Cladding is the exterior of your timber building.

There are a variety of different types of cladding, and in this article, we will discuss two of the most common ones: tongue and groove weatherboard versus overlapping cladding.

The cladding is what keeps your shed weatherproof and secure.

Whether it’s beautiful red cedar in 32mm half log tongue and groove weatherboard, or 19mm Scandinavian redwood shiplap (overlapping cladding), it’s the looking after it that counts.

Treat your shed right and it’ll last you a lifetime.

We have laid out the pros and cons of tongue and grove weatherboard and overlapping cladding to help you decide which is the best for you.

Tongue and Groove vs Overlapping Cladding – What’s the difference?

Overlapping Cladding

What is overlapping cladding?

Overlapping cladding is when the timber is placed one on top of another so each of the boards overlap the previous one to create a panel. They are rough sawn and have more of a ‘rustic’ look.

Overlap Cladding

Pro’s of overlapping cladding

  • Advantages of this type of cladding is that it is the cheapest option in terms of cladding options.
  • It is also a desirable option due to it enabling the run-off of rainwater with ease

Con’s of overlapping cladding

  • A disadvantage to overlap cladding is that it isn’t very durable and means that it wouldn’t be able to support anything heavy such as shelving on walls
  • The timber used for this type of cladding is usually thin whitewood and therefore more likely to warp over time due to weather conditions.

Tongue & Groove weatherboard (cladding)

What is tongue and groove weatherboard?

Tongue & Groove is where a panel is created from planks of wood which are designed to interlock.

Timber is planed to allow smooth panels which join with ease. This result in the build having a neat, tight finish.

Pro’s of tongue and groove

  • Tongue and groove is our favourite for its strength and durability because of its interlocking system. It is also the most likely to remain straight and square over time.
  • The tongue and groove weatherboard profile above is ideal for running water readily off the panel.

Con’s of tongue and groove

  • This option comes in several thicknesses the thinner the board the less durability.
  • Tongue and Groove weatherboard is clean and dressed, which means it will most definitely cost more.

Cladding Thickness – What you need to know

Please note that the timber thickness is just as important a factor as the type of cladding.

A quick scan online can show that some of the cheapest timber buildings may have a ‘thickness’ of 8mm.

While the price will be less, it’s worth taking into account that there’s very likely to be a compromise in the quality of the build.
