Choose your formwork panel
All ILPA formwork panels share the same origin: certified wood, industrial quality control and over 45 years of experience. They differ in core, surface coating and edge protection – and therefore in weight, service life and cost per pour. This table compares them side by side to help you pick the right panel for your formwork system, your rental fleet or your job site.
