Insulation material covering the upper surface of ECOPAN panel is a mineral wool mat, 40 mm thick, covered on the top by an aluminium foil. ECOPAN, after a careful analysis, has chosen hanging brackets with rectangular cross section, whose height is particularly reduced. This solution allows placing the insulation mats quickly and homogeneously, making the glass wool adhere perfectly to the metal sheet. This adherence is even improved by the use of fastening rods on the top. In order to contain at sides and hide the insulation mat, side edges of ECOPAN panels are obtained from the same radiant plate. They also make laying the insulation faster and more precise.
