Here, the waterproofing membrane is directly applied over the structural deck, also acting as a vapour control layer (VCL).<\/li>\n<li><strong>Installation method:<\/strong> Unlike warm roofs, inverted roofs use loose-laid insulation and therefore finishes\/loads on top are required to prevent wind uplift.<\/li>\n<li><strong>Insulation challenges:<\/strong> Inverted roof insulation faces moisture exposure and varying loads, requiring water-resistant and robust materials.<\/li>\n<li><strong>Rainwater management:<\/strong> In inverted roof applications, a Water Flow Reducing Layer (WFRL) is installed over the thermal insulation to reduce the rainwater ingress.<\/li>\n<\/ul>\n<p>Choosing the right insulation material is crucial for long-term durability and compliance with building regulations.<\/p>\n<h3>Enhanced fire safety in inverted roofs<\/h3>\n<p>FOAMGLAS\u00ae inverted roof insulation is <a href=\"https:\/\/www.foamglas.com\/en-gb\/invatherm?utm_source=pbctoday-website&amp;utm_medium=article&amp;utm_campaign=FG-B-INVERTEDROOFSCAMPAIGN-UK&amp;utm_content=link1\" target=\"_blank\" rel=\"noopener\">non-combustible<\/a> and suitable for terraces, podiums, green roofs and more.<\/p>\n<p>FOAMGLAS\u00ae INVATHERM\u2122, as part of the inverted roof system, consists of cellular glass with a pre-applied inorganic coating on the upper surface. Both the core material and the coating have <a href=\"https:\/\/www.foamglas.com\/en-gb\/invatherm?utm_source=pbctoday-website&amp;utm_medium=article&amp;utm_campaign=FG-B-INVERTEDROOFSCAMPAIGN-UK&amp;utm_content=link3\" target=\"_blank\" rel=\"noopener\">an A1 fire reaction classification<\/a>, making them fire-resistant.
