DuoDeck Composite Decking

DuoDeck is a new and innovative brand of composite decking, designed to add a stylish deck to your garden, while being environmentally-friendly.

Made of a wood plastic blend, this decking consists of 60% natural wood fibres and 30% recycled HDPE plastic. These two materials are combined with bonding agents and tints to create an eco-friendly and sustainable range of decking that looks great, and will eliminate colour fading and rotting that is associated with traditional timber decking.

DuoJoist for Your Decking

DuoJoist Box Section Joist, also referred to as DuoJoist Bearer, is a long-lasting, hard-wearing alternative base to a traditional timber frame. This can also be fit onto an existing concrete base.

Measuring 15mm thick, the outer wall allows for strong fixing of the deck boards on top, ensuring sturdy and robust joist for any range of composite decking.

Benefits of using DuoJoist

• 10 year guarantee - designed to last a lifetime
• Will not rot or warp in shape
• Environmentally-friendly alternative
• Superior strength

Installing DuoJoist

Due to the complexity of installation, we recommend you hire a professional Landscaper to carry out the work. Corner metal trims and bolts are sold seperately and are required for installation. 

A maximum of 400mm centres between joists is recommended by the supplier.
