R Value Of Tilt Up Concrete Wall

But like all concrete systems tilt up offers high thermal mass and airtight construction.

R value of tilt up concrete wall.

The r value of an uninsulated 8 inch thick basement wall built using normal weight concrete is 1 35 based on data from the 1993 american society of heating refrigeration and air conditioning engineers handbook. Astm c1363 effective r value testing typical physical properties wall assembly description eff. 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 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.

Walls can range from r values of about 2 for uninsulated panels up to about 32 for walls containing thicker layers of insulation. As we said before the r value measures the thermal resistance of a material. 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. Tilt up eliminates the transportation costs associated with masonry blocks and precast panels.

Tilt up walls construct quicker and require fewer skilled workers than masonry walls. By doubling the thickness of the wall to 16 inches the r value only increases by 0 50. R value drywall steel framing 1 quik therm concrete wall 9 8 drywall steel framing 2 quik therm concrete wall 14 3. 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.
