Longevity and durability of thermowood wood in the outdoor space
Introduction
The nature of thermowood and the reason for its resistance
The influence of climate and weather conditions
The role of lubrication and surface protection
Correct thickness, cut and foundation
Also, the suitable thickness for use on the exterior is usually between 18 and 26 mm. Thinner woods have a shorter lifespan and change shape faster in front of direct sunlight.
At the same time, screwing with stainless connections and using expansion joints in the corners are vital operational points that the Azar Wood installation team fully complies with. This accuracy in executive details is the main difference between a 5-year-old thermowood and a 30-year-old thermowood.
The effect of sunlight and UV rays
Ultraviolet rays of the sun over time cause the surface decomposition of wood and graying of the outer layer. Thermowood is not inherently UV resistant, but with the right protective coatings, this weakness can be completely covered. In Azar Wood, oils are used that include UV filters and light color additives so that the sun's rays affect the color of the wood less.
If you live in a very sunny area, choosing a light shade suitable for thermo color (for example, from caramel to burnt brown) will especially help to maintain the beauty of the appearance.
Thermowood with clear or natural UV coating usually lasts up to 5 years without needing to be repaired, and with just a new layer of oil, it will shine again like the first day.
Periodic maintenance and increase of useful life
One of the most important mistakes of users is that they think Thermowood does not need any maintenance. While correct and simple maintenance every year can double its life.
Azar Wood's suggested steps for taking care of thermowood outdoors are as follows:
- Gently washing the surface with water and a soft brush once every six months
- Annual oiling with UV-protect vegetable base oil
- Inspecting screws and connections once every two years
- In coastal projects, re-oiling is recommended every 8 months
These guidelines are fully tested and designed based on field data from real projects in different regions of the country. For this reason, the Azarwood brand is the only manufacturer that officially offers a 10-year maintenance warranty for post-installation services.
Choosing the right thermowood based on the place of use
External space includes different parts: building facade, pergola, flooring, flower box, fence and even the doors of the area. The required resistance is different for each section.
At Azar Wood, we propose the type of thermo exclusively by examining the location and use of the project. For example:
- Pine grade A suitable for facade and pergola
- Ash thermo with high hardness suitable for flooring and stairs
- Radiata thermo suitable for hot and dry climates
This specialized choice prevents early maintenance and replacement costs and creates significant economic savings in the long run.
summary
The durability of thermowood in the outdoor space is the result of the combination of three key factors: production quality, proper installation and regular maintenance. If each of these steps are done correctly, the lifespan of the wood is guaranteed for tens of years.
In Azarwood brand, all these steps are carried out under the supervision of the technical team and are accompanied by an official guarantee. The wood that you choose today for the facade of your house or cafe, if properly cared for, can maintain the same feeling of warmth, originality and brilliance as it did on the day of installation for the next thirty years.
Finally, Thermowood is not just a material; It is a choice to create spaces that become more beautiful with the passage of time. And we at Azar Wood guarantee this lasting beauty.
