While most people associate the EPS Cement Sandwich Panel with wall construction, this versatile material is also an excellent option for lightweight insulated roof overlay systems on low slope and flat roof buildings. A properly specified EPS Cement Sandwich Panel installed over an existing roof structure creates a continuous insulated layer that adds much needed thermal performance without adding excessive dead load weight to the underlying roof frame. This is a huge advantage for older buildings whose original roof structure was not engineered to support the heavy weight of thick traditional roof insulation and roofing materials. The rigid cement top facing of the EPS Cement Sandwich Panel creates a strong, durable base that you can apply your final waterproof roofing membrane directly onto, eliminating the need for extra separate sheathing layers. This roof installation process is much faster than traditional roof insulation methods, and it creates a perfectly even, flat surface that makes it much easier for roofing crews to install a fully weathertight waterproof top layer. Many warehouse, industrial, and commercial building projects have successfully used the EPS Cement Sandwich Panel as part of their roof renovation systems to upgrade roof insulation performance without overloading their existing older roof structure.
