September 12th, 2021. In the Working Group Warm Edge of the BF, for the collective project on the usability of warm edge systems, spacers were divided into five categories based on EN 1279-1, Section 3, Figure 2 (see also ift guideline VE-17\/1) :<\/p>\n
Category A<\/strong><\/span> = fully metallic hollow profiles (e.g. profiles made of aluminum, galvanized steel or stainless steel) * According to Section 3.24 of EN 1279-1, the adhesion surface of a spacer is considered to be “metallic” if it is made of rolled or extruded aluminum, galvanised steel, stainless steel, without organic surface treatment. According to Note 1 to the term, organic surface treatments are painting, organic coating, organic film or organic overspray.<\/p>\n","protected":false},"excerpt":{"rendered":" September 12th, 2021.
