Expert Advice On Our Walnut Composite Decking
Want to know more? Our in-house expert, Allan, gives his take on our Walnut 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 original composite decking lines were all about perfecting the blend of quality and affordability. But we didn’t stop there. We listened to our customers as they asked the next logical question: ‘How can we get even closer to the authentic look of real, weathered timber?’
Our answer was to stop thinking in single colours. For our Mixed Walnut, we developed a process to blend lighter and darker shades of dark brown throughout a single board. This, combined with our unique wood grain texture, creates a level of depth and natural inconsistency that you just can’t get with a standard board. It’s the perfect choice for a truly authentic, high-end look without
FAQ About Our Walnut Boards
1 Will the walnut boards fade in sunlight?
A small degree of colour softening (up to 20%) is natural with all composite products. However, our advanced surface treatment increases UV resistance, ensuring this softening is gradual and results in a beautiful aged finish rather than a bleached look.
2 Can I install this wood grain decking myself?
Absolutely. With a grooved edge that works with hidden fasteners, these boards are designed for straightforward installation. No specialist tools or trades are required; just follow our easy-to-use installation guide.
3 Are the boards slippery when wet?
Our Exclusive Collection has enhanced slip resistance, even in rainy conditions. Whether you’re barefoot or in boots, your deck remains safe underfoot.
4 How do I choose between the two sides?
It’s completely up to you. The reversible board offers a woodgrain finish for a natural, rustic appeal and a grooved side for a modern, linear look. You can even mix and match in your layout for added interest.
5 Is this decking eco-friendly?
Yes. Our composite boards are made from a blend of recycled wood fibres and plastic, reducing demand for new timber and lowering your environmental footprint.
