When enhancing your outdoor space, choosing the right decking material can significantly influence both its look and functionality. Tanaised decking is a popular choice among homeowners for its mix of durability and style. However, it has its distinct advantages and drawbacks. In this blog post, we will examine both sides of tanaised decking to help you make an informed decision for your outdoor area.
What is Tanaised Decking?
Tanaised decking is crafted from treated timber, specifically designed to resist decay, insects, and harsh weather conditions. The treatment process involves applying preservatives that deeply penetrate the wood, making it suitable for outdoor environments. This type of decking is often chosen for its natural appearance and seamless integration with various landscapes.
Advantages of Tanaised Decking
1. Durability
The primary advantage of tanaised decking is its remarkable durability. Thanks to the treatment, the wood can withstand rot and insect damage, enabling it to last for many years. For instance, a high-quality tanaised deck can last up to 25 years with proper care. This durability allows homeowners to enjoy their outdoor areas without the constant worry of maintenance or replacement.
2. Aesthetic Appeal
Tanaised decking showcases the natural beauty of wood, creating a warm and inviting atmosphere for any outdoor space. Its rich tones and textures can harmonize beautifully with various architectural styles. Whether paired with a modern home or a rustic lodge, tannised decking enhances the visual appeal, making your garden or patio an inviting retreat.
3. Cost-Effective
When compared to other decking options, such as composite or exotic hardwoods, tanaised decking often comes at a lower price point. For example, homeowners might spend around 20-30% less on tanaised decking compared to composite alternatives without sacrificing quality. This cost-effectiveness makes it an appealing choice for those looking to enhance their outdoor area on a budget.
4. Environmentally Friendly
Most tanaised decking products are made from sustainably sourced timber, making them more eco-friendly compared to synthetic choices. The treatment process also extends the wood's life span, reducing the need for early replacements and minimizing waste. According to a study, treated wood can last significantly longer than untreated options, further reducing environmental impact.
5. Easy Installation
One of the biggest draws of tanaised decking is its relatively straightforward installation process. Many DIY enthusiasts find they can install it themselves with basic tools and some guidance. This ease of installation allows homeowners to create their dream outdoor space without incurring additional labor costs.
Drawbacks of Tanaised Decking
1. Maintenance Requirements
While tanaised decking is designed for durability, it is not completely maintenance-free. Homeowners need to clean the decking regularly and can expect to reapply protective coatings every few years to prevent fading and wear. A well-maintained tanaised deck can remain beautiful, but neglect can lead to costly repairs down the line.
2. Potential for Warping
Like any wood product, tanaised decking can be prone to warping, especially in extreme weather conditions. Homeowners should be proactive by ensuring proper drainage and ventilation in their outdoor spaces. For instance, avoiding direct contact between the deck and soil can help mitigate moisture-related issues.
3. Chemical Treatment Concerns
Some may be concerned about the preservatives used in the tanaising process and their impact on the environment. While these treatments are designed to protect the wood, they could potentially affect nearby plants and wildlife. If you're environmentally conscious, be sure to choose a product that uses safer, less toxic preservatives.
4. Slippery When Wet
Tanaised decking can become dangerously slippery when wet, which could pose a safety risk, especially for children or elderly individuals.
5. Limited Color Options
Although tanaised decking offers a pleasing natural wood appearance, it may have fewer color choices compared to composite materials, which come in a wide variety of shades. Homeowners seeking a specific color or finish might find the options limited with tanaised decking.
