Longboard started out with a focus on rear ventilated plank cladding solutions. We received an increased number of requests from our client base to expand our product offerings to also include large format cladding panel systems. As a result, our Product Innovation team developed the Panelboard™ cladding system and it was released to the market in 2021.

The Panelboard system in many respects is identical to the Longboard tongue and groove plank cladding system and use many of the same mounting accessories and component trims. 

The Panelboard system uses a combination of uniquely designed cladding planks and component trims to create the impression of a solid large format panel. The fact that individual planks and components are used gives the designer and installer a lot more flexibility compared to other large format panel systems.
