Composite boards are one of the best materials that you can use to build decking. The reason homeowners considered them to be one of the best is that they are durable. Aside from being durable, plastic wood decking is resistant to water and snow. So, will my composite decking swell? No, composite decking will not swell and rot like wood decking. Let’s consider why.

Why Composite Decking Will not Swell

Composite decking has a well-improved surface texture that makes it absorb less moisture. What this well-engineered surface does is that it reduces how water from rain or damp air enters into the composite boards.

 Water or moisture is bad for decking material. When you install decking in an outdoor space, you will expose it to the various weather elements. Those weather elements include snow, rain, ice, water, damp air, and heat. All these weather elements act to destroy or reduce the durability of the decking. 

This is where composite decking improved surface texture comes in. The top or outer sides of composite decking have a plastic covering. This plastic-coated surface acts to stop excess water or moisture from entering your composite decking. So, your composite decking will not swell like wood decking. 

decking that will not swell

Timber decking is not a synthetic material like plastic wood decking. Wood readily takes in moisture from the air, or ice, snow and water. When this happens, wood decking will swell or increase in size. This means that timber will eventually rot if the moisture doesn’t dry on time.

 If the moisture dries on time, wood decking will shrink or break. Your composite decking will not swell and rot. Also, composite decking will not shrink or break the way timber will.

Other Benefits of Composite Decking

That composite decking will not swell, and rot is part of its durability. Durability is when an outdoor building material withstands external pressure successfully. Composite decking will not only withstand swelling; it will also resist warping or sagging. 

Composite Decking Will not Warp or Sag

Warping is when the surface of decking is distorted because it peels. This occurs in wood decking, and it is as a result of temperature change. When the weather is hot, wood decking expands and contracts when the weather cools. 

This expansion and contraction of wood decking will cause the surface or the top to peel or warp. A warped decking will not be good to look at or to walk on. Composite decking will not warp because of its well-engineered plastic-coated surface. This means that the plastic wood decking surface will stay the same throughout.

Composite Decking Will Resist Termite Attack

Another benefit of composite decking that is different from swelling is that it will resist insect attack better than wood decking. Timber decking is food for insects; that is why termites will readily eat it.

 Although some wood deckings are treated with chemicals, they will lose their durability over time. Composite decking is not food for insects because it is an artificial decking. So, if you build your plastic wood decking in a termite area, they will not destroy it.

Composite Decking Is Lightweight and Strong

This is one benefit that is similar to the fact that composite decking will not swell. The advantage of lightweight is that you can carry or lift your composite decking from one place to another.

 Unlike wood that is dense or heavy, composite decking is not heavy and at the same time strong. Also, since your plastic wood decking is stronger than wood, more people will be able to stand on your decking, and it will not cave in. 

Composite Decking Is Easy to Install

Another benefit of plastic wood decking other than no swelling is that it is easy to install. When you want to build your composite decking, you can easily cut the boards with a saw. Aside from that, there are grooved composite decking boards. You can use hidden clips to fasten grooved decking.

 Pre-drilling composite decking is easy. With a drilling machine, you can easily make holes in your composite decking boards so that they will not split when you want to screw them. You can easily attach composite decking to the joists when building it. So long as you leave the right amount of space between the boards, they will expand without breaking.

Conclusion

Will composite decking swell? Composite decking has a well-engineered surface that prevents it from absorbing water and from swelling. This suggests that your composite decking will not rot, warp or splinter.
