Everything You Need to Know about Attic Insulation

With attic insulation, Tulsa homeowners have often been led to believe they can do it themselves just by tossing some lose cellulose around. Go to the big-box home improvement store, buy some unfaced insulation (the kind without a paper backing) and start throwing it around the attic — as if that gets the job done. Unsurprisingly, many such do-it-yourselfers then turn to professionals when the homeowner experiences unexplained cold spots, a strange downdraft of cool air, or high heating bills. What you really need to know about attic insulation can be summed up in three words: thickness, conditions and application.

Thickness

For the Tulsa major metropolitan area, the federal Energy Star program makes these attic insulation recommendations:

  • In an uninsulated attic, add R30 to R60 insulation
  • Where insulation already exists, save money by adding R25 to R38

These cost-effective measures prevent wasting money on unnecessary insulation (resulting in too much thickness), while ensuring you have sufficiently thick R-value to save money year-round on heating and cooling bills.

Conditions

The Energy Star program can guide you through the steps of proper do-it-yourself insulating. Two questions to ask yourself:

  1. Is my attic large enough for me to comfortably move around in?
  2. Am I in physically good enough shape for this hard work?

If your Tulsa-area home’s attic is cramped, poorly lit or has a low pitch (angle), consider professional installation. Otherwise, consider these additional caveats:

  • If existing insulation is wet, damp, moldy or shows signs of pest invasion, replace it rather than cover it up
  • If your attic has little or no ventilation, solve that issue before insulating
  • If existing rafters show signs of wet or dry rot or insect damage, hire professionals instead

Application

Attic insulation can be blown in or rolled out. It can even be blown in over existing (or added) rolled out insulation. It cannot simply be scattered, and it definitely should not block airflow from the soffit vents at the roof edge. Correct application is as important as thickness.

The best attic insulation Tulsa homeowners can install should reach all areas of the attic, without blocking needed airflow. This means getting into nooks and crannies, which is why many professionals opt for blown-in insulation under carefully controlled conditions.
