The former contain fire-retardant or flame-retardant additives (from the Latin *ignis*, meaning \u2018fire\u2019, and *fugo*, meaning \u2018that which causes to flee\u2019); the latter are formulated with intumescent additives (from the Latin *intumescens*, the present participle of *intumescere*, meaning \u2018to swell\u2019). At temperatures between 200 and 300\u00b0C, fire-retardant additives release oxygen-inhibiting substances: they produce carbon dioxide or generate water vapour, thereby effectively lowering the combustion temperature. Between 300 and 400\u00b0C, fire-retardant coatings begin the crystallisation process. Essentially, a non-flammable vitrified layer creates a barrier for the wood.\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-bafba88 e-flex e-con-boxed e-con e-parent\" data-id=\"bafba88\" data-element_type=\"container\" data-e-type=\"container\" data-settings=\"{&quot;background_background&quot;:&quot;classic&quot;}\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-c2dc8e6 e-flex e-con-boxed e-con e-parent\" data-id=\"c2dc8e6\" data-element_type=\"container\" data-e-type=\"container\" data-settings=\"{&quot;background_background&quot;:&quot;classic&quot;}\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t<div class=\"elementor-element elementor-element-cf318f3 e-con-full e-flex e-con e-child\" data-id=\"cf318f3\" data-element_type=\"container\" data-e-type=\"container\" data-settings=\"{&quot;background_background&quot;:&quot;classic&quot;}\">\n\t\t\t\t<div class=\"elementor-element elementor-element-607a642 elementor-widget elementor-widget-heading\" data-id=\"607a642\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Protective\nand insulating barrier<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-fc7fba4 elementor-widget__width-initial elementor-widget elementor-widget-text-editor\" data-id=\"fc7fba4\" data-element_type=\"widget\" data-e-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\tIntumescent additives react at 200\u00b0C by causing the coating film to swell. In this way, they create a protective and insulating barrier, delaying both combustion and the rise in temperature. Flame-retardant additives are normally used in coating systems applied to furniture, whilst the more reactive \u2013 but aesthetically less transparent \u2013 intumescent additives are incorporated into coatings used for load-bearing structures and coatings classified according to the European fire reaction standard. Therefore, a fire-retardant coating certified to Class 1 of the European Fire Reaction Classification will contain flame-retardant additives and will be more transparent and offer better performance, such as chemical and abrasion resistance, whilst a intumescent coating certified to a European Fire Resistance or Fire Reaction Class will be significantly less transparent and more sensitive to moisture and mechanical stress.\t\t\t\t\t\t\t\t<\/div>\n\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-4e4f92d e-flex
