Expert Advice for 3.6m Composite Decking
Want to know more? Our in-house expert, Allan, gives his take on our 3.6m Composite Decking, and we’ve selected some of our best guides to help you decide if this is the right choice for you.
A Word from Our Expert, Allan:
Our 3.6m boards are one of the most popular lengths on the market, and for good reason. They strike the perfect balance—long enough to cover ground quickly for a faster installation, but still a manageable size for easy handling. It’s a versatile, all-around great choice for many decking projects.
After guiding thousands of customers, one thing became clear: the right board length is just as important as the right colour. We understood this early on and are proud to be one of the first providers in the UK to offer a vast range of lengths to suit any garden, big or small. The reason is simple: we listen.
-
Flexible & Manageable Size
The 3.6m length strikes the perfect balance between fast coverage and easy handling, making it ideal for intricate or staggered layouts with minimal waste.
-
Dual Finishes in One Board
Every board is reversible. Choose the deep embossed wood grain for a traditional timber effect, or flip to the narrow grooves for a clean, contemporary finish.
-
Heavy-Duty, Lightweight Core:
Our innovative four-square hollow design keeps each board light enough for solo handling, yet tough enough to withstand year-round use and heavy foot traffic without cracking or warping.
-
Effortless Long-Term Upkeep
No painting, staining, or sealing is required. A simple wash with soapy water is all it takes to keep this high-impact deck looking its best.

FAQ About Our 3.6m Decking Boards
1 Are our 3.6m boards prone to fading?
Our advanced surface treatment offers enhanced UV resistance, though you may notice a slight lightening (up to 20%) in the first few months. This is a natural settling process and results in a rich, even tone.
2 Can I install this myself?
Yes, absolutely. The 3.6m length and lighter weight make these boards especially manageable for DIY installation. The grooved sides ensure compatibility with hidden fastener systems, keeping your deck sleek and screw-free.
3 What’s on the reverse side of the board?
One side features an embossed wood grain finish for a natural timber effect, while the other offers linear grooves for a more refined, modern look. Both options are slip-resistant and stylish.
4 Do I need to seal or treat the boards?
Not at all. Composite boards are designed to be low maintenance, with no need for sealing, painting, or staining—saving you both time and money.
5 Are they environmentally friendly?
Yes, our composite decking is made from a blend of recycled plastics and reclaimed wood fibres, offering a sustainable and eco-friendly alternative to traditional hardwood decking.
