Precast Panel : Performance Issues

Thermal Performance
The amount of insulation placed in the cavity or within the backup wall

Moisture Protection
The most common moisture protection system used with precast concrete wall systems is a barrier system incorporating an adequate joint seal.

Fire Safety
Precast concrete wall systems are not considered to provide any improvement in fire safety over cast-in-place concrete.

Acoustics
A precast concrete wall system and cast-in-place facade will provide similar performance regarding sound transmission from the exterior to the interior of the building. However, distressed and open joints between panels can provide a condition in which sound transmission to the interior may be increased.

Material/Finish Durability ,Maintainability
The most important maintenance item for precast panels is the sealant in joints and protection system, if used. If a sealer or concrete coating has been used for aesthetics or to minimize moisture penetration into the panel, the sealer or coating will require reapplication.
