While the EPS Cement Sandwich Panel is extremely easy to install, there are a few simple common mistakes that contractors can make that will reduce the panel’s long-term performance, and avoiding these will ensure your wall project delivers perfect results for decades. The first mistake is not leaving a small proper expansion gap between panels and the floor, ceiling and adjacent structural elements. Even though the panel has very low thermal expansion, leaving a small gap filled with flexible sealant will prevent any minor cracking from temperature changes over time. The second common mistake is using the wrong type of fasteners to attach the panels to the steel frame or wall structure. You should always use corrosion-resistant self-drilling screws designed for cement composite panels, rather than generic ordinary screws that can work loose over time.
Another mistake many new installers make is not properly sealing all the joints between EPS Cement Sandwich Panel units. Applying a continuous, high-quality waterproof sealant along every panel joint before applying the final surface finish will ensure the wall maintains 100% of its moisture resistance and air tightness, preventing any drafts or water leaks from developing later. It is also important to avoid making large irregular cuts on site without the proper dust collection equipment, as cutting the calcium silicate surface can generate fine dust that should be contained for worker safety. When these simple best practices are followed, installing the EPS Cement Sandwich Panel is faster, safer and the resulting walls will maintain their full performance for the entire 50+ year service life of the building.
