GFRP aluminium composite AK upstand

The right solution for flat metal roofs

If you are looking for the right upstand for use in flat metal roofs, such as thermal or insulated roofs, then the GFRP aluminium composite upstands offer a versatile basic element.

The proven GFRP upstands optimally combine the various requirements – e.g. SHEV functionality and energy efficiency. You also have a choice of insulation thicknesses to make your upstand even more energy-efficient.

The GFRP aluminium composite AK upstand consists of a GFRP upstand with flat flange for thermal separation with thermally insulated reveal and a welded frame made of aluminium sheet. Both elements can be coated in a RAL colour of your choice, so that they are ideally adapted to the design of your building.
