Staircases provide a path of travel between floors in all types of construction. Wood stairs include several components that create horizontal steps. Components include the tread, riser, nosing, and stringer. Straight stairs are the most common, although stairs can also be round, angled, or turn back. Railings are utilized along the path of travel to ensure an individuals safety. A balustrade is the system of railings, balusters and newels that anchor a handrail at both the top and bottom of a staircase. Wood stairs and railings are often stained, but can also be painted.

Wood paneling is a shop fabricated, custom finish material used on horizontal surfaces. Veneer, flitches and laminates are used to provide a decorative panel surface over particleboard, fiberboard, waferboard or a solid lumber core.

Architectural woodwork includes shop-fabricated casework, paneling, stairs, railings, ornamental woodwork, trim, frames, screens, and shutters. Products may be solid wood, laminated, veneered, or simulated wood fabrication. Different from ready-made millwork, architectural woodwork is made to order from specifications or a custom design that requires a traditional or unique interior finish style.

Board paneling is a board product that is applied as a wall finish in a variety of interior spaces. During antiquity, board paneling was used in European castles to insulate the room from cold stone walls. It has also been used to cover the lower portion of drywall affected by moisture from rising dampness. Today board paneling is a decorative product, produced from a variety of wood species.

Prefinished paneling is a decorative sheet product that is applied as a wall finish. Used in a variety of interior spaces, it may be installed as a wainscot or as a full height wall covering. During the 1960's and 1970's, embossed paneling was popular. Today's prefinished paneling features more modern and contemporary designs. Paneling is manufactured from different types of engineered woods, to varying levels of quality.

This topic covers information related to the design and construction of wood framed structures. Information includes both methods and materials for the erection, connection, joining, anchoring, and blocking of framing.

Millwork is produced at a mill from lumber. This ready-made, standard pattern material is used by finish carpenters to finish the interior spaces of buildings. Common types of millwork include casing, baseboards, chair rails, and crown moulding among others.

Shop-fabricated wood trusses are manufactured engineered products in which the chords and webs are made from wood and connected with metal connectors. The simplest form of truss has a horizontal bottom chord and top chords that form the shape of a triangle which offers support and stability for a roof and roof loads. More complex truss shapes have angled bottom chords and mutli-angled top chords.

Parallel strand lumber is manufactured from long strands of wood veneer that are laid parallel to one another and adhered. PSLs are commonly installed as columns, beams and headers in concealed wall spaces where significant bending strength is required to support loads from above; however, they can also be attractively installed as as an exposed finish material.

Also known as engineered lumber, shop-fabricated structural wood is manufactured from wood materials or a combination of wood and metal for use in specific structural applications. Shop-fabricated wood is typically used as beams, columns, joists, trusses and other structural members. Types include Laminated Veneer Lumber (LVL), Parallel Strand Lumber (PSL), Wood I-Joists, Metal-Web Wood Joists, Rim Boards and Shop-Fabricated Wood Trusses.

Wood based underlayments are panel or sheet materials that are used between a structural subfloor and a finish floor surface. Also known as overlayment, wood panel materials are commonly used under resilient tile or sheet floors. They can also be used under adhered carpet or other nonstructural flooring as well.

Subflooring is the structural component of a building that provides rigidity to the floor structure, supports live loads, and serves as the surface to which floor finishes can be applied. Wood subflooring is installed in all types of structures, including timber, platform, and balloon framed. It can also be used in special applications such as radiant heat, floating, raised, or sprung floors. Common types of wood subfloor include individual wood boards and wood panels.
