R30 attic insulation levels.

Your attic should have a certain amount of insulation in it and the recommended level of insulation for your attic is dependent on where you live. The table above shows what levels of insulation are cost effective for different climates. R value is a measure of insulation s ability to resist heat flow. Rigid foam boards trap air or another gas to resist conductive heat flow.

Find your zone on the map and then use the chart to determine the level of insulation you need to properly insulate your attic walls floors and crawlspaces. The recommended level for most attics is to insulate to r 38 or about 10 to 14 inches depending on insulation type.

Insulation materials run the gamut from bulky fiber materials such as fiberglass rock and slag wool cellulose and natural fibers to rigid foam boards to sleek foils.

Add insulation to attic. Our attic has between 12 inches and 16 inches of cellulose insulation. Bulky materials resist conductive and to a lesser degree convective heat flow in a building cavity. Achieving greater r values in attics the higher the r value the better the thermal performance of the insulation.

Our house has r19 in the wall so that meets the current requirement and we have r30 in the floor so that s good as well. The table below contains very general averages. Cellulose insulation has an r value of approximately 3 to 3 5 per inch. R value is a measure of insulation s ability to resist heat traveling through it.
