Recommended Wood Types for Decking: Treating Wood Against the Elements
When it comes to choosing the right wood for your deck, the decision isn't as simple as you might think. Various factors, including the environment, maintenance requirements, and ethical considerations, all play a significant role in determining the best material for your project. This article delves into the suitability of different types of wood for outdoor use, with a focus on treated wood and untreated options.
Why Treating Wood is Essential
Exposure to Elements: Decks are designed to be outdoor structures, which means they are inevitably exposed to various elements like rain, snow, and sunlight. Untreated wood, such as fir and hemlock, is not suitable for this purpose as it tends to rot, buckle, and split over time. Even when stained or painted, these woods do not provide long-lasting protection against the harsh conditions of the outdoors.
While some types of wood, like teak, can be more resistant to moisture and decay, they are often too expensive and unsustainable for most home projects. Teak, for instance, is an incredibly expensive and imprudent choice because it is a highly threatened species on the planet, primarily due to deforestation in the tropical regions where it is traditionally sourced.
Alternatives to Wood
An alternative to wood for decking is the use of engineered composite materials. These materials are created from a combination of wood fibers and synthetic polymers, making them highly resistant to weathering and decay. Engineered composites are not only durable but also offer a wide range of aesthetic options, from the natural look of wood to the colorful hues and textures of plastic.
Treated Wood: A Safer and More Practical Option
In the absence of engineered composites, treated wood is often the preferred choice for decks. Treated wood is chemically treated to make it resistant to decay and insect infestation. Pressure-treated lumber, for instance, is commonly used in building decks due to its ability to endure and resist moisture without splitting or checking. However, it is still essential to stain treated wood with a high-quality decking stain to enhance its appearance and protect it against sun damage and weathering.
Treated wood is generally more cost-effective and readily available than alternatives like composite materials. It is also a more sustainable option compared to premium woods like teak, as it comes from sustainably managed forests and is treated with less harmful chemicals.
Conclusion
In summary, while wood remains a popular choice for deck building, it is crucial to consider the types of wood available and their suitability for outdoor use. Untreated wood, such as fir and hemlock, is not suitable for use in decks due to its susceptibility to rot and weather damage. Treated wood, on the other hand, is a safer and more practical option, providing a durable and long-lasting solution for outdoor structures. Alternatively, engineered composite materials offer a more durable and sustainable solution, but they may not be as cost-effective or as readily available as treated wood.
