About Our 4m Composite Joists/Battens
Bring your composite decking or cladding to life with Cladco 4m composite joists/battens. Designed as a vital structural component, these joists and battens provide reliable support for the installation of composite boards.
Ideal for use as decking joists, they offer a durable, weather-resistant base for your outdoor space. Alternatively, they can be installed as cladding battens, either vertically or horizontally, depending on your project’s design. Made from the same composite material as our boards, they offer a consistent, low-maintenance solution for any outdoor build.
Joist specifications

Height: 30mm
Weight: 5.16kg approx.
Cladco composite joists and battens are supplied in a dark charcoal colour, providing a sleek and modern finish to any substructure. For decking installations, joists should be spaced no more than 400mm apart, while for wall cladding applications, battens should be spaced at a maximum of 500mm apart to ensure proper support.
As a general guideline, we recommend one joist per square metre of decking. For best results, especially in decking projects, joists should be installed over a solid concrete base to create a sturdy, long-lasting foundation for your outdoor space.
