What Does Shiplap Siding Look Like?
All shiplap siding for both home interiors and exteriors will rely on some tongue and groove cut to connect or "fit together" the different wood pieces. However, this doesn't mean that all shiplap siding will look the same. You can choose to install shiplap siding horizontally or vertically. However, horizontal is much more common and will be more accessible at local hardware stores and lumberyards. The way you finish the shiplap siding will also impact the final appearance. For example, a neat coat of glossy white paint (zero-VOC, of course) will allow for a clean and modernist finish. Painting shiplap siding with a natural-colored varnish (check out this Rise guide to healthy wood finishes for your home) will offer a more rustic, natural feel.
What Is the Best Wood To Use for Shiplap Siding?
In theory, you could make shiplap siding from any number of different types of lumber. In many cases, you might be able to find salvaged wood from old barns or century homes that are being torn down. Often, older homes utilize exclusive hardwood lumber that is exceptionally resistant to the elements and can last for centuries when proper care is taken. A local carpenter or lumber yard can repurpose some wooden planks from an old barn and even pre-cut the tongue and groove fits.
If you can't find salvaged wood and don't want to spend a fortune on fresh hardwood lumber, cedar is generally the best option. Cedar planks are more moisture-resistant than pine. They also naturally resist termites and other pests much better than pine. Suppose you plan to use shiplap siding as an exterior siding that receives driving rain or bathrooms, kitchens, or other interior spaces where moisture might be an issue. In that case, cedar is the way to go. Otherwise, cheaper pine lumber is a good option for most other spaces.
