How Shiplap and Tongue & Groove Differ

Gary discusses the frequently asked question of Reliance Timber. “What is the difference between shiplap and tongue & groove and which should I opt for?”

Gary Discusses How Shiplap differs from Tongue & Groove

Gary Campbell: Our clients commonly ask us, “What’s the difference between shiplap and tongue and groove?” So I’d like to show you what the difference is. We’ve got shiplap and you can see how one piece laps over the other. And in this case, this is nickel gap shiplap. So the only thing holding this to the wall or the ceiling is the nail.

Gary Campbell: If it weren’t for the nail, you could see how this would come right apart. All right. Then we’ve got tongue and groove and the groove joins together by the tongue and the groove. You join them together. In this case, this is nickel gap tongue and groove. When it comes to both shiplap and tongue and groove, we make a variety of profiles.

Gary Campbell: We can do tight fit. We can do nickel gap. We could do V joint edge. We could put a band saw face on it, or we could hand hew it, or we could just leave it smooth—whichever you prefer. I just wanted to share the difference with you. In my opinion, the way these join together, tongue and groove is better because you’ve got the tongue, the groove and the nail holding it. Whereas with shiplap, it’s just the nail.
