Stonewood is a beautiful, solid, strong material that is ideal for either horizontal or vertical surfaces where strength and appearance are both important.

Stonewood is used for decorative interior and exterior wall panels, rain screens, lockers, laboratory and office furniture, medical equipment carts, x-ray tables, work surfaces, fixtures, ergonomic keyboard platforms, tablet arms, cutting boards and any application requiring strength, rigidity, durability, moisture resistance and decorative appeal. Stonewood is also chemical resistant, having passed SEFA chemical testing requirements.

Its high strength to weight ratio allows Stonewood to be used in place of plywood, particleboard, fiberboard or other wood products. Stonewood panels maintain their dimensions and can be fabricated with standard wood-working tools. The material can be attached with screws or adhesives and is water and mold resistant. Stonewood can be sanded on both sides to improve adhesion in composite applications.

Building Material

Stonewood is available as a Class A or Class B fire resistant wall cladding material. Stonewood Exterior also features UV resistance.  Architects and designers are utilizing these highly customizable phenolic wall panels to create truly original building designs. Stonewood phenolic building cladding and rain screens offer a brand new pallete to the creative architect. Interior designers and decorators are also discovering new possibilities utilizing Stonewood phenolic wall panels.  Fiberesin has created a dedicated website describing the use of Stonewood in construction.  We encourage you to visit


Stonewood is 100% made in the USA. Fiberesin’s plant where Stonewood is made is BIFMA level®; certified. You can read about the comprehensive BIFMA level®; certification process here.

Manufacturing Process

Stonewood is a thermally fused material comprised of multiple sheets of kraft fiber paper. These kraft papers can be provided as FSC®; (Forest Stewardship Council®;) (FSC-C115183) certified material upon request. To produce Stonewood, Fiberesin impregnates the raw core kraft sheets with phenolic resins that are then cured. The treated papers are then hot pressed, fusing the layers into a solid panel. Stonewood does not emit formaldehyde, is resistant to burning, and can support significant weight without breaking.

Self Edging

While traditional edge treatments can be used, Stonewood can be easily fabricated to be self-edging. Minimal sanding and polishing creates an attractive edge that is visually and tactilely pleasing. Stonewood is economical since no additional edge treatment is required.

Colors, Patterns and Woodgrains

Stonewood is available in an endless variety of solid colors, patterns, wood grains, stones, or marbles. It is also available in solid bright white with a white core. Real wood veneers are available as well.  The Stonewood core material is available in Black, Brown, or Bleached.  Click to open a PDF showing the colors and patterns available for Stonewood.

Custom Graphics

In addition to numerous colors and woodgrain options, Fiberesin’s unique custom graphics capabilities makes it possible to fuse any artwork, photograph, original image, or logo directly into the panel surface making it virtually impervious to moisture, abrasion, and stains.

Chemical Resistant

Stonewood is also a chemical resistant material that can be used in laboratory, medical, or education environments where such surface properties are important. Stonewood has passed SEFA 8-PH-2010, Section 8.1 testing for chemical resistance. You can read more about SEFA here.
