Endura Linear Direct Mount Ceiling

Made of 100% extruded architectural aluminum, the Longboard Endura tongue & groove plank system is built to provide a simply stunning solution for linear ceilings. Various plank designs are available to choose from and are also offered with optional perforation and Soundtex scrim for acoustical performance applications. Easy to install, non-combustible, VOC free, and corrosion resistant, this system complements any interior building design. 

Longboard® Endura planks are mechanically fastened to conventionally framed ceiling structures as well as approved suspended ceiling structures and are therefore suitable to be used in all seismic categories. Suspension elements can vary from heavy-duty 15/16” T-grid to struts. Manufactured in either 12 foot or 24 foot lengths they are easily fabricated whether in a pre-fab facility or in the field to suit your project’s conditions.

Why choose Endura planks instead of other linear ceiling products?
