Shiplap vs. Tongue & Groove: Which Profile Is Best?

Shiplap vs. Tongue & Groove: Which Profile Is Best?

Published on Wednesday, March 30, 2016

Cladding is available in a range of profiles, all of which possess their own attributes, which make them the perfect choice for a various jobs. Two of the most popular are shiplap and tongue and groove (V-jointed on our website), and choosing between them can be a difficult task. To make this task a little easier for you, we’ll discuss the benefits of each, and how different profiles can apply to different applications.


European Shiplap Cladding

Tongue and groove and shiplap cladding do look very similar once installed. The main difference between them is a longer lip on shiplap cladding, which acts as an additional layer of protection against moisture and rainfall.

Because of this, shiplap cladding offers optimum rainwater resistance as this lip acts as a barrier, whilst also creating a small groove, allowing water to run off the shed/building it is placed on. This makes it a popular option for installations that need to withstand the elements and heavy rainfall.

This profile probably offers the best defense against water infiltration, with risks of rot and swelling dropping to a minimum.

Tongue and Groove

V-Jointed Tongue and Groove Cladding

Perhaps the most popular type of cladding profile is tongue and groove. This is not only due to its neat appearance, but also its ability to shield buildings from water and weather damage, much like shiplap. The interlocking joints provide a very effective shield from harsh weather conditions including rainfall, whilst also being a good insulator.

With tongue and groove, it’s essential to consider shrinkage during warm weather. This cladding should allow for shrinkage during installation, to prevent gaps appearing in the future. That said, the strength created when interlocking panels is truly impressive, and this profile should definitely be considered when looking to build a very sturdy structure.

So, overall the differences as fairly minimal but important to consider, the deciding factor may come down to appearance for your specific project.
