Gilbert Insulation: Climate, Market & Cost Drivers
In Gilbert's extreme heat, adequate attic insulation is the single most effective measure for reducing cooling costs. Spray foam applied to the underside of the roof deck creates an unvented conditioned attic — keeping HVAC ducts in conditioned space and preventing the temperature extremes that degrade standard blown-in insulation in intense desert climates. R-38 to R-49 is the appropriate target for attic assemblies in Gilbert.
Gilbert labor rates track near the national average for this type of project.
