2 x 6 wall rsi 3 52 r 20 nominal or 2 x 4 wall rsi 2 11 r12 nominal. It s also important to realize the value of air sealing in conjunction with insulation. Where batt loose fill insulation is used provide no less than full cavity insulation.

Insulate the garage s ceiling by using the recommended r value for your area as advised by the department of energy s oak ridge laboratory. You can insulate the walls ceiling and door of the garage to the highest r value possible but if you fail to fill those air gaps you ll still be wasting a lot of heat. The exterior framed walls shall be thermally insulated to a minimum nominal insulation value of rsi 2 11 r12. These r values are a sum meaning this should be the total r value once you add up the entire depth of insulation.

For example if you have a type of insulation that has an r value of r 5 per inch of thickness you will need a depth of 6 inches of this insulation installed in your attic to reach r 30 if you live in zones 2 or 3. By using an insulating material you can reduce the transmission of heat or cold. This number is calculated as a function of thickness of the insulator and its physical properties. Exterior walls if your exterior walls are constructed from 2 by 4 inch studs the most insulation that can go into the wall while retaining its r value is r 13 or r 15 as these are both made to fit a cavity.

Garages typically aren t built to be airtight and have lots of air gaps to the outdoors. Thus r value is used to show the energy efficiency of a product. Finally the larger the number the better the thermal insulation of the door.
