The Difference Between Tongue and Groove vs. Shiplap: Which Is Right for You?

Both tongue and groove and shiplap share an attractive look. Aesthetically, they give a slightly different but equally appealing country or cottage vibe that is popular in traditional and modern homes today. Additionally, both types of panelling evoke a natural warmth and charm that makes for a relaxed atmosphere in the spaces where we live and raise our families.

Yet, these two panel styles are also different. For instance, the way they fit together. Shiplap boards sport a rabbet joint. This is achieved by cutting a recess into the long sides of each panel. When set together, one slides overtop the other where they join. It’s a beautiful choice for interior designs. However, this type of joint sheds water really well. Therefore shiplap is the superior choice for exterior applications compared to tongue and groove.

Tongue and groove, on the other hand, makes use of a more complex join. Simply put, the tongue of one board slips in the groove on the one next to it. This type of join affords a tight seal, which adds durability. It also has superior insulating qualities and is popular for walls, ceilings and flooring alike.

Still, there are a few more things to consider when deciding which to use for your project. Shiplap tends to be cheaper because it’s easier to make. Additionally, it’s easier to install, which will lower those costs if you hire a contractor to do the work. However, it does require a bit more maintenance as dust has a tendency to settle in the gaps. It’s not a big issue, but if you don’t want to dust your walls, opt for tongue and groove instead.

We custom mill both types of panelling from high-quality lumber, in your choice of wood. Pine, fire and cedar are popular picks.
