ISO-THERM AK upstand

The energy-efficient upstand innovation for flat roofs

The ISO-THERM AK is the solution when you need a particularly well insulated upstand. The PVC shiplap framework the upper upstand connection is free of thermal bridges and insulated. The 60mm mineral wool provides excellent thermal insulation.

ISO-THERM upstands have proven themselves as versatile basic elements used in both new buildings and refurbishment projects. They have not only been shown to be very energy-efficient, but also support the self-cleaning effect of flat glass products (optionally with an integrated 7° slope).

The upstand is supplied with an E-clamping rail that can be mechanically screwed to the roof membrane in the upstand incline.
