Tilt Up Concrete Wall R Value

In fact concrete allows energy to flow through it roughly 60x faster than insulation.

Tilt up concrete wall r value.

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. However insulation can be added easily to any tilt up panel. 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.

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. 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. By doubling the thickness of the wall to 16 inches the r value only increases by 0 50. But like all concrete systems tilt up offers high thermal mass and airtight construction.

However since it s easy to add insulation to any tilt up panel this number can rise substantially. As we said before the r value measures the thermal resistance of a material. The 3 most common insulation methods for tilt up concrete construction. As building codes require greater energy efficiency the thickness of insulation increases.

Walls can range from r values of about 2 for uninsulated panels up to about 32 for walls containing thicker layers of insulation.
