in 3-5 years, with continued savings for decades.
What R-value do I need in Las Vegas?
The Department of Energy recommends R-38 to R-49 for Las Vegas attics (Climate Zone 3). However, due to extreme summer heat (attics can reach 160°F), we recommend targeting R-49 or higher for optimal energy savings. Higher R-values provide better returns on investment in our climate.
Should I remove old insulation before adding new?
Not always. If existing insulation is clean, dry, and pest-free, we can often add new insulation on top to reach target R-value. However, removal is necessary if old insulation is: water-damaged, contaminated with mold or pests, compressed and ineffective, or if air sealing work requires access to attic floor.
Can I install attic insulation myself?
While DIY installation is possible with batt insulation, we strongly recommend professional installation for several reasons: rental equipment costs make professional installation competitive; proper air sealing requires expertise and specialized materials; ventilation requirements are critical in Las Vegas heat; achieving uniform coverage and target R-value is challenging; rebate programs require professional installation and documentation.
How long does attic insulation last?
Lifespan varies by material: Fiberglass (blown-in or batt): 80-100 years, Cellulose: 20-30 years, Spray foam: 80+ years. However, effectiveness can diminish due to: compression from storage or foot traffic, pest damage or contamination, moisture infiltration, air leakage bypasses. We recommend professional inspection every 10-15 years.
Will insulation help with summer cooling?
Absolutely! In fact, attic insulation provides greater benefits for cooling than heating in Las Vegas. Without proper insulation, heat from your 150-160°F attic radiates down into living spaces, forcing your AC to run constantly. R-49 insulation creates a thermal barrier that keeps this extreme heat out, reducing cooling loads by 20-30% and improving comfort.
Do I need more attic ventilation with new insulation?
Proper attic ventilation is critical in Las Vegas's extreme heat. The general rule is 1 square foot of net free ventilation area per 150 square feet of attic space. Common ventilation includes: soffit vents (intake air), ridge vents or turbine vents (exhaust hot air), gable vents (cross-ventilation). We'll assess your ventilation during inspection and recommend improvements if needed.
What about radiant barriers?
Radiant barriers (reflective foil barriers) can complement insulation in Las Vegas attics by reflecting radiant heat away before it warms the insulation. They're most effective when: installed on the underside of roof decking, combined with adequate insulation (R-38+), proper ventilation is maintained, ducts are NOT in the attic. Radiant barriers add $0.50-$1.00 per square foot but can reduce attic temperatures by 20-30°F.
Can insulation help with indoor air quality?
Yes! Proper attic insulation and air sealing improve indoor air quality by: preventing outdoor dust and allergens from infiltrating your home, reducing air leakage that brings in pollen and pollutants, maintaining consistent temperatures and humidity levels, allowing your HVAC system to filter air more effectively. Combined with proper indoor air quality solutions, insulation creates a cleaner, healthier home environment.
What preparation do I need to do before installation?
Minimal preparation is required on your part. We recommend: removing stored items from attic access areas, providing clear path to attic access, securing pets during installation day, planning to be home for initial inspection and final walkthrough. Our crew handles all attic preparation, installation, and cleanup. We'll protect your home with drop cloths and ensure no mess is left behind.
