Many builders want to know the long-term durability of EPS cement sandwich wall panel, and real field test data from projects built 30 years ago gives a very reassuring answer. After decades of exposure to sun, rain, temperature changes and normal use, most of these panels still maintain more than 90% of their original structural strength.

The cement outer layer of the EPS cement sandwich wall panel forms a strong protective shell that prevents water, oxygen and ultraviolet rays from reaching the internal EPS core. This stable composite structure does not have the aging problems that trouble many pure plastic or foam wall materials.

As long as you follow the basic installation and joint sealing guidelines, a high-quality EPS cement sandwich wall panel can easily last more than 50 years in normal building environments. This long service life makes it a highly reliable investment for any construction project.
