Attic Insulation
This upgrade delivers one of the highest returns on investment through energy savings and improved comfort—making it one of the smartest improvements you can make for your home or business. Proper attic insulation is essential for dropping the BTU load on your home, carbon foot print, maintaining comfort, reducing energy costs, and improving overall HVAC efficiency. Current International Residential Code (IRC) guidelines recommend minimum R-38, Good R49 Better, and R60 being the Best Rated attic insulation for most homes in Arizona and similar climate zones, though older homes may have lower levels such as R-19 or R-30 or lower.
At Cooley’s Comfort, our technicians can evaluate your existing attic insulation and determine whether it meets current standards and recommendations. If needed, we can add insulation to help bring your home up to today’s efficiency standards.
Fiberglass Blown-In Insulation
Fiberglass blown-in insulation is a widely used thermal and acoustical insulation solution for both residential and commercial applications. It is ideal for open attic spaces and is also commonly used for retrofits in enclosed wall and floor/ceiling assemblies using pneumatic installation.
Benefits of Fiberglass Blown-In Insulation:
- Non-combustible and fire resistant
- Non-corrosive and odor-free
- Does not promote mold, mildew, or fungus growth
- Contains no formaldehyde or asbestos like cellulose
- Does not rot, decay, or absorb moisture
- Designed to last won’t settle or deteriorate over time like cellulose.
- Provides no food source for insects or rodents
- Helps reduce noise, sound transmission and improve indoor comfort
- Provides thermal resistance for steady temperature control
Blown-in fiberglass insulation fills gaps and voids more effectively than traditional batts, helping reduce air loss and improve energy efficiency and comfort levels.
