R Value Of 10 Poured Concrete Wall

I agree mostly with junio s answer.

R value of 10 poured concrete wall.

A wall s thermal resistance or its r value is its ability to slow the transfer of heat from one side to the other. 1 25 2 nominal 1 1 2 1 88 2x4 3 1 2 4 38 2x6 5 1 2 6 88. Concrete or concrete block. By doubling the thickness of the wall to 16 inches the r value only increases by 0 50.

But concrete is a conductor of thermal energy not an insulator. Block thickness in inches. As we said before the r value measures the thermal resistance of a material. Concrete block walls u values r values.

R value of 8 20cm poured concrete 0 64 r value of 4 10cm brick 0 80 r value of 1 3cm sheetrock 0 45 r value of 1 3cm sheathing 1 31. However too many people confuse insulation properties with thermal mass many icf dealers d. The insulation may be poured directly into walls or emptied into a simply wood or metal hopper which can be slid along the wall to direct the free flowing perlite into cores of cavities thus insulating all voids and air pockets.

Wood frame walls 3 plus r value of the insulation used floors above unheated spaces 2 plus r value of the insulation used. Use the r value table below to help you determine the r value of your wall or ceiling assemblies. For instance if you have a material with an r value of 12 attached to another material with an r value of 3 then both materials combined have an r value of 15. Cedar logs and lumber.

If you had a 20 x 30 6m x 9m basement with concrete or concrete block walls your heat loss could easily be over 1 million btus per day through the walls. To obtain a wall or ceiling assembly r value you must add the r values of the individual components together. 2 x 4 wood stud wall 16 o c r 11 batts 1 2. Therefore technically it has no insulation value.
