When you want to beautify and make your outdoor living spaces functional, choosing the right deck becomes an important decision. In this regard, Thermowood and composite decks are among the most popular options. When deciding which material is right for you, it's essential to consider the advantages and disadvantages of both options. At Novawood, we want to help you by comparing these two materials in detail.

Thermowood decks

Material composition: Natural wood modified through a heat treatment process-controlled environment with steam, without the presence of oxygen.

Longevity: Can last 25-30 years or more with proper maintenance.

Natural look and feel: Thermowood retains the natural grain and beauty of real wood, offering a rich and warm aesthetic

Wide range of options: Thermowood decks can be made from various types of wood such Ash, pine, iroko, teak etc. Each one has different durability and aesthetic features.

Enhanced durability: The thermal modification process enhances the stability of wood, reducing the risk of warping, shrinking, or swelling, while simultaneously increasing its resistance to rot, decay, and insect attacks without the need for chemical preservatives.

Eco-friendly: Thermowood is made from sustainably sourced timber and treated using a chemical-free process involving only heat and steam, making it fully biodegradable and environment-friendly.

Carbon storage: Thermowood products act as carbon sinks, storing carbon absorbed from the atmosphere during the tree's growth. By using Thermowood decking, carbon remains stored in the wood for the duration of its lifespan, further offsetting carbon emissions that would otherwise contribute to climate change.

Minimal maintenance: Thermowood requires minimal upkeep, needing only periodic cleaning to stay in good condition, and its natural resistance to the elements reduces the need for frequent treatments or repairs

Aging gracefully: It can be left to weather naturally to a silver-grey patina or maintained with oils to keep its original colour.

Ease of installation: Thermowood can be installed using standard tools and fasteners, similar to traditional wood decking, making it accessible for DIY projects.

Lightweight: Its lightweight nature simplifies handling and installation.

Initial cost: Thermowood may entail a slightly higher initial cost compared to traditional wood or certain composite options, but its competitive pricing emphasises long-term value and reduced lifecycle costs due to its durability and low maintenance requirements.

Composite decks

Chemical use: The production of composite decking involves plastics and other chemicals, which can have environmental drawbacks despite the use of recycled materials.

Synthetic look: While composites are designed to mimic wood, they can look and feel artificial, especially upon close inspection. The uniformity can lack the unique character and variation of natural wood.

Expansion and contraction: Composite materials can expand and contract with temperature changes, potentially leading to warping, cracking, and gaps over time. This can compromise the deck's appearance and structural integrity.

Heat retention: Composite decking can retain heat, especially in hot climates or when exposed to direct sunlight for extended periods. This can make the surface uncomfortable to walk on barefoot.

Environmental impact: While composite decking contains recycled materials, the production process may still involve the use of chemicals and energy-intensive manufacturing methods, contributing to environmental concerns.

Carbon footprint: Composite decking has a significant carbon footprint due to high energy consumption during manufacturing, reliance on non-renewable petroleum-based plastics, limited recyclability leading to increased landfill waste, the release of harmful chemical additives into the environment, and potentially shorter lifespan requiring additional resources for replacement or disposal, exacerbating its environmental impact.

Limited repair options: Composite decking presents challenges in repair and maintenance. While it is durable, staining, scratching, or damage may occur, making repairs to composite boards challenging and potentially costly. This may involve the use of specific cleaning products, specialised kits, or even the replacement of entire sections.

Colour fading: Some composite decking products may experience colour fading over time, particularly in areas with intense sunlight exposure. Choosing high-quality composite decking with UV protection can help mitigate this issue.

Things to consider when making your decision

Climate conditions: Your area's climate is crucial when selecting a deck. Thermowood decks are generally more adaptable to various weather conditions, making them an ideal option. However, composite decks have several drawbacks in different climates. In hot weather, it retains heat, making it uncomfortable to walk barefoot, especially during the warmer months. Additionally, it's prone to expansion and contraction with temperature fluctuations, leading to warping, buckling, or gaps between boards, affecting both appearance and structural integrity. In humid areas, mould and mildew growth are common, requiring regular cleaning for maintenance. When wet, composite decking can become slippery, increasing the risk of accidents, especially in rainy or snowy conditions. In cold climates, it may suffer damage due to freeze-thaw cycles, leading to cracking or delamination, which is important to consider when making your decision.

Budget: Your initial budget and long-term investments may influence your decision. Both Thermowood and composite decks may have higher initial costs, but Thermowood generally requires minimal maintenance, such as periodic cleaning. On the other hand, composite decking may require occasional special cleaning products and repairs for scratches or damage, which can add to the overall cost.

Environmental impact: Take into account the environmental impact of each material. Thermowood is made from sustainably sourced timber and undergoes a chemical-free process, making it environment-friendly. Composite decking often contains recycled materials but may involve the use of chemicals in its production.

Aesthetic preferences: Consider the appearance of each material and how it complements your outdoor space. Thermowood offers a natural wood look with warm tones, while composite decking often lacks the authentic texture and grain patterns found in natural wood, resulting in a less organic and more artificial appearance.

Installation: Consider the ease of installation for each material. Both composite and Thermowood decking can be installed using standard tools, but Thermowood may be lighter and easier to handle.
