Insulated Precast Concrete Wall Panels R Value

Choose from a number of variables such as concrete thickness insulation climate zone building class and the calculator will provide the total r value of the wall or flooring system.

Insulated precast concrete wall panels r value.

These components come together in one simple to install system that can be erected in much less time than traditional building methods. Insulated precast concrete wall panels can be created as a complete system that includes insulation and a moisture barrier as well as an exterior membrane and interior finish. This combination is also completely fire resistant and sound transmission is reduced allowing intrusive noise to be kept at a minimum. Providing an r value greater than what can be expected by the material alone r 11 49 or by which code requires.

Panel panel standard thickness fabrication r value 8 2 5 x 3 x 2 5 r 19 less than 4 stories. Calculators have been created for precast sandwich panels single layer panels and precast flooring and make calculating r values simple. The r value achieved by precast concrete insulated wall panels can vary widely depending on the desired performance of the wall panel increased r values are achieved by increasing the insulation thickness between the two concrete panels r values for insulated wall panels range from r 5 to r 50. When utilizing climate data for perrysburg oh the proposed 3 in exterior concrete 2 in extruded polystyrene insulation 5 in interior concrete thermomass wall panel performs at r 20 64.

The insulation thickness can vary to create the desired thermal insulating property r value for the wall. 10 3 x 4 x 3 r 18 up to r 22 12 3 5 x 5 x 3 5 r 22 up to r 34 panel fabrication is inches of exterior wythe x inches of insulation x inches of interior wythe r value rating for regular sandwich panels. The r value achieved by precast concrete insulated wall panels can vary widely depending on the desired performance of the wall panel. Packed with equal parts performance and value it is an ideal precast panel solution when the additional thermal performance and cost of a sandwich panel is unnecessary.

Every precast wall panel has a thick layer of energy efficient thermal insulation integrally sandwiched between a very durable concrete interior and a unique beautiful exterior finish. Increased r values are achieved by increasing the insulation thickness between the two concrete wythes. In simple terms r values measure the effectiveness of insulation and a higher number represents more effective insulation.
