insulation<\/h2>\n<p>The thickness of the layer, which the insulation of ventilation ducts should have, is of essential importance. The key issue here is the location of the installation ducts. And so an unheated area requires a thicker insulation than, for example, a space in a suspended ceiling. The thickness of the insulation layer is also affected by the air circulation in the close vicinity of the ventilation duct. In this case, even slight air movement requires thicker thermal protection. In other words, when providing insulation, it is very important to correctly determine the circumference of the insulated duct, and to be as precise and careful as possible when laying the insulation.<\/p>\n<p>To maintain full fire protection, the ventilation duct insulation should be made of non-flammable materials with a low thermal conductivity coefficient. They should also be characterized by high resistance to external factors, especially to water due to the fact that huge problems occur when condensation builds up on the outside of ducts containing material with a lower temperature than the ambient air temperature. With high humidity, the air can easily condense on the outer surface of ducts. When this happens, water starts to drip and causes damage, such as discoloration to ceilings and floors. Over time, water can cause damage to the ducts and reduce their service life.<\/p>\n<p>On the other hand, Ventilation system equipment and the sound of air moving through ducts can produce a lot of unwanted noise, which usually needs to be attenuated. Consequently, PUF is used more and more frequently, which is assembled on the internal surface of the ventilation duct.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-9d3a1c3 e-flex e-con-boxed e-con e-parent\" data-id=\"9d3a1c3\" data-element_type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-2b33aef elementor-widget elementor-widget-image\" data-id=\"2b33aef\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img fetchpriority=\"high\" decoding=\"async\" width=\"960\" height=\"451\" src=\"https:\/\/imenpol.com\/blog\/en\/wp-content\/uploads\/sites\/2\/2025\/06\/Air-conditioning-insulation-feature.jpg\" class=\"attachment-full size-full wp-image-17417\" alt=\"Air conditioning insulation feature\" srcset=\"https:\/\/imenpol.com\/blog\/en\/wp-content\/uploads\/sites\/2\/2025\/06\/Air-conditioning-insulation-feature.jpg 960w, https:\/\/imenpol.com\/blog\/en\/wp-content\/uploads\/sites\/2\/2025\/06\/Air-conditioning-insulation-feature-300x141.jpg 300w, https:\/\/imenpol.com\/blog\/en\/wp-content\/uploads\/sites\/2\/2025\/06\/Air-conditioning-insulation-feature-768x361.jpg 768w\" sizes=\"(max-width: 960px) 100vw, 960px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-09c515c  table-contents e-flex e-con-boxed e-con e-parent\" data-id=\"09c515c\" data-element_type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-53c6366 elementor-widget elementor-widget-text-editor\" data-id=\"53c6366\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\n\n\n\n\n<h2>Polyurethane foam pre-insulated duct panel air duct<\/h2>\n<p>The panels can be fabricated into different kinds of shapes by cutting and adhesive connecting.
