R Value Of Tilt Up Concrete Wall

Tilt up eliminates the transportation costs associated with masonry blocks and precast panels.

R value of tilt up concrete wall.

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. As we said before the r value measures the thermal resistance of a material. However insulation can be added easily to any tilt up panel. By doubling the thickness of the wall to 16 inches the r value only increases by 0 50.

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. Walls can range from r values of about 2 for uninsulated panels up to about 32 for walls containing thicker layers of insulation. But like all concrete systems tilt up offers high thermal mass and airtight construction.

In fact concrete allows energy to flow through it roughly 60x faster than insulation. Tilt up walls construct quicker and require fewer skilled workers than masonry walls. As building codes require greater energy efficiency the thickness of insulation increases. 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.
