Decks have been popular for many years but have risen in popularity in recent years, with many homeowners considering them an extension of their home - a very important extension. Whereas decks in the past were usually made of wood, we're now hearing a lot about composite decks and their advantages. Just what are composite decks and what's all the hype about? Are they better? Are they more economical? Why are so many homeowners choosing composite decks over wood decks?

What are composite decks?

Composite decks are made from a combination of wood fiber and plastic. When merged together, composite decking planks require less maintenance and generally have a longer lifespan than decks made of natural wood. This one feature alone has many people rushing out to get composite decking for their outdoor decks.

Composite decking is made of a blend of low or high-density polyethylene, polypropylene and polyvinyl chloride. Added to the mix is wood flour and additives, which help to strengthen the plastic and protect it from the damage caused by the sun's UV rays.

What makes composite decks so popular?

The reasons why so many homeowners are choosing composite decking is because of the low maintenance it requires. Unlike wood, it doesn't swell or shrink because it doesn't absorb or give off moisture. Because of these traits, it also will not warp, separate or crack with the changing seasons and weather.

Other things that make it ideal for decks are that it does not need to be sealed or stained and will hold up against cold weather. However, it is as easy to cut and install as real wood. Although the cost of composite decking is considerably higher than wood, the lack of required annual maintenance and care make up the difference to many.
