Rimboard is an integral part of any project that uses engineered wood products as the primary component of the framing system. Rimboard is the product of choice to cover the ends of I-joists designed for the floors of the construction project.

A replacement for the rim joist in conventional framing, the rim board of an engineered wood flooring system provides structural stability and weather protection to wood I-joists. Rimboard is constructed in the same way as OSB (Oriented Strand Board) wood products, using smaller pieces of wood bonded together with low emission resins to form a studio, structurally superior wood product. Rimboard is used around the entire perimeter of the floor structure to provide a smooth nailing surface for siding or siding.

OSB trim boards are manufactured from strands of wood that are oriented crosswise to provide strength and strength for suction cups, then bonded using high pressure and heat to form a strong, straight structural member. Rimboard is treated with a waterproof coating to prevent moisture from penetrating the surface. Engineered rimboard is stronger, straighter, and easier to use than dimensional lumber of the same size.

Using rimboard in conjunction with engineered wood I-joists will save time and money during the construction project. Rimboard is manufactured to match the exact depth of engineered I-joists, eliminating the need to cut standard dimension lumber that doesn’t come in sizes that correspond to common engineered joists. This saves time, money and waste on the construction site.

When used properly, rimboard becomes a structural component of engineered wood flooring, transferring both vertical and horizontal forces. When attached to the ends of I-beams, trim panel adds stability to upright members to prevent twisting or warping.

As with all engineered wood products, rimboard is an eco-friendly alternative to dimensional lumber construction. The smallest wood strands can be obtained from smaller, fast-growing trees, grown using sustainable forestry techniques, saving old trees. The resins used to bond rimboard are water-based, so they contain negligible amounts of toxins.

Integrating rimboard into your framing project using engineered wood products will provide the finishing touch to the framing portion of the project. Saving you time, money and material compared to standard dimension wood rim joists, rim panel is the material of choice. Being more environmentally friendly is just an added bonus when using rimboard, and we can all feel good about it.
