This process, originally developed in Finland, transforms ordinary timber into a highly durable and stable material, making it ideal for use in exterior and humid construction environments. <\/p>\n<h1>Production Process and Thermowood Classes<\/h1>\n<p>The Thermowood production process comprises three key stages:<\/p>\n<ol>\n<li>High-Temperature Drying (Initial Drying): The wood&#8217;s moisture content is gradually reduced using heat and steam.<\/li>\n<li>Heat Treatment (Thermal Modification): The kiln temperature is raised to approximately 180 C to 220 C. At this temperature, the organic compounds and sugars in the wood structure, which act as a food source for fungi and insects, are degraded and eliminated. This process also changes the wood&#8217;s color to a deep, warm brown hue.  <\/li>\n<li>Cooling and Moisture Conditioning: The wood is cooled using cold water spray or steam, and its final moisture content is reduced to 4% to 6%.<\/li>\n<\/ol>\n<p>Classification Based on Temperature:<\/p>\n<p>Thermowood is primarily divided into two classes, each with distinct applications:<\/p>\n<ul>\n<li>Thermo-S (S stands for Stability):<br \/>Processed at approximately 180 C, offering higher dimensional stability.<br \/>Typically used for indoor and semi-exposed areas (e.g., furniture, doors, and windows).  <\/li>\n<li>Thermo-D (D stands for Durability):<br \/>Processed at approximately 212 C, providing much higher resistance to decay and harsh weather conditions.<br \/>The primary choice for exterior cladding, facades, and outdoor decking.  <\/li>\n<\/ul>\n<h1>Key Advantages of Thermowood in Construction<\/h1>\n<p>The thermal modification process alters Thermowood&#8217;s properties, making it a superior material in the building industry:<\/p>\n<ol>\n<li>High Resistance to Moisture and Decay: The wood&#8217;s equilibrium moisture content is drastically reduced, and the nutrients for fungi and bacteria are removed, making the wood highly resistant to biological attacks and rot.<\/li>\n<li>Dimensional Stability (Reduced Swelling and Shrinkage): Due to the complete removal of moisture, Thermowood is highly resistant to changes in ambient temperature and humidity, thus minimizing warping, swelling, or shrinking. This feature is critical for building facades exposed to weather elements. <\/li>\n<li>Thermal Insulation: The lower density and modified structure make the wood a relative thermal insulator, which contributes to the building&#8217;s energy savings.<\/li>\n<li>Environmental Compatibility: No toxic chemicals or preservatives are used in the Thermowood process, making it an eco-friendly product and safe for human health.<\/li>\n<li>Aesthetics and Uniform Color: The heat treatment transforms the wood&#8217;s color into a deep, uniform brown, lending a luxurious and natural appearance to the building.<\/li>\n<\/ol>\n<h1>Main Applications in the Building Industry<\/h1>\n<p>Given its outstanding properties, Thermowood has broad applications across various construction sectors:<\/p>\n<table>\n<thead>\n<tr>\n<td>Sector<\/td>\n<td>Application<\/td>\n<td>Key Feature<\/td>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Exterior Facade (Cladding)<\/td>\n<td>Main facade covering, gazebos, pergolas, louvers<\/td>\n<td>High resistance to sun, rain, moisture, and maintenance of dimensional stability.<\/td>\n<\/tr>\n<tr>\n<td>Outdoor Areas (Decking)<\/td>\n<td>Decking around swimming pools, villa grounds, roof gardens<\/td>\n<td>Resistance to moisture and direct water contact, free of chemicals.<\/td>\n<\/tr>\n<tr>\n<td>Humid Interior Spaces<\/td>\n<td>Saunas, bathrooms, shower cabins<\/td>\n<td>Excellent resistance to high humidity and temperatures in sauna environments and low heat transfer.<\/td>\n<\/tr>\n<tr>\n<td>Interior Decoration<\/td>\n<td>Wall coverings, ceiling panels, flooring<\/td>\n<td>Natural beauty, warm color, and easy workability.<\/td>\n<\/tr>\n<tr>\n<td>Structural Components<\/td>\n<td>Railings, fencing, doors, and windows<\/td>\n<td>Durability and stability against weather conditions.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2>Important Notes on Use and Maintenance<\/h2>\n<ul>\n<li>UV Discoloration: If Thermowood is exposed to direct sunlight (UV radiation) and not protected with a specialized protective oil or stain, it will gradually lose its brown color and turn into a natural silver-grey hue. This color change is not an indication of decay, but periodic coatings are required to preserve the original color. <\/li>\n<li>Proper Installation: The installation of Thermowood on a facade must ensure an appropriate gap from the substrate (for air ventilation) and use stainless and standard fasteners (such as concealed clips or specialized screws).<\/li>\n<li>Initial Cost: Due to the specialized production process, Thermowood has a higher initial price than conventional timbers or some other materials, but its long lifespan and minimal maintenance justify this cost in the long run.<\/li>\n<\/ul>\n<h1>Conclusion<\/h1>\n<p>By modifying the natural structure of wood and significantly enhancing its durability and stability, Thermowood makes it possible to enjoy the beauty and warmth of timber in the harshest environmental conditions. This material has become a key element in modern and luxurious designs, contributing not only to visual appeal but also significantly to the longevity and sustainability <\/p>\n<h3>For more information about the rules and costs related to exports, imports, supply of goods, and receiving advice, you can call +37495447044<\/h3>\n<h3>To view related products, please visit the <a href=\"https:\/\/eaeubm.com\/en\/product-category\/plastering\/\">Eurasia store website<\/a>.<\/h3>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>What is Thermowood?
