What is different about attic insulation in Arizona

Extreme cooling load makes HVAC sizing, duct location and roof reflectivity the highest-leverage decisions in the state; pool permitting also carries mandatory barrier inspection.

Owner-builder: Owner-builder allowed with an ROC exemption affidavit on an owner-occupied home. Attic Insulation is one of the scopes a homeowner can more realistically permit themselves.

What drives the price

Attic square footage and existing R-value
Blown cellulose or fiberglass versus spray foam
Air sealing of penetrations before insulating
Attic access and headroom
Removal of contaminated existing insulation
