Insulated Precast Concrete Wall Panels R Value

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.

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.

The r value achieved by precast concrete insulated wall panels can vary widely depending on the desired performance of the wall panel.

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. Calculators have been created for precast sandwich panels single layer panels and precast flooring and make calculating r values simple. 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. 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.

These components come together in one simple to install system that can be erected in much less time than traditional building methods. In simple terms r values measure the effectiveness of insulation and a higher number represents more effective insulation. Providing an r value greater than what can be expected by the material alone r 11 49 or by which code requires. This combination is also completely fire resistant and sound transmission is reduced allowing intrusive noise to be kept at a minimum.

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. The insulation thickness can vary to create the desired thermal insulating property r value for the wall.
