Insulated Precast Concrete Wall Panels R Value
Panel panel standard thickness fabrication r value 8 2 5 x 3 x 2 5 r 19 less than 4 stories.
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. 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 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. 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.
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. These components come together in one simple to install system that can be erected in much less time than traditional building methods. Providing an r value greater than what can be expected by the material alone r 11 49 or by which code requires.
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. 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.
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. 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 benefits of our precast concrete wall panel systems go on and on.
