Traditional wood, while aesthetically pleasing, requires regular maintenance and often struggles under extreme weather conditions. At <em>BHB Bertsch HolzBau<\/em>, we rely on <strong>ThermoWood<\/strong> \u2013 thermally modified wood, which, due to its exceptional properties, has become our top choice for manufacturing <strong>decks for our wooden houses<\/strong>.<\/p>\n\n\n\n<p>Since we <strong>manufacture our ThermoWood decks in-house<\/strong>, we maintain full control over the quality and aesthetics of the final product. The raw material is sourced exclusively from <strong>renowned sawmills in Finland<\/strong>, a country known for its high-quality wood processing standards and pristine forests.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>What is ThermoWood?<\/strong><\/h2>\n\n\n\n<p>ThermoWood is wood that undergoes a special <strong>thermal modification process<\/strong>, which completely transforms its <strong>physical, chemical, and aesthetic properties<\/strong>. The process is carried out in a controlled atmosphere at high temperatures, <strong>without any chemical additives<\/strong>. The result is a material that is:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Highly resistant to moisture and changing weather conditions<\/strong>,<\/li>\n\n\n\n<li><strong>Dimensionally stable<\/strong> \u2013 it does not shrink or swell like untreated wood,<\/li>\n\n\n\n<li><strong>Naturally resistant to mold, fungi, and insects<\/strong>,<\/li>\n\n\n\n<li><strong>Eco-friendly<\/strong> \u2013 the process requires no chemical treatments,<\/li>\n\n\n\n<li><strong>Visually appealing<\/strong> \u2013 it retains the natural grain of the wood, and its color gradually develops an elegant patina over time.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>How is ThermoWood Made?<\/strong><\/h2>\n\n\n\n<p>The thermal modification process involves several steps:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Pre-drying<\/strong> \u2013 the wood is dried to the appropriate moisture content to prepare it for thermal treatment.<\/li>\n\n\n\n<li><strong>Heating in a steam atmosphere<\/strong> \u2013 the wood is exposed to high temperatures (180\u2013220\u00b0C), which changes its chemical structure.<\/li>\n\n\n\n<li><strong>Cooling and stabilization<\/strong> \u2013 the wood is slowly cooled, resulting in enhanced durability and dimensional stability.<\/li>\n<\/ol>\n\n\n\n<p>The final product is <strong>stronger, harder, and more resistant to external factors<\/strong> than conventional wood, while maintaining its <strong>natural appearance<\/strong>.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Why ThermoWood is Ideal for Decks<\/strong><\/h2>\n\n\n\n<p>A deck is a special space \u2013 it combines <strong>functionality, aesthetics, and comfort<\/strong>. The wood used for our decks must meet several critical requirements:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>1. Weather Resistance<\/strong><\/h3>\n\n\n\n<p>Decks are exposed to rain, snow, frost, sun, and temperature fluctuations. ThermoWood is <strong>resistant to moisture absorption<\/strong>, significantly reducing the risk of cracking, warping, or blistering.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>2. Dimensional Stability<\/strong><\/h3>\n\n\n\n<p>Traditional wood often shrinks or swells due to changes in humidity. ThermoWood maintains <strong>dimensional stability<\/strong>, ensuring the deck stays even and safe, and the boards do not \u201cmove\u201d unpredictably.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>3. Resistance to Pests and Fungi<\/strong><\/h3>\n\n\n\n<p>ThermoWood is <strong>naturally resistant to biological attacks<\/strong> \u2013 fungi, mold, and insects cannot develop in it. This ensures a long-lasting deck without the need for chemical treatments.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>4. Eco-friendliness and Safety<\/strong><\/h3>\n\n\n\n<p>At <em>BHB Bertsch HolzBau<\/em>, we prioritize <strong>healthy and ecological solutions<\/strong>. ThermoWood is processed <strong>entirely thermally, without chemical additives<\/strong>, making our decks fully safe for residents, children, and pets.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>5. Natural Beauty<\/strong><\/h3>\n\n\n\n<p>ThermoWood preserves the <strong>texture and character of natural wood<\/strong>, giving decks elegance and warmth. Over time, the wood develops a subtle patina that enhances charm and highlights the natural character of your outdoor space.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<div class=\"wp-block-group green-box\"><div class=\"wp-block-group__inner-container is-layout-constrained wp-block-group-is-layout-constrained\">\n<h2 class=\"wp-block-heading\"><strong>Why We Manufacture ThermoWood Decks In-House<\/strong><\/h2>\n\n\n\n<p>Producing decks in our own facility gives us <strong>full control over every step<\/strong> \u2013 from raw material selection to final assembly.
