Why would I have composite decking over tanalised timber ?

There are several reasons why you might choose composite decking over tanalised timber:

1. Durability: Composite decking is more durable and long-lasting than tanalised timber. It is made from a combination of wood fibers and plastic, which makes it resistant to rot, decay, and insect damage. In contrast, tanalised timber is treated with a chemical preservative to protect it from rot and insects, but it can still suffer from wear and tear over time.

2. Low maintenance: Composite decking requires very little maintenance compared to tanalised timber. It doesn't need to be stained, sealed, or painted, and it is resistant to fading and discoloration. In contrast, tanalised timber needs to be regularly maintained to keep it looking good and to protect it from the elements.

3. Aesthetic appeal: Composite decking is available in a wide range of colors and styles, so you can choose the look that best suits your home. It can also be made to look like natural wood, giving you the best of both worlds. In contrast, tanalised timber is limited to the natural color of the wood, which may not suit all homes.

4. Environmentally friendly: Composite decking is an environmentally-friendly choice because it is made from recycled materials. In contrast, tanalised timber is treated with chemical preservatives, which can be harmful to the environment.

Overall, composite decking offers a number of benefits over tanalised timber, including durability, low maintenance, aesthetic appeal, and environmental friendliness.
