What’s Behind Your Cladding Matters!

Great cladding starts with what’s underneath.

It’s not just the boards that matter — the right subframe makes all the difference. Our highperformance battens are designed to provide strength, structure and essential airfl ow, helping your cladding look better and last longer.

Choose from a range of durable options to suit your project and get the finish your exterior deserves.

Cladco charcoal Signature composite cladding installed on a modern residential structure.

Recycled plastic decking joist installed onto Cladco concrete decking block as a decking subframe.

Don’t Forget About Your Base!

We understand how important a good, solid frame is to begin any garden decking project. At Cladco, we offer a selection of decking joists, posts and subframe fixings designed to provide your boards with the support they need.

FAQs

C24 timber refers to a type of timber that is 50% stronger than C16 timber and has significantly fewer knots. This makes it able to bear more weight and more suitable for longer spans or increased loads. It is also green-treated and FSC® certified.

Yes, the timber joists can be sawn, planed or drilled to fit the specifications of your decking project.

The lack of maintenance required for recycled plastic joists helps reduce future costs associated with decking projects.

Cladco 4m composite joists/battens provide a strong, low‑maintenance base for installing composite cladding. Made from the same durable material as our boards, they can be fitted vertically or horizontally depending on your design.

For wall cladding installations:

Install battens with maximum 500mm spacing for proper support.
Ensure the battens are fully supported along their entire length, as these joists are non‑structural.

These dark charcoal battens offer a sleek, weather‑resistant substructure that helps bring your cladding project to life. If you need structural joists or alternative materials, we also offer 100x50mm composite joists, and timber options.

Double joists are essential at butt joints because they provide individual support for each board end. Every board must be fixed independently, and this can only be achieved when there is a dedicated joist beneath each adjoining board.

Using two separate fixing clips—one for each board end—prevents boards from sharing a single clip. This is crucial because:

Each board needs its own secure fixing point
Independent clips help manage natural expansion and contraction
Boards remain properly aligned and supported over time
Movement at one board end does not affect the adjoining board

Following these installation requirements ensures that your decking performs as intended and maintains its structural integrity.

Not adhering to these guidelines may compromise the stability of your deck and will invalidate the product warranty.

Yes. While ideal for aluminium >, these joists are also suitable for supporting timber or composite decking boards, offering versatility across different project types.

Yes, the concrete foot is quick to install and can be repositioned with minimal effort.

They are used to provide a strong foundation for composite decking boards, ensuring everything is positioned correctly for a durable decking project.

I wasnt sure if metal battens were worth it but glad I tried them. The 50mm width did the trick for my composite cladding. Easy enough to screw in and felt proper solid once up. Staff on the phone were sound too, answered all my questions. Would buy again.
