PVC AK upstand

The classic upstand for industrial flat roofs

The PVC AKs are our classic upstand models. They are double-walled with a sturdy inner K-bracing geometry made of white construction plastic (extruded) and a circumferentially moulded nosefor hanging in the -OPTIMAL roof connection system (optional). The corners are made waterproof through mirror- welding.These upstands look perfect due to the smooth internal wall, and they can be used for all SHEV dome rooflights, darkening flaps and VARIO light flaps.

They also provide excellent thermal insulation values due to profile chambers completely filled with polystyrene foam. This permits a heat transmission coefficient of U_{N, UP} = 0.85 W/m²K according to DIN EN 6946 without problems.
