Composite Joist/Battens Features and Benefits
Create a durable, weatherproof, and low-maintenance foundation for your composite decking by using our low-profile composite joist for your decking frame. Our composite battens are everything you need to make your project a success. Our composite joist is engineered to resist rotting, warping, splintering, and splitting, ensuring long-lasting support without the need for treatment or frequent replacement like traditional timber joists. Designed for versatility, it can be installed either side up and is ideal for solid, weight-bearing bases such as concrete. To attach your decking boards securely to our composite battens, use our range of decking clips, which perfectly complement the composite joist system. Additionally, the composite joist serves as an excellent frame for composite cladding. Simply attach it to the wall or structure, and install the cladding directly over it for a sleek, secure finish. Our Low Profile Composite Battens are not suitable for raised decking projects – we recommend using adjustable pedestals and aluminium joists instead.Composite Joist FAQs
What joists do you use for composite decking?
Composite decking requires durable, moisture-resistant joists, such as aluminium or composite options, to ensure long-lasting support. The joist choice impacts stability, especially with low-profile designs, making high-strength materials essential.
How do you fix composite decking joists?
Begin with a secure, level base. Use fixings like stainless steel screws or clips designed for composite decking. A fixing should be at every point a board crosses a composite joist.
How do I install composite decking?
Install composite decking by aligning boards perpendicularly to the joists. Maintain consistent spacing between boards to allow for expansion, and use clips or screws to fix boards securely, starting from the centre outward. Read our full composite decking installation guide for more support.
What is the difference between composite joists and battens?
Joists are primary support beams used beneath the decking, designed for durability and load-bearing, while battens are typically lighter, offering spacing and ventilation. Composite joists provide a robust, rot-resistant alternative to wood.
Our Dino Decking composite joists/battens offer exceptional decking support, suitable for all types of builds with the exception of a raised deck. The composite material is both breathable and durable which stands the test of time.
Can composite decking be laid on wooden joists?
Yes, provided the wooden joists are in good condition, level, and properly spaced. However, we generally recommend composite joists as wood can rot over time, reducing the deck’s lifespan.
How far apart joists should you place joists/battens?
Standard spacing between composite decking joists is usually 300mm, depending on board width and expected load. Proper spacing ensures stability and prevents board sagging.
When used as composite battens for wall cladding the recommended spacing is typically at 300mm centres, depending on the cladding manufacturer’s guidelines and the batten’s strength. This spacing supports the cladding boards adequately, ensuring even load distribution and long-term stability.
It’s also essential to consider factors like climate and exposure to wind or heavy loads, as these can impact spacing needs.
It would be a 5 star review however there was a slightly chipped decking plank and a slightly dented joist. As it turns out they were both in positions that don’t matter.
Delivery was quick and the delivery person was very helpful and informative.
I’ve made 2 large orders and both were delivered really quick within 1-2 days. The quality of the Composite Decking and associated products of support Joists, fixings are excellent. I installed it all myself (not a professional) and it all went together very well. I would highly recommend Dino Decking.
I had decking boards, joists and fasteners delivered by Krystian. This is my first time using the composite decking and so far I’m very happy with the quality of the material. The driver was not just very helpful with the delivery but also very knowledgeable about the product and offered some useful installation tips! Great stuff!
We purchase, joists, decking and trim and are very pleased with the result. Not the cheapest product but good quality. All the fittings were there and also good quality.
The delivery driver was a lovely guy and very helpful.
Will use them again when we build the next deck around the backef our house.
We were unsure about ordering our decking on line, however, Dino Decking were impressive from out first contact. We ordered a sample box which arrived promptly with a brochure providing information about product options. We did the call the company a couple of times with queries and on both occasions, the phone was answered promptly (by a real person!) who was able to provide the information we needed. An email we sent was also responded to quickly. The impressive customer service made us feel confident to proceed with an order for joists, boards and fixings for a 5.2x4m deck. Once we ordered, the products arrived within 5 working days, the delivery driver phoned an hour beforehand as promised and was friendly and helpful.The products were all as described and we did not experience any problems constructing the deck. It has only been in place 2 weeks, so I cannot comment on wear and tear, however, to date, we have been very impressed with Dino Decking and would not hesitate to recommend the company.
