Why Composite Decking is a Better Choice than Wood Decking

Why Composite Decking is a Better Choice than Wood Decking

Composite DeckingWhen it comes to decking, composite decking is a far better option than wood and there are many reasons for this. You can choose PL (plastic lumber) composite or WPC (wood plastic composite) over wood because your finished project will resist rot, harsh sunlight, wood-consuming insects and mold and mildew, and also you will never have to paint it.

Do composite decking materials deliver? Well, yes, in many respects. But if you ask if they don’t require maintenance, the answer is ‘no’, as with any other material. While many of these materials carry massive warranties from 25 to 50 years that offer protection against rotting, peeling, insect infestation and splitting, these decks do buckle, fade and harbour mildew in certain situations, particularly if they contain wood fibres.

However, PL and WPC decks don’t need the yearly makeover needed by wood decks and most last for decades if you give them a little more than water and soap rinses.

PL and WPC decking often consist of a thermoplastic, like polyethylene that is recycled from old plastic bags and bottles. Composite lumbers have other materials too like sawdust, wood flour or ground peanut shells. They can either be solid all through or may have a hollow, ribbed centre to lessen weight. (Some solid-core products may weigh as much as 5 pounds per foot and this is thrice heavier than cedar). High-end composite decking is usually enclosed in a plastic shell that fights staining, fading, mold and scratches.

Before you install the product, it’s essential to read the manufacturer’s instructions carefully. In hot air, it expands more than wood across the length but less along the width. The longer the piece, the greater will be its expansion and you have to prepare for this while building your deck.

Also check the end-gap chart of the product that associates the space required between the ends of two pieces of decking with the length of each of them, the temperature at the time of installation and the highest possible temperature in the deck area.

Also remember that this material is bendy as compared to wood. Not all of them are designed to span joists on 16-inch centres; some work on 12-inch centres. There is one benefit of this however and it’s that you can have curvy designs which are not possible with wood lumber.

Remember these things to have a wonderful decking to spend time as a proud homeowner.
