With more and more manufacturers entering the market, the quality of EPS Cement Sandwich Panel products varies a lot, and choosing a qualified high quality product is extremely important to make sure your building project can get all the performance benefits. First of all, you should check the basic material specification of the product. The raw materials should be made of high quality cement, qualified fly ash and standard density EPS beads, not recycled waste foam materials. Second, ask the supplier to provide official third party test reports that prove the product’s compressive strength, sound insulation value, fire rating and thermal insulation performance. A reliable qualified EPS Cement Sandwich Panel should have compressive strength higher than 3.5 MPa, sound insulation over 45 dB, and service life over 70 years. Third, check the surface quality of the panel. The high quality product should have a smooth flat cement surface, no cracks, no warping deformation, and the thickness of the two outer cement layers should be even and consistent. Fourth, confirm that the supplier can provide complete supporting installation accessories and professional installation guidance service. Even the best quality EPS Cement Sandwich Panel will not perform well if it is installed incorrectly by unskilled workers. You should also avoid choosing products with extremely low prices that are far below the normal market level. Those cheap products usually use very low density EPS core and very thin cement layers, which have poor strength and durability, and may bring hidden safety risks to your building. Take your time to verify the product quality before you make the purchase decision, this will help you avoid a lot of unnecessary troubles in the future.
