Wooden facades are a popular choice in architecture due to their natural appearance and eco-friendly features. However, if the right selection and application are not made in harsh climate conditions, wooden surfaces can deteriorate quickly. In this article, we present a comprehensive guide on how to select and protect wooden facades that are resistant to severe climates.
Harsh climates include factors such as high humidity, extreme temperature changes, heavy rainfall, UV rays, and wind.Wooden buildings adapt to these conditions, maintaining both aesthetics and durability.. Properly selected and treated wooden products contribute to energy efficiency, protect the structure, and provide a long-term investment.
The materials and techniques to be used for wooden structures should be determined according to climate conditions.
Temperature changes can cause expansion and contraction in wood. High humidity and rainfall increase the risk of decay. Proper installation of cladding, decking, ceilings, and other exterior elements—along with adequate air circulation and effective water drainage—can significantly extend their lifespan and maintain structural integrity.
Thermally treated or chemically modified woods are more resistant to moisture and insect attacks. When selecting the wood species, hardness, density, and strength class should be considered.
Regular maintenance is essential for exterior applications. Renewing surface coatings and using protective oils or paints extend the life of the wood.
There are different wood types suitable for various climate conditions.
Thermowood and modified woods Heat-treated woods (thermowood) increase moisture resistance and maintain their form for a long time. Modified woods are strengthened against chemical and biological factors.
Hard tropical wood species Tropical woods such as teak, iroko, and merbau are resistant to water and insects thanks to their natural oils. However, it is important that these species are obtained from sustainable sources.
Certified sustainable sources Products certified by FSC and PEFC come from environmentally responsible forestry practices. This is an important criterion in terms of both quality and environmental responsibility.
The application method is as critical as the quality of the material.
Correctly fastening wooden boards, allowing for expansion gaps, and professionally finishing details ensure long-lasting use.
To prevent rainwater from damaging the facade, water drainage details and ventilated facade systems should be used. Allowing the wooden surface to breathe prevents deterioration.
With regular inspection, gentle cleaning, and periodic renewal of paint or oil, exterior applications can stay beautiful and durable for many years. This also keeps maintenance costs down
Wooden exteriors cost depends on what material you pick, how it’s treated, how it’s installed, and how much upkeep it’ll need. To keep things simple and affordable over time, plan for good quality, correct installation, and easy regular maintenance
Choosing the wrong wood species creates incompatibility with climate conditions.
Using uncertified or poor-quality products results in higher long-term costs.
Not leaving adequate ventilation gaps during installation increases the risk of moisture and decay.
