We do offer mouldings that are specially formulated for heat bending, but not all cellular PVC trim and mouldings apply. For example, Royal S4S Trimboard is not recommended for bending, but SurEdge and Precision Cut trim can be bent into a reasonable radius.

Cellular PVC is a thermoplastic polymer, which means it becomes pliable or bendable when exposed to certain temperatures, returning to a solid state when cool. Because of its nature, some cellular PVC profiles can be reheated and reformed; however, variations in batches, profile geometry, and density or weight of the profile mean some experimentation will be required to perfect this skill.

For best results, don’t bend any cellular PVC trim greater than 6” wide.  Please see the Royal Installation Handbook for detailed instructions regarding bending PVC.
