Insulated precast concrete wall panels r value.

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. 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. 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. 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.

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. 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. Increased r values are achieved by increasing the insulation thickness between the two concrete wythes. 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.

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. 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.

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.
