By doubling the thickness of the wall to 16 inches the r value only increases by 0 50.
Tilt up concrete wall r value.
However insulation can be added easily to any tilt up panel.
Astm c1363 effective r value testing typical physical properties wall assembly description eff.
As building codes require greater energy efficiency the thickness of insulation increases.
The 3 most common insulation methods for tilt up concrete construction.
What s the r value of a tilt up concrete wall the simple answer to the question is solid tilt up concrete panels have very little r value 0 08per inch.
The standard r value of ready mix concrete used in the tilt up industry including the air film is 1 49 for an 8 inch wall panel.
Walls can range from r values of about 2 for uninsulated panels up to about 32 for walls containing thicker layers of insulation.
In fact concrete allows energy to flow through it roughly 60x faster than insulation.
You will notice in the findings shown in the isothermal analysis that the thermomass wall panel has a material r value of r 11 49.
R value drywall steel framing 1 quik therm concrete wall 9 8 drywall steel framing 2 quik therm concrete wall 14 3.
The steady state thermal analysis shows the total isothermal r value for the wall with the ability to factor in thermal breaks such as metal ties or solid concrete sections.
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.
However since it s easy to add insulation to any tilt up panel this number can rise substantially.
