It can reduce visibility, affect thermal insulation and encourage the growth of mould around windows. To preserve the efficiency of glazing and ensure a healthy indoor environment, it&#8217;s essential to understand the causes of condensation and apply appropriate solutions.  <\/p>\n\n<h2 class=\"wp-block-heading\">1. Why does condensation form on glazing?<\/h2>\n\n<p class=\"wp-block-paragraph\">Condensation occurs when warm, moist air inside a building comes into contact with a cold surface, such as glazing. When the humidity in the air reaches its dew point, it forms water droplets on the glass. <\/p>\n\n<p class=\"wp-block-paragraph\">There are three types of condensation:<\/p>\n\n<ul class=\"wp-block-list\">\n<li>Indoor condensation: occurs inside the building, usually due to poor ventilation.<\/li>\n\n\n\n<li>Exterior condensation: visible on the outside of the glazing, often due to temperature differences between the ambient air and the glass.<\/li>\n\n\n\n<li>Condensation between panes: this concerns double- or triple-glazed units with inadequate sealing.<\/li>\n<\/ul>\n\n<h2 class=\"wp-block-heading\">2. Solutions to prevent indoor condensation<\/h2>\n\n<h3 class=\"wp-block-heading\">Improve ventilation<\/h3>\n\n<p class=\"wp-block-paragraph\">A lack of air circulation encourages the build-up of humidity inside the home.<\/p>\n\n<ul class=\"wp-block-list\">\n<li>Air every day: open the windows at least 10 to 15 minutes a day, even in winter.<\/li>\n\n\n\n<li>Install a CMV (controlled mechanical ventilation): this ensures constant air renewal and limits humidity build-up.<\/li>\n\n\n\n<li>Use air extractors in damp rooms such as kitchens and bathrooms.<\/li>\n<\/ul>\n\n<h3 class=\"wp-block-heading\">Regulating ambient humidity<\/h3>\n\n<p class=\"wp-block-paragraph\">Excessive humidity promotes condensation on glass.<\/p>\n\n<ul class=\"wp-block-list\">\n<li>Maintain humidity levels between 40 and 60% using a hygrometer.<\/li>\n\n\n\n<li>Install a dehumidifier in rooms prone to humidity.<\/li>\n\n\n\n<li>Avoid drying clothes indoors without adequate ventilation.<\/li>\n<\/ul>\n\n<h3 class=\"wp-block-heading\">Properly insulate windows<\/h3>\n\n<p class=\"wp-block-paragraph\">Poorly insulated glazing cools more quickly, increasing the risk of condensation.<\/p>\n\n<ul class=\"wp-block-list\">\n<li>Choose high-performance double or triple glazing, with a space filled with argon gas to limit heat exchange.<\/li>\n\n\n\n<li>Check the condition of window seals and frames to prevent cold air infiltration.<\/li>\n\n\n\n<li>Add thermal curtains to limit glazing cooling at night.<\/li>\n<\/ul>\n\n<h2 class=\"wp-block-heading\">3. Solutions to prevent external condensation<\/h2>\n\n<p class=\"wp-block-paragraph\">Exterior condensation is a normal phenomenon on high-performance glazing, as it reduces heat exchange between inside and outside. However, there are ways to limit its impact: <\/p>\n\n<ul class=\"wp-block-list\">\n<li>Use glazing with an anti-condensation treatment, which prevents the formation of droplets by distributing the temperature more evenly over the glass surface.<\/li>\n\n\n\n<li>Plant hedges or install external protection, such as roller shutters, to reduce direct exposure of glazing to temperature variations.<\/li>\n<\/ul>\n\n<h2 class=\"wp-block-heading\">4. Solutions to prevent condensation between glass panes<\/h2>\n\n<p class=\"wp-block-paragraph\">If condensation appears between the panes of a double- or triple-glazed unit, this means that the glazing has failed to seal properly. In this case, the only solution is to replace the glazing, as the gaseous insulation between the layers of glass no longer plays its role. <\/p>\n\n<h2 class=\"wp-block-heading\">Conclusion<\/h2>\n\n<p class=\"wp-block-paragraph\">Condensation on security glazing is a common problem that can be avoided with good ventilation, effective humidity control and well-insulated glazing. If condensation appears between the panes, replacement is necessary. <\/p>\n\n<p class=\"wp-block-paragraph\">To find out more about high-performance glazing solutions and avoid condensation, visit our page dedicated to<a href=\"https:\/\/leaderservices.be\/en\/security\/glazing\/\"> glazing services<\/a>.
