Las Vegas enjoys more than 300 sunny days a year, but that desert sunshine can turn second-story bedrooms into saunas. In most two-story homes, heat rises through the living space and collects in the attic. When the attic lacks adequate thermal protection, that stored heat radiates back down through ceilings and air-ducts, driving indoor temperatures up—sometimes 10-15 °F hotter upstairs than downstairs. Poor ventilation, aging fiberglass batts, and gaps around light fixtures all compound the problem.
How Attic Insulation Works
Attic Insulation Las Vegas acts like a thermal lid. Quality loose-fill cellulose or fiberglass blankets trap air inside millions of tiny pockets, slowing the flow of heat. In summer, a well-insulated attic blocks rooftop heat from entering living areas; in winter, it prevents conditioned air from escaping. The Department of Energy recommends an R-value of R-49 for attics in climate zone 5B—exactly where Las Vegas, NV sits. Many Valley homes built before 2000 test at only R-19 to R-30, leaving plenty of room for improvement.
Signs Your Home Needs Attic Insulation Services
- Stubbornly hot upstairs rooms even when the A/C runs nonstop
- High NV Energy bills from May through September
- Cold drafts in winter—heat loss works both ways
- Uneven dust layers indicating air leaks around can lights and vents
- HVAC system short-cycling because the thermostat never reaches set temperature
If two or more of these symptoms look familiar, an attic energy audit should be next on your to-do list.
Types of Insulation We Install
| Material | R-Value per inch | Best For | Key Benefit |
| Blown-in fiberglass | 2.8-3.5 | Existing attics needing top-off | Non-settling, quick install |
| Blown-in cellulose | 3.2-3.8 | Green retrofits | Recycled content, air-sealing fibers |
| Spray foam (open-cell) | 3.6-3.8 | Vaulted ceilings, difficult roofs | Air barrier + insulation in one step |
| Spray foam (closed-cell) | 6.0-6.5 | Flat roofs, metal buildings | Highest R per inch, moisture barrier |
Each home is evaluated for roof pitch, joist depth, duct layout, and budget before recommending the ideal Attic Insulation Services package.
The Installation Process Step by Step
- Free attic inspection—our technicians measure current depth, locate bypasses, and film thermal images.
- Air-seal critical gaps—we foam electrical penetrations, top plates, and chaseways to stop airflow.
- Ensure proper ventilation—baffles are added to keep soffit vents clear and encourage roof deck cooling.
- Blow or spray insulation to the target R-value, verifying depth with rulers every 100 sq ft.
- Post-job quality check—another infrared scan confirms even coverage and identifies any missed spots.
This five-point system means no mess in your living space and a completed job in one day for most Las Vegas attics under 1,500 sq ft.
Energy Savings and Comfort Gains
Homeowners often ask, “Is it worth it in our desert climate?” The answer is yes—especially upstairs. Boosting an attic from R-19 to R-49 can save 15-20 % on annual cooling costs. More importantly, bedroom temperatures drop 8-12 °F during peak August afternoons, making sleep comfortable without cranking the thermostat to 68 °F. Lower HVAC runtime extends equipment life and reduces maintenance bills as well.
Rebates and Local Codes
Southern Nevada residents may qualify for NV Energy’s PowerShift attic insulation rebate when upgrading with a participating contractor. Las Vegas building code now requires R-38 minimum for new construction, so retrofitting older homes to current standards protects resale value. Our team handles paperwork, photos, and submission, ensuring you capture every available incentive.
DIY vs. Professional Attic Insulation Services
Hardware stores rent blowers, but a weekend warrior rarely achieves uniform coverage. Missing just 5 % of attic floor area can slash overall R-value by up to 50 %. Professionals possess commercial-grade equipment, infrared cameras, and safety gear to navigate trusses and recessed cans without tearing existing ductwork. The modest labor investment pays for itself in tighter air-seals and consistent depth.
