The upstand specially designed for use as a smoke extraction system
The metal RAK/TE upstands are particularly well suited as basic elements for use as SHEV system in industrial flat roofs, which have been proven in practice.
Due to their aerodynamically favourable geometry, they make an effective contribution to preventive fire protection in an energetically simpler surrounding.
The RAK model metal upstand from VELUX Commercial provides a safe connection for both bituminous and high polymer roofing membranes. Thermal insulation is provided by 30mm mineral wool.
The TE model metal upstand from VELUX Commercial also contains 30mm mineral wool and is supplied with an E-clamping rail that can be mechanically screwed into the roof membrane in the upstand incline.
