Autoclaved Aerated Concrete (AAC) block is one of the most popular lightweight wall materials that competes directly with EPS Cement Sandwich Wall Panel in the modern construction market. Many builders only compare the initial per square meter material price, and miss the huge difference in total project cost between the two materials. This full cost breakdown analysis covers every expense item from initial material purchase all the way to 10 year operating cost, to give you a complete objective comparison.
At first glance, the raw material price per square meter of AAC block appears slightly lower than EPS Cement Sandwich Wall Panel. But once you add all the extra required costs for AAC block walls, the total cost difference reverses very quickly. AAC block walls still need to be laid with cement mortar, then covered with a full 20mm thick layer of plaster on both sides, before you can start painting. All of these extra materials and labor add huge extra cost. The total labor cost for installing 1 square meter of AAC block wall plus plaster is more than 3 times higher than the installation labor cost for 1 square meter of EPS Cement Sandwich Wall Panel, as the panel arrives pre finished and ready for direct painting.
When you add up all material and labor costs for a fully finished ready to decorate wall, the total cost of EPS Cement Sandwich Wall Panel is around 20% lower than the total cost of an AAC block wall. On top of that, the EPS Cement Sandwich Wall Panel delivers far better thermal insulation performance, which reduces annual building energy cost by an extra 30% compared to AAC block walls. Over a 10 year period, the total cumulative cost for a building using EPS Cement Sandwich Wall Panel is nearly 35% lower than the same building built with AAC block walls. This full cost breakdown clearly shows that EPS Cement Sandwich Wall Panel delivers far better long term economic value for almost all construction project types.
