Uniboard®'s Nexos Exterior Panels are our most innovative panel solution engineered for exterior applications, created using 100% recycled and recovered pre-consumer wood fiber. Our comprehensive knowledge of resin technology has led us to develop an innovative manufacturing process and high-quality components, resulting in a product that offers superior performance for exterior projects.

Nexos Exterior Panels are incredibly easy to work with and can be cut, routed and machined to various specifications. Designed and produced with proprietary technical properties that resist moisture, Nexos is ideal for use outside where the panels are not directly on the ground.

Uniboard Nexos Exterior Panels are available in North American standard sizes and thicknesses with the same quality and uniformity that has become synonymous with Uniboard's standards of excellence.
