How Attic Insulation Benefits Homeowners in Hot Climates

Depending on the climate zone, attic insulation benefits can vary. Essentially, attic insulation resists the transfer of heat between the living quarters of your home and the attic overhead. If your home was built before 1980, it may well be under-insulated by today’s efficiency standards. Upgrading to current U.S. Department Of Energy recommendations will reduce heating and cooling costs by up to 50 percent, depending on climate zone, particularly if installation is preceded by sealing air leaks.

Major attic insulation benefits:

  • Increased Comfort:
    • Reduce outside noise
    • Control inside temps
    • Lower attic heat
  • Save Money:
    • Lower cooling costs significantly
    • Extend life of HVAC equipment

Attic insulation types:

Blown-in fiberglass attic insulation benefitsThere are two main types of insulation used in attics. In a hot climate zone like southern Arizona, for example, we typically recommend blown-in fiberglass and radiant barrier. Blown-in fiberglass insulation provides a dense, effective barrier against heat loss that is also among the greenest insulation options. It provides affordable R-Value per inch and offers low environmental impact and immediate energy savings. Proper installation is a must for blown-in insulation. Special equipment and safety measures are required to ensure long-term performance.

A radiant barrier, such as HeatBloc-Ultra, is applied to the underside of the attic roof deck to significantly reduce the amount of radiant heat entering the structure, thereby reducing cooling requirements and saving you money. Radiant barrier attic insulation benefits homeowners because it stops over 80% of the radiant heat that is trying to enter your attic from the roof. The service life of HVAC equipment like air conditioners and furnaces is extended due to reduced cooling and heating load.

Radiant Barrier attic insulation benefitsHeatBloc-Ultra is an aluminum colored, water- based, low emissivity coating. 80% of the heat gain in a home located in the southern part of the country, during the Summer, is from radiant heat. When applied to building materials such as plywood, plasterboard or OSB, HeatBloc-Ultra will have a dramatic effect on the performance of the home and will stop over 80% of the radiant heat that is trying to enter your attic from the roof.
