Composite decking is the modern outdoor flooring material that was developed to replace wood or timber decking. Treated wood is a type of decking material, and homeowners have long used it before developing composite decking. To know the difference between composite decking and treated wood, we must consider both decking type—composite decking vs treated wood. Let’s commence with treated wood.

What Is Treated Wood?

This is a kind of wood or timber decking that has wood fibre as its primary material composition. Note that there are two kinds of wood decking. The first is treated wood decking while the second is hardwood decking. The difference between treated wood and hardwood decking is that the former contains chemicals while the latter does not. 

After wood decking makers have shaped the wooded boards that they will use to make the decking, they will treat them with chemicals. The essence of treating treated wood with chemicals is to make it strong. Without chemicals, treated wood will lose its durability quickly and disintegrate.

How Is Treated Wood Used?

Treated wood is used for outdoor decking. You want to build or install decking in your back garden, you can use treated wood materials or boards. When you use treated wood to build your decking, you will have the chance of painting the boards to any surface pigment of your choice. 

Treated wood decking is not expensive, and with a small budget, you can build a treated wood decking. If you love brown surface pigment, you can give your treated wood decking a brown paint. But treated wood has its downsides.

Disadvantages of Treated Wood

Laborious Maintenance

The major downside or disadvantage of treated wood decking is that the way you maintain it is laborious. What laborious means here is that you must stress yourself if you want your treated wood decking to last long. You have to get sandpaper to sand the surface of your treated wood decking because it must be smooth before you paint it. 

After sanding your treated wood decking, you can then apply the stain or paint of your choice. Note that the reason you must paint your treated wood decking regularly is that the surface pigment fades on time. Besides painting, you have to scrub the top of your treated wood to remove mould and mildew if they grow on it. This makes maintaining treated wood decking laborious.

Durability

The durability rating of treated wood decking is low. This implies that treated wood will not last as long as composite decking. If rain touches the surface of your treated wood decking, it will absorb it and swell. Eventually treated wood decking will rot. This decking type will splinter or warp as a result of temperature change. The lifespan of treated wood decking is 10 – 15 years.

What Is Composite Decking?

Composite decking is the modern decking material that will not only provide extra outdoor space for you but will beautify where you install it.
