JET-STEEL-ALU-COMPOSITE-AK Upstand

The perfect upstand for flat metal roofs

The JET-STEEL-ALU-COMPOSITE upstands are the ideal basic elements for use in flat metal roofs (e.g. thermal or insulated roofs) and have proven themselves in use for many years.

They consist of steel on the inside and aluminium on the outside as well as a thermal separator strip and flat adhesive base flange. This upstand is equipped with 60 mm mineral wool for high thermal insulation.

The JET-STEEL-ALU-COMPOSITE upstands optimally combine the various requirements such as SHEV function and energy efficiency and can therefore be used in a variety of ways.
