Hardboard / Engineered Wood Siding & Trim

HARDBOARD

Hardboard is used in a variety of applications including furniture components, wall paneling, moulded door skins, underlayment and perforated boards.  

Hardboard is a composite panel manufactured primarily from inter-felted ligno-cellulosic fibers consolidated under heat and pressure. Other materials may be added during the manufacturing process to improve certain properties, such as resistance to abrasion and moisture, and to increase strength and durability. 

Hardboard has a uniform thickness, density and appearance and has no grain. It resists marring, scuffing and abrasion, as well as changes in temperature and humidity. Hardboard can be cut, routed, shaped and drilled with standard woodworking tools. In addition, hardboard can be securely glued or fastened with screws, staples or nails. Hardboard panels can be laminated with paper overlays, plastic laminates and veneers.

ENGINEERED WOOD SIDING & TRIM

Engineered Wood Siding and Trim (EWST) are categories of composite panels that have been designed and manufactured to perform in interior and exterior exposure applications with the appearance of traditional wood. These advanced composites can be engineered with enhanced resistance to moisture, dimensional stability and protection against fungal decay and termites. The engineered properties translate into long-lasting durability allowing for decades of service life while maintaining their attractive appearance.　 Today’s engineered wood siding and trim products are highly versatile and come in many forms including sophisticated woodgrains and embossed surfaces.

Product Standards and Certification

The American National Standard for Hardboard Siding (ANSI A135.6), now referred to as the Engineered Wood Siding Standard, covers requirements and methods of testing for exterior durability, dimensions, straightness, squareness, physical properties and surface characteristics. It also includes trade terms and methods of identifying engineered wood siding. Third-party certification to the ANSI Standards is required for many applications of siding panels. Many building code jurisdictions require the physical properties of engineered wood siding to be third-party certified. CPA’s accredited certification program is recognized and approved by building code officials to evaluate siding products for code compliance.
