Benefits of Choosing WPC Decking


Eco-Friendly and Sustainable

 

WPC decking, or Wood-Plastic Composite decking, is a great choice compared to regular wood floors. It works well for outdoor spaces. It's made from recycled wood bits and plastics. This makes it kind to the environment. WPC decking uses wood waste and plastics that can be recycled. This cuts down on harm to nature during production. It helps save trees and keeps plastic waste out of landfills.

Plus, WPC decking is fully recyclable. Old or damaged WPC boards can be reused. This makes it super eco-friendly. Many homeowners and builders pick WPC because it supports green building ideas.


Safe and Comfortable for Families

 

WPC decking is safe and comfy for daily use. Its surface has natural bumps and grooves that stop slipping. This keeps it safe, even when it’s wet or rainy. It’s perfect for homes with kids or older people who need steady footing.

Also, WPC decks don’t splinter like wood. So, bare feet are safe on it. The material fights off mold and mildew because it resists water. This makes it great for pool areas or damp places.

Why Proper Installation Matters for WPC Decking


WPC decking must be installed on a substructure made of joists

 

The joists provide essential support and ensure that the decking boards remain stable, level, and well-ventilated over time. Without proper joist installation, the decking may experience issues such as sagging, uneven surfaces, or poor drainage.

Whether you're using WPC joists, wood joists, or aluminum joists, a solid and correctly spaced substructure is key to maximizing the performance and lifespan of your WPC deck.

When installing WPC decking, you can use MexyTech’s adjustable pedestals to simplify and speed up the installation process. These pedestals allow for precise height adjustment, making it easy to level the decking on uneven ground without the need for complex groundwork. Plus, This system not only ensures a cleaner, more professional finish but also significantly reduces labor time and installation costs—especially on large projects or rooftop terraces.

Comparing Three Common Joist Types for WPC Decking


Wood Joists: Mostly for Renovation

 

Wood joists are often used when fixing up old decks. They’re a cheap option when swapping old wood decks for new WPC surfaces without changing the frame.

But they have downsides:

They can rot in wet places.

Bugs like termites can harm them.

They don't last as long as newer materials.

Wood joists are mainly used to renovate old wood floors with WPC. For new projects, people usually avoid them.


WPC Joists: Affordable but Limited

 

WPC joists are light, easy to put in, and don't cost much. This makes them great for projects on a budget.

But they have limits:

They're not as strong as metal joists.

They're not good for heavy-use areas.

They might bend in extreme weather over time.

WPC joists work well for small home decks or places with light foot traffic. But they may not hold up for busy or commercial spaces.

Aluminum Joists: Durable and Reliable


Aluminum joists are the strongest choice, though they cost more at first. They have a great strength-to-weight ratio and don't rust easily.

Their benefits include:

Super strong, meeting engineering standards.

Top fire rating (ASTM E84 Class A).

No cracking and less damage during transport.

A solid, steady structure that stops bending.

But they have downsides:

      It will expand and contract with heat

      The keel may bend, causing the deck to warp or crack.

So, they're perfect for: business spaces, heavy-load areas, places with tough weather. Though they cost more upfront, Aluminum Joists save money over time. They prevent issues like sagging or rotting.
