It is what can be preserved, improved and used safely for longer.<\/p>\n<p>This way of thinking also applies to ventilation ducts.<\/p>\n<p>In both the renovation of existing ventilation ducts and the construction of new ductwork, airtightness, cleanliness, durability and long service life are becoming increasingly important factors.<\/p>\n<div style=\"background: #f5f5f5; border-left: 4px solid #222; padding: 18px 22px; margin: 25px 0;\"><strong>A ventilation duct does not always need to be replaced. In many cases, its service life can be extended safely by sealing, coating and protecting it.<\/strong><\/div>\n<h2>Replacing ventilation ducts is not always the only solution<\/h2>\n<p>In many buildings, demolishing and replacing old ventilation ducts can have a significant impact on the use of the entire building.<\/p>\n<p>Demolition may involve, for example:<\/p>\n<ul>\n<li>long interruptions in use<\/li>\n<li>extensive demolition work<\/li>\n<li>high material costs<\/li>\n<li>high carbon dioxide emissions<\/li>\n<li>disruption to building users<\/li>\n<li>the need for temporary facilities or restrictions on the use of spaces<\/li>\n<\/ul>\n<p>However, replacement is not always the best option from a technical, financial or environmental perspective. In many cases, the service life of existing ductwork can be extended responsibly.<\/p>\n<p>Sealing and coating ventilation ducts can make it possible to:<\/p>\n<ul>\n<li>reduce air leaks<\/li>\n<li>improve energy efficiency<\/li>\n<li>make ventilation balancing easier<\/li>\n<li>provide corrosion protection for ductwork<\/li>\n<li>encapsulate fibres<\/li>\n<li>manage hazardous substances<\/li>\n<li>extend service life by decades<\/li>\n<\/ul>\n<p>Especially in hospitals, schools, office buildings, industrial facilities and residential properties, this can help avoid extensive demolition work and reduce the impact of renovation on building users.<\/p>\n<h2>Three reasons to assess duct renovation before deciding on replacement<\/h2>\n<div style=\"background: #f5f5f5; padding: 25px; margin: 30px 0;\">\n<div style=\"display: grid; grid-template-columns: repeat(auto-fit, minmax(230px, 1fr)); gap: 18px;\">\n<div style=\"background: #ffffff; padding: 20px; border: 1px solid #e0e0e0;\">\n<h3 style=\"margin-top: 0;\">1. Less demolition<\/h3>\n<p>When existing ductwork can be preserved, demolition waste, material waste and disruption to building use can be reduced.\n<\/p><\/div>\n<div style=\"background: #ffffff; padding: 20px; border: 1px solid #e0e0e0;\">\n<h3 style=\"margin-top: 0;\">2. Better airtightness<\/h3>\n<p>Sealed ductwork helps reduce air leaks and makes it easier to adjust the ventilation system to the intended performance level.\n<\/p><\/div>\n<div style=\"background: #ffffff; padding: 20px; border: 1px solid #e0e0e0;\">\n<h3 style=\"margin-top: 0;\">3. Longer service life<\/h3>\n<p>Coating and protection can improve duct durability, protect against corrosion and extend the life cycle of the system.\n<\/p><\/div>\n<\/div>\n<\/div>\n<h2>Hazardous substances in ventilation ducts can also be managed without demolition<\/h2>\n<p>Various impurities and types of damage can be found in old ventilation ducts. These may include, for example:<\/p>\n<ul>\n<li>mineral fibres<\/li>\n<li>PAH compounds<\/li>\n<li>creosote<\/li>\n<li>VOC compounds<\/li>\n<li>corrosion damage<\/li>\n<li>microbial impurities<\/li>\n<\/ul>\n<p>However, replacing all ducts is not always necessary.<\/p>\n<p>Encapsulation and coating of ventilation ducts can enable hazardous substances to be managed and the system to be used safely without heavy demolition work. When impurities can be controlled through encapsulation and the ductwork can be coated with a suitable system, both costs and environmental impact can be reduced.<\/p>\n<div style=\"background: #f5f5f5; border-left: 4px solid #222; padding: 18px 22px; margin: 25px 0;\"><strong>The discovery of hazardous substances in ventilation ducts does not automatically mean that the entire duct system must be replaced. First, it is worth determining whether the risk can be safely managed through encapsulation and coating.<\/strong><\/div>\n<h2>In new ventilation ducts, airtightness and long service life are essential<\/h2>\n<p>The airtightness of ventilation ducts directly affects how well a building functions and how much it costs to operate.<\/p>\n<p>Airtightness has an impact on:<\/p>\n<ul>\n<li>energy efficiency<\/li>\n<li>indoor air quality<\/li>\n<li>ventilation adjustment and balancing<\/li>\n<li>building operating costs<\/li>\n<li>the life cycle of the system<\/li>\n<\/ul>\n<p>Leaking ductwork increases energy consumption and makes ventilation balancing more difficult. It can also reduce system predictability and place unnecessary strain on ventilation performance.<\/p>\n<p>That is why it is increasingly important to ask:<\/p>\n<div style=\"background: #f5f5f5; border-left: 4px solid #222; padding: 18px 22px; margin: 25px 0;\"><strong>How can the airtightness of new ventilation ducts be ensured throughout their entire service life?<\/strong><\/div>\n<p>From TKR\u2019s perspective, sealing duct joints, penetrations and critical points already during installation can:<\/p>\n<ul>\n<li>improve airtightness<\/li>\n<li>reduce air leaks<\/li>\n<li>make system adjustment easier<\/li>\n<li>prevent corrosion<\/li>\n<li>improve system durability<\/li>\n<li>reduce life cycle costs<\/li>\n<\/ul>\n<p>The long service life of ventilation ducts is especially important in energy-efficient buildings, hospitals, cleanroom environments, solid timber buildings and industrial properties.<\/p>\n<h2>Extending the service life of buildings is also a climate action<\/h2>\n<p>The environmental impact of a building is not created only by energy consumption during use.<\/p>\n<p>Significant emissions are also caused by:<\/p>\n<ul>\n<li>the manufacture of materials<\/li>\n<li>transportation<\/li>\n<li>demolition work<\/li>\n<li>construction waste<\/li>\n<li>the construction of new structures<\/li>\n<\/ul>\n<p>When the service life of existing structures can be extended, the overall environmental impact of construction can also be reduced. This also applies to ventilation ducts.<\/p>\n<p>Duct renovation, sealing and coating can be part of a broader approach to responsible renovation, where a building is not treated as a disposable whole but as a long-lasting resource.<\/p>\n<h2>Preserving structures supports circular economy<\/h2>\n<p>The aim of building maintenance is not to preserve poor-quality or unsafe structures at any cost.<\/p>\n<p>The goal is to find technically safe solutions that can:<\/p>\n<ul>\n<li>extend the service life of structures<\/li>\n<li>reduce the need for demolition<\/li>\n<li>lower the carbon footprint<\/li>\n<li>save natural resources<\/li>\n<li>improve energy efficiency<\/li>\n<li>preserve the value of buildings<\/li>\n<\/ul>\n<p>This is circular economy in practice.
