A Guide To Insulation For Cleveland Homes

Posted by Paul Wadsworth on Mon, Nov 12, 2012 @ 02:42 PM

A guide to insulation typically includes a great deal of information about its composition, resistance factor and installation in your home. But the fundamental fact to remember is that insulation works by slowing the natural tendency of heat to flow from a warmer area into a colder area.

cleveland insulation tipsIn summer, heat energy tends to move toward the cooler zone inside your home. During winter, heat tends to escape toward the outdoors. Insulation in the attic and walls of your home contains millions of tiny pockets of air that slow down heat transfer. Installed in the right place and in the right amount, insulation can save you up to 20 percent on your home’s energy costs.

How insulation is rated

Insulation is assigned an R-rating (“R” stands for resistance) to represent its relative properties to resist heat transfer- the higher R-value rating, the more resistance to heat flow. A recommendation for R-18 means fiberglass insulation with an R-rating of 3.1 per inch should be installed to a depth of at least six inches.

Types of insulation

Fiberglass batts are a common variety of home insulation. Rolled up like large blankets, and cut to fit between ceiling joists in the attic, fiberglass insulation resembles cotton candy. Fiberglass batts have a standard R-rating of 3.1 per inch.

Cellulose insulation is a loose fill product composed of pulverized bits of paper and fabric, cellulose insulation is R-rated at 3.8 per inch.

Where to install

The attic and walls are the prime location for adding extra insulation to a home. Attic insulation is the most easily accessible and additional insulation can be added on top of the existing layer. Upgrading wall insulation requires cutting small access holes.

How much?

The Department of Energy sets standards for residential insulation according to the climate zone of the residence.

In Cleveland, the DOE recommends up to R-60 in the attic and R-15 inside walls. This translates to 20 inches of fiberglass or 15 inches of cellulose in the attic and five inches of fiberglass or four inches of cellulose inside walls.
