Temperature Changes & Expansion/Contraction
It is important to remember that ChamClad® materials will expand and contract with regular temperature changes. ChamClad® trims allow for any variance in panel lengths due to expansion/contraction. When placing fasteners in the center of the designated nail slots, always leave a 1/32″ gap between the fastener head and nail flange to allow ChamClad® panels to expand/contract as needed. The below guide provides recommended spacing based on temperature and Panel Length.
