Intro

The construction of a terrace is an essential step to create a pleasant resting place, and the choice of material is decisive. Thermowood is becoming an increasingly popular terrace material, which stands out for its special recycling process. This wood undergoes heat treatment, which improves its physical properties and longevity. Anyone planning the construction of a terrace wants to understand what are the advantages and disadvantages of thermowood compared to traditional materials such as composites or pressure-treated wood. The article will analyze the main advantages and disadvantages based on the latest research and expert opinions. Practical examples will also be covered to help readers make informed decisions.

Context

The process of manufacturing thermowood is relatively environmentally friendly, as it uses high temperatures and steam without the use of harmful chemicals. As a result of this process, the strength of the wood increases, as well as its ability to absorb moisture decreases. It is important to understand what thermowood is and how it can compare with other terrace materials. The basic evaluation criteria include the longevity of the material, the maintenance requirements, the ecological impact and the cost. It is also necessary to consider where these materials can be purchased before making a decision.

Advantages

Thermowood planks have several significant benefits that make them a good choice for terrace construction.

First of all, thermowood is distinguished by its longevity. Studies show that the service life of thermowood can reach up to 25-30 years, which is significantly longer than that of natural wood. This characteristic reduces the need for frequent replacement and increases the return on investment over time.

Secondly, thermowood is resistant to moisture and deformation, which is the result of its heat treatment process. These boards retain their shape and appearance despite changing weather conditions and do not require additional chemical treatment against biodegradation.

Thirdly, thermowood is an environmentally friendly choice, since no harmful chemicals are used in its production. This reduces environmental pollution and promotes the sustainable use of local resources.

Drawbacks

Although thermowood boards offer many advantages, they also have a number of disadvantages.

One of the main disadvantages is the higher initial cost compared to traditional wood species and some composite materials. The process of manufacturing thermowood is more expensive, so prices can be twice as high as for raw wood.

Secondly, thermowood can change its color when exposed to UV radiation. This can affect the aesthetic appearance of the material if it is not treated with protective agents.

Finally, affordability can be a challenge, as reliable suppliers sometimes offer a limited range of thermowood models, which can limit the choice of buyers.

Is thermowood suitable for your climate?

Climatic conditions are an important factor when choosing terrace materials. Thermowood adapts well to humid climates, as its processing reduces moisture absorption. Consequently, when exposed to high humidity, thermowood turns out to be more durable than raw wood.

In addition, the dimensional stability of thermowood ensures its longevity in the face of temperature fluctuations. The material is less prone to expansion and contraction processes, so it is suitable even in regions with significant temperature changes.

Where can I buy thermowood boards?

It is important for potential buyers to know where you can buy thermowood boards. Various suppliers offer thermowood, including specialized stores and online platforms such as www.aiik.lvwhere you can find high-quality materials at affordable prices.

Choosing the right supplier is essential to ensure quality materials and good service. Domestic manufacturers often offer good prices, as well as additional services such as delivery.

Expert opinions: what do professionals say about thermowood?

Industry experts support the use of thermowood, citing its longevity and environmental friendliness. Kristaps Klauss, Executive Director of the Latvian Timber Industry Federation, believes that thermowood is a better choice compared to tropical wood. The representative of SIA “Thermory” Jānis Grīnbergs also emphasizes that thermowood requires minimal maintenance, which is important in the context of long-term economic considerations.

Conclusion: Is thermowood the right choice for your future terrace?

When evaluating thermowood boards, it is important to understand both the advantages and disadvantages in order to make an informed decision. Longevity, low maintenance requirements and environmental friendliness are essential considerations when choosing patio materials.

However, it is also important to consider the higher initial cost and potential color changes, as well as the availability of offers in the market. Every buyer should evaluate their needs and circumstances, as well as options for sustainable choices.

This information serves as a practical resource to improve understanding of thermowood as a material choice for your next terrace, promoting informed decisions and sustainable choices.
