Durable, eco-friendly
The modulus of elasticity and high tensile and flexural strength of PaperStone® assures superior resistance and exceptional pull-out strength around mounting fasteners. PaperStone’s composite panels are not affected by water and are not susceptible to deterioration by weather, mold or rot. PaperStone® panels can be easily cut and drilled on the job site using carbide-tipped woodworking tools.

Fire protection
PaperStone® sustainable cladding offers maximum safety and protection against fire. It is the product of choice in cladding applications requiring high fire resistance. PaperStone® will not melt, liquefy or explode. In a fire, it retains its stability for an extended time. It has a UL Class A rating for both flame spread and smoke developed index in accordance with ASTM E84 testing.

PaperStone® Panels are Available in Sizes to Meet Specific Application Requirements
Maximum panel size is 5 x 12 feet. PaperStone® panels are available in a variety of thicknesses to meet specific application requirements. Panels can be cut to size and drilled on the jobsite. When cut, an edge-sealer should be applied before installing.

Maintenance and Care
PaperStone® panels may be cleaned with a soft cloth and mild cleaning agents such as White Mountain ‘Jobsite’ Cleaner or Dawn detergent and hot water. Avoid use of harsh abrasives or ammonia cleaners.
