Given that mold can cause health problems as well as structural damage it\u2019s important to understand the conditions that cause mold growth, so that they can be avoided.<\/p>\n<p>This is a particular concern for the owners of buildings, caravans, boats and outbuildings, especially those left unoccupied or unheated for any period of time.<\/p>\n<h3>The Effects of Mold<\/h3>\n<p>It\u2019s well known that mold will quickly spoil soft furnishings, fabrics, leather and similar materials. But it can also cause structural damage to buildings, weakening walls and floors and causing leaks. This can include not just organic materials like wood, but also damage to brickwork, plaster and concrete.<\/p>\n<p>Even more importantly, mold can cause serious health problems for people living and working in affected areas. It can aggravate asthma and other respiratory ailments, cause coughing, rashes and eye complaints and some molds are even directly toxic through their spores. The presence of mold is also frequently linked to Sick Building Syndrome.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-14375\" src=\"https:\/\/lascarelectronics.com\/intl\/wp-content\/uploads\/mould-on-the-wall.jpg\" alt=\"mould on the wall\" width=\"1200\" height=\"630\" srcset=\"https:\/\/lascarelectronics.com\/intl\/wp-content\/uploads\/mould-on-the-wall.jpg 1200w, https:\/\/lascarelectronics.com\/intl\/wp-content\/uploads\/mould-on-the-wall-300x158.jpg 300w, https:\/\/lascarelectronics.com\/intl\/wp-content\/uploads\/mould-on-the-wall-1024x538.jpg 1024w, https:\/\/lascarelectronics.com\/intl\/wp-content\/uploads\/mould-on-the-wall-768x403.jpg 768w, https:\/\/lascarelectronics.com\/intl\/wp-content\/uploads\/mould-on-the-wall-120x63.jpg 120w, https:\/\/lascarelectronics.com\/intl\/wp-content\/uploads\/mould-on-the-wall-990x520.jpg 990w, https:\/\/lascarelectronics.com\/intl\/wp-content\/uploads\/mould-on-the-wall-441x232.jpg 441w, https:\/\/lascarelectronics.com\/intl\/wp-content\/uploads\/mould-on-the-wall-800x420.jpg 800w, https:\/\/lascarelectronics.com\/intl\/wp-content\/uploads\/mould-on-the-wall-150x79.jpg 150w\" sizes=\"auto, (max-width: 1200px) 100vw, 1200px\" \/><\/p>\n<h3>Factors in Mold Growth<\/h3>\n<p>Mold requires four things to grow: nutrients, moisture, an acceptable temperature range, and time. It can use most organic materials as a food source, including house dust, and so cleanliness is an important factor. However it is a combination of moisture and temperature that most frequently creates the conditions for mold to flourish.<\/p>\n<p>Rooms and buildings that are airtight or have poor ventilation often experience high rates of mold growth because moisture is trapped within them. Conversely, if there is too much airflow from outside, moisture can be drawn into the space and again growth occurs.<\/p>\n<p>It\u2019s therefore necessary that balanced ventilation is provided. Keeping humidity levels low can also discourage pests such as dust mites and cockroaches.<\/p>\n<h3>Material Sensitivity to Mold Growth<\/h3>\n<p>As already noted, mold can grow on almost any material, but it will grow much faster on some materials than others. Fast growth will normally happen on organic surfaces, but if nutrients are available mold can grow slowly even on glass and metal.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-11795\" src=\"https:\/\/lascarelectronics.com\/intl\/wp-content\/uploads\/Mould-Graph-300x170.jpg\" alt=\"mould graph\" width=\"1032\" height=\"585\" srcset=\"https:\/\/lascarelectronics.com\/intl\/wp-content\/uploads\/Mould-Graph-300x170.jpg 300w, https:\/\/lascarelectronics.com\/intl\/wp-content\/uploads\/Mould-Graph-1024x580.jpg 1024w, https:\/\/lascarelectronics.com\/intl\/wp-content\/uploads\/Mould-Graph-768x435.jpg 768w, https:\/\/lascarelectronics.com\/intl\/wp-content\/uploads\/Mould-Graph-120x68.jpg 120w, https:\/\/lascarelectronics.com\/intl\/wp-content\/uploads\/Mould-Graph-990x561.jpg 990w, https:\/\/lascarelectronics.com\/intl\/wp-content\/uploads\/Mould-Graph-441x250.jpg 441w, https:\/\/lascarelectronics.com\/intl\/wp-content\/uploads\/Mould-Graph-800x453.jpg 800w, https:\/\/lascarelectronics.com\/intl\/wp-content\/uploads\/Mould-Graph-150x85.jpg 150w, https:\/\/lascarelectronics.com\/intl\/wp-content\/uploads\/Mould-Graph.jpg 1200w\" sizes=\"auto, (max-width: 1032px) 100vw, 1032px\" \/><\/p>\n<h3>Monitoring Ambient Conditions<\/h3>\n<p>Even after precautions are taken to reduce mold growth, the ambient temperature and humidity within an enclosed space will naturally vary and it\u2019s important to know whenever conditions for fast growth occur. For this reason, monitoring temperature and humidity is as important for the health of a building as ensuring adequate ventilation.<\/p>\n<p>Modern Cloud-based monitoring systems are an inexpensive way to continuously monitor a single location, or multiple buildings or areas within a building. As well as providing up to date readings, long-term and seasonal data trends can be viewed and analyzed. When condensation occurs the sudden spike in moisture can trigger mold growth.<\/p>\n<p>For this reason the monitoring system should also measure the dew point, which is the combination of temperature and humidity at which condensation starts. A good system will also provide live notifications whenever pre-set measurement levels are reached.<\/p>\n<p>For mold growth the most critical parameter is humidity, and it\u2019s recommended that this alarm level should be set to 60% so that the building can be checked as soon as atmospheric moisture reaches this point.<\/p>\n<h3>References:<\/h3>\n<p>World Health Organization Guidelines For Indoor Air Quality<br \/>\n<strong>Available at<\/strong>: <a href=\"https:\/\/www.euro.who.int\/__data\/assets\/pdf_file\/0017\/43325\/E92645.pdf\" target=\"_blank\" rel=\"noopener\">https:\/\/www.euro.who.int\/__data\/assets\/pdf_file\/0017\/43325\/E92645.pdf<\/a><\/p>\n<p>Extent of Moisture and Mould Damage in Structures of Public Buildings<br \/>\n<strong>Available at:<\/strong> <a href=\"https:\/\/www.sciencedirect.com\/science\/article\/pii\/S2214509516300833 VTT\" target=\"_blank\" rel=\"noopener\">https:\/\/www.sciencedirect.com\/science\/article\/pii\/S2214509516300833 VTT<\/a><\/p>\n<p>Research Center Workshop on Mould Risk Evaluation<br \/>\n<strong>Available at:<\/strong> <a href=\"https:\/\/web.ornl.gov\/sci\/buildings\/2016\/docs\/presentations\/workshops\/workshop-5\/Workshop5_OjanenViitanen_Eqs.pdf\" target=\"_blank\" rel=\"noopener\">https:\/\/web.ornl.gov\/sci\/buildings\/2016\/docs\/presentations\/workshops\/workshop-5\/Workshop5_OjanenViitanen_Eqs.pdf<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>It can take as little as four weeks for mold to grow to a damaging extent on a surface that was previously clean, dry and unblemished.
