GRP upstand

The all-rounder among the upstands

The GRP upstands can be utilised for a wide range of applications and can be connected to bituminous and plastic roof membranes as well as to trapezoidal profiles and/or corrugated profiles and ISO roofs by means of appropriate flange formations.

Due to the (optionally available) circumferential adhesive fixing flange, there is always a secure connection to high-polymer roof waterproofing. The upstands are additionally equipped with atleast 20mm thermal insulation, which can also be supplied in thicknesses of 40, 60, 80 or 100 mm where required. The GRP upstands can additionally be supplied with an overhang strip.

For use as a SHEV system you can choose between the RAK upstand geometry for maximum aerodynamicextraction values (Aa values) or EURO for improved thermal insulation properties.
