Composite Decking: Types and Benefits

Reading time: 1 minute

Composite decking is made from artificial deck boards manufactured by mixing recycled plastics, waste wood fiber, and bonding agents. Composite decks require less maintenance and offer more design flexibility than traditional wood decking.

Composite decking, also referred to as wood-plastic composite (WPC) decking, is gaining popularity as it conserves natural wood and is environmentally friendly. 

This article discusses the types and advantages of composite decking used in construction.

Types of Composite Decking

Composite decking can be classified into:

1. Solid composite decking
2. Hollow composite decking
3. Capped composites

1. Solid Composite Decking

Solid composite boards are heavy boards used commonly to make permanent floors for houses, offices, and hotels.

Solid composite deck boards are strong and durable. They are used for swimming pool decks, pathways of houses, etc.

The two main disadvantages of a solid composite deck are that they undergo warp during extreme weather conditions, and as they are heavy, the installation requires assistance.

2. Hollow Composite Decking

Hollow composite decking boards or blank composite boards are lightweight decking materials often used for installing cables, cladding, siding, etc. They are less resistant to impacts. They require caps or fascia boards on their edges. 

3. Capped Composite Decking

Capped composite deck board consists of a core and a cap. The core is made from organic wood filler and recycled plastic material, while the cap is made from a synthetic material to increase the resistance to stain, scratch, and discoloration. 

Capped composite boards are used for garden areas, swimming pool decks, outdoor pathways, etc., for areas exposed to extreme wear and tear or weather conditions. 

Advantages of Composite Decking

1. Composite decking requires less maintenance compared to wood decking. 
2. They are highly durable and compacted to wood decks.
3. These deckings come in a variety of colors and shades.
4. Composite deck boards are made from recycled materials, making them environmentally friendly.

Composite decking cannot provide the exact finish and beauty of wood decking. Their costs are higher than other traditional materials. The normal cost of composite decking is $5 per square foot, excluding installation costs. Hence, they are a great choice where low maintenance and highly durable decks are required.
