The first common mistake when ordering EPS Cement Sandwich Wall Panel is choosing the cheapest product without checking its fire rating. Many low-quality EPS Cement Sandwich Wall Panel products on the market use cheap non-fire-retardant EPS foam, which will not pass local building fire codes. Always ask the supplier to provide an official third-party fire test report before you place any bulk order for EPS Cement Sandwich Wall Panel.

The second mistake is ordering the wrong panel thickness for your use case. Many new builders buy 50mm EPS Cement Sandwich Wall Panel for exterior walls, but this thin panel does not have enough structural strength and insulation performance for outdoor use. Always use 100mm or thicker EPS Cement Sandwich Wall Panel for exterior walls, and only use 50mm panels for non-load-bearing interior partitions.

Third, forgetting to calculate the 3mm expansion gap between panels when calculating total quantity. If you order exactly the total area of your walls, you will end up 2-3% short of panels, because you did not leave space for the expansion gaps between each EPS Cement Sandwich Wall Panel. Always add 3-5% extra panels to your order to cover cutting waste and expansion gaps.

Fourth, not confirming the delivery date clearly in the contract. Many small manufacturers of EPS Cement Sandwich Wall Panel have long production lead times, and they may delay your delivery for weeks during peak season. A clear written delivery date will protect you from unexpected construction delays.

Fifth, ignoring the supplier’s after-sales service. A reliable EPS Cement Sandwich Wall Panel supplier will provide free installation guidance and on-site technical support, while bad suppliers will disappear completely after you pay. Always check the supplier’s past customer reviews before you place your order.

Sixth, ordering panels with wrong height that do not fit your floor. If you order standard 2.4m EPS Cement Sandwich Wall Panel for a 2.7m floor height, you will have to waste a lot of time splicing panels on site. Customize the panel height to exactly match your floor height to save huge amounts of installation time.

Seventh, not checking the panel surface for damage before you sign for delivery. A small number of EPS Cement Sandwich Wall Panel may get chipped during transportation. If you do not check and report the damage immediately, the supplier will not replace the broken panels for free.
