Trim Head Siding Screws

The choice of an edge profile (shiplap versus square edge) is simply a matter of individual design preference. Here are some photos of the square edge profile in a couple of layout options:

All of our standard sample stock is cut from select-grade wood; whether samples have knots or not is a matter of chance. However, when a clear grade is requested, we take care to provide sample swatches without knots.

No, it is not mandatory to use our trims with your lumber package—however, we do recommend them for several reasons. Nakamoto Forestry aluminum trims are designed to simplify your project by ensuring a polished appearance, efficient installation, and optimal durability. If you choose not to purchase our accessory products, you can trim out corners and windows as you would any other wood siding. Most projects will need head or other flashing that is custom bent locally. 

While our aluminum trims serve a cosmetic function, it’s important to note that they are not a substitute for a comprehensive moisture management system. All accessories must meet our installation parameters as well as local code requirements. Ensure that exteriors are properly sealed and flashed to prevent moisture intrusion and install in a shingle fashion for effective management. 

Always consult with a design professional to review project installation parameters relative to your local building code and regional best practices for moisture and water vapor management.

It is common for locally sourced wood trim adjacent to our yakisugi scope to be painted, either to complement or contrast with our siding. We can supply extra oil stain for this purpose as part of your original lumber package or purchased separately from our online store. 

Please note that, even with multiple coats of oil, locally sourced wood products may not perfectly match the color and tone of our yakisugi “shou sugi ban” products. The opacity of the coating also plays a role, with more opaque coatings providing a better match. A semi-transparent linseed coating is harder to match than a semi-solid alkyd coating. 

Opting for a contrasting trim color/tone is also a common approach, which simplifies the problem of trying to match two different materials.

Nakamoto Forestry prioritizes sustainable sourcing and low carbon output for our products. Some projects may be eligible for LEED points due to our low carbon footprint. Please note, however, that our siding currently may not qualify for LEED points for two reasons. LEED gives points for local products within a 500-mile radius as well as for Forest Stewardship Council (FSC) certification, which is not available in Japan for the species and grades that we consume. LEED relies on FSC certification to validate the sustainability of materials.
