Insulated Precast Concrete Wall Panels R Value

The difference between typical panels and insulated sandwich wall panels is that the latter are cast with rigid insulation sandwiched between two layers or wythes of concrete.

Insulated precast concrete wall panels r value.

Calculators have been created for precast sandwich panels single layer panels and precast flooring and make calculating r values simple. 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. 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. Panel panel standard thickness fabrication r value 8 2 5 x 3 x 2 5 r 19 less than 4 stories.

Yes we did enclose a structure the size of 31 football fields with precast concrete wall panels but the bigger story is the flexibility speed of erection and value of tindall s products. 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. 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 insulation thickness can vary to create the desired thermal insulating property r value for the wall.

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. The benefits of our precast concrete wall panel systems go on and on. Increased r values are achieved by increasing the insulation thickness between the two concrete wythes. 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.

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. Still highly capable thermally versacore green delivers r values ranging from a leed friendly r 13 6 in an 8 inch thick panel up to r 20 2 in a 12 inch thick panel.
