Tongue & Groove Planks for Soffit

Made of 100% extruded architectural aluminum, the Longboard Tongue & Groove cladding system is built to provide a simply stunning solution for both siding and soffit. Easy to install, non-combustible, and weather resistant, this system complements any exterior building design. Various plank dimensions and designs are available to choose from and there are also optional perforation solutions for vented applications.

Installed using the supplied Longboard Quick Screen Clips, T&G soffit applications can be installed parallel or perpendicular to the buildings overhang and can also be installed onto furring strips or other framing systems where required. This system requires additional component pieces at terminations and penetrations to allow for expansion and contraction. Manufactured in 12ft or 24 foot lengths they are easily fabricated whether in a pre-fab facility or in the field to suit your project’s conditions.
