R Value Of Tilt Up Concrete Wall

As building codes require greater energy efficiency the thickness of insulation increases.

R value of tilt up concrete wall.

Astm c1363 effective r value testing typical physical properties wall assembly description eff. Walls can range from r values of about 2 for uninsulated panels up to about 32 for walls containing thicker layers of insulation. 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. 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.

Tilt up eliminates the transportation costs associated with masonry blocks and precast panels. By doubling the thickness of the wall to 16 inches the r value only increases by 0 50. In fact concrete allows energy to flow through it roughly 60x faster than insulation. However insulation can be added easily to any tilt up panel.

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 s fast construction means new structures become enclosed sooner which protects workers their tools and other supplies from outside elements. 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. Tilt up walls construct quicker and require fewer skilled workers than masonry walls.
